I vote we have one person that thinks it's a scam and one person that believes the logic each build one and run it for one month (good sample size) and compare it to the previous months average. Error factor will be decided on variations from previous months before the test (if your vehicle gets 20 one month and 24 the next and 22 the month after we'll use 22 as a baseline with a +-2mpg error factor).

Who's in?

There are people that believe the logic, and think it's a scam too. HAH

But yeah i second that.

I can try in a couple of months, but for now i don't even have old data (baseline).

Although i believe the logic, I'm skeptical that enough hydrogen will be produced to make any difference.

willy57, wow , very diverse group eh. great learning tool this forum. now if we could just get plants to make fuel out of sunlight, co2, H20, and soil.

I thought I posted in this thread yesterday, but the intertubes must've ate it. Anyway, from what I've read, the addition of hydrogen into the mix 'effectively' increases the octane rating of the fuel. This means that you can run higher compression and leaner air/fuel mixture without detonating, resulting in more power . In the 70's when we were all running leaded fuel with 99.7 (RON) octane ratings, the compression was higher, the cars had more power, and fuel economy was only slightly worse than it is now.

I believe the technology does work, but that you'd need to do more work than bolt on a hydrogen generator to see any _significant_ gains.

I found some numbers of interest on the site of the _one_ canadian company selling these that has government verified numbers. 13 amp draw, 4 litres of water per 10,000km (~1 gallon / 6000 miles) and a verified improvement of 4%. The company guarantees you'll see 10% (on a tractor trailer I'm assuming).

lol, like ethanol, wait, now if we can just get the ethanol to stop taking on water from the air and stop eating the seals in peoples rochester carburetors, we might be onto something.

Anyway... We need the food these days more than the fuel. What we really need to do is make the manufacturers stop putting power everything and airbags and side impact door beams and huge windshields in cars. Oh yeah, and how about they actually use the technology that they have access to instead of just holding it. Like hey, where the hell is the EV1 these days.

Everyone go rent "Who killed the electric car?" from net flix. It is an eye opening experience that all eco minded consumers must see.

I couldn't agree more. Anyone remember the Mercedes' Boxfish design? I seem to remember reading they wouldn't build it because it was (paraphrasing) too ugly. I think if they can sell the Smart car, they could sell a Boxfish.


The boxfish prototype has a drag coefficient of .19! If Mercedes was too scared to build it, they should've given, or at least offered to license the design to Smart.

Id buy a boxfish design .. i dont think its ugly.. looks like cash in my pocket from gas savings... if it were low cost and efficient.. build it for the price of a accent gets 50mpg.. they would sell like hotcakes.. hell looks better than a prius to me..

The prototype didn't get 50mpg... it was closer to 75 (combined).
