2. ?

Cars are just one use for hydrogen.

Drones, trains, trucks, forklifts, bikes, ships, submarines...

all fueled by hydrogen NOW

Soon: cell phones, laptops, and more

It's the next big thing

4. How do you contain high pressure gas state hydrogen to use for power?

This has been the problem in hydrogen powered vehicles for a very long time.

Hint, before you reply you need to know your physics, chemistry, and atomic structures.

Hydrogen is a very small atom and it is extremely hard to contain in a gas form under pressure. It tends to go through the containment vessel as if it were a sieve.

Hydrogen is most usually contained, stored, and transported in liquid form. To be useful in vehicles it has to be in a gas form and pressurized.

So, what are your ideas?

5. There are MULTIPLE EXAMPLES

How do you think they are containing H2 on this drone?

Did you miss the carbon fiber tank?

How do you think H2 is contained in the 4 Hydrogen cars now on the roads?

How do you think H2 is contained in the >15,000 Hydrogen powered forklifts operating NOW?

How do you think H2 is contained in Germany's Hydrogen submarine?

How do you think H2 is contained in the 2 Hydrogen trains running NOW in Germany?

6. Totally useless video, tank wasn't filled w/700 bar of hydrogen & no ignition source was nearby.....

7. There's "Useless" in this thread

but it is not that video

WTF is your problem anyway?

Maybe you just can't understand H2 tech.

Who cares.

There are 8 billion people in the world

Some of them think that the US could go to the moon (using hydrogen fuel cells!) but can't figure out how to store hydrogen.

Endless entertainment- thanks for that

9. That was my question to you, not if they are doing it but how they are doing it.

You failed to answer that question.
