Electric cars may not be solution to all world problems

Joe Rosenfels

lithium batteries & traffic flow

good point Pete.

My previous post from ‘Carmakers tout green motors in Geneva’

Couple points about lithium batteries.

1. Only 4 countries in the world have lithium.

2. GM Volt, electric plug in car which uses lithium batteries, had very inconsistent battery life ie 2 months to 5 years!

3. Electric cars sound great but Northern Hemisphere countries with cold climates are not suited to batteries. Try starting an electric car in 30 below and the performace of the battery is reduced by 50%.

Traffic Flow:

If we could slow down the traffic but not make it stop would save more than 50% of the energy (electric, ethnaol, etc). In Sydney I stop for every 8 stop lights out of 10....

Cheers
