SO MUCH FOR VOLT’S BATTERIES COWERING, AMIRITE?

Err, more efficient electric motors? you mean more that current-95%-efficient ones? Why bother? There are some advances in getting them even more lighter ot cheaper, but they are so good on that front already, that it wont change how much they beat life out ice-powertrain (and on race-track it only takes about half as much as ev-power to compete with ice-power – flat torque curve sends its condolences to clutch-gears set)

And if you think you can in couple sentences “give-out” any significant research that isnt duplicated independly in 30 other places already – you’re right about worrying about your job.

And for god-sakes, why everybody bitches about range? there are so many interesting alternatives for extending range:

Everybody is focused on batteries, capacitors and weight used for electric vehicles. There is still a lot to be said about electric motor efficiency and motor drive efficiency. Is there anyone out there willing to speak on advances in those technologies. If you are please make it short and sweet as to not give out all our secrets to our competitive nations. We still need our jobs here.

Bob’s right, I think, about including engine weight with gasoline weight when figuring energy density. That makes the practical gasoline available energy density much less.

Energy storage advances again…

Who cares about GM…they will be bankrupt by 2011.

With regards to the energy density, it seems to me that the weight of the motor needs to be included as well, since the energy in gasoline can’t be harnessed without it. You could ignore that factor if a gasoline motor weighed the same as an electric motor, but (er, am I wrong here?) an electric motor should weigh a fair bit less. Which makes the overall power density of electric look somewhat better.

“Might be years…”

Given we have yet to even see a prototype of EEStor’s technology, I would be very surprised if it reaches a production model in under a decade.

As Zenn Motors has exclusive rights to EEStor’s technology for all vehicles up to 1400kg weight and Zenn is the only publicly traded company or the three involved in the development of the EESU it’s pretty obvious what will happen: Zenn will get bought out by one of the major car companies and incorporated into their electric vehicle division. Unfortunately, then the EESU will disappear down the black hole of their R&D department as they try to figure out how to incorporate it into their product lines. Might be years before you see any cars built with this technology.

I would imagine that the Camry is in the 1400kg arena once the engine, gas tank, ect is removed.

I am under the impression that eestor will not be sold for hybrids. If they keep to that, we will quickly see cars flip to electric, new filling stations, and VERY fast economy, assuming that detroit decides to bring back manufactuering to America.
I find the curbweight interesting. 1400 kgs is suppose to be camry / accord size. But both of those are BIGGER than that, currently. I would expect that the volt would be the same.
