Yes the First Diesel Engine was meant to run off of Vegetable oil.
At this moment it would take less money to produce hydrogen as far as electrical and water cost, but as the price to produce energy raises so will the cost of electricity proportionately.
You have to remember that most electricity is produce using one of 3 sources.
Hydroelectric turbines.
Natural Gas.
Coal.
They are working on producing Gasoline from Coal, now this is a viable option, but it won't come cheap.
Natural Gas, I remember that back in the 1970's there were city cars running on Propane and Natural Gas. The Problems with these options are that there is a lot of modifications needed to be done to a vehicle to use this option, also the draw back to Propane is that you still have to deal with the oil Companies. Natural Gas would be the better option.
Electric cars are great, they have outstanding 0-60 proformance but you are extremely limited on the distance you can travel.
Don't feel bad about the Job Situation, I quit after my Boss screwed me out of $1,000 and has been blowing smoke up my ass since Christmas. I gave the man the benefit of a doubt, but I can only wait so long for what's owed to me. Also he screwed me for $225 on my last pay check... That's ok, I get to watch him squirm now, the IRS is after him for Tax evasion.
while it would be nice to have an alternative to todays car it wouldn't make a difference if you can't afford one
.... I'm broke too ATM, so theres no sense to look into buying a kit until I can afford it....

confused: or real high viscosity at lower temps.) at around ~40 degrees or so(don't quote me on that one). 
.... Another example of focked up politics.. But that was just hearsay from the internet and I haven't looked it up because I doubt they would disclose that technology to the public for obvious reasons. I'm sure thats why they said " I don't understand why the University of Queensland says that they would have to rewrite the laws of physics though. The concept is simple, it works off of magnetic repulsion backed with an armature..." because they don't want the public to be certain of it, and to have us sheeple guessing if its real or not.... If the technology is real, than we should demand that we should be able to supply our own houses with this technology because ITS FOR THE GREATER GOOD. These people(politicians) are supposed to be working for us and not the other way around...
