[phys.org] Air, water and sun: The ingredients of 'green gasoline'

post #1 of 8
Thread Starter 
Quote:
(Phys.org) —Mimicking a natural process perfected over billions of years to capture solar energy, researchers are creating artificial photosynthetic systems that will turn air and water into transport fuel.
Quote:
"The process we are developing is sustainable because it uses sunlight-driven water splitting and takes carbon from the atmosphere only to return it when the syngas is used for the release of energy."
Quote:
Photosystem II (PSII) is a plant protein that captures photons of light and uses them to energise electrons and oxidise water to produce O2. The researchers have now integrated this protein in a synthetic system to extract electrons to produce H2. "What we are creating is an artificial metabolic pathway – one that wouldn't conventionally occur in nature. By combining our synthetic version of PSII and a synthetic hydrogenase, the former captures light energy and feeds electrons to the latter."

I can't get enough of this bioindustry.

Oil industry, conspiracy, Illuminati, etc.

Putting that aside this is mind blowing. I hope that I can live into my old age to see this technology brought into fruition among other forms of alternative energy.

It's only a matter of time. Technology can only progress forward but corruption is holding us back.

Real questions for the viability of this technology: how efficient is this compared to other current methods of creating hydrogen from solar energy? And how does this compare to other biofuels?

Spot on. Efficiency is the key. This type of technology won't be viable for another decade at least, in my opinion. But we are on the right track to a more efficient fuel.
Off topic, all we need now is talk of creating water on a more safe and viable scale and I will be very happy with technology.

Right now I'm more interested in the engineering of "artificial metabolic pathways." That being said, so far the use of these biologically-derived processes has often shown to require much less energy input than the chemical or other conventional industrial processes they are emulating.
