I think it would generally be impossible to have an hho unit supplying
all the overunity energy gain required to overcome both ICE engine
inefficiency plus not loading the engine via the initial current loop to
really run at high loads without some kind of storage. Especially at first.
hho storage is out because of the risk of a recombination explosion.
hydrogen storage is out because of the need for compression and the
danger of mechanical tank blow-out, and battery storage is out because
you may as well just use one big battery.

So to me it makes sense to run hydrocarbon fuel *plus* internally
generated hho fuel hybrid system under control of electronics.

When the engine is hot and the load is low we would begin generating
hho to try to equalize the load on the engine over time. So we would
load the engine via electrical generation and make more hho, as much
as possible trying to have the engine run itself on hho as fully as
possible. The engine's core temperatures would eventually begin
to drop while running from almost pure hydrogen.

When the engine is cool or its loading is high we would raise the proportion
of hydrocarbon fuels burned and a lower percentage of hho. The engine would
now begin to heat up, and the lowering of electrical production would decrease
load on the engine so that it could supply the real load.

Basically the engine would *excurt* into hho production, and try to keep
it's loading somewhat constant with time.

I think this is more realistic then full hho. It would work independently
of the overunity gain of the electrolyser. So it could live through several
electrolyser design iterations. It would keep engine temperatures higher
and pseudo lubricant (and plasma suppression) properties of hydrocarbon
fuels somewhat intact.

Actually, a hybrid vehicle would be an interesting place to try this as the
engine has a very powerful generator/alternator to load it. Full hho
operation is therefore most likely in a hybrid.

according to 6-10 lpm hho for a 5 hp engine i could run my 1.5hp with 1.8-3 lpm on full hho

i dont consider it to be unrealistic when you look at the past history of production and some other interesting aspects of water. what i see is how efficient can it get?

considering that i need (presumably) 2 lpm min to get my lawnmower to work lets do the math. 

faraday said per cell we need roughly 1.8v at 1.5 amp now if you run series cells the efficiency gets better so lets assume we start with 3 cells. its going to take 60 amps, increasing the number of series cells the amp draw goes down. depending on the battery we can get more series sells with less amperage and increase our output.

its not that unrealistic even in faradays world, today we have pwm's and other gimics that increase efficiency and thats just what i have seen on my coffee table. if some of these myers cells or others work its even better.

consider the alternative electric motor and even if we do have to recharge it, it will take less electricity to run hho than electric motor.
