46,000 Square Miles of Forest Needed For 120 New US Wood-Fired Power Plants

published August 3, 2010 and has No Comments

Southern pine wood chips, photo: USDA Southern Research Station . Biomass burning for electricity still looks to be a political and environmental black hole, presenting more dreadful questions than a tree hugger can shake a blog at: Why, for example, are 120 new wood burning power plants being planned in multiple US states? Are banks and managing utilities planning ...

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 ...

Algae Biofuel Grown in Bioreactors Has 3.7x the Carbon Footprint of Petro-Diesel: Study

published July 30, 2010 and has No Comments

photo: jurveston via flickr Algae biofuels are probably the most touted future hope to replace large amounts of petroleum-based liquid fuels with a renewable source. However, a new study in Energy and Fuels shows that when you grow that algae in bioreactors made up of clear tubes, so much energy is required that the carbon footprint of the biofuel ...

900 Foot Offshore Wind Turbine Mimics Spinning Sycamore Seeds (Video)

published July 30, 2010 and has No Comments

Image via Dezeen The mantra of offshore wind turbine design seems to be "Bigger! Bigger!" in order to get more power out of single turbines. But going hand in hand with making turbines bigger is that they become heavier. British engineers are hoping that a new design that mimics the way sycamore seeds spin through the air will help ...
