"Electric Ferrari"

A proof-of-concept that electric cars can be: Powerful, practical, and sexy.

Catch, is it's $90,000 retail.



Way it gets the range is by using a massive array of laptop batteries. (Lithium Ion)

The Prius and the old EV1 use NiMH (Nickel Metal Hydride Batteries)
Don't quite offer the punch of Lithium Ion.

Past Lithium, you have NanoLithium Batteries,
and Nano UltraCapacitors being developed that plan to shatter existing limits.
Allowing for recharge speeds in minutes, with driving ranges well above those of conventional cars.

Inbetween there, you have plugin hybrids electric vehicles. (PHEV)
Which are essentially electric cars, with a backup gasoline generator for extended range.
Like the upcoming GM Volt.

If you want to really get into some gritty details on the Tesla for various stuff:
Check their whitepaper.

All the while, the generating capacity of cars nationwide is 20x larger than our electricity grid.
(About 29,000GWh versus 2,700GWh)

By borrowing some of that capacity, wind and solar could become just as reliable as coal or natural gas.
And help stabalize the electricity grid, saving billions in yearly generation costs.

Tesla goes over pretty well Why Electric is the superior choice for the future.

Starting off with, that it's 3x more energy effecient than fuel cell cars.
Biomass in an electric power plant, or diesel generator is 2x as effecient than BioFuels.

But I think the best example was that it takes about 32x less land to do solar than ethanol.

Even the very best farm crops are only 1-2% effecient at converting sunlight into energy.
Solar electricity can be anywhere between 10-35% effecient. (And double or triple that in the future)

Why are we wasting our time with Ethanol and Hydrogen?

Bring on the Electricity :)
