There is an interesting article in the latest Scientific American
describing a GM/Hughs/AeroVironment solar powered car that won the race
across Australia.

They used GaAs solar cells to get another 20 or 30% more energy relative
to silicon. Anybody know what the rough costs are?  Where does amorphous
silicon fit on the cost/efficiency chart?

The article also discusses batteries a lot. Silver-zinc has 4 times the
energy density of lead-acid. Anybody know how NiCads compare with sealed
lead gell cells in energy density (or price)?
