- knightblade2oo4, on 10/12/2007, -3/+69I made a car that runs on momentum. You dont even turn it on. Tow it to the top of a hill, and give her a push... one push gets you all the way down the hill!
- Cander, on 10/12/2007, -1/+51"This inventor was later killed in 1998 obviously?"
obviously. Except for the story about his death is pretty silly and the story people put out about his death is different everytime someone tells it. - EochaidRiata, on 10/12/2007, -1/+51"breaks down water molecules into oxygen and hydrogen."
Where does the energy for this process come from? Magic?

I guess you never heard of a hydro-electric power plant? - Technopundit, on 10/12/2007, -2/+23Didn't Hyde talk about this several times on "That 70's Show"?
- DubbedOver, on 10/12/2007, -2/+20Why let a little thing like that stop you from breaking down water molecules?
- lordthor, on 10/12/2007, -6/+23lol jigga-WHATs?
"No! Gigawatts!"
Jigga, PLEASE. - chicken101, on 10/12/2007, -0/+15The enthalpy of water is -282kj/mol. That's the energy required to break one mole of water bonds. The bond energies for h2 and o2, combined, are less than that of water. Therefore, you need to put more energy into the reaction (2h2o ----> (electricity) o2 + 2h2), than you get out of it. Electrolysis is a 250 year old process, and every 20 years or so some nut job tries to fool the general public with their "water engine" designs.
Go read a science book, then maybe you won't fall for this crap next time. - merreborn, on 10/12/2007, -1/+15Exactly. "Water cars" are just hydrogen cars. And electrolosis is at best 50% efficient, meaning that you've LOST energy by the time you've broken your water down. There can never be a 'water car' that runs solely on water using electrolosis -- it will *always* require outside power.
Report this as lame. We don't want any more idiots getting their hopes up.
Rather than attribute the non-existance of 'water cars' to obvious physical impossibility, they attribute it to conspiracy. - creeptick, on 10/12/2007, -2/+12Buried as inaccurate: hoax. Been there done that.
- inactive, on 10/12/2007, -0/+9And what did you use to separate the hydrogen and oxygen? Did you use magic? Or did you use energy? I am betting on energy and a WHOLE lot of it!
- sakuraz, on 10/12/2007, -0/+9ok, at hydro plants, what's doing the job?
gravity? or water? - Cl1mh4224rd, on 10/12/2007, -2/+10"This would destroy the US Economy. It would put car dearships, repair shops, gas stations, oil companies, and car manufacturing companies out of buisness if everything he says is true. I can see why someone would want to kill him."
Gas stations and oil companies? Alright. But car dealerships, manufacturers, and repair shops? Could you possibly be anymore sensationalist?
Car dealerships: Somebody's got to sell the cars.
Car manufacturers: Somebody's got to build the cars for the dealerships to sell.
Car repair shops: Somebody's got to repair the cars sold by the dealerships which were built by the manufacturers.
I'm not exactly sure where you got the idea that these cars would just magically appear in peoples' driveways, that none of their parts would wear out... ever... or that they could either 1) never get in an accident, or 2) suffer no damage if they did.
Wow... - smoothdig, on 10/12/2007, -1/+10Why do you read and post then
- Lasker, on 10/12/2007, -0/+9chrisek is a digg spammer who gets tons of initial diggs from friends.
- Funkly, on 10/12/2007, -1/+9From wikipedia (not that thier always right, but this time it is)
The vehicle failed to work during a required demonstration of the water-fueled car in a 1990 court case. An Ohio court found Stanley Meyer guilty of "gross and egregious fraud" in a case brought against him by disgruntled investors. The court decided that the centerpiece of the car, his water fuel cell, was a conventional electrolysis device, and he was ordered to repay the investors $25,000.
word - Rostin, on 10/12/2007, -4/+11I call *****. The energy required to split a water molecule into hydrogen and oxygen is exactly the energy liberated when oxygen and hydrogen combust to form water. In other words, no net energy is released in this process. Since no real process is 100% efficient, he has to actually be adding energy some place to make this happen.
- happyfappy, on 10/12/2007, -1/+7This thing needs to be buried as inaccurate already.
- EGOvoruhk, on 10/12/2007, -5/+11Build one
- Funkly, on 10/12/2007, -0/+6damn your old.. wait *****.. it was 20 years ago for me to.. *****... i'm old
- Tenlow, on 10/12/2007, -4/+9Actually it was Gigawatts but the actors read it as Jigawatts and they liked the sound better.
- Chipsandsnacks, on 10/12/2007, -0/+5I have a go-cart that is powered by my own sense of self-satisfaction
- ryanst24, on 10/12/2007, -0/+5actually...the lone gunmen episode was much better than any mention from that 70's show
- InkTank, on 10/12/2007, -3/+8From: ConspiracyTheorist
interesting... - ArchieAndrews, on 10/12/2007, -0/+5Until you understand the point he was trying to make, it is best you stay out of this discussion.
- speaker219, on 10/12/2007, -3/+7Here is another video of water that powers a car (partially) it's a water/gas hybrid:
http://youtube.com/watch?v=J9iWaCMbw60 - elnerdo, on 10/12/2007, -12/+16I'm just going to say this right now:
Generating electricity from water, besides through a nuclear reaction is IMPOSSIBLE. It cannot be done.
