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…
> 1 protein plus 1 electron Assuming that was autocorrupt. :) But 1+1... isn't that just normal hydrogen? Is the point that it's atomic, not H2?
I wish I could blame autocorrect. Just had proteins on the brain and typed the wrong word. If it wasn't obvious,
protein --> proton
Couple of quotes from the OP: "To produce hydrogen, water (H2O) can be converted into hydrogen gas (H2) by means of a series of chemical processes. However, as water molecules are very stable, splitting them into hydrogen and oxygen presents a big challenge to chemists. For it to succeed at all, the water first has to be activated using a catalyst – then it reacts more easily. A team of researchers led by Prof. Armid…
On a tangential note, how do you pronounce the second researcher's name? Zhang as to my knowledge is pronounced with a distinct "Jha" aspirated sound, correct? Back to the article though, from what I understand, the alkenes and arenes merely act as the catalyst for the reactions, so the article calling them the equivalent of hydrogenation reactions seems incorrect. Perhaps, a more equivalent term would be temporary h…
It's the retroflex version of "Zang", where the "z" is sort of like a "t" followed by an "s" sound. "Retroflex" means that the tongue bends a little bit backwards and therefore touches the palate a little bit farther back. Don't sweat it too much, for most people the whole series of s/sh, z/zh, c/ch, and x/j/q are hard to consistently get right unless they are corrected by a teacher. Also, since romanized Chinese names usually lack tone marks, some ambiguity regarding the correct pronunciation remains.
To do this, what level of distillation needs to be reached? When breaking the bonds in a water molecule, what happens to the impurities in the water?
"the opposite". You need mildly polluted water to make it easier to split molecules (pure water requires way more energy to split apart). In this paper, they specifically want the impurities to accept the hydrogen.

interesting. so can you split water to make hydrogen && desalinate would be the direction of questioning in my mind
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...
Maybe we need mini packblimps that can not only carry fuel, but part of the pack, the dog, the kid, etc. It could have AI assisted propeller machetes to hack away at wayward branches, geofenced to protect endangered flora of course. Then if you add some condensing coils and a transparent roof, you could also just leave the backpacking food in there and it'll slowly get moist and solar cook. After a twelve hour hike y…
would this not be considered a drone? drones are not legal in national parks. can only imagine each state following suit for state parks.

Guess we have to get rid of the props and just tether it to the pack like a balloon.
Seriously though, I've often wondered if a weather balloon style lifter tethered to a backpack could help it be lighter. Probably with a less flammable gas, and only in sparsely forested areas.
Where do you find 550g lighters? Surely a pocket lighter to save half a kilogram of water is worth it
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
The way I was picturing it, you light the balloon and, besides some burn marks and a boom heard miles away, water appears in its place and falls into a bucket you placed below.
Not like I know how this stuff works. Someone says methane turns into water when burned, I imagine based on farts that it floats like in a nice balloon or Hindenburg, I figure this do be how this was intended ¯\_(:))_/¯

Less flammable would be Helium. It just so happens that the US is looking to sell the strategic helium reserve. So you just need to find a VC and you can get your backpacker's assistant idea off the ground. hehe
as far as helium balloon, it would have to be a balloon of such enormous size to be of any benefit. To launch a couple pounds of payload to 90k feet required a balloon 8' in diameter on the ground.

A kilogram of lift per cubic meter of helium.
At sea level; if you let it expand it only goes bigger at altitude, without needing more helium.
> 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
Liquid methane can use normal thermos technology, with the venting fed through a burner to create your water.
