Just ran across this, I have read a bit about using heat rather than electricity to crack water before, it is called "steam reforming, reading about it it seemed to require temps hotter than those available from the engine exhaust but it looks like it may be doable at exhaust temps. In reading I have found several referances to cracking water into HHO by contacing superheated steam with a hot glowing iron rod, apparently this liberates a good bit of hydrogen, in researching wood gas gasifiers I know this process takes place when steam contacts glowing charcoal so it seems it might also work with glowing iron?

There is a good bit on BS about magnetic resonance and other mumbo-jumbo crap around this process but I suspect it is simple steam reforming.

The fellow in the video apparently has had legal problems of some type with the state of Utah and was held in a mental institution for some time? all sorts of opinions on that apparently.

There are MANY videos on Youtube of versions of this apparatus powering small engines, the engines are shown running but I have yet to find one that is powering anything to indicate how much power can be made using this technique. It does require a small percentage of flammable fuel along with the water but the concept is to pre-vaporize the fuel before it gets to the spark ignited engine so apparently any type fuel can be used, gasoline, alcohol, lube oil, grease, etc.

Just started looking into this but If you can produce HHO by using the waste exhaust heat rather than by using engine power to make electricity then it is a completely new ballgame, by using wasted heat that is already available it won't matter that it takes more energy to split the water into hydrogen than you get back by burning the hydrogen. (MIT has an on-vehicle fuel reformer called a "plasmatron" that reforms liquid hydrocarbon fuel into gasious hydrogen directly on the vehicle, it uses a plasma flame to do the reforming)

This links to a 3 min introduction video of the concept.

This 10 min video shows several engines in operation, from a single cylinder engine up to a 480 HP generator engine.

Apparently there is a Yahoo discussion group concerning this process at
tech.groups.yahoo.com/group/VortexHeatExchanger

A forum search for "geet" found 3 other discussion entries.

I think that reformer technology requires a platinum membrane . It could turn out expensive to experiment with this.

There is (was) an engineer at Bradford College (uk) who was considered on eof the leading people in this field. Can't remember his name.

From reading the "read this first" file at the Yahoo group it says this device is a "self powered plasma" fuel converter and does not use either external power or any type catalyst. The externally powered MIT Plasmatron has proven that a high energy plasma will break liquid hydrocarbons into basic hydrogen, this GEET device seems to be attempting to self-generate the high energy plasma by using the hot exhaust gasses flowing over a hot magnitized iron rod that has wire coiled around it, sounds interesting and may be something to it, I don't yet have an opinion, just started reading about this concept myself. It may actually be more than just simple steam reforming, even if the "self-powered" idea does not work it should be easy enough the form the plasma using a high DC voltage produced externally using the vehicle's 12 volts.

Producing multiple thousands of volts of high voltage with miniscule current takes very little power, this is exactly what all spark ignited engines already use for there spark plug ignition systems. Even if it takes a couple amps to produce the high voltage hopefully the concept of using high voltage plus heat from the exhaust system would liberation far more hydrogen fuel energy than it takes to create the high voltage?
