Ok well Not completely True;
I came accross this a few years back.
It's Claimed You can reduce Fuel Consumption by up to 50%, You'll still need to fill up with normal fuel, be it Petrol, Diesel or LPG/Natural Gas etc...
You need to
Buy or
Build a Browns Gas Generator, Feed the resulting Fluid into your engine or fuel tank, and hey presto, you've got a car that has better mileage per gallon consumption.
Nowadays For $750 you can buy the kit From
Here.
A Few Years Back These Generators were costing $US 5K +.
I haven't got the technical ability to build the damn thing otherwise I would have, I know what Browns Gas is, It's been around for almost a century, I don't want to buy the generators cos they are so expensive even at $750, I've seen people using the kits but I don't know them personally, hell there's even a garage that does the installations here in the UK now, the installation could invalidate your car warranty, so this would be great on an old Car.
God only knows what this will do to the engine after a few 1000 miles, the heat generated must be enourmous, as Browns Gas was developed for Welding and Cutting Metals.
If any of you ever get to do it let us know here plz
peace out
