Student Loan Consolidation

Student loan consolidation allows you to combine one or more of your federal education loans into a new loan that offers you several advantages.
Lower Interest Rate For In-School and In-Grace Consolidation Borrowers who have a Direct Loan or FFEL loan in an in-school or grace period at the time we receive their consolidation application, may benefit from a lower fixed interest rate on the new Direct Consolidation Loan. The difference between a borrower's interest rate during their in-school and/or grace period and during their repayment period can be as high as 0.6 percentage points.
In-school consolidation is available only with Direct Consolidation Loans.
One Lender and One Monthly Payment With only one lender and one monthly bill, you will find it is easier to manage your debt. You will have only one lender, the U.S. Department of Education, for all loans included in your Direct Consolidation Loan.
Flexible Repayment Options You can choose from four different plans to repay your Direct Consolidation Loan, including an Income Contingent Repayment Plan. These plans are flexible to meet the different needs of borrowers. With a Direct Consolidation Loan, you can switch repayment plans at anytime. Grace Period If you consolidate while in-school, you may receive a 6-month grace period before repayment begins.
No Minimum or Maximum Loan Amounts or Fees Direct Consolidation Loans do not exclude anyone based on the size of their loan debt! In addition, consolidation is free. Varied Deferment Options Direct Consolidation Loans offer several deferment options. If you have exhausted the deferment options on your current Federal education loans, a Direct Consolidation Loan could renew those deferment options. In addition, you may be eligible for additional deferment options if you have an outstanding balance on an FFEL made before July 1, 1993, when you obtain your first Direct Loan. Reduced Monthly Payments A Direct Consolidation Loan may lower your monthly payment. The minimum monthly payment on a Direct Consolidation Loan may be lower than the payments on your federal education loans.
Retention of Subsidy Benefits You will keep any subsidies on your old loans.
What are the interest rates on your loans? If a Federal Consolidation Loan offers you a lower rate than your current loans, you may want to consolidate. Currently, the interest rate for a Federal Consolidation Loan is based on the weighted average interest rate on the loans being consolidated, rounded to the next nearest higher one-eighth of one percent. This rate is fixed for the life of the loan and cannot exceed 8.25 percent. Use our online calculator to find out what your weighted average interest rate would be if you consolidate with us.
Are your monthly payments manageable? If you have trouble meeting your monthly payments, have exhausted your deferment and forbearance options, and/or want to avoid default, consolidation may help you. Use our online calculator to find out what your monthly payments would be under each of our repayment plans.
How much are you willing to pay over the long term? Like a home mortgage or a car loan, extending the years of repayment increases the total amount you have to repay.
How many payments do you have left on your loans? If you are close to paying off your student loans, it may not be worth the effort to consolidate or extend your payments.
What consolidation loan benefits do your current lenders offer? Check with the loan holders currently servicing your loans to see if they can offer terms and repayment plans that meet your needs better than a Direct Consolidation Loan.

Why to Consolidate?

Both federal student loan consolidation and private student loan consolidation offer the benefit of a significantly lower monthly payment and simplified finances. If you want to consolidate student loans, begin with your federal Stafford, Parent PLUS, Perkins, and all Federal FFELP and Federal Direct Loans that were taken out for your education. Private student loan consolidation is a separate program that allows you to refinance all non-federal, education related debt.

Keeping supersonic transport quiet

Supersonic business jets have traditionally got a bad rap when it comes to practicality and the environment, with high costs, loud noises and short range far outweighing the benefits of speed. The future of air travel will therefore be subject to stringent criteria to ensure that economy and eco-credentials, particularly noise pollution, don’t take a back seat to comfort and performance, and with this in mind Supersonic Aerospace International seem to have hit a luxury-class balance between the two.Its QSST (Quiet Supersonic Transport) could well be the future of high-speed passenger jets and the concept pictured above boasts some impressive figures. It promises to be 100 times quieter than the Concorde with a range of over 4000 nautical miles and a top speed of Mach 1.8, or 1,188 miles per hour. To put this in context – a typical 9.5 hour flight from Seattle to Tokyo in a commercial aircraft would be reduced to under five hours in the QSST.Its patented design makes it possible to fly over populated continental areas with a sonic signature of just 65 DMA, or little louder than the interior of a car traveling at 70mph. This is achieved through a combination of the aerodynamic shaping of the ‘v-tail’ and state-of-the-art engine design to suppress takeoff and landing noise. It will also meet or exceed emission standards with clean-burning engines designed to reduce emissions during a high-altitude cruise.Intended primarily for government and business use, the QSST compares favorably to current commercial and business jets, accommodating up to 12 passengers in executive level comfort.Though there is still a lot of work to be done at the design stage, SAI is confident that once an international consortium is confirmed to build the aircraft it’ll be ready for flight by 2014, and deliverable to customers by 2016.Check out the official site for more images and some Quicktime virtual-tours of the cabin, flight deck and exterior of the aircraft.

