Brazilian builds water-powered motorbike

[Uncle Joe]

He claims it can go up to approximately 310 miles on 1 liter of water.

1. That was pretty good. A strong rival for the Air Car.

2. Do believe he's a fake? nt

[immoderate]

3. Unless they repeal laws of energy, I surely do.

4. I know some basics about the laws of energy but

it's not my area of expertise, what in particular contradicts this?

[immoderate]

5. Well, it takes energy to electrolyze the water. From where?

What makes the current? You can't get back more energy than you put in.

6. There isn't anything disputable in the physics, this is just economics...

In Brazil petroleum probably costs a lot more than household electricity, so he is able to convert a small amount of water to hydrogen using household electricity, enough to power a small motorcycle. On a larger scale though, the costs don't balance.

[Uncle Joe]

7. So would increased solar and wind power used to convert water to hydrogen

be more economically feasible on a larger scale?

[rwsanders]

13. that is one possibility that has been considered.

Then it can be burned or used in fuel cells (use the reaction with oxygen to create electricity directly).
The only other way to use wind and solar are better batteries. So it is hard to know which will win in the end.

8. It shows him filling is tank from a stream. What household electricity?

It is a fake. I'm disputing the physics. It's bullshit. You can't create energy from the air.

9. He is also using a battery.

It's pretty clear that he developed a rudimentary oxyhydrogen generator (which isn't new). He is very clearly producing hydrogen gas at the end of the video in the dish. None of this is new or groundbreaking, and it's going to be less efficient than using the electricity in the first place.

[immoderate]

10. He's not going 200 miles on a battery.

And he not getting 200 miles worth of hydrogen from the battery.

11. With the small size of his engine, he probably does not need that much hydrogen to

run his engine. He would not be able to run a car with it. One thing is those small motorcycles used to be the ones that created a lot of pollution so it is a viable solution.

[rwsanders]

12. I think that was just showmanship as he mentions converting to hydrogen. No other way...

to do that without outside energy unless he has a miracle catalyst.

[immoderate]

14. And with no place to store it?