Anyone who claims to have done it is lying. Most 'car that runs on water' stories are about a car that has a gas engine which runs a generator which splits water molecules and then puts the gasses through a fuel cell to generate electricity (Note, this is STUPID, because you're just wasting energy, as you can just use the electricity from the generator to power the car). - chicken101, on 10/12/2007, -0/+4But you need to put more energy (in the form of electricity) into it, then you get from burning the hydrogen gas at the end of the electrolysis process. So yes, the car will work, but you might as well just use a straight electric car, which is much more efficient that the electrolysis "model"..
Get my point? - MosaicM, on 10/12/2007, -2/+6omg! The world is flat, it's impossible to sail around the world! What are you, stupid?!
I've learned never to say impossible when dealing with science as most people in ages past have been proven very very wrong. - mathmanjeffy, on 10/12/2007, -0/+3News flash:
No serious medieval scientist actually thought the world was flat. That was all made up by renaissance thinkers to belittle their ancestors and increase the size of their scientific penis. - bneises, on 10/12/2007, -7/+10wasn't it Jigawatts??
- Poco, on 10/12/2007, -0/+3That's right, they drove it around and decided that society wasn't ready for such a car so they had to keep it a secret.
- gwolf, on 10/12/2007, -0/+3While this example is pure quackery; it makes one wonder why more research hasn’t been done in taking the things we have plenty of, Geo Thermal, Solar, Wave energy, water and using them to make the things we need, clean, cheap power. We are starting to get into wars fighting over resources, please waste some of my tax dollars on that research, please.
- elnerdo, on 10/12/2007, -1/+4Dolomite, Though the name 'hydro-electric' makes you think that water is actually generating electricity, you are only quasi-correct. Gravity drives the water. Saying that a hydro-electric plant is 'water-powered' is like saying that a coal plant is 'water powered' (coal plants use steam to turn turbines).
- whiskeymb, on 10/12/2007, -1/+3with the way the patent office works, I'm not surprised he has one.
- sven007, on 10/12/2007, -1/+3doesn't almost every method to generate power use water in some way? even the old coal plants still use in the states need water to make steam to turn the turbines. in every power source i know (except wind) water (or one of it's states aka steam) is used to turn a turbine, but the steam is made by heating the water, which is where the coal or nuclear radiation comes in.
- hovester, on 10/12/2007, -0/+2Fossil fuels are the way to go. I love my 18% efficient combustion engine. Just wish I had a "big ass" SUV. Thinking we can improve on this is a conspiracy in itself. Just hope the price of gas doesn't go up after the midterm elections.
- herculez, on 10/12/2007, -2/+4Did airlines destroy our economy by putting the railroads out of business? Sometimes industries become obsolete and become vulnerable to a shift in paradigm and disruptive technologies. It's high time for a radical change in the energy industry. The technologies exist, but the oil companies will do everything in their power to maintain the status quo, hurting the economy far more than they're helping.
- yasth, on 10/12/2007, -0/+2How about this, There is no standard chemical way to take water and gain electricity, Water is after all very happy being water.
There are mechanical ways (water wheel, depressurizing water) that use water as a conduit.
There are weird scary ways involving entropy (water is happy to stay water, but even the best relationships break up every once in a while, which if you can manage to remove one from the situation will allow you 2nd law safe system, though the doing is the hard part).
Truthfully when I saw the tile I thought someone was using over pressured water air mixture to power a car, which would have been a funny if pointless means of transportation, but still a good bit more feasible then this. - Noelix, on 10/12/2007, -0/+2Here's another water-powered car news segment that aired locally:

Aaaand that company's website: http://hytechapps.com/ - Cander, on 10/12/2007, -0/+2Wow I thought my post would get modded down hard as Digg seems to be over run by people who will believe anything they read on the net. Good to see critical thinking is still alive and well here.
But yeah this guy was con artist. Anyone who goes out and reads the stuff his believers always omit will see that.
And to touch on what I mentioned about his death. It was very cartoony the way it is told. It involves him either eating at a restaurant alone or toasting some people at a get together and some other variants depending on who tells it. Supposedly he suddenly jumps up immediatly after taking a bite (or sip), screams he has been poisoned, runs into the street, and drops dead. - Urusai, on 10/12/2007, -0/+2My water engine: wrap rope around axle, throw end up over a pulley high on the car, attach bucket, fill with water. Let bucket go, and zoom! You can even reuse the water!
- Apreche, on 10/12/2007, -2/+4Conspiracy people shut up. It's a hoax. Can't believe that news got fooled.
- ElectroBot, on 10/12/2007, -0/+2Go see the movie "Who Killed the Electric Car?"
A hydrogen fuel cell (when they begin selling commercially - 15-30 years?) will only be around 1/3 as efficient as a pure electric car.
Currently batteries are good enough that you could have an electric car that can travel 300 miles. And a full recharge can take as little as 4 hours.
If America really wants to reduce its dependancy on oil, they should create a electric-gas plug-in hybrid (with a focus on the electric). Use the electric engine most of the time and use the gas engine when the juice runs out, you need more acceleration or when its too cold to run the electric engine efficiently. - thepharmacist, on 10/12/2007, -1/+3Hehe
"It's a car, that runs on WATER man !" -Hyde
"So it is a boat ?" -Fez
Good times. - Shade00a00, on 10/12/2007, -1/+3For a second, I thought this was the car that would replace Jesus. Running on water is much more impressive than just walking!
- staydead, on 10/12/2007, -0/+2This is just Brown's Gas. You still need energy to seperate the water into it, and that energy is more than the energy you get from burning it, so you end up with a net negative energy..
So please explain how this can power a car.
The world waits. - Noelix, on 10/12/2007, -0/+2http://www.youtube.com/watch?v=4FBH4_FWBVA
