I am seeing news about new car companies popping up selling electric cars. They seem like they're finally getting it right. They're big, fast, look cool, and can drive from A to B without needed to be recharged. So far, what is out there and what is on the horizon?
Answer
The hype is a bit ahead of the car.
The Tesla Roadster is probably the most exciting car that's actually being produced. It's fast, has a range over 200 miles and looks cool. It's small and costs $99,000, so not really a commuter car.
The Phoenix motorcars truck is very cool, it's $45,000, but due to needing tax credits it's only being sold to fleets. It's got a lower range of around 150 miles, a slightly lower performance level and not as cool, but it's got the huge advantage of being able to recharge in less than 10 minutes, if you have a charging unit.
The rest of the production cars now are more what people used to think of electrics, slow, small and long charging without much range.
What's coming up that's the most exciting to me is the Chevy Volt. It's a series hybrid, which is totally different from the Prius. It has an all electric range of 40 miles, which covers over 80% of the average drivers commute. After that 40 miles a generator kicks in charging the battery. The generator can be of any type, gas, diesel, fuel cell or something crazy that comes out.
The range without consideration to the battery is 600 miles, the mpg is supposed to be 50 after it's purely generator driven, so there is NO convenience issue with this car.
I think this is the car that can change things, under $30k price tag as well. 2010, and production development is underway, so don't let people tell you it's GM hype. The car was in union contract to be built in the U.S. so if you're patriotic that's a bonus as well.
Every big car company is coming out with prototypes now, and some look good, the suburu has the model I like the best as far as looks, but no stats have been released.

how dose a multi fuel diesel engine work with a fuel like gasoline?
redryan
any one have any Idea how a multi fuel diesel engine work, how can a engine that is designed for diesel work with outer fuels.
Answer
Some diesel engine designs can use a variety of biofuels ...the injector pump can be altered while driving to inject bio fuels of varying energy content via computer controls and switches. Another design which can incorporate gasoline fuels using diesel engine compression and ignition is called an HCCI engine...Homogeneous Charge Combustion Igntion..

http://en.wikipedia.org/wiki/HCCI
Other designs incorporate very precise timing to inject gas and diesel fuels in exact amounts....the drawback is you have two fuel tanks...one for gas and one for diesel.
