Engineers Use Rocket Science for Self-Sufficient Wastewater Treatment

Photo via divemasterking2000 Nitrates are commonly found in groundwater, ending up there after they’re used for fertilizing crops or from storm-water run-off. Typically a contaminate to worry about, a group of engineers from Stanford University have figured out how to turn the problem of nitrates in the water in to a possible solution for energy generation. While their design started out as a nitrous oxide thruster for spacecraft, they figured out how it could also be used at wastewater treatment plants to turn decompose nitrous oxide gas into… Read the full story on TreeHugger

Biochar Reduces Nitrous Oxide Emissions From Soil by Three Quarters: Study

photo: Stefano Mortellaro via flickr Biochar proponents now have an additional benefit to tout, in addition to increasing crop yields and carbon storage of soil: According to a long-term study in Australia, biochar both reduces nitrous oxide emissions from soil by 73%, and reduces inorganic nitrogen runoff from fields by up to 94%. … Read the full story on TreeHugger

Smart Grid + Demand Response = Underrated Renewable Energy Storage?

Photo: Flickr , CC Shaping Demand to Match Supply Serious discussions about renewable energy usually end up being about energy storage too. Wind and solar power are both intermittent sources of electricity, so if we want to power a significant fraction of our power grids with them, we need a way to store power for windless and cloudy days. The most talked about candidates are batteries, molten salts, pumping water uphill, compressed air, etc. All of this has to do with supply, but what about demand? “Demand response” is very u… Read the full story on TreeHugger

Maldives President scubas To stop global warming

A fitting place for the nation most at risk of being wiped out by rising seas to sign an historic SOS for climate change. COP15 is probably the most important summit ever and what was done today in the Maldives is not just a stunt, it is a reality that will not go away unless we act now to reduce greenhouse gasses like nitrous oxide and carbon dioxide. added by: southrabbit 1 comment
