Subaru Enthusiasts Car Club of the Sierras - View Single Post - Inject hydrogen into your intake = double the mileage

From Mike's last link:

Now we're getting somewhere... finally something that makes a little sense. This I might actually believe. But the system they're describing would require a properly metered hydrogen injection system, not a mason's jar with two electrodes and a plastic tube.

And what else I'm curious about... if it takes such a small amount of hydrogen, why not just have a small carbon/kevlar pressure tank of the stuff with a regulator controlled by the injector duty cycle that bleeds the tank off into the intake? It would be smaller, lighter, probably safer in a wreck than the car battery is, not sap power for electrolysis, cheaper to produce, and more reliable than these goofy on-demand systems. And if you didn't want to have to fill them up from a gas supplier, you could still have the option of running a home electrolysis unit off the grid power in your house which is much more efficient that running a gas or diesel motor to do it on the fly.

Anyway, I'm at least seeing someone make an attempt at a real explanation at how this could work, but I'm still not convinced that it's just not a more sophisticated version of the same scam. If hydrogen really makes as much a difference as they claim it does, why isn't this on production cars? How much did Toyota spend to design the Prius to bump from 30 mpg to 45 mpg? Didn't they know they could have gotten 55 mpg just by boiling some water into the intake?