RAF receive new Hawk training aircraft

The new Hawk Ts will mean pilots can now train on an aircraft with systems closely compatible with the latest front line jets.The new aircraft builds on the success of its long-serving predecessor, but benefits from significant enhancement to bridge any gap with the latest front line jets entering service, such as the Typhoon.Featuring a 'glass' cockpit and the latest advances in radar, weapons and defensive aids simulation, the Hawk T Mk2 is aimed at providing a seamless transition from flying training to operational squadron.Welcoming the arrival of the first jets at RAF Valley in Wales, Minister for Defence Equipment and Support Quentin Davies said:"Delivery of these aircraft is excellent news for the Royal Air Force and for British industry. Building on the success of the Hawk T Mk1, they will enable our pilots to hone the skills required to fly the latest generation of combat aircraft in a state-of-the-art training environment."In addition to the realistic in-flight training environment, the new Hawk benefits from simpler design and construction, leading to lower acquisition and support costs. Infrastructure to support the new training regime is currently under construction at RAF Valley by the Ascent Flight Services Consortium, which was awarded the £600m contract to deliver all military pilot training on an incremental basis last summer.Air Vice Marshal Baz North, Air Officer Commanding 22 Group, responsible for all RAF training, sang the praises of the aircraft:"The Hawk has long been the backbone of fast jet training but this new advanced version will be far more representative of the new generation of jets that our trainee pilots will go on to fly on operations. It will provide real benefits in enabling pilots to move more rapidly to full combat readiness."Initial deliveries of ten aircraft following formal 'release to service' in April will allow six to be used for development of the full training syllabus, prior to the start of pilot training on the new aircraft in 2011.'Release to service' is a statement that the aircraft is signed off by the RAF as safe to be flown (within specific limitations) by qualified Armed Forces personnel. The 'in service date' is the point in time from which the aircraft will be used for a stated purpose and is set for later this year.The new aircraft are built at the BAE Systems plant at Brough on North Humberside, which employs around 1,800 people. They are then flown to Warton in Lancashire for painting and flight testing prior to delivery to RAF Valley.http://www.raf.mod.uk/news/archive.c...825B6D5466C0EBTango IIIView Public ProfileFind all posts by Tango III#466 Old 3rd July 2009, 14:15Tango III Tango III is online nowRank 5 Registered UserJoin Date: Sep 2006Posts: 3,944Israel hopes Congress will lift F-22 banThe Israel Air Force will review the possibility of purchasing the advanced American F-22 fifth-generation stealth fighter jet if a congressional ban is lifted, enabling it to be sold abroad, defense officials told The Jerusalem Post on Thursday.Referring to recent reports in the US that Congress had asked the Air Force to submit a report on the possibility of exporting the jet to Japan, Israel and other allies, a senior defense official said if this happened, "we will have to consider the option.""This is an advanced fighter jet of superior capabilities," the Defense Ministry official said. "It will depend, though, on the price, availability and time frame."Congress's interest in continuing funding for the F-22 runs counter to US Defense Secretary Robert Gates' decision to stop production of the aircrafts.Israel is already in advanced talks with the Pentagon regarding the possible sale of the Joint Strike Fighter (JSF) - also known as the F-35 - to Israel. Both planes are manufactured by Lockheed Martin, but Israeli defense officials said the F-22 was capable of flying at higher altitudes and could carry more weapons internally."A lot will depend on the outcome of the ongoing talks regarding the JSF," the defense official said. "If the export ban on the F-22 is lifted, things may change."The IAF is also in negotiations with Boeing to purchase at least six additional Apache Longbow attack helicopters in an effort to bolster the air support the IAF is able to provide ground forces.The negotiations are ongoing and sources close to the talks said they would likely be completed by the end of the year. The IAF has yet to decide exactly how many aircraft it would purchase and was waiting to receive a final price offer from Boeing.The IAF is also considering upgrading several of its old "A" model Apache helicopters to the "D" model Longbow version with the above-rotor advanced radar system, which enables the helicopter to share targeting data with other Longbows. According to foreign reports, Israel has 37 "A" model Apaches and 11 Longbows.Three Apache helicopters - including one Longbow version - were lost during the Second Lebanon War. In one case, two Apaches collided in midair. In the other, the Longbow crashed due to a malfunction in the rotor.During Operation Cast Lead, due to the limited scope of the operation, the IAF was able to allocate a squadron of attack helicopters that worked in conjunction with infantry brigades operating on the ground. This organic system, a senior IAF officer said, would not be workable in a larger conflict due to the IAF's limited number of aircraft.

