    To "produce" millions of gallons of crude oil you have to expend the energy to drill a hole in the ground. To release some portion of that energy you need the energy of a single match. See the burning oil wells in Iraq. The energy from burning oil is the energy source used to crack it.

    Read Moby Dick. I call your attention to the chapter entitled The Try-Works, wherein Melville describes how the rendering of whale oil is fueled by burning whale blubber.

    In both of these processes you end up with less energy available at some future point then when you started, but still with a surplus over what you had when you began.

    You gather a surplus of stored solar and geothermal energy and waste some of that making it into a more usable form.

    Let me repeat. For every atom of hydrogen you produce you must add energy to it.

    Let me repeat it again. For every atom of hydrogen produced you must add energy to it.

    This is why methanol is produced from oil. You can use the above process, wasting some of the energy stored in the oil to refine the particular hydrocarbon you seek from the crude oil which is found energy. That's why we use it. That's why our houses are warm and our lights glow. Because coal and oil are found.

    Yes, there is lots and lots of hydrogen in water, but it isn't "found" because it isn't a store of energy, it is an energy sink. You must add energy to the water to release the hydrogen. You cannot burn the water to produce this energy. Typically you use electricity to do this. Electricity generated in a power plant burning coal, oil or nuclear fuel.

    Crude oil is noninterest bearing capital. Slush money left under the mattress by an ancestor.

    Hydrogen is debt.

    Using that capital to finance debt for daily living expenses just uses up your capital faster than living off of the capital itself.

    Catalytic cracking from methanol is another possibility. Energy must be used to refine and manufacture the catalysts( and those catalysts expire, requiring energy to dispose of), as well as to produce the methanol. See above reference to the second law. The quickest dodge around the outside of the second law in this case is to use some naturally occuring process to reduce the energy need.

    Ah, but what about that bioethanol the article talks about, I hear you cry. That isn't made from petroleum oil.

    No. It isn't. Then why is it so expensive? Because of the energy needed to grow the plants ( do you know how much fuel is used in farming?) and the energy needed to produce the ethanol from the plants. See the second law.

    Effectively all hydrogen on earth is in a bound molecular compound. Energy must be added to free it. See the second law. Producing hydrogen will always be done at an energy loss.

    From whence will we derive the energy to make up that loss?

    Ummmmmmmmm, oil?

    There's no such thing as a free lunch. You can't win. You can only break even. Oh yeah, and you can't break even.

    There are many benefits to be derived from using hydrogen as a fuel. Saving energy from other sources isn't one of them. The big energy companies, even those specializing in oil and nuclear, are going to frikkin' love the "hydrogen economy."
