That was on myth busters, (my 10 year old is a myth busters fanatic) according to their results, it actually decreased efficiency slightly
Really? I watch that show too, haven't seen that one. Are you in the UK or US? I saw the one where they tried various ways of killing an old V8. What else was in that episode?
...at best the energy required to burn it would be greater than the energy produced by burning it.
Therein lies the problem. You can generate energy in loads of ways, but most require using more energy than you get back. Otherwise perpetual motion machines would solve all our problems!
I'm in favor of nuclear power for everything.
Suits me. But I think Russia should look for other ways! ;)
It was an episode from 2006 - Exploding Pants. They were busting a bunch of ways to increase your mileage, it ended up with them running a diesel car on old fry oil from a restaurant. (it got decent mileage, within 10% of regular diesel fuel and all they had to do was filter it)
The energy cost of lighting salt water is more than what it produces.
Instead, the tiny piece of info in the news release everyone should be concentrating on, is Sterling engine, or external combustion engine...

Don't think I remember exploding pants.
Yeah I've seen that done on a show here called Top Gear. They diluted it slightly with white spirit and the car ran virtually identically.
Diesel's will run on pretty much any oil, my cousin runs his car on used engine oil when he does an oil change! I wouldn't do that though, I told him it'll knacker his injectors!
Realbrisk thanks for the link, but it just tells me I'm not in the US so I can't watch it!
or external combustion engine
I invented one once, although the insurance company kept telling me it just exploded! ;)
Salt water + metal engine = rust...
salt water + aluminium (or stainless steel, etc...) = lump of metal in water
Stainless steel is stain-less, not stain-proof, and given the conditions inside the engine, won't last long before breaking. Aluminum has a melting point too low to handle engine combustion.
Can it be done? Probably. Will consumers save money by getting free gas and paying six figures for a car? Probably not...
Say what? World Products' all-aluminum Motown small-block is the "low carb" alternative [superchevy.com] All that's needed is a corrosion resistant cylinder liner. A titanium suboxide should work.
