The Water Engine. Toyotas and Tesla's new hydrogen system that makes EV's old technology

Oh. Well that works if they’re offloading it away from the ICE.

I was just going to thank you for that article. That explained it. I just see one issue. You can’t just convert a full tank of water into hydrogen. I’m sure these guys are smart, and will be able to figure out how to do it slowly. But it does bring up some safety concerns.

not sure if they’re using the oxygen in the cumbustion chamber or just using air to mix. I think, though am not certain, it gets recombined in the exhaust and forced into the chamber by a turbo. not sure though.

One thing I read said temp was maintained at 6500c because of the Hydrogen and it has some sort of water cooling in the cylinders themselves. Not sure if that was true, and not sure how it would work, or how you’d keep paint on the hood. I’m thinking it was a typo and should have been 650c

Also 6500 degrees would require some fairly exotic block and head material. Even Top Fuel funny car engines don’t run that hot and they are using pure methanol as fuel and run no cooling system in the block.

I don’t get it. Where does the energy come from to separate the hydrogen and the oxygen, and why don’t they just use that power source to directly run the motor?

because the objective is to have water as a fuel thereby solving recharging problem, battery weight, rare earth metals, and hydrogen refueling stations.

It takes energy to split the water between oxygen and hydrogen. Again, where does that energy come from?
Hmmm,…checking YouTube, it looks like hydrogen gas and oxygen are pumped into the car and the water is created from those gases and their stored energy released at that point. Water is the byproduct.

no, thats not the way this one works. They’ve had hydrogen engines before. They require hydrogen refueling stations and high pressure tanks. This is not one of those

since it takes electricity, probably a battery, just like it does to start your car now. Then the alternator takes over

I think the articles are confusing some different things

oh well… may not be what the article suggests

Laws of Conservation of Energy would take over.

You can’t have an engine produce enough energy to create its own fuel. It breaks the laws of physics. It would be like making a dam that could pump the water from its base to fill itself. Hydrogen generation on the fly won’t work unless it’s something other than the engine supplying the power to split the molecules.

Yes, the hydrogen will be combusted, and water vapor will be the exhaust. Vapor, not liters of liquid water. :wink:

Electricity/magnetism, and a catalyst. I’ve demonstrated it by using muriatic acid as the catalyst. Toyota is certainly using something better. lol

Re-combining it is as easy as lighting a match, or a spark of electricity.

If we are talking about the Marai engine, it does indeed use a high pressure hydrogen tank for fuel.

we are not, that is a fuel cell engine, not a combustion engine. Although I could be wrong about the Marai, the articles are not real clear

The Marai is only available in California where they have hydrogen fuel stations.

I got really excited thinking these were actual water engines at first. :rofl:

If you turn water to hydrogen, doesn’t it take up a lot more space? How will they do that? How do you account for the extra space?

do any of you actually read the links?

Yes, Toyota now has a water engine, it is not in production yet.

Yes, Toyota also has the Marai, which is not a water engine.

according to the articles it converts small amounts to hydrogen on the fly for use. It does not convert an entire tank of water into hydrogen at one time
