Making Hydrogen from Plants

Scientists in biological systems engineering at Virginia Tech have succeed in using xylose, a sugar found in plants to produce large quantities of hydrogen in an environmentally friendly way. 

Unlike current methods of making hydrogen gas, Associate Professor Percival Zhang’s process is done at low temperatures, uses no heavy metals and releases almost no green house gases.  His team designed an enzyme cocktail for splitting of the hydrogen.  The result is energy production at a rate of more than 100% efficiency; a level current methods do not reach.

Anti-Nuclear Demonstration in Richmond

On the two-year anniversary of the Fukushima nuclear accident in Japan, anti-nuclear demonstrators rallied outside the Richmond headquarters of Dominion Virginia Power. 

The protestors say the Fukushima experience shows that the risk of disaster at nuclear facilities is far too great to keep operating them.  They’re calling on Dominion to close its North Anna and Surry nuclear power stations—and instead use wind, solar, and other renewable resources.

The Fukushima site is still so radioactive that it will be eight years before the melted nuclear fuel can be removed.
