Can I buy an electric-powered airplane?

Many companies will display electric-powered airplanes at Oshkosh this year, but a practical airplane you can purchase has proven to be a challenge.
The Experimental Aircraft Association has asked the FAA to allow light sport and ultralight aircraft to use electric propulsion, so there is a lot of interest.
Electric Aircraft’s ElectraFlyer airplane has flown several times with an 18-horsepower electric motor, and the company plans to build a 40-hp version.
Sonex Aircraft says it has a more powerful motor and a controller of its own design that feeds electricity from the lithium polymer battery to the motor. This is the key to making electric airplanes feasible, a Sonex spokesman said. The aircraft has not yet flown. In the video you will hear of an 800-cell battery, but Sonex officials say they now prefer a battery of less than 80 cells.
Pipistrel says it has a two-seat electric glider flying, which was made from its gas-powered Taurus model. However, electric-powered gliders are not entirely new. Lange Aviation’s Antares 20E is already on the market.
So where’s the hybrid airplane with both a gas engine and electric motor (currently too heavy for small aircraft)? Keep watching.

Hello fu679s,
Electric airplanes are unfortunately not yet so easily available. Like at the beginnings of the oil-age, road transport will be before aviation and gets this technology first. Whether it will be used in one form or the other depends largely on battery/storage technology. But recent developments are promising.
BTW, Bertrand Piccar, adventurer, psychologist and pilot plans to circle the earth with a solar powered aircraft. His project has reached an advanced state and you can monitor the progress here:
