WHAT IS SOLARENERGY?
Solar energy is the energy received by the earth from the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible.
APPLICATIONS:
1.SOLAR VEHICLE
2.ELECTRIC BOAT
3.SOLAR BALOON
4.SOLAR-CHARGED VEHICLE
In 1974, the unmanned AstroFlight Sunrise plane made the first solar flight. On 29 April 1979, the Solar Riser made the first flight in a solar powered, fully controlled, man carrying flying machine, reaching an altitude of 40 feet (12 m). In 1980, the Gossamer Penguin made the first piloted flights powered solely by photo voltaics
A solar balloon is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward buoyancy force, much like an artificially heated hot air balloon. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface-area to payload-weight ratio is relatively high.
Conclusion:
SOLAR TRANSPORTATION IS ECONOMICAL,POLLUTION FREE,NATURAL,HUMAN FRIENDLY WAY OF TRANSPORTATION……..
