Electric vehicles are making a big comeback now that some of the battery problems are being solved. That was always the bug in the ointment with EVs, the batteries cost about 2 grand to replace and just didn't last very long OUCH! The newer lithium-ion batteries like your laptop uses are being used now to power the next generation electric cars like the Tesla or the Chevy Volt (hardly compares IMHO). A huge improvement and consequently, the cost of operating an EV is down to about 2 cents/mile now. That's pretty cheap compared to gas nowadays. There have even been recent improvements in Lithium-ion batteries themselves. The major oil company I work for has contributed to the effort Yeah, they're working on EV technology as well as fuel cells because the next generation of EVs will use fuel cells instead of L-I batteries. Those should really be something!
ExxonMobil Chemical's new film technologies help power next generation hybrid and electric vehicles
November 28, 2007
ExxonMobil Chemical and ExxonMobil's Japanese affiliate, Tonen Chemical, have developed new film technologies for lithium-ion batteries with the potential to improve the energy efficiency and affordability of next generation hybrid and electric vehicles.
These new film technologies are expected to significantly enhance the power, safety and reliability of lithium-ion batteries, thereby helping speed the adoption of these smaller and lighter batteries into the next wave of lower-emission vehicles.
“By developing new film technologies that allow lithium-ion batteries to meet hybrid and electric vehicle requirements, ExxonMobil Chemical is helping to make next generation vehicles more energy and cost efficient, as well as lighter,” said Jim P. Harris, senior vice president, ExxonMobil Chemical Company. “We are currently working with industry-leading battery manufacturers to expand the boundaries of current hybrid and electric vehicle applications.”
Separator film is an integral part of battery system design and critical to overall performance. ExxonMobil Chemical’s new technology platform builds on twenty years experience in lithium-ion battery separators, applying advanced polymer and process technologies with flexibility to tailor products to battery manufacturer requirements.
ExxonMobil Chemical will present the new film technologies at the 23rd Electric Vehicle Symposium and Exposition (EVS-23) in Anaheim, Calif. on December 2-5, 2007.
And yeah, I know the word on the street is that 'big oil' tried to kill the EV. To the contrary, all of the majors are actually actively involved in researching, improving and implementing the technology. Most have partnered with auto companies and universities in this effort. After all, money is money and these companies are in the business of providing for our energy needs. They'll deliver what we desire, in a capitalist economy the consumer is king.
The first ones are becoming available this year but most are already spoken for. I know the minute I saw that Tesla roadster the other day I put it at the top of my wishlist (and the Lamborghini Gallardo occupied that exalted spot before if that tells ya anything)
Here's a link to the Tesla Motor site:
and one that lists the top 10 electrics you can buy right now according to AutoblogGreen
and a link to the electric car page of a cool site called 'how things work' and you can navigate through links from there to how fuel cells and all kinds of other stuff works:

What do you think? I know I want one!
