an article about a company that actually does something useful, I cant believe my eyes.

Kind of ironic coming from the CEO of a social networking website.

Chris Stewart - not just any social network. One of the fastest growing social networks in the world.It helps you connect and share things with friends. Moooove over facebook. Innovation is here.

Should make long term space travel a reality.Will certainly assist settlements on Mars.
As an Australian, I delight in Americas continued ability to innovate, thus confounding its domestic critics and foreign adversaries. Go USA.

I hadn't thought about that, it's essentially compressed breathable air (or rather you can refresh breathable air with the O2) and fuel... though water is incompressible, it's probably still a fairly efficient way to store it. And it's reusable. The efficiency still has a ways to go, though.
Also i just realized the numbers are superscript instead of subscript in the article, i'll fix that later.

Devin Coldewey you can't refresh breathable air, because 2H20-> 02 + 2 H2, but humans exhale Co2.
Nevertheless a great sucess, thumbs up for the MIT.

Since it makes Oxygen from water without using electricity, you could incorporate this into some sort of underwater suit that wouldn't require oxygen tanks and you would be able to be underwater for unlimited amounts of time. Or submarines would be able to get both oxygen and fuel from just being underwater.

a suit maybe seems unlikely but submarines, sure! that have order of magnitudes larger surface area compared to a human body.

There is absolutely nothing unique about a photochemical cell that electrolyzes hydrogen and oxygen from water. It's been done dozens of times. The only unique aspect of this is that Nocera claims he has developed a catalyst that is cheap to the point where this might be economically feasible as a fuel generation device. As with all early stage science, the economics have very little clarity right now. So he might be right and he might be wrong about the cost of the thing. If he is right, then he has to prove the durability of the device. Many catalysts break down in weeks or months, but this would need to last for 20 years on your roof. If he proves that it's durable, then he has to increase the efficiency. Why would you put a chip on your roof that is 6% efficient when you can put a relatively cheap chip on your roof today (i.e. a PV panel) that is 18% efficient? Nocera has a long way to go before this becomes a viable product.

Calling this an artificial leaf feels misleading. Unless it can actually couple carbon dioxide fixation with electrolysis, (literally the reverse of burning gasoline), it's just a photo-voltaic tied to electrolysis cell. Not that this isn't awesome.

greed, not *exactly* a leaf but awesome as hell anyways :D Although it would have been even more cool if it actually took in CO2 and gave out O2. a proper leaf.

Achin Sharma We already have those though. They're called leaves :)
btw, slightly more on topic, I wonder if these can work off of heat? What is the energy activation range? See: the difference between thermoelectrics and PV's

Fascinating. A self-sustaining and enclosed system of energy conversion. This would definitely open up possibilities for colonizing on remote bodies in space, or getting there at the very least for exploratory purposes.

I was wondering if we get the same effect if we'd immerse solarcells in water with their terminals connected to conducting and transparent material?
