To summarize all these patents, less energy is expended for the catalytic decomposition of water.
Than what we can get by burning the resulting hydrogen. Do I understand correctly?

Is it necessary to decompose water certainly  to hydrogen by your low-temperature catalytic methods?
Why not get another combustible substance from the water at once, for example, methanol or methane.

Maybe silane? Good thing. Even spontaneously ignites.

So I spoke again with a friend who read of this challenge!(Jerry V. at Peters open source forum)
Seems the Thomas Edison water fuel challenge
WAs an Ounce of secret green fluid
Mixed with one gallon of water
Ran an internal combustion engine !
Edison put out a very big reward for the time …to anyone who could tell him what this one ounce of Green fluid was ?
 A long time passed … no one came to answer the challenge ( successfully)
And he just published it
 
Acetylene mixed with acetone at 200 atmosphere
Fellow who shared this said “might need to cool it during the process “?


Go small at first !( samples)


Wonder how it “do what it do “ ??
Effects thermolysis ?
Or ….
 This one gonna be wild !
3000 psi ?  ( to make a solution from such a touchy soup


Hmm
Seems to share bits from the Brax peace collection

Sir
Biology and water splitting, irresistible combination


Snip from your link
Photocatalytic water splitting is an artificial photosynthesis process using photocatalysis for the dissociation of water(H2O) into hydrogen (H]2 and oxygen


2. Only light energy (photons]), water, and a catalyst(s) are needed, since this is what naturally occurs in natural photosynthetic oxygen production and CO2fixation.[1]
[2][3]][4]
Hydrogen fuel production using water and light (photocatalytic water splitting ), instead of petroleum, is an important renewable energy strategy.

PS
Sam leach claim with lithium nitrate at 20ppm and 500 psi runs ICE
Is still in the works ( access to nitrate an issue …any suggestions?)
And now we see Herman Anderson ( soft X-ray claim ..was not Myth or ?

Sergh
Thanks for reply, I was on road all day yesterday until late !


Will look for relevant quote and post here (from Herman on soft X-ray )actually he supports your comment and it might be good to define this issue you mention !




Studying your other contributions ( you truly are a wonderful resource for the Hydrogen technologies !
Many are quite interested since it seems more possibilities for open source  builders to explore with huge potential!
For perspective Sam Leach lithium nitrate at 20ppm at 500 psi in water runs ICE …is within grasp of many experimenters !
Many areas you point to here are in same category ( we have skill set to experiment in open source community)
With gratitude

Have you heard about the used oil furnace from 1950's that ran on water? Patent was issued to army service men in Texas for only adding water line to T fitting for used oil burner on used jeep engine oil, to get 50% increase in efficiency. That was not what was written in their application for Patent. SS coil tubing in brick insulated firepot of oil burner hooked to input common water line. Oil furnace started. Oil passes through spring operated  one way check valve. Temperature gauge monitored for temp up to 1500 degrees F. Then valve opened so as superheated steam is allowed in T fitting with oil to tiny nozzle. Nice burn flame runs constant. Then oil line shut off. Furnace still runs. Shock wave from 90 lbs pressure to zero AMBIANT in fire-pot forms Hydrogen and Oxygen torch flame that also heats heat exchanger. Normally water molecules separate at about 3000-6000 degrees which is too much energy. The vibration shock wave allows for disassociation at lower temperature. Electric motor with dual shafts ran 2 oil pumps at 90lbs. If water shut off, and cooled down, then furnace has to be restarted on oil. A much smaller unit in crate was shown to a US senator in Washington building underground parking , as an open trunk display. This was somewhat similar to the propane operated camping stove with circular pores, ignition igniter, vertical round fire brick insulated chimney, and interior SS tubing of water. When steam introduced to T fitting, the fuel used was shut down leaving burning circular torch flames. It probably used minerals free distilled water so as nozzle would not clog. (US Patent office not allow for overunity for public.- Free Energy is eliminated in issued US Patents. US- 1958, 2,863,499.

US patent 2863499   shows only SOME of the original data . At least you get the general  idea. Type number in CAREFULLY to study Patent issued. (oil furnace ran FULLY on water in 1950's, after starting with fuel oil, and up to proper temperature- from original manuscript submitted.)
