ahh your numbers seem pretty suspect to me man $26 in E ? you do realize HOW MUCH power that is right? for me thats 191,000 watts at full commercial pricing (electricity at work I have not done a cost break down at home yet) at work out bill comes to 13.6cents a kiklowatt.

your going to get a hell of a lot more than a "gallons equivalent" of hydrogen out of 191,000 watts worth of electricity.

I don't have solid data on this but one number pops to mind of .8 liters per minute out of a 12amp generator.

so thats what ? .1liter a minute hydrogen .7 liter a minute oxygen or close to that?

ie 6 liters per hours of pure hydrogen. Thats 156watt hours. if we assume 90% efficiency in the charger (EASILY possible with todays $40 digital chargers I think mine says 89% and it cost me $18) so that means from the grid I would cosume 170watts roughly per hour. so $26 in grid electricity would run that generator example for 1,123.5 hours WITH efficiency factoring built in.

or produce 6,741 liters of Hydrogen Gas and 47,187 liters of Oxygen. for $26

are you seriously telling me that it takes 6,741 liters of Hydrogen Gas to equal ONE GALLON of gasoline? I admit you could be right I have no ideal how much the H2 equivalent is but I find it excruciatingly hard to believe its 6,741 liters. (1780.8 gallons of Hydrogen)

Can someone chime in with some data to back up or refute these figures either way?

BTW some quick math. I plan to run at least FOUR generators so thats 2.3 cents per hour per generator. or 9.2 cents per hour or about 12cents per "trip" to work (1 hour 20 minutes) which comes to about .222 cents per mile.

if it gets me even 3mpg here is how the numbers play out.

I average 40,000 miles driven a year. at my current 47mpg assuming $2.50 a gallon thats 851 gallons of gasoline. at 50mpg thats 800 gallons of gasoline

or 51 gallons of gasoline or $127.50 savings per year. The Generator will cost me $88.8 dollars a year to run.

The generator uses crap I already have and about $12 in crap I did not have (namely the threaded rod and stainless plates) either way I am going to ignore the cost of the generator since its #1 so cheap #2 can be made with stuff you already have.

the charger is also zero as I already have them (and so should most people)

the only thing you REALLY need to buy seperate is more batteries. lets say 2 batteries deep cycle. From the u pull it in working condition $20 a pop brand new $40 a pop for a cheapy deep cycle. so $40 to $80 in batteries depending on which route you go. I would assume $40 since you won't want to spend more money till you know if its going to work.

So after a FULL YEAR of usage I would have saved $127.50 in gas (this assuming gas STAYS at $2.50 yeah right :-)

and I would have SPENT $88.8 in E and $40 in batteries for a total of $128 so in reality if you already have a charger you would SAVE money in your first year. NEXT year you would save $40 in fuel.

if you count that fully 50% of my charging would happen at work where the E is FREE to me I would save over $40 in my FIRST YEAR and $80 the next.

and this assumes only a 3mpg gain on a already REALLY high mpg car a Geo Metro.

now try crunching those number for a 15mpg or 20mpg car with even a 1 or 2 mpg gain.

the LOGIC is their. The question is "will it work" I really don't know. one of these days I will find time in my schedule to motivate my lazy ass to find out :-)
