I found a great place to replace all kinds of batteries. Anything from laptops to camcorders, cordless phones etc. the site has a cool name for battery replacement

A disc-shaped solar panel attached underneath powers the propeller when struck by a ground-based laser. Great idea can I get one for Xmas 07…

I’m sure someone is dreaming how to make a weapon out of this.
Thats the bad new, Good news Somebody is thinking about transmitted power. How few people have any Imagination. No I’m not going to spell it out for you.

Yeah,

This needs to be filed all right. How about under: Things-to-waste-research-funds-on-while-fooling-around-with-high- powered-lasers-in-a-pathetic-attempt-to-justify-your-silly-idea?

Of course, electric R/C planes can already stay up for an hour or so — the five minute figure is only because this plane has a small battery and an inefficient shape.

You’d also need some expensive infrastructure on the ground — an expensive and power-heavy laser and tracking system, and the plane cannot leave the immediate area.

Personally, I’d say the most likely power source for this sort of thing in the near future is a fuel cell, and for now, if you need to stay up more than an hour, an IC engine of some sort is still what’s needed.