Aeroscraft ML866: the ultimate corporate aircraft

The MQ-9 Reaper, a hunter-killer UAV with long loitering capability, has completed its first operational mission in Iraq. The craft has been used in Afghanistan since 2007, clocking 3,800 hours and attacking 16 targets with 500-pound bombs and Hellfire missiles.The combination of payload capacity and loiter endurance makes the Reaper highly valuable in Iraq, where it is expected to significantly enhance the strike and close-air-support capabilities of air forces. The long loiter capability will be used to establish a "persistent stare" over targets, while its armaments allow it to be drawn into conflict when necessary.Lt. Gen. Gary L North, the Combined Force Air Component commander, says: "The Reaper, as a close-air-support asset, expands beyond the concept of persistent stare to one of persistent strike. If the ground commander wants us to strike an enemy target, we can do that with precision weapons from the Reaper at the exact point where the ground commander wants a desired effect. It's an incredibly powerful and flexible capability for the warfighting commander."The Reaper is fully integrated into existing intelligence, surveillance and reconnaissance architecture employed by the MQ-1 Predator. U.S. Air Force Central's Combined Air and Space Operations Center will plan and execute Reaper sorties in Iraq based on information forwarded from ground commanders.

Finnair's future fleet: flying into the 21st century

To celebrate its 85th anniversary, Finnair has served up a blue-sky vision of what the next 85 years of aviation could hold. Concentrating mainly on potential developments in environmentally friendly technology and lightweight material, the Departure 2093 website lists five aircraft that could grace our sky later this century.
Finnair A600–850 M
The A600-850 M resembles a normal plane that has been squeezed in Photoshop until it takes on the proportions of a dart, complete with needle-thin nose. The plane is described as a “zero-emission supersonic aircraft,” with the speed and efficiency attributed to the super-light nanoceramic material used to construct the fuselage. The design is obviously an extrapolation of the recent trend to use carbon composite materials in aircraft design – however, while they do create lighter and stronger airplanes, a zero-emission vehicle would necessitate drastic changes in the energy used to power aircraft. For the fuel of the future, Finnair nominates three contenders that could make zero-emission planes like the 850 M a reality – solar, biofuel, and hydrogen.
The efficiency of the 850 M is also improved by the partly elastic wings, which adapt to flight speed and weather conditions. Solar panels on the exterior of the plane provide the electricity for passenger amenities, including the very futuristic-sounding 20-inch 3D display.
The description of passenger comfort is predictably Utopic, with intelligent seats monitoring pulse rate, blood pressure and body temperature, as well as giving out free massages. Once again though, the projection has seeds in present-day emerging tech, this time in the field of smart fabrics.
The 126.30m A600-850 M has a wingspan of 60.70m and seats 600-850 passengers. The maximum take-off weight is 310,000kg and the cruising speed is mach 4.5.
Finnair A600-850
Another “zero-emission” aircraft, the A600-850 took its design cues from the ship from The Fantastic Voyage. Like the 850 M, it can fit 600-850 passengers, but is designed for smaller trips. The 81.70m craft has four engines, which can be turned horizontally by 26 degrees and vertically by 55 degrees. The engine configuration is key to the aircraft’s most interesting feature – vertical take off. VTOL is currently a prized feature in military craft, increasing maneoverability and decreasing the amount of space required on the ground. Finnair believes that vertical takeoff will be incorporated into the passenger plane market.
As with the previous hypothetical plane, solar panels cover the outer surface of the 850, and all materials are 100% recyclable. The maximum take-off weight is 322,000kg, the cruising speed is 890km/h, and the maximum cruising level is 13,800m.

