MIT builds solar-powered race car that runs all day

A group of researchers at MIT have developed an out-of-the-ordinary new race car, one that isnt dependent on gasoline. Thats right, the team has built a car that runs on solar power .

The car, dubbed Eleanor , can reportedly maintain a cruising speed of 55 miles-per-hour and run all day — if the sun is shining, according to MIT. To get that kind of power from sunlight, researchers have designed the car with six square meters of monocrystalline silicon solar cells and an improved electronic systems.

Newark, DE Becomes First US City to Use Cars for Grid Power

V2G technology works based on the theory that the growing use of unreliable renewable energy sources requires energy storage to smooth power output fluctuations. An electric vehicle can use wind power, for example, to charge at night. The grid operator can then use energy stored in the batteries while the vehicle is plugged in to stabilize the grid.

Different Clean Air Technologies

Wind is a renewable energy source that emits no pollution. It is the fastest-growing “green” energy in the U.S. and provides light to the Statue of Liberty. Wind farms—clusters of huge windmills—produce electricity by using the motion of their blades to spin a shaft connected to a generator. Experts estimate that the electricity created in 2006 by America’s wind farms will displace some 15 million tons of carbon dioxide. Over five million acres of forest would be needed to absorb that much CO2. Some people oppose wind farms because they occupy large tracts of land and can sometimes harm birds, but most agree that their environmental costs are much lower than those of fossil fuels.
