Salt Water: The Tangy Taste of Energy Freedom

Apr 16th, 2010 | By John Waller | Category: Biofuels, Top Story

A visitor to Eastern Europe after the fall of communism would have been awestruck by the massive posters touting Winston cigarettes as “the taste of freedom” that often plastered locations where posters of Chairman Stalin and his ilk has once fluttered. It looked as if Christo had wrapped the Iron Curtain in a project sponsored [...]

Scientists Harvest Electricity from Living Algae Cells

Apr 15th, 2010 | By John Waller | Category: Biofuels, Top Story

Stanford University scientists have created a tiny electrode that can harness an electric current from a single algae cell, a breakthrough they hope will one day lead to the creation of an inexpensive source of renewable energy. The nanoelectrode, made of gold and specifically designed to probe inside cells, is so sharp that it is [...]

New solar-cell efficiency record set

Mar 5th, 2010 | By John Waller | Category: Solar PV, Top Story

Here’s a seemingly simple solar power fact*: the sun bathes Earth with enough energy in one hour (4.3 x 1020 joules) to more than fill all of humanity’s present energy use in a year (4.1 x 1020 joules). So how to convert it? In the world of solar energy harvesting, there’s a constant battle between [...]

Saudi Arabia to Replace Oil with Sun Power for Desalination Plants

Feb 1st, 2010 | By John Waller | Category: Solar Thermal

You would imagine that a desert country like Saudi Arabia would have to rely a lot on desalination for a good part of the fresh water it uses. For example, a previous Green Prophet article told about the Kingdom building what they say is the world’s largest desalination plant  in the Al Jubail Industrial Zone [...]
