Try Solar Energy On Planes?

Tue Feb 13, 2001 12:40 am

How much energy can solar power produce?
Lets have a crazy idea out here, can we fly a plane with solar energy at day time, and use fuel in the dark?
Or, if we use the solar energy with fuel, wouldn't that save power?? Also it can change the energy source for the engines!!
If that works, wouldn't be energy saving and eviromental friendly?

You couldn't fit enough solar cells on an aircraft to get it off the ground. Cost would also be a bummer.

so a plane needs to carry both solar power cells and fuel together?? this increase the weight and thus decrease the range of the aircraft!

How to change the energy source from solar to fuel or vice versa is a big problem too, the engine would stop and the plane would probably stall.

but i think developing new energy souce is really need before we used up all the fuel for aircrafts!
let's be environmental friendly!!!

From what I understand -- and I'm sure y'all will correct me if I'm wrong -- electrical power on an aircraft is generated as a by-product of or in the same process as the thrust from the engines. It's not like aircraft take power from California's grid... so what would the motivation be for solar?

You'd save power that would be generated anyway, and couldn't be reused...

I sort of get what you mean. But is there any new technologies that can produce something to put on a plane to change the solar energy to kinetic energy for the engines to move? Need to be light enough, I suppose.
