Japanese Company Says Laws of Physics Don't Apply — to Cars 736
Fantastic Lad, among many others, points out another in a long series of claimed "powered by water" cars, this one by a Japanese company called "Genepax," which interestingly enough does not have so much as a Wikipedia entry. What's scary is the uncritical, even serious-sounding, presentation by Reuters of such extraordinary claims quite unbacked by extraordinary evidence. "Almost sounds too good to be true" isn't the half of it; if cars could be made which would run as "long as you have a bottle of water inside" to pour into the fuel tank ("even tea," repeats this report), not only would you know about the car, but you'd notice the long lines of people buying generators, laptops, and power tools that run on the same technology. The snippet Reuters is carrying says "Jun. 13 — Japanese company Genepax presents its eco-friendly car that runs on nothing but water. The car has an energy generator that extracts hydrogen from water that is poured into the car's tank. The generator then releases electrons that produce electric power to run the car. Genepax, the company that invented the technology, aims to collaborate with Japanese manufacturers to mass produce it." Fantastic Lad, deadpan, goes on: "Check out the Reuter's story and accompanying video. Now, correct me if I'm wrong, but isn't there some sort of conservation of energy thing happening in the whole 'separating hydrogen from water' game? I wonder what the real story is on this. Investment fraud? Magic?" Show your work; bonus points if you use Haiku.

The problem is that when you "use" hydrogen to create electricity, the hydrogen recombines with oxygen to become water once again. So let me use some fictional numbers here to demonstrate why your suggestion is impossible:
1. Assume it takes 1 joule of energy to split a water molecule.
2. Assume you get back 2 joules of energy when you "use" the hydrogen.
3. You now have the same water molecule you started with, and a surplus of 1 joule of energy.
Where did that energy come from? It'd be one hell of a magic trick if you could pull it off! That's why no process which splits water will ever generate more energy than it consumes.
Yes, but when you split an atom you're actually destroying that atom. Once the process is complete you don't have the same atom you started with - instead the atom is gone, and you have a surplus of energy.
And for the other type of nuclear reaction - fusion - you actually fuse two hydrogen atoms into one helium atom, so you end up with a different form of matter than what you started with. THAT is where the energy comes from.
See the difference?

A guy that went by Teilhard de Chardin, long ago, said something to the effect of "in the cosmos, only the fantastic has a chance of being real."
Given that everything we once took to be science fiction or "tools of the devil" are now things we take for granted every day, perhaps the idea that energy is easier to extract than we've been taught by our establishment, may well not be as "unpossible" as we've been taught to believe. Frankly, I've seen entirely too many things in my life to think that its all as simple and cut and dry as school would have us believe.

Mod this man up. If I was a Japanese guy who discovered some "free-energy-from-water" process, I wouldn't be using it to merely power a car. Japan doesn't have any native oil production at all. Hint, they started the Asian portion of World War II because the USA embargoed oil exports to Japan due to atrocities like http://en.wikipedia.org/wiki/Nanking_Massacre [wikipedia.org] "The Rape of Nanking". Due to the embargo, Japan was looking at totally running out of oil by the end of 1942. Civilians would starve, as would the occupation army in China, and their vaunted military machine would grind to a halt and collapse. Japan had a choice between pulling out of China and grovelling before the USA, or else militarily capture oil-producing territories. Guess which they chose?
Japan would dearly love to have "free-energy-from-water". Due to their annual oil bills, they would greatly benefit from something like this device. But rather than merely putting it in cars, they'd scale them up into large electrical powerplants that would run their cities. The Japanese desparation accounts for the fact that Japan is the last country where serious research into cold fusion is going on http://newenergytimes.com/news/2008/29img/Arata-Demo.htm [newenergytimes.com]. Cold fusion, BTW, is the only conceivable form of free-energy-from-water that doesn't break the known laws of physics, but implementation is the problem. The fact that the company is hawking a consumer product to the man on the street, rather than a big power plant to government, is what pegs my bogo-meter.

Water injection isn't about putting water in the gas. It's about injecting water into the combustion chamber which regulates and slows the burning. Also the expanding steam helps extract just a bit more mechanical energy out of the heat from the combustion. I'd say the reason it's not mainstream is because we've already improved efficiencies a lot using other, easier methods. Modern engines are already doing other things to regulate combustion (fuel injection and fuel stratification, multiple ignitions per cycle, etc) that the benefit just doesn't make it worth their while. Consider that modern IC engines with the improvements I've mentioned are much more efficient and powerful than ever before. However our cars are heavier now, offsetting a lot of those gains. If we'd stick our modern engines and transmissions in the cars (hopefully not as ugly!) of the 70s, 50 MPG would be routine on highways. Anyway now that the low-hanging fruit has largely been picked, what we have left are more complicated things like water injection to try out. One problem water injection always had, besides the complication of pumping and injecting, was rust.
But don't discount it completely! You're right to suspect any dramatic claims. I'm thinking 10-20% improvement is all any one technology could possibly bring. But don't forget that at less than 18% mechanical efficiency from an IC engine, there's *lots* of room for improvement. Lots of efficiency improvement is somehow still possible. Obviously claiming to surpass 100% efficiency is BS!
One exciting thing being tried right now on big diesel engines is hydrogen injection. It's looking like it improves efficiency quite a bit (as much as 10%) while reducing emissions dramatically, which more than covers the energy needed to split water to get it on the fly. A 5-10% improvement in fuel economy on a truck is huge. Can equal savings of thousands of gallons of fuel a year. Of course the proponents of this technology note that efficiency improvements are much less on modern engines that already control combustion much better than they used to. But there still are some benifits (at least a few percent!) as well as major decreases in particulate and NOx emissions.

So let's calculate how fast you'll receive a fatal dose of radiation. Let's assume the fatal dose to be 10 grays - that's 1000 joules of whole-body absorbed energy for 100kg of body weight.
Even aneutronic boron-proton fusion produces 0.1% energy in form of neutrons. Let's assume that 1% of these neutrons reaches you.
So you'll absorb 0.01% of engine's power in form of penetrating radiation. Let's assume that engine's power is 100hp, that's 75kWt in SI. So the neutron flux through your body will be about 7.5 Watts.
So you'll get the fatal dose in about 2 minutes.
Have a nice ride!

Truth is what you want it to be.
Adding a certain % of water might work if it helps improve internal combustion efficiency. Current internal combustion engines waste approx 80% of the energy and some of that might be recovered.
Some use a small amount of water plus a shitload of electricity to do electrolysis. They're as dumb as the "I get 200mpg with my hybrid" claims where electricity is the primary power source.
And the rest??? Well until you see independent evidence they're probably all hoaxes.

If it's real, every scientist will then nod and go "Yup, they're right".
Scientists really don't give a crap about people's crackpot theories unless they *are* going to affect the known laws of science. That's where science gets interesting. Did you know, for example, that there are quantum effects that "get" energy from nowhere and then "return" it later in time. They literally "borrow" energy from the future. Muc

2) Separating hydrogen from water is NOT breaking any form of phsyics. The question would be the chemical/energy cost to do it.
For something to think getting hydrogen out of water is UBER crazy talk, doesn't realize that the laser printer on their desk is creating ozone by the electrical charges bouncing ox
