|Thoris||Wow scott that was a cool read, i am looking foward to more infomation about other fuel sources.|

Yeah read up on him man. Tesla, the dude had it all figured out. He even started to build a free energy machine in NY. Then they discredited him, bankrupted him, and eventually had him whacked! ha
I think I heard about the methane thing too. Apparently there's tons of it dissoved in the oceans. They are actually worried about it releasing into the atmosphere because methane is like 20x more potent a greenhouse gas than CO2. There is a lake in Africa, I forget the name but it is saturated with dissolved co2. Once in the 80's something released all the co2 at once and it killed 1000s of people nearby. If we could get the methane out of the ocean maybe we would be averting a natural disaster as well!
Although methane is a hydrocarbon so burning it is going to produce co2 no matter what. It's basically natural gas, still alot cleaner than gasoline. Even squeaky clean hydrogen - if it's burned in a pure oxygen atmosphere produces nothing but water vapor, but for real world uses burning it in regular air creates oxides of nitrogen from the nitrogen in the air and other impurities.
Moral of the story, burning anything is bad in the long term. We gotta put our thinking caps on and get way out past that for the future.

Careful! watch your back with that kinda talk...Nikola Tesla!
I figured you would pick up on that. I thought you posted once about being an engineering student. And I have read things that say the conservation of energy law seems to have problems when you look at the universe as a whole. So who knows?
I agree hybrids are just a temporary pacifier. Electric/fuel cell cars are probably the best bet long term right now. No batteries with their environmental problems, the energy is stored in nice, clean hydrogen. Just need to find a way to get that cleanly and efficiently.
That's where your free energy machine comes in

|Gustov||yeah, i actually had thought of that hvalley. i thought it was interesting that salt water ignited though. none of this is gonna matter soon though, i'm gonna discover a way to farm entropy, i think i'm getting close|

Interesting topic guys. Unfortunately things aren't quite as simple as that article makes it seem. I will guarantee that the energy used by his radio wave device is more than the energy available in the hydrogen produced. By the laws of thermodynamics it has to be, and they've held up pretty good for the last couple hundred years.
That would be called an "overunity" reaction. A type of perpetual motion. People sure have been looking, but no ones found one yet. Hydrogen is not an energy source, its an energy carrier. The energy used in splitting it from water is always more than what you get back. Even a unity reaction (1:1) is impossible. There is always a loss (entropy). This is true of any physical reaction.
What you need to look at is getting free, clean energy to obtain the hydrogen(solar, wind, etc.) Google solar electrolysis, it can be done pretty cheaply on a small scale. I think the Dutch actually have some solar powered hydrogen refueling stations for the public.
And if we're talking about automotive uses, since you've gone through all that trouble to get your hydrogen, you'll want to use it as efficiently as possible. The rotary is sure alot better than a piston engine but still internal combustion is not the way to go. Fuel cells use the reverse of the electrolysis reaction to produce electricity. There are electric motors that can approach 90% efficiency. You also get the benefit of dynamic braking where the kinetic energy of the moving car is reclaimed instead of just being wasted as heat (the current brake pad system).
I didn't put this here to shoot anyone down or anything. I think about this kind of stuff all the time too when I'm buying $4/gal gas! The best things happen when everyone is throwing out ideas.

Here is the link of Mazda's Rx-8 Hydro running with duel fuel system since 2004. They have been working on hydrogen since 1991.
Its in Japanese but it shows you how the hydro rotary works..'

|Thoris||the other thing is what about the fricken batterys that go in a few years. Of how much waste that will create, its almost as mad as using fossil fuels|

but I do think it's going toward the right direction, I mean come on if this guy can come up with this many other scientist can do it. I need to get to a laptop and I can show you guys a video on running a rotary rx-8 hydrogen car in japan. I honestly think hydro is the next fuel for the world. I really think hybrids are a fashion statement to say I care. Which in reality is as much of destrution of the enviormemt as using fossil fuels.
I will edit when I get to a laptop, I wrote this on my itouch
