OT:
what numbers bro? you mean the density you have given? for comparison, the following are the density of some common gaseous fuels at standard temperature and pressure:
(density in kg/m3)
hydrogen - H2 - 0.0899
oxygen - O2 - 1.4290
propane - C3H8 - 1.882 (@ 20°C)
butane - C4H10 - 2.500
hydrogen gas has a large specific volume (the inverse of density), meaning it occupies a lot of space for a certain mass. even though hydrogen has a large heating value, it has a very low critical temperature and high critical pressure (compared to the other three gases), which is why it is difficult to store large amounts of this gas in tanks. propane/butane, or LPG, can easily be liquefied. at the same volume (e.g. volume of an 11-kg LPG tank), the mass of LPG that can be stored is much greater than the same volume filled with compressed hydrogen gas. thus the amount of energy that can be supplied by the propane/butane mixture is higher.
hydrogen - 141.80MJ/kg (higher heating value)
LPG - 46.1MJ/kg (higher heating value)
also, hydrogen "interacts with many metals to reduce their ductility":
Hydrogen Embrittlement of Metals: Atomic hydrogen from a variety of sources reduces the ductility of many metals -- Rogers 159 (3819): 1057 -- Science
Bro vernie , maau kay naa kay time ug funding cguro ani. padayon bro sa imong nindot nga project kay if ma perfect na nimo pataod unya mi. Panahon na cguro nga ma amend ang ubang law sa thermodynamics kay morag naa man pod to laing topic about sa fuel less generator nga makausab sad sa ubang law sa physics. more power..
lisod man na ang water gyud ang ibutang directly sa car..hasol na kau if butangan pjud nmo ug electrolyzing mechanism ang car....on the matter of the inefficiency of hydrogen production and storage, wouldn't all these problems be moot if the energy we used to extract hydrogen is free,renewable and clean?..i can't believe no one has stopped and come to think of this..for example, what if the power generated by solar,tidal,wind and other various renewables was used to separate hydrogen from water? the question of efficiency wouldn't be such a factor since the energy we use is basically limitless. mind you..this thought can not only be applied to hydrogen production but we can also apply this in desalinization plants(the energy required for reverse osmosis would come from renewable sources)..think about hitting two birds with one stone..

problema man gud sa pag kakron aning clean and renewable source of energy kay pirte kamahal compared sa fossil fuels.
i think initially mahal xa tungod sa capital pra sa machinery but in the long run dili kaha mas cheaper kay dili nman mogasto after ma-put up? keysa magsige og palit sa fossil fuels? asa kahay mas barato bro?
sukol man gani ang mga tao mag pataud ug LPG kit with dako dako nga initial cost for the kit thinking makabarato sila sa cost sa per liter sa LPG, unsa kaha kung ang cost sa per liter sama nalang sa cost sa tubig sa gripo (less than 50 pesos per cubic meter)? Unsa kaha kung ulan nalang gyud ang kuhaan sa tubig? Unsa kaha kung sa dagat nalang mokuha ug tubig?
check this video, eye opener pud ni nga something not the usual is very possible (related sa using water to run an engine):
Baron New Energy introduction video (Joe Cell)
7:23 nga part sa video gipakita giyab-an ug tubig ang carburetor but the engine keeps on running.