Google Earth

Google Earth (GE) was released by Google as a free application in June of 2005. Google describes it briefly as:
The idea is simple. It's a globe that sits inside your PC. You point and zoom to anyplace on the planet that you want to explore. Satellite images and local facts zoom into view. Tap into Google search to show local points of interest and facts. Zoom to a specific address to check out an apartment or hotel. View driving directions and even fly along your route.
Google released the product first for recent versions of Microsoft Windows XP or 2000. The Windows version is no longer beta as of 10-Jan-2006. The beta for Mac was also released on 10-Jan-2006. On June 12, Google released Google Earth 4 Beta simultaneously for Windows, Mac OSX, and Linux. Google Earth 4 was officially released on January 8, 2007.GE is based on a product called "Keyhole" which Google acquired when they purchased the company Keyhole in 2004. . You will need a decent computer with a 3D graphics card, and will find a broadband connection is best. If you have these things, you will find Google Earth one of the most amazing applications you have ever used.

What is Google?

"Googol" is the mathematical term for a 1 followed by 100 zeros. The term was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, "Mathematics and the Imagination" by Kasner and James Newman. Google's play on the term reflects the company's mission to organize the immense amount of information available on the web.

Google Company Overview

Google's mission is to organize the world's information and make it universally accessible and useful.
As a first step to fulfilling that mission, Google's founders Larry Page and Sergey Brin developed a new approach to online search that took root in a Stanford University dorm room and quickly spread to information seekers around the globe. Google is now widely recognized as the world's largest search engine -- an easy-to-use free service that usually returns relevant results in a fraction of a second.
When you visit http://www.google.com/ or one of the dozens of other Google domains, you'll be able to find information in many different languages; check stock quotes, maps, and news headlines; lookup phonebook listings for every city in the United States; search billions of images and peruse the world's largest archive of Usenet messages -- more than 1 billion posts dating back to 1981.
We also provide ways to access all this information without making a special trip to the Google homepage. The Google Toolbar enables you to conduct a Google search from anywhere on the web. And for those times when you're away from your PC altogether, Google can be used from a number of wireless platforms including WAP and i-mode phones.
Google's utility and ease of use have made it one of the world's best known brands almost entirely through word of mouth from satisfied users. As a business, Google generates revenue by providing advertisers with the opportunity to deliver measurable, cost-effective online advertising that is relevant to the information displayed on any given page. This makes the advertising useful to you as well as to the advertiser placing it. We believe you should know when someone has paid to put a message in front of you, so we always distinguish ads from the search results or other content on a page. We don't sell placement in the search results themselves, or allow people to pay for a higher ranking there.
Thousands of advertisers use our Google AdWords program to promote their products and services on the web with targeted advertising, and we believe AdWords is the largest program of its kind. In addition, thousands of web site managers take advantage of our Google AdSense program to deliver ads relevant to the content on their sites, improving their ability to generate revenue and enhancing the experience for their users.

Gardening

Gardening has to do with the production of food and seeds. Starts with Soil. Where does it come from and how do you keep the soil so it will provide the food plants need to grow? Seeds. Where do seeds come from (yes, they come from plants, but how do farmers and gardeners get all the many seeds they need?). But it also has to do with the management of soil and water. A very important issue that will be in your studies throughout the Expedition. Water, who owns it and how does it get shared. You have to have water to grow food to feed people. Beyond that is the magic and the mytholody of gardening. Many Native American Tribes know the art of Weather Making. We'll study weather in the Global-Garden Expedition. Gardening also has to do with Sustainability. Garden Sustainability (which means making a garden that will be there next year), Community Sustainability, Regional Sustainability, each is conected to the others. The ability to grow food has a lot to do with a community or tribes sustainability. We will study Sustainable Communities and their gardens as we journey through the Global-Garden Expedition.

