A lot of Energy is lost, with each conversion. I mean that the more steps you take, then the more energy will be needed to drive the conversion process? Also producing more CO2. This link has (plausible, alarming)FIGURES for waste at each step. His idea: producing fuel oil by reacting hydrogen with coal (hydrocracking) would be much less wasteful, than liquifying the hydrogen, and using it as a fuel. Or converting it to electricity , and charging electric cars with it.

Compressed air might be more practical than batteries, since the volume increases faster than the weght. The article doesn't discuss the energy lost compressing air, I think it'd be at least as much as charging a battery. but the tank wouldn't cost as much ,wear out as fast, be so affected by cold, and not a toxic mess.
The article discusses using waste heat from an electricity – generating power plant, to increase hydrogen electrolisis efficiency to 50%. also, the waste heat would be a big saving on the "hydrocracking" process.
The alternative to finding a practical method of powering our civilisation is to wait for most people to die, and then there will be enough land for the remainder to become subsistence farmers. It seems obvious to me that hydrogen and batteries will never be practical. the article explains it well.
i agree about drilling ANWR, and using nuclear power. Imagine the oil that the navy has saved, with nuclear powered ships. Those nuclear aircraft carriers only need to refueled once in their lifetime. I disagree about the CO2 hazards, and think it'd be a real shame to let AGW, or the fantasy of hydrogen fuel distract us.

you still have to work. The solar panel system that charges the bike is 3 x 80w panels on the roof, down to 20A regulator and 4 x 130ah deep cycle batteries up to a 600w pure sine inverter. The bike draws around 50 amps when charging the battery, and a full charge takes around 4 to 5 hours or so. The solar setup is of course overkill for charging an electric bike, but I use the solar power for other things too. Eventually I’d like to build the solar kit to charge an electric car, when that time …

Well I'm opting for a car that doesn't have a running engine, but still has a nice body/chassis that I could work with. Basically, my options are these:
Subaru WRX 2.5rs (older GC chassis ones)
Datsun 240Z
Acura Integra GS-R
Honda Prelude (4th or 5th gen)
So those are my options as cheap, but still high performance vehicles. I want to swap out the combustion engine with an electric motor, as well as add the necessary components with it (batteries, fuse, et cetera) Now here's the problem:
My main problem is that I feel sort of uneasy about putting a bunch of batteries in front, so I PREFER (but not require) to have them all resting in the back. Granted, this will cause weight unbalances.
I think the best cars are the Integra and Prelude, since they're already front heavy, but front wheel drive cars have an issue with understeer. 240z needs restore first and will be even more rear-heavy. Best is WRX, but not sure if I could put power to all 4 wheels with just one electric motor.

It’s a convertible. It was cheap. It has four seats, and a musty smell. And he’s past the point of no return. Join a totally non-mechanically-minded newbie on his quest to build an electric car that doesn’t look like it fell out of a cornflakes box.

The endurance of electric cars is soon to receive a timely boost. One California company unveiled a solution — a prototype energy station that swaps electric vehicles’ empty batteries for fully charged ones. The Better Place Company hopes such networks would replace existing conventional gas stations sometime in the near future. [Yoav Heichal, Chief Engineer, Better Place]: “A switch station is actually a gas station for electric vehicles. But it’s clean because you’re using the energy …

For my physics class a project was assigned in which we have to build an electric car powered by a 3 volt DC motor which could only be powered by 3 volts of battery power (in other words 2 AA 1.5V batteries). We just started learning about circuits so I don't have a very good knowledge about this kind of thing but I was wondering if there was any way to increase the power going to the motor without increasing the output of the batteries. I thought about a transistor to increase the voltage but if the motor can only take 3 V would it blow the motor if more volts were added? Or is there some way to increase amps instead of voltage that would assist the power. In case it helps I am planning on using the 3 V DC micro-vibration motor from radioshack.

After successfully testing the drivability, it’s back to the workshop to get stuff removed to paint the battery racks and sort the best place for the charger and finally add the tacho sender to the gearbox adaptor plate. The fuel port assembly is done now also; I cleaned up the inner rubber mount and gasket-sealed the hole with a rubber bung where the original fuel inlet was, and Nathan cut out the new hole for the power through to a new fascia plate where the 20A connector will be mounted …

Yeah he pulled the gas motor out and installed a electric motor and some batteries in the trunk with a charger and he plugs it in with a extension cord, he say it cost him for the whole month to go back and forth to work. Wow huh, he said the conversion cost 00.00, which is cheap if you think about this gas going to per gallon by next summer. It was in the Dallas paper, heck at that savings I could get a throw down car for running around town and save the gas hog for trips on the highway.

I'm interested in and committed to converting a conventional car to electric, but I really know very little about cars or electrical engineering.

Here's what I have done so far (most still makes no sense to me):

Read Bob Brant's book, "How to Build an Electric Car"
Sought help from my local EAA
Used online EV calculators
Researched a bunch of motors, controllers, batteries, etc.
Visited the Austin EAA photo album and looked at others' EVs

I'm looking for specifics if anyone has them.

Could anyone give me recommendations of parts or other info to refit a sedan with a manual tranny and a curb weight of 2100-2300 lbs that could get me roughly 75 mph top speed and maybe 60 miles per charge with a budget under k?

Thanks!
