MIT scientist develops artificial solar cell leaf that can power a house for a day with a single gallon of water
by Jonathan Benson (NaturalNews) A scientist from the Massachusetts Institute of Technology (MIT) says he has successfully developed a type of synthetic leaf made largely of silicon and electronic components that is ten times more effective at photosynthesis than is a natural leaf. And this artificial leaf, he says, is capable of generating enough electricity with one gallon of water to power a house in a developing country for an entire day.

Daniel Nocera recently told attendees at the National Meeting of the American Chemical Society in California that when his prototype leaf is placed in a pool of water, it effectively captures sunlight and splits water into oxygen and hydrogen at ten times the rate of a natural leaf. Operating for at least a full 45 straight hours without any decline in performance, the leaf acts as a small, highly-efficient solar cell that produces energy for use in power generation.
"The artificial leaf shows particular promise as an inexpensive source of electricity for homes of the poor in developing countries," said Nocera in a statement. "Our goal is to make each home its own power station. One can envision villages in India and Africa not long from now purchasing an affordable basic power system based on this technology."
Reports indicate that Nocera has already made a deal with the Tata Group of India to develop a small power plant that uses the technology to distribute electricity. Within a year and a half, the power plant, which is roughly the size of a refrigerator, is set to be completed and ready to go.
Similar projects in the past that involved synthetic leaves have not been as successful as Nocera's endeavor. A Wired report explains that John Turner from the US National Renewable Energy Laboratory tried to build a synthetic leaf more than a decade ago. Unlike Nocera's inexpensive leaf technology, Turner's leaf used expensive and rare metals, and it did not even last a day before degrading and losing its viability.
what a wondrous vision! love it. It's so clear to me that we have everything we need to build a golden age on this planet.
All that's 'sketchy' is the commitment to peace. I have a lot of faith in the good, just hope I get to stay around long enough to see it prevail.
A wondrous vision and a fools folly!
I gotta admit it sounds pretty far-fetched. But didn't the horse and buggy crowd once say the same thing about the automobile? Who knows what the future may bring - almost certainly not centuries more of the same old fossil fuel technology. Course that firewood was awfully useful this past cold and icy winter . . . (and it felt good to know that I was helping global warming along).
If history tells us anything it is that our government trying to provide just about anything for us will manage to turn it into folly no matter whether an idea was viable or not in the beginning.
The MIT guy's idea is to produce home sized units. I would be a possible buyer if not for all the trees my house is nestled in - and you know how much I like to hug them.
