Y'all are a bunch of wankers!

Interesting. I wonder what will happen when one of them crash?

An earth-shattering Kaboom.

Kinda like happens when you collision a fully charged electric car -- those Lithium batteries burn until consumed -- water just makes them angry.

Fuel cells don't explode. It's not the same as burning from a tank of pure H2 like with a spaceship.

> in favor of batteries

Hydrogen fuel cells are a type of battery. It requires a lot of energy to make the cell, the energy is then released by the device it powers.

Consider nickel-cadmium batteries. We could call them nickel-cadmium fuel cells and it would be the same usage.

Sure.  I was kidding.

Nonsense, the possible I/O for a battery is electricity, not a fuel.

It's not the fuel cell you need to worry about, it's the hydrogen tanks at 500+ bar..

But hydrogen is not quite as dangerous as people think and gasoline is more dangerous, we're just used to it being around.

The Hindenberg didn't explode, The gasoline depot at Buncefield went up like a fuel-air bomb.

And Myth-Busters demonstrated it was coated in a mixture of Aluminum and Iron-Oxide, otherwise known as 'Thermite'.

Hydrogen burns with an almost invisible blue flame.  The Hindenberg didn't burn blue.  Though all the pictures originally were black-and-white, so if the colorist got it wrong, so it goes.

Even so, the black-and-white flames were WAY more obvious than a hydrogen flame would have been.  It was the thermite.
