Hydrogen is a lousy motor fuel because it migrates through everything and has a low energy density even when liquified or highly compressed. I would prefer to use liquid ammonia as a fuel.

Slowburn - Haven't you heard that graphene is completely impervious to any type of gas? so solutions are possible. If you think that this new idea to harvest H2 is not noteworthy and that you'd prefer to use liquid ammonia, just go out there and get it done yourself!

The water level is rising and the forests are shrinking. Theese things...i don't know if ere good.

Slowburn. What a delicious non sequitur. You are very handsome.

Hydrogen Fuel Cells produce electricity ... why on earth would you burn it?

I'm always happy in advances like these but I'd be happier if any of this stuff actually made it out of the Lab- not that it never happens- the super strong, scratch resistant glass used in Iphones and the like was invented by Corning in a Lab- in the 60s

The scratch resistant screen!?! You do realize that every single component in the iPhone was in the lab at some point, a lot of it more recently than the 1960's. These projects almost always go somewhere, when they don't lead to directly marketable applications the lessons learned serve a useful purpose in another lab.
This work is brilliant!
Jeff- One of the main reasons you may want to burn it instead of feed it to a fuel cell is because sometimes the transition to electrical potential is just to slow for the application. There are also tech reasons. Example: You can feed an unlimited supply of H2 into a fuel cell indefinitely but even all of that electrical energy isn't going to put a rocket into space without a magnetic linear accelerator or some similar intermediary that doesn't currently exist. Burning a Hydrogen based fuel can.
There are a lot of reasons to burn it.

Hydrogen Fuel Cells produce electricity by burning it in a very controlled manner. Besides an ICE engine costs less and has a longer life expectancy. .............................................................................................................................

Please demonstrate a tank that is sealed by a single sheet of graphene without joints, and a valve that seals as well for hydrogen as I can expect for ammonia.

They shouldn't sit on this until it fits their own definition of "perfect." If it can really create hydrogen as efficiently and inexpensively as they claim and this can be mass produced, they should begin releasing this for sale to companies now. Then later, once they've fixed the degradation issue and found a way to efficiently absorb carbon dioxide, release "nanotree 2.0" and continue from there.
Don't sit on this "nanotree 1.0 just because you don't have the new and improved version ready yet. Bring it to market and then make it even better for future versions, just like every other product on the market.

Interesting:) I thought Hydrogen engins at the end of the day, is more about zero emissions, not how it is made or pedantic lab work. And ammonia made on a scale to power and replace the car, sounds like that idea should be on the back burner not the slow burner:)
