Electric Vehicle

Here are two sites I was reading:

www.metallicpower.com
www.electric-fuel.com

Both these companies are developing zinc-air fuel cells, which have 7
times the energy density of lead-acid batteries.

Could this technology be practical for powering an electric
airplane/helicopter/gyroplane?

Jim Dunn is leading an effort to develop a fuel-cell powered airplane.
I was involved in the project up until about a year ago. I don't what the
current status is.

There's an electric self-launch glider out there now.

Not sure what kind of batteries it uses.

weight 40 kg
energy 1.4 kWh

For reasons of cost and availability, NiCd technology was
chosen for the battery. NiCd offers the highest specific
performance at moderate costs and is available for everyone.
The temperature characteristic and rapid-charge capability
allow high start frequency without overheating of the battery.

I want one.
