Water-powered car?

Is this for real?

Real or no, it's fun to think about.

lol Man, I love that show.  Don't recall ever seeing the pilot though.  Funny as hell.

Re: Water-powered car?

It's just splitting h2 and o2 from water, then burning them to weld stuff.

And the car is just adding h2 in to the gas mix instead of gas i'd bet.

The problem with this is that you'd spend a LOT more money and time using electricity to split water to store as hydrogen, to lost a lot of efficiency, when you could just use gasoline.

Water is a significantly less dense energy medium than gasoline, so there is literally no way it could be more efficient than gasoline. There are other hydrocarbons that would be acceptable for on-demand h2 creation for usage as a fuel, if we could perfect catalytic h2 extractors.

Re: Water-powered car?

You seem to know more about this than I do, but in the second video, they mentioned that the Aquygen powered car improved gas mileage by up to 50%.  I take this to mean mean the whole vehicle is powered entirely by gasoline and H2O (i.e. the Aquygen machine is powered by the car's electrical system), with the net result being a 50% improvement in fuel economy.

This is actually a very old video, and the ins and outs are easily available all over the web.

It's probably somewhat accurate that there is a 50% improvement in gas mileage, but how does that help you when you're spending more than the 50% cost of gas to charge the batteries to power the electrolysis process?

Re: Water-powered car?

OK, I found the company website.  The Electrolysis system in the test vehicle was powered by the car's beefed-up alternator.  The fuel economy went from 33.0 to 40.56.  The third test was run with the system on, but the gas was vented; this gave 29.3.  I think the third test is supposed to measure the amount of gas needed to power the system.

But anyway, this isn't as cool as I initially thought.  I don't know how much the unit is, but I doubt it will justify the improvement in gas mileage.  It's not nearly as cool as running your diesel car off free recycled french fry grease.

Re: Water-powered car?

Ah, this thing!  I remember going to an information meeting held at a hotel.  They were trying to sell their hydrogen system to transport truck fleet operators for a pittance, then raking in carbon credits at the expense of the Kyoto protocol. 

By the end of the ridiculous pseudo-science ridden powerpoint presentation, it had "new energy" wackos chomping at the bit, and anyone with formal scientific or engineering education ready to bolt.  It was hilarious to sit back and watch, as conversation at the end of the meeting degenerated into the ability of oxygen to eliminate free radicals in the body to cure cancer, perpetual motion machines, and all manner of other armchair scientist wet dreams.

The best part is, they didn't even have a working prototype to show us.  I know, I asked.  What a waste of time that was.

Re: Water-powered car?

There is all kinds of this stuff all over the net right now.  A lot of people have tried a lot of different configurations on a lot of different cars and gotten a lot of different results.  I don't know why anyone would pay very much to buy one of these "systems" though. Anyone with a basic level of scientific knowhow, and reasonable amount of creativity could build their own system for far less than what some scammer would charge. It would just take time and careful planning.

Re: Water-powered car?

I too think this is a cool concept, but see the flaws being pointed out. If only we had a way to cheaply (in terms of energy input) split the H from the O in water.  Cold fusion anyone?

That is the ultimate dream - just put water in your tank, and go.  But you need something like cold fusion or an amazingly efficient solar panel to invest the energy to split up the water molecule.

Re: Water-powered car?

A guy I work with rigged up a hydrogen generator in his car and claims 24% greater gas mileage.

But, if you've managed to perfect cold fusion or have a powerful enough solar cell to run electrolysis, why not cut out the "middleman" and run the car directly from the electrical input? You always lose energy when you change it from one form to another (inefficiency lost to heat), so the fewer transitions, the simpler the engine, the better the energy efficiency.

Systems like this one are usually complex rather than simple—and not because complex makes for better science, but rather because the complexity serves as a screen behind which to deceive the audience.
