Major Discovery from MIT

I was just thinking about how high the gas prices were and how dependent America is on foreign oil and just oil in general, we depend on it to do just about everything for us and most in our minds is that we depend on it to take us back and forth to work. Having said this always in the back of our minds we are hoping that scientists can find something useful and is safe to the environment around us,because our kids and grand kids have to live in this world to. This discovery could transform solar power to a more mainstream alternative to our problems of energy,when we think of solar power naturally we think of the sun and hey the sun has to shine for this energy to even register with us,but what if we could store the extra solar energy for later use? Yes,this got my attention what if it could be stored for later use. Excerpt from article;

Inspired by the photosynthesis performed by plants, Nocera and Matthew Kanan, a postdoctoral fellow in Nocera's lab, have developed an unprecedented process that will allow the sun's energy to be used to split water into hydrogen and oxygen gases. Later, the oxygen and hydrogen may be recombined inside a fuel cell, creating carbon-free electricity to power your house or your electric car, day or night.

The key component in Nocera and Kanan's new process is a new catalyst that produces oxygen gas from water; another catalyst produces valuable hydrogen gas. The new catalyst consists of cobalt metal, phosphate and an electrode, placed in water. When electricity -- whether from a photovoltaic cell, a wind turbine or any other source -- runs through the electrode, the cobalt and phosphate form a thin film on the electrode, and oxygen gas is produced.

Combined with another catalyst, such as platinum, that can produce hydrogen gas from water, the system can duplicate the water splitting reaction that occurs during photosynthesis.

The new catalyst works at room temperature, in neutral pH water, and it's easy to set up, Nocera said. "That's why I know this is going to work. It's so easy to implement," he said.
