Around 2.60 for the cheap and 2.90 for premium.

Getting hydrogen isn't as simple as one might think. True, it is in
abundance in water, but extracting it requires a powerful electric
current, machinery to capture and condense the hydrogen gas into liquid
hydrogen (the only real effective way to store and utilize it) and the
fueling stations and the hydrogen cars alike have to both find ways to
keep it effectively (liquid hydrogen's resting temp is in the area of
-250 degrees. Celsius. Brrrrr)

So yea, Corn is easier. Still, it seems hydrogen is making a lot of
people excited, so it could be the wave of the future. To me, however,
Using already established technology (the diesel engine) with a few
modifications (a heated fuel tank) and an abundant source of fuel (corn
oil) makes more sense to me. We should know in about a decade or so.






It is simple to extract hydrogen from water. Ive done it before
with materials from my house. A large scale one could be easily and
cheaply made. It does require electricity to extract it but that can
come from clean methods like solar, wind or hydro. Capturing it is even
simpler and you dont have to liquify it. You simply use hydrides to
store the gas. The production of biodiesel requires methanol and lye
(two chemicals which are expensive and are not available in large
enough quantities).

Cheaply be made? are you kidding me? How much energy was
required for you to extract the tiniest bit of hydrogen from the water?
ALOT. It's not worth it right now, it takes far more energy to produce
the hydrogen than what the hydrogen will be used for. Also there is no
effective way to store the hydrogen in a vechical because it will take
up far too much space and weigh too much wich will kill
efficiency.


On the contrary, for a science project a kid used an old half dead car
battery to extract about 2-5 cublic feet of hydrogen from water.
The battery still had enough power to make more.

Its also the lightest elemant known to man, I dont think weight will be a huge issue.   <!--

I hate to tell you but you're wrong. Breaking an oxygen/hydrogen bond requires a huge amount of energy, 2.5 cf is not a lot, trust me, there is a lot of energy needed.

Don't blame me, I voted for Kodos.

Breaking the bond doesnt require lots of energy. I used an old 9 volt battery in my experiment and although it didnt produce lots of hydrogen it did break the bonds. The energy for a larger scale one energy can come from renewable resources like solar, wind or hydro. A person can create enough hydrogen for hundreds of miles worth of driving in a day (which is enough for a city person) using only the power from a standard outlet. (IE a few cents worth of electricity a day)