Real Estate

The real estate sector plays a significant role in the country's economy. The real estate sector is second only to agriculture in terms of employment generation and contributes heavily towards the gross domestic product (GDP). Almost five per cent of the country's GDP is contributed to by the housing sector. In the next five years, this contribution to the GDP is expected to rise to 6 per cent. According to industry players, housing accounts for 4.5 per cent of gross domestic product (GDP) with urban housing accounting for 3.13 per cent.
According to Jones Lang LaSalle CEO, Colin Dyer, faster economic growth in Brazil, Russia, India and China (BRIC) could result in the property markets of those nations recovering at a faster rate than the UK and US real estate markets. It has also been suggested that India's property sector could begin to improve from late 2009 and may attract up to US$ 12.11 billion in real estate investment over a five-year period.
Moreover, the real estate sector is also responsible for the development of over 250 ancillary industries such as cement, steel, paints etc. A study by rating agency ICRA shows that the construction industry ranks 3rd among the 14 major sectors in terms of direct, indirect and induced effects in all sectors of the economy. A unit increase in expenditure in this sector has a multiplier effect and the capacity to generate income as high as five times.
Residex, an index planned to benchmark the housing sector and expected to serve as an indicator of property prices, the housing start-up index (HSUI) planned by the Reserve Bank (RBI) of India aims to indicate the volume of construction taking place in a particular location. The RBI also expects to publish the data by March 2010 for every quarter. HSUI would also serve as a lead indicator of the economy's growth as more houses would require more input materials like cement and steel, labour and credit demand.
This index would be useful for developers as it would help know areas of oversupply. They can hence refrain from construction activity in those areas. In case of an oversupply in a particular location, consumers before investing would wait till prices fall.

