Robert Dewey raises the question why we are not more actively pursuing
hydrogen-powered cars. Part of the answer, I believe, is that free hydrogen is
not available for collection, as are the so-called fossil fuels. It must be
manufactured using a process that consumes more energy than is available in the
resulting hydrogen. Kerry J. Thompson
In other words, hydrogen is not an original
energy source, only a method for storing and transporting energy. Some other
energy source is required to produce the hydrogen. When all things are taken
into consideration, it may be the right thing to do. However, it is not the free
lunch envisioned by some.
