Michael Grätzel, however, may have a clever way to turn Nocera's discovery to practical use. A professor of chemistry and chemical engineering at the École Polytechnique Fédérale in Lausanne, Switzerland, he was one of the first people Nocera told about his new catalyst. "He was so excited," Grätzel says. "He took me to a restaurant and bought a tremendously expensive bottle of wine."

In 1991, Grätzel invented a promising new type of solar cell. It uses a dye containing ruthenium, which acts much like the chlorophyll in a plant, absorbing light and releasing electrons. In ­Grätzel's solar cell, however, the electrons don't set off a water-splitting reaction. Instead, they're collected by a film of titanium dioxide and directed through an external circuit, generating electricity. Grätzel now thinks that he can integrate his solar cell and ­Nocera's catalyst into a single device that captures the energy from sunlight and uses it to split water.

An interesting article about the drama of producing clean energy.

this is why all Americans who can so afford should all buy all american, MADE, GROWN AND PROCESSED IN THE UNITED STATES cotton clothes. If the Victoria's Sercret chinese formaldehyde rashes are not enough of a sign that we have the ideas - they steal them and sell a warped brown market version of same, and then poison us.
Wake up. Look for the 100% US COTTON label.