Electrical Generator

An electrical generator is a device that converts mechanical energy to electrical energy, generally using electromagnetic induction. The source of mechanical energy may be a reciprocating or turbine steam engine, water falling through a turbine or waterwheel, an internal combustion engine, a wind turbine, a hand crank, or any other source of mechanical energy.Early 20th century Alternator made in Budapest, Hungary, in the power generating hall of a hydroelectric station.Historic developmentsBefore the connection between magnetism and electricity was discovered, generators used electrostatic principles. The Wimshurst machine used electrostatic induction or "influence". The Van de Graaff generator uses either of two mechanisms:* Charge transferred from a high-voltage electrode * Charge created by the triboelectric effect using the separation of two insulators (the belt leaving the lower pulley)Electrostatic generators are used for scientific experiments requiring high voltages. Because of the difficulty of insulating machines producing very high voltages, electrostatic generators are made only with low power ratings and are never used for generation of commercially-significant quantities of electric power.FaradayPortable generator side view showing gasoline engine.In 1831-1832 Michael Faraday discovered that a potential difference is generated between the ends of an electrical conductor that moves perpendicular to a magnetic field. He also built the first electromagnetic generator called the 'Faraday disc', a type of homopolar generator, using a copper disc rotating between the poles of a horseshoe magnet. It produced a small DC voltage, and large amounts of current.DynamoThe dynamo was the first electrical generator capable of delivering power for industry. The dynamo uses electromagnetic principles to convert mechanical rotation into an alternating electric current. A dynamo machine consists of a stationary structure which generates a strong magnetic field, and a set of rotating windings which turn within that field. On small machines the magnetic field may be provided by a permanent magnet; larger machines have the magnetic field created by electromagnets.The first dynamo based on Faraday's principles was built in 1832 by Hippolyte Pixii, a French instrument maker. It used a permanent magnet which was rotated by a crank. The spinning magnet was positioned so that its north and south poles passed by a piece of iron wrapped with wire. Pixii found that the spinning magnet produced a pulse of current in the wire each time a pole passed the coil. Furthermore, the north and south poles of the magnet induced currents in opposite directions. By adding a commutator, Pixii was able to convert the alternating current to direct current.Unlike the Faraday disc, many turns of wire connected in series can be used in the moving windings of a dynamo. This allows the terminal voltage of the machine to be higher than a disc can produce, so that electrical energy can be delivered at a convenient voltage.The relationship between mechanical rotation and electric current in a dynamo is reversible; the principles of the electric motor were discovered when it was found that one dynamo could cause a second interconnected dynamo to rotate if current was fed through it.Jedlik's dynamoÁnyos Jedlik's single pole electric starter (dynamo) (1861)In 1827, Anyos Jedlik started experimenting with electromagnetic rotating devices which he called electromagnetic self-rotors. In the prototype of the single-pole electric starter (finished between 1852 and 1854) both the stationary and the revolving parts were electromagnetic. He formulated the concept of the dynamo at least 6 years before Siemens and Wheatstone. In essence the concept is that instead of permanent magnets, two electromagnets opposite to each other induce the magnetic field around the rotor.Gramme dynamoBoth of these designs suffered from a similar problem: they induced "spikes" of current followed by none at all. Antonio Pacinotti, an Italian scientist, fixed this by replacing the spinning coil with a toroidal one, which he created by wrapping an iron ring. This meant that some part of the coil was continually passing by the magnets, smoothing out the current. Zénobe Gramme reinvented this design a few years later when designing the first commercial power plants, which operated in Paris in the 1870s. His design is now known as the Gramme dynamo. Various versions and improvements have been made since then, but the basic concept of a spinning endless loop of wire remains at the heart of all modern dynamos.ConceptsThe generator moves an electric current, but does not create electric charge, which is already present in the conductive wire of its windings. It is somewhat analogous to a water pump, which creates a flow of water but does not create the water itself.Other types of electrical generator exist, based on other electrical phenomena such as piezoelectricity, and magnetohydrodynamics. The construction of a dynamo is similar to that of an electric motor, and all common types of dynamos could work as motors.Equivalent circuitEquivalent circuit of generator and load.G = generatorVG=generator open-circuit voltageRG=generator internal resistanceVL=generator on-load voltageRL=load resistanceThe equivalent circuit of a generator and load is shown in the diagram to the right. To determine the generator's VG and RG parameters, follow this procedure: -* Before starting the generator, measure the resistance across its terminals using an ohmmeter. This is its DC internal resistance RGDC. * Start the generator. Before connecting the load RL, measure the voltage across the generator's terminals. This is the open-circuit voltage VG. * Connect the load as shown in the diagram, and measure the voltage across it with the generator running. This is the on-load voltage VL. * Measure the load resistance RL, if you don't already know it. * Calculate the generator's AC internal resistance RGAC from the following formula:R_{GAC} = {R_L} \left( {{{V_G}\over{V_L}}-1} \right)Note 1: The AC internal resistance of the generator when running is generally slightly higher than its DC resistance when idle. The above procedure allows you to measure both values. For rough calculations, you can omit the measurement of RGAC and assume that RGAC and RGDC are equal.Note 2: If the generator is an AC type (distinctly not a dynamo), use an AC voltmeter for the voltage measurements.Maximum powerThe maximum power theorem applies to generators as it does to any source of electrical energy. This theorem states that the maximum power can be obtained from the generator by making the resistance of the load equal to that of the generator. However, under this condition the power transfer efficiency