you laugh but i've always thought it would be great to carry a kilo of pure hydrogen in my backpack - just burn it to obtain like 5 litres of water ... I mean why are we carrying all that oxygen in our backpacks when he atmosphere has a plentiful supply of it...

Have you ever actually seen a canister of hydrogen? Specifically, have you ever felt the weight of that canister? I'd rather just carry the 8lbs of a gallon of water. At least it gets lighter as the water is depleted

Just put the hydrogen in a balloon and it will carry itself.

Carbon is lighter than oxygen, so their plan would work if they brought fully saturated hydrocarbons including ones so long-chain that they were solid at room temperature.

What do you expect to do, open the valve, flick a Bic, and the water is going to start flowing? Come on. This was a fun nonsensical thread, and you're now trying to turn it into a magic trick rather than goofy science. You have to capture the flame's exhaust, pressurize it, and whatever other sciencey stuff to get the waste into a liquid

> pressurize it You "just" have to capture and cool it down. I mean, it's completely outside of viability, but it's not breaking ground science. You could do it perfectly well in a lab (if you had any reason to).

There's a lot of things that can be done in a lab, but bringing it to the real world is totally different. Nevermind fitting this in the original concept of backpacking

Just remember, the flame from hydrogen is clear and very hard to see until it catches other things on fire. At that point, it's well past too late

How much of a progress is this? Anyone here that can add insights?

The paper isn't about splitting water to yield hydrogen and oxygen gas which would be useful for energy applications. It's about a new way to make radical hydrogen (1 protein plus 1 electron) which is useful for synthesizing some organic compounds. It will be helpful for synthetic chemists and will make it easier to explore hydrogen radical chemistry. It may replace some processes that currently require transition me…

Anything that creates hydrogen radicals could conceivably be used to construct electricity-producing fuel cells.

Fuel cells normally radicalize hydrogen by contacting hydrogen with platinum catalysts under extreme conditions, requiring expensive and tricky design.

If this new process can do the same in mild conditions with inexpensive organic catalysts under exposure to light, it could lead to more economical fuel cell designs.

Just need a longer string for the balloon and it'll be ok. And hike in places with less trees (although, after a few mishaps, the trails you frequent will have less trees, too).
