In addition to my own work, you will find a list of resources with external links and recommended readings.
| 29/03/11 "Nearly all the energy we use on this planet starts out as sunlight
that plants use to knit chemical bonds. Now, for the first time,
researchers at the Massachusetts Institute of Technology have created a potentially cheap, practical artificial leaf
that does much the same thing—providing a vast source of energy that's
easy to tap. The new device is a silicon wafer about the shape and size
of a playing card coated on either side with two different catalysts.
The silicon absorbs sunlight and passes that energy to the catalysts to
split water into molecules of hydrogen and oxygen. Hydrogen is a fuel
that can be either burned or used in a fuel cell to create electricity,
reforming water in either case. This means that in theory, anyone with
access to water can use it to create a cheap, clean, and available
source of fuel." |