is only 50%, which means that half the power generated is wasted as heat inside the generator. For this reason, practical generators are not usually designed to operate at maximum power output, but at a lower power output where efficiency is greater.Low-powerEarly motor vehicles tended to use DC generators with electromechanical regulators. These were not particularly reliable or efficient and have now been replaced by alternators with built-in rectifier circuits. These power the electrical systems on the vehicle and recharge the battery after starting. Rated output will typically be in the range 50-100 A at 12 V, depending on the designed electrical load within the vehicle - some cars now have electrically-powered steering assistance and air conditioning, which places a high load on the electrical system. Commercial vehicles are more likely to use 24 V to give sufficient power at the starter motor to turn over a large diesel engine without the requirement for unreasonably thick cabling. Vehicle alternators usually do not use permanent magnets; they can achieve efficiencies of up to 90% over a wide speed range by control of the field voltage. Motorcycle alternators often use permanent magnet stators made with rare earth magnets, since they can be made smaller and lighter than other types.Some of the smallest generators commonly found are used to power bicycle lights. These tend to be 0.5 A permanent-magnet alternators, supplying 3-6 W at 6 V or 12 V. Being powered by the rider, efficiency is at a premium, so these may incorporate rare-earth magnets and be designed and manufactured with great precision. Nevertheless, the maximum efficiency is only around 60% for the best of these generators - 40% is more typical - due to the use of permanent magnets. A battery would be required in order to use a controllable electromagnetic field instead, and this is unacceptable due to its weight and bulk.Aircraft have also switched from DC generators to alternators; these are typically powered by a takeoff from an engine.Sailing yachts may use a water or wind powered generator to trickle-charge the batteries. A small propeller, wind turbine or impeller is connected to a low-power alternator and rectifier to supply currents of up to 12 A at typical cruising speeds.Engine-generatorEngine - generator of the radio station (Dubendorf museum of the military aviation). The generator worked only when sending the radio signal (the receiver could operate on the battery power)Hand-driven electric generator of the radio station (Dubendorf museum of the military aviation)An engine-generator is the combination of an electrical generator and an engine mounted together to form a single piece of equipment. This combination is also called an engine-generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator.In addition to the engine and generator, engine-generators generally include a fuel tank, an engine speed regulator and a generator voltage regulator. Many units are equipped with a battery and electric starter. Standby power generating units often include an automatic starting system and a transfer switch to disconnect the load from the utility power source and connect it to the generator.Engine-generators produce alternating current power that is used as a substitute for the power that might otherwise be purchased from a utility power station. The generator voltage (volts), frequency (Hz) and power (watts) ratings are selected to suit the load that will be connected. Both single-phase and three-phase models are available. There are only a few portable three-phase generator models available in the US. Most of the portable units available are single phase power only and most of the three-phase generators manufactured are large industrial type generators.Engine-generators are available in a wide range of power ratings. These include small, hand-portable units that can supply several hundred watts of power, hand-cart mounted units, as pictured above, that can supply several thousand watts and stationary or trailer-mounted units that can supply over a million watts. The smaller units tend to use gasoline (petrol) as a fuel, and the larger ones have various fuel types, including diesel, natural gas and propane (liquid or gas).When using engine-generators, you must be aware of the quality of the electrical wave it outputs. This is particularly important when running sensitive electronic equipment. A power conditioner can take the square waves generated by many engine-generators and smooth it out by running it through a battery in the middle of the circuit. Using an inverter rather than a generator may also produce clean sinusoidal waves. There are several quiet running inverters available that produce clean sinusoidal wave power suitable for use with computers and other sensitive electronics, however some low cost inverters do not produce clean sinusoidal waves and may damage certain electronic charging equipment.Engine-generators are often used to supply electrical power in places where utility power is not available and in situations where power is needed only temporarily. Small generators are sometimes used to supply power tools at construction sites. Trailer-mounted generators supply power for lighting, amusement rides etc. for traveling carnivals.Standby power generators are permanently installed and kept ready to supply power to critical loads during temporary interruptions of the utility power supply. Hospitals, communications service installations, sewage pumping stations and many other important facilities are equipped with standby power generators.Small and medium generators are especially popular in third world countries to supplement grid power, which is often unreliable. Trailer-mounted generators can be towed to disaster areas where grid power has been temporarily disrupted.The generator can also be driven by the human muscle power (for instance, in the field radio station equipment).Mid-size stationary engine-generatorThe mid-size stationary engine-generator pictured here is a 100 kVA set which produces 415 V at around 110 A per phase. It's powered by a 6.7 litre turbocharged Perkins Phaser 1000 Series engine, and consumes approximately 27 litres of fuel an hour, on a 400 litre tank. Stationary generators used in the US are used in size up to 2800 kW. These diesel engines are run in the UK on red diesel and rotate at 1500 rpm. This produces power at 50 Hz, which is the frequency used in the UK. In areas where the power frequency is 60 Hz (United States), generators rotate at 1800 rpm or another even multiple of 60. Diesel engine-generator sets operated at their best efficiency point can produce between 3 and 4 kilowatthours of electrical energy for each litre of diesel fuel consumed, with lower efficiency at part load .

