[PhysOrg] 'Artificial leaf' moves closer to reality

post #1 of 9

An important step toward realizing the dream of an inexpensive and simple "artificial leaf," a device to harness solar energy by splitting water molecules, has been accomplished by two separate teams of researchers at MIT. Both teams produced devices that combine a standard silicon solar cell with a catalyst developed three years ago by professor Daniel Nocera. When submerged in water and exposed to sunlight, the devices cause bubbles of oxygen to separate out of the water.

even as a kid i always though this would one day be possible... lets hope its efficient enough to be applied to something beneficial and not simply toyed with in labs or class rooms.

This has already been posted...a while back I believe.

Let's talk about it again anyway.

I want in, either way. They don't know until they see the proof. If it's 0 point, well, you'd know, yourself.

The advanced class of photonics and photovoltaic cellular structure headway in the past has only been a concept of sand, spark, and solar capture, nothing more. When you can composite a material that acts organically, you forego any possibility of lacking the retainer, as inclusion by instructing the cells is cohesive and chemical at the same time, you can't have more than two at a time with photovoltaic, or you risk a high amount of radiation poisoning of both paneling AND UV. The pledge. But how do you gain more electric capacity? By colliding instead of lacing, OR, build a latch within the cellular format with piezometric scaling, essentially scalar capture. Within tolerance of the two, are a hard coded matrix, and the actual values of each vault and hemisphere of the skinlike resinance latticed between the mixtures and compounds. Adding the photovoltaic compound creates what? Light composition electron vacuum when used with an electromechanical inductive inversion field. Using a helix bond, which isn't unfathomable, but adding hexaquantitative proportions to it, as if using hexadecimal form coding, instead, when using collision and bond between elements, once fused, becomes entirely organically weaved, celluloid one, a cluster electrostatically photostatic charged cells, with one new organic goal: Photovoltaic synthesis.

Hopefully a compound helix can be run to sustain it.

what part of your childhood got you all pumped up about futuristic artificial photosynthesis?

What? We have oceans of the stuff. Fresh water, in many places, is in short supply, sure.
When you burn H2, you get water. I'd imagine all the hydrogen burnt would become water again maybe?

New water is made all the time. Albeit at a slow rate.

We would have to be burning a hell of lot of it for a hell of long time to even put a dent in the oceans though...and I mean a dent as in lowering sea level even a nocitable amount. I'd be more worried about global cool down by emitting too much oxygen into the air

Yes, Mint is correct. If you used this with a fuel cell system, you'd be taking the hydrogen you've created and you'd be combining it with oxygen to create, wait for it...water! And it'd be fairly pure at that. The issue isn't water, it's the environmental cost of the catalysts required for both this 'leaf', and a fuel cell system.

lmao, you put it in such a sarcastic manner its great!

No seriously, I remember watching all those TLC and Discovery shows and sit in science class being fed info on how stuff works and then when you're exposed to scifi films and games and see cool tech and wonder how that stuff worked...
Always wondered about making something like a tree out of synthetics(playing 'god' in a sense) day dreaming about stuff that didn't exist back then but theoretical could...personally as an 8 year old i tried to solve the world energy problems with magnets and demolished electronic toys...
