Well, i wasn't talking about the costs involved in obtaining petrol or hydrogen, but more on the efficiencies once either one is burnt in an engine.
If we are adding the costs you mention to the overall efficiencies though...
One could also argue the efficiencies of gas/petrol fall further once you factor in costs of oil prospecting and extraction, costs of transportation to refineries, costs to refine into petrol, transportation to the pumps, power to the pumps...
Where as for Hydrogen, if we are talking costs of electrolysis, it's basically electricity (which if need be, can be derived from sustainable sources such as wind, solar, wave, hydro, or even from waste fired power stations) and water.
No extraction, transportation, refining, and all of the other costs associated with petrol, including the environmental costs.
Hydrogen is also the most abundant substance there is. It's in virtually everything in a surprisingly high percentage. Not just in water, although water is the preferred and easiest way to obtain it. Liberation of it though, is where the smart research is at the moment. And efficiency progress is being made constantly. More H for less energy cost, is something that is getting a lot of attention these days, for obvious reasons.
I didn't know WM sold 17kw generators...cool. Propane powered as well.

Looks like pretty standard pricing for that generator - not necessarily the best deal.

Whether or not hydrogen is considered a chemical or an element is a matter of semantics. Hydrogen is the most abundant element in the universe. Whether or not it is the most abundant on Earth depends on how you look at it, by mass or number of atoms.
You avoided my question about how to collect hydrogen in space.
You also avoided my question about what helium-3 has to do with any of this.

Phage, all I ever see you do is argue. Besides debunking stuff now and then do you ever contribue something positive to ATS?

Decreasing the ever-rising level of bunk on this site is a very positive thing. I'd do it myself, but I just don't have the stamina any more.
Electrolysis is one way to collect hydrogen.
Vacuum and space is another way.

Apparently you put that up that second post at pretty much the same time I posted my response to your first one, five minutes after your first one. I didn't see your second post while I was posting my reply to your first. I can see no response to my question about the collection of hydrogen in space or the relevance of helium-3. All I see is this;

You aren't thinking on the macro level.

Gosh! I have one right in front of me. And its pointed right at my head!
The cathode ray tube (CRT) of any TV or computer monitor is really a particle accelerator.

For all intents and purposes, the electron is virtually massless, particularly when compared to protons and neutrons, which are the primary constituent particles responsible for the mass of an atom. The contribution of electrons to the mass of an atom is negligible. 2000 times as heavy as an electron

Everyday examples of particle accelerators are cathode ray tubes found in television sets and X-ray generators.
This is a small electrostatic particle accelerator, built in my senior year of high school(2002-2003). It is designed for electron acceleration.
