Toyota water engine

[Robert]

Basically a hydrogen engine but modified to overcome the problems with storing hydrogen. So it makes it on board. If Toyota can keep this going it will change the auto industry and most industries in the US. Oil, Electric, China, Russian, Iran,South American, Saudis will all go down in flames if mass produced.

  About 8 to 10 years ago I was on a tech site.  Tesla had a semi-truck running on water hydrogen. I contacted my broker asking him to check on stock. Long search turned up no stocks available.  There were supposed to be 7 to 10 trucks running out of California for testing. Most of what I tried to follow seemed to vanish from public eye.
  I wonder what the residue (have not checked before I replied) will be after removing the hydrogen .
 Have we created a new waste. What happens in cold weather. ???

It’s going sub zero this weekend in Minnesota. In the video they didn’t address how the water storage system is kept from freezing. On top of that , anyone noticed the sharp rise in their water bills over the last few years? Making distilled water at home is not free. Cost of water and the energy to produce. With the water shortage in the western states I’m afraid you would, sorry for the pun, have a cascade effect on water supply. We will never receive the full picture of a project from the greenies.

After reading about this several weeks ago, I was wondering if there was a lag time between when you got into the vehicle, and it had hydrogen to start the engine?  Did it store a bit to let the vehicle to start when you first want to start it?  Hadn't thought about the cold weather and water issue.  Also, hadn't thought about the problem of water itself.  If one would use tap water, what happens to the minerals in the water.  Or is pure H20 needed.  if the later really expensive.

just another pie in the sky dream. without the billions in free fed tax dollars, actually corporate welfare, given out by bush jr there wouldn't be any hydrogen engines.

There is a lot of talk about the oceans levels rising. Use some of that clean, free solar or wind power to de-salt ocean water for the vehicles. Win win win for everyone.

Mazda was the only one that truly made the Wankle or Rotary engine work. They spent the time and money and made it work with so much against it.

I have learned to respect the Japanese and their technical prowess to produce good quality and usable products that work well.

Honda made our bikes, make jet airplanes, lawnmowers  and it seems most anything they set their mind and hand to come out good.

So while all these are good points, I have seen much harder obstacles overcome in the examples I gave. The engineering to make the Rotary work was astounding.

I am encouraged that the current crop of electric vehicles will eventually die off or wait till the time and technology is right to produce a car that truly works with peoples lives. The mining of the minerals for electric cars destroys the planet.

A hydrogen powered car could smooth the transition between electrics and gas also.

EVs are already dying off esp in the used car market, nobody is buying them.

the most efficient is a narrow rpm range small diesel engine driving a generator that drives electric motors at the wheels. Chrysler used their full size car as prototype with the driveline back during Clinton's 2nd term and was getting 70-80 mpg on the hwy.  govt and P.T.Bs didn't like that kind of efficiency so it went away.

The diesel  VW's were amazing at mileage, power and lack of repair. You know they had to do something to also take these off the market since they were very popular.  I agree on the diesels, Europe uses them why not the USA.

I see a number of practical issues with the concept.

From a science and physics perspective, yes, it is doable.

But, you can't use any old tap water. You'd have to use a high quality distilled water or have an onboard system to purify it. The infrastructure to do this isn't available.

And you'd need significant amounts of energy to distill the amounts of water needed to supply the new fleet of water powered autos.

Fuel storage (water) would be an issue in cold climates. Perhaps some concoction of anti-freeze and water would work. I don't know. I'm not a chemist.

And what would the cost of such purified water be? This would increase the demand for this kind of water.

And if the process to separate Hydrogen from Oxygen from water was economical, we'd have a hydrogen based infrastructure now. We don't. So something is holding it back. My guess is that the hurdles are just too expensive to overcome.

Still better than the EV path though.

I hope they find a way over the hurdles and they find a way to make it work.

Not going to hold my breath though. Well, if I'm under water I would.