Accountancy

Finance is a field that studies and addresses the ways in which individuals, businesses, and organizations raise, allocate, and use monetary resources over time, taking into account the risks entailed in their projects. The term finance may thus incorporate any of the following:The study of money and other assets;The management and control of those assets;Profiling and managing project risks;The science of managing money;As a verb, "to finance" is to provide funds for business or for an individual's large purchases (car, home, etc.).The activity of finance is the application of a set of techniques that individuals and organizations (entities) use to manage their financial affairs, particularly the differences between income and expenditure and the risks of their investments.An entity whose income exceeds its expenditure can lend or invest the excess income. On the other hand, an entity whose income is less than its expenditure can raise capital by borrowing or selling equity claims, decreasing its expenses, or increasing its income. The lender can find a borrower, a financial intermediary, such as a bank or buy notes or bonds in the bond market. The lender receives interest, the borrower pays a higher interest than the lender receives, and the financial intermediary pockets the difference.A bank aggregates the activities of many borrowers and lenders. A bank accepts deposits from lenders, on which it pays the interest. The bank then lends these deposits to borrowers. Banks allow borrowers and lenders, of different sizes, to coordinate their activity. Banks are thus compensators of money flows in space.A specific example of corporate finance is the sale of stock by a company to institutional investors like investment banks, who in turn generally sell it to the public. The stock gives whoever owns it part ownership in that company. If you buy one share of XYZ Inc, and they have 100 shares outstanding (held by investors), you are 1/100 owner of that company. Of course, in return for the stock, the company receives cash, which it uses to expand its business in a process called "equity financing". Equity financing mixed with the sale of bonds (or any other debt financing) is called the company's capital structure.Finance is used by individuals (personal finance), by governments (public finance), by businesses (corporate finance), etc., as well as by a wide variety of organizations including schools and non-profit organizations. In general, the goals of each of the above activities are achieved through the use of appropriate financial instruments, with consideration to their institutional setting.Finance is one of the most important aspects of business management. Without proper financial planning a new enterprise is unlikely to be successful. Managing money (a liquid asset) is essential to ensure a secure future, both for the individual and an organization.

World Economy

The world economy can be evaluated in various ways, depending on the model used, and this valuation can then be represented in various ways (for example, in 2006 US dollars). It is inseparable from the geography and ecology of Earth, and is therefore somewhat of a misnomer, since, while definitions and representations of the "world economy" vary widely, they must at a minimum exclude any consideration of resources or value based outside of the Earth. For example, while attempts could be made to calculate the value of currently unexploited mining opportunities in unclaimed territory in Antarctica, the same opportunities on Mars would not be considered a part of the world economy – even if currently exploited in some way – and could be considered of latent value only in the same way as uncreated intellectual property, such as a previously unconceived invention. Beyond the minimum standard of concerning value in production, use, and exchange on the planet Earth, definitions, representations, models, and valuations of the world economy vary widely.It is common to limit questions of the world economy exclusively to human economic activity, and the world economy is typically judged in monetary terms, even in cases in which there is no efficient market to help valuate certain goods or services, or in cases in which a lack of independent research or government cooperation makes establishing figures difficult. Typical examples are illegal drugs and prostitution, which by any standard are a part of the world economy, but for which there is by definition no legal market of any kind.However, even in cases in which there is a clear and efficient market to establish a monetary value, economists do not typically use the current or official exchange rate to translate the monetary units of this market into a single unit for the world economy, since exchange rates typically do not closely reflect world-wide value, for example in cases where the volume or price of transactions is closely regulated by the government. Rather, market valuations in a local currency are typically translated to a single monetary unit using the idea of purchasing power. This is the method used below, which is used for estimating worldwide economic activity in terms of real US dollars. However, the world economy can be evaluated and expressed in many more ways. It is unclear, for example, how many of the world's 6.5 billion people have most of their economic activity reflected in these valuations.

Donald Trump real estate properties

Recently, Donald Trump rejected a $90 million offer on his Palm Beach estate Maison de l'Amitie. His asking price is $125 million and the offer was made by Steve Schwarzman, who just led the IPO for Blackstone.It seems as though Donald Trump is looking for the publicity in this Real Estate venture, and therefore, the timing is not as important as the money. In fact, some say that his target is selling the Real Estate for not less than $100 million and he's willing to wait to get it. In fact, selling a Real Estate property for more than $100 million, will get him worldwide press and coverage, which is what the Trump brand is really after...As WSJ.com informs:"Mr. Schwarzman, Blackstone’s $7 billion man, made a $90 million offer in recent months for Maison de l’Amitie , the Palm Beach estate that’s being sold by Donald Trump, according to people familiar with the offer. Yet Mr. Trump rejected the bid, saying the price was too low, these people said. The house is listed for $125 million. People close to the situation say Mr. Trump rejected the offer quickly, since he wants to get at least $100 million for the place.“He wants to hit the magic number of $100 million,”says one Palm Beach realtor.“Getting the price is more important to him than selling it quickly.”Mr. Trump, in a rare moment of media silence, declined comment. A spokesman for Mr. Schwarzman couldn’t be reached for comment this afternoon."
