My Gadjet

The PlayStation Portable (officially abbreviated PSP) is a handheld game console manufactured and marketed by Sony Computer Entertainment. Development of the console was first announced during 2003, and it was unveiled on May 11, 2004 at a Sony press conference before 2004.

The PlayStation Portable is the first handheld video game console to use an optical disc format, Universal Media Disc (UMD), as its primary storage media. Other distinguishing features of the console include its large viewing screen, robust multi-media capabilities, and connectivity with the PlayStation 3, other PSPs, and the Internet.

Manufacturer : Sony Computer Entertainment
Product family : PlayStation
Type : Handheld game console
Generation : Seventh generation era
Media : UMD
CPU : MIPS R4000-based ; clocked from 1 to 333 MHz
Storage capacity : Memory Stick Duo and Memory Stick PRO Duo
Connectivity : Wi-Fi (802.11b), IrDA, USB

At 2007, Sony announced that a new version of the PSP would be released in September 2007, for all regions. The redesigned PSP is 33% lighter and 19% thinner than the original PSP. The redesign also features composite TV output, supports charging viaUSB, double the onboard RAM (32 MB to 64 MB), and has a brighter screen. It also caches UMD data in memory to decrease game loading times. The WLAN switch has been moved to the top where the old IR receiver was to avoid accidental switching, and the speaker vents that were at the bottom and underside of the original PSP have been moved to the top of this new model.

Renewable Energy

Renewable energy is energy generated from natural resources such as sunlight, wind, rain, tides and geothermal heat. This energy are renewable (naturally replenished). In 2006, about 18% of global final energy consumption came from renewable, with 13% coming from traditional biomass, such as wood-burning.

Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation), followed by solar hot water or heating, which contributed 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption.

Wind power is growing at the rate of 30 percent annually, with a worldwide installed capacity of over 100 GW, and is widely used in several European countries and the United States. The manufacturing output of the photovoltaic industry reached more than 2,000 MW in 2006, and photovoltaic (PV) power stations are particularly popular in Germany and Spain.

Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 MW SEGS power plant in the Mojave Desert. The world's largest geothermal power installation is The Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18 percent of the country's automotive fuel. Ethanol fuel is also widely available in the USA.

Hybrid Car

A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle. The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors.

Power sources include:
• On-board or out-board rechargeable energy storage system (RESS)
• Gasoline or Diesel fuel
• Hydrogen
• Compressed air
• Human powered e.g. pedaling or rowing
• Wind
• Compressed or liquefied natural gas
• Solar
• Coal, wood or other solid combustibles

Fuel consumption and emissions reductions

The hybrid vehicle typically achieves greater fuel economy and lower emissions than conventional internal combustion engine vehicles (ICEVs), resulting in fewer emissions being generated. These savings are primarily achieved by three elements of a typical hybrid design:

1. relying on both the gasoline (or diesel engine) and the electric motors for peak power needs resulting in a smaller gasoline or diesel engine sized more for average usage rather than peak power usage
2. having significant battery storage capacity to store and reuse recaptured energy, especially in stop-and-go traffic.
3. recapturing significant amounts of energy normally wasted during braking etc. (regenerative braking) This is a mechanism that reduces vehicle speed by converting some of its kinetic energy into another useful form of energy, dependent upon the power rating of the motor/generator
4. shutting down the gasoline or diesel engine during traffic stops or while coasting or other idle periods;
5. improving aerodynamics ; (part of the reason that SUVs get such bad gas mileage is the drag on the car. A box shaped car or truck has to exert more force to move through the air causing more stress on the engine making it work harder). Improving the shape and aerodynamics of a car is a good way to help better the gas mileage and also improve handling at the same time.

The Best Football Club

Manchester United Football Club is an English football club, based at Old Trafford in Trafford, Greater Manchester, and is one of the most popular football clubs in the world, with over 330 million supporters worldwide. This is almost 5% of the world's population. The club was a founding member of the Premier League in 1992, and has played in the top division of English football since 1938, with the exception of the 1974–75 season. Average attendances at the club have been higher than any other team in English football for all but six seasons since 1964–65.

Manchester United are the reigning English, European, and World Champions having won the 2007–08 Premier League, the 2007–08 UEFA Champions League, and the 2008 FIFA Club World Cup. The club is the second most successful in the history of English football and by far the most successful of recent times, having won 21 major honours since the start of Alex Ferguson's reign as manager in November 1986. In 1968, they became the first English club to win the European Cup, beating Benfica 4–1. They won a second European Cup as part of a Treble in 1999, before winning their third in 2008, 40 years almost to the day after their first. The club also holds the record for the most FA Cup titles with 11.

Since the late 1990s, the club has been one of the richest in the world with the highest revenue of any football club, and is currently ranked as the richest and most valuable club in any sport, with an estimated value of £897 million (€1.333 billion / $1.8 billion) as of September 2008. Manchester United was a founding member of the now defunct G-14 group of Europe's leading football clubs, and its replacement, the European Club Association.
