Artificial Inorganic Leaf (AIL)

http://www.mnn.com/green-tech/gadgets-electronics/blogs/titanium-leaves-could-unlock-hydrogen-power
Quote:

If you want to impress your friends with a little-known but totally epic acronym it is "AIL" the Artificial Inorganic Leaf. This week, thousands of scientists descended upon San Francisco for the 239th National Meeting of the American Chemical Society, and one of the papers they heard was on AIL technology presented by a research team from the Shanghai Jiaotong University in China.

Using sunlight to split water into its components -- hydrogen and oxygen -- is one of the most promising methods for creating a sustainable, safe and cheap alternative to fossil fuels. And there is no machine more efficient at using sunlight than the humble leaf. Through photosynthesis, leaves use the power of sunlight to assemble sugars using only carbon dioxide, oxygen and water.

Creating an Artificial Leaf

http://www.thirteen.org/curious/survival/creating-an-artificial-leaf/17/
(article has very nice video)

Quote:
Spurred by the looming energy crisis, Nathan Lewis and Sossina Haile are working to invent a new kind of fuel that uses the sun to power the planet. They are attempting to produce a prototype for a truly alternative fuel source — an artificial leaf that emulates natural photosynthesis, converting solar energy into a usable, clean chemical fuel. They hope their pioneering solar cell and fuel cell technologies will eventually end our dependence on petroleum and provide an energy source that won’t pollute our planet.

Device creates fuel from sunlight

Quote:
U.S. and Swiss researchers say they've developed a solar device that can turn the energy of the sun into fuel.

The apparatus focuses the sun's rays onto a metal oxide called ceria to break down water into hydrogen.

Tata to Fund MIT Professor's Solar Technology Research

Quote:
Speaking yesterday at a press conference convened by the Chemical Research Society of India in Bangalore, scientist C N R Rao said Tata has given $15 million to fund the ongoing research that is being conducted by MIT professor Daniel Nocera.

Nocera, listed in 2009 by Time Magazine as one of the world's 100 most influential people, has found a sustainable and clean way to use the sun's energy to split water molecules into hydrogen and oxygen gas, which can be stored and recombined in a fuel cell to get carbon-free electricity that can be used in homes as well as electric cars.

<b>Artificial Leaf Could Be More Efficient Than the Real Thing</b>

Quote:
Speaking at the National Meeting of the American Chemical Society in California, MIT professor Daniel Nocera claims to have created an artificial leaf made from stable and inexpensive materials that mimics nature’s photosynthesis process.

The device is an advanced solar cell, no bigger than a typical playing card, which is left floating in a pool of water.

[...]

With a single gallon of water, Nocera says, the chip could produce enough electricity to power a house in a developing country for an entire day.

'Solar fuel' research mimics photosynthesis

Quote:
The center is one of many so-called solar fuels efforts that seek to bypass the traditional biofuel method of growing plants and then convert biomass to a transportable, liquid fuel. Other researchers and companies are seeking to genetically engineer microbes that secrete fuels or develop cheaper methods for splitting water to make hydrogen fuel.

Nanotrees harvest the sun's energy to turn water into hydrogen fuel

Quote:
University of California, San Diego electrical engineers are building a forest of tiny nanowire trees in order to cleanly capture solar energy without using fossil fuels and harvest it for hydrogen fuel generation. Reporting in the journal Nanoscale, the team said nanowires, which are made from abundant natural materials like silicon and zinc oxide, also offer a cheap way to deliver hydrogen fuel on a mass scale.

Quote:
The first practical artificial leaf, composed of silicon, nickel and cobalt, can convert sunlight into chemical fuel, a milestone in the drive for sustainable energy that mimics the process of photosynthesis.

Unlike earlier devices, which used costly ingredients, the MIT-developed artificial leaf is made from inexpensive materials and employs low-cost engineering and manufacturing processes.

HyperSolar Envisions Solar Powered Hydrogen “Farms”

Quote:
Hypersolar’s system goes even farther down the size spectrum, using tiny particles consisting of a nanoscale solar device and a protective plastic coating.

The particles float in water, and the coating enables them to function in hostile environments including sea water, wastewater or stormwater runoff. That gives the system a leg up on conventional hydrogen systems, which require purified water.

The reaction takes place at ambient temperatures, so it can take place in a low-cost glass vessel or even an ordinary plastic bag.
