I looked at several threads about using browns gas as a supplement to give a car better gas mileage but it seems no sure yes or no to this mileage booster was given. The Internet is full of adds to use browns gas generated on board you car as you drive to give huge mileage boosts. To me it looks a lot like perpetual motion.
I’ve seen these, too. Nearly all of them appear sensational, pseudo-scientific, and designed to defraud scientifically poorly educated people out of money for videos, plans, and equipment to add worthless equipment to their cars. I’ve read several testimonials from people who claim a modest improvement in their cars’ fuel economy, which I suspect is due to a combination of not wanting to feel silly about wasting money, labor, and possibly damaging their cars, wishful thinking, outright lying, and real improvements in fuel efficiency due to simply driving slower and more smoothly, maintaining proper tire pressure, etc.
Has any definitive answers been found for this?
I’d say the definitive answer is well known – you can’t get more energy reacting hydrogen and oxygen to form
, whether by combustion of something like a fuel cell, than was used to disassociate the
into hydrogen and oxygen, whether via electrolysis, steam reforming, or other means – as you, Moontanman, have done a good job of pointing out in this thread.
Brown’s gas, according to its wikipedia article, is just oxyhydrogen
a mixture (rather than the usual compound, water) of hydrogen and oxygen gas, usually in the usual 2:1 ratio. His main interest was in using it as a welding – it’s hotter than oxy-acetylene, but cooler than a couple of other welding gas flames. Electric arc welders have since taken over the welding biz, as they’re hotter than the hottest gas flames, and don’t yuck-up the metal with a reactive gas. I get the impression oxyhydrogen torches are still popular for cutting and polishing glass.
Last Xmass, I got a little toy oxyhydrogen generator that shoots a little rocket a hundred feet or so into the air
. It runs nicely on 6 D-cell batteries (9 V in series), though it has annoying built-in soundtrack of bubbling noise, random science facts, and a claxon after a fixed time interval warning you not to shoot yourself when you press the igniter button, and for reasons I’m unable to guess, barely works under about 10-15 C outdoor temp. :shrug:
Steven Harris seems to the main proponent of this idea, he has impressive credentials, is he on the up and up?
I’d not heard of Roy McAlister and Steven Harris before this thread, but they do seem at first glance to be pretty credible, if obviously pros interested in selling videos and books, not giving out info gratis. As best I can tell, they specialize in describe practical engineering details of making and storing hydrogen, burning it in engines or using it in fuel cells. I’ve seen nothing connecting McAlister and Harris to any Brown’s gas fringe theory/conspiracy theory/run-you-car-on-water scam, though some of these folk into these appear to know about them, and reference them in their fringy/conspiratory/scammish writing.
