It sounds reasonable that injecting H2 into your fuel stream can
improve the combustion.

Hmm, I dunno, I feel a little puzzled or suspicious of how he's
achieving a net energy gain here. Can anyone debunk any obvious
fallacies here?

I'm not up to trying to read all of the web site, but the answer is to save
your money.

Water injection has been around in high HP engines, running at high,
constant loads, for a long time. Will it become practical for your airplane
or car?

Car, no, because of the low HP, and non-constant loads.

For airplanes? Yes, if all you want is a boost of extra HP, for a short
amount of time. Some WWII fighter planes used them for an extra boost for
take-off and for other times, such as dog fighting, where the extra HP meant
life or death. Some air racers also use water injection.

Why not all of the time? LOTS of water is needed to make much of a
difference, and the weight for enough water to last for more than a few
short bursts would be impractical to carry around. It also needed a lot of
monitoring, which no doubt could be taken care of by modern micro chips.

Lastly, if it was a viable option, wouldn't all major manufacturers be using
it? You will have to ignore the oil company conspiracy theories, to answer
that one. g
