After Sergei's post regarding electric cars.. I had a look at this too. Read a fair bit about it on the internet.. figured I'd have a nudge.
I hooked up dads' battery charger to 4 stainless plates arranged as per pics I found on the internet, stuck them in a sealed glass jar with water and a splash of white vinegar, fired it up.. and much to my surprise, I got bubbles.
This is the interesting part.. I pulled the lawnmower over, disconnected the fuel line, ran it still it died. Hooked up the pipe to the air cleaner, gave it a couple of hearty pulls, got it to "chug" over a couple of times, but then it backfired through the pipe and split both jars, lol.

According to the charger, I was pulling about an amp and a half at 12 volts.
There is no magic to this, no bullsh*t, its' just simple electrolytic process, the same thing that goes on inside any lead/acid car battery, but on a larger scale. I had the idea that all these internet people selling these "run your car on water" machines were just a bunch of conartists, maybe they are, but the idea they're promoting isn't that unrealistic.. its' just that we've got a long, long way to go before this could even remotely considered a viable stand-alone fuel source.
Thoughts?
