I hope I’m long dead before electric cars become acceptable!
..............
meaningful volume won’t start for another 5-6 years or so.
another big up and comer is natural gas trucks and vehicles. Their growth rate is slower than electric cars.
if another type vehicle came along imho that would be fine too.
I’m mostly interested in cutting the demand and there for the price of gasoline.
I don’t see that happening in the next decade.
These cars are cool. It is nice that someone made an effective vehicle that can be relatively reliable for those with the funds and the time to recharge every night. The are a long way from replacing or even competing with a vehicle that gets 350+ miles to a tank and can be refueled and on it’s way again in ten minutes or less.

Researchers developing cheap, better-performing lithium-ion batteries

Researchers at the USC Viterbi School of Engineering have improved the performance and capacity of lithium batteries by developing better-performing, cheaper materials for use in anodes and cathodes (negative and positive electrodes, respectively).
The USC Viterbi team developed a cost-effective (and therefore commercially viable) silicon anode with a stable capacity above 1100 mAh/g for extended 600 cycles, making their anode nearly three times more powerful and longer lasting than a typical commercial anode.
“Our method of producing nanoporous silicon anodes is low-cost and scalable for mass production in industrial manufacturing, which makes silicon a promising anode material for the next generation of lithium-ion batteries,” said Zhou. “We believe it is the most promising approach to applying silicon anodes in lithium-ion batteries to improve capacity and performance.”
If electric vehicles ever supply more than a few percent of ge vehicles on the road, they’ll be powered by fuel cells or capacitors, not by batteries.

From that article:Researchers developing cheap, better-performing lithium-ion batteries
http://phys.org/news/2014-03-cheap-better-performing-lithium-ion-batteries.html
The USC Viterbi team developed a cost-effective (and therefore commercially viable) silicon anode with a stable capacity above 1100 mAh/g for extended 600 cycles, making their anode nearly three times more powerful and longer lasting than a typical commercial anode.
So: 1100mAh/g * 1.2V * 1A/1000mA * 1W/1VA * 1kW/1000W * 1000g/1kg = 1.32 kWh/kg.
And gasoline: 33.7kWh/gal * 1gal/3.785l * 1l/.75kg = 11.9 kWh/kg
It's not even close.
