Mimicking Photosynthesis To Split Water

plantsdoitsocanwe writes "An international team of researchers led by Monash University has used chemicals found in plants to replicate a key process in photosynthesis, paving the way to a new approach that uses sunlight to split water into hydrogen and oxygen. The breakthrough could revolutionize the renewable energy industry by making hydrogen — touted as the clean, green fuel of the future — cheaper and easier to produce on a commercial scale." This was a laboratory demonstration only and the researchers say they need to bring up the efficiency.

There have been numerous such laboratory demonstrations on different ways to produce hydrogen easily. But the attempts to bring up efficiency are just what failed.

I don't think so, although I initially thought the same thing.

The MIT process (from July 31 /.):
"..catalyst is made from cobalt, phosphate and an electrode that produces oxygen from water by using 90 percent less electricity than current methods, which use the costly metal platinum."

The Monash team (todays /.):
"..using just sunlight, an electrical potential of 1.2 volts and the very chemical that nature has selected for this purpose". The chemical seems to be "a form of manganese".

They are not claiming a breakthrough in energy production, they claim to have made a breakthrough in artificial photosynthisis, no small feat IMHO. Also the CSIRO are not in the habit of making unsubstantiated claims and their evidence has been published in a peer-reviewed journal.

It's pretty obvious you are looking for a different breakthrough and it's a certainty you won't find it if you are unwilling to entertain NEW knowledge that MAY be relevant.
