Could Small Springs Beat Batteries?

MIT scientists have found that carbon nanotubes could be formed into tiny springs capable of storing as much energy, pound for pound, as the best lithium-ion batteries - potentially more durably and reliably.

Reducing the Cost of Energy in Concentrated Solar Power Systems

Concentrated solar power (CSP) and concentrated photovoltaic (CPV) methodologies generate electricity by focusing a large amount of sunlight onto a much smaller area. To maximize efficiency, the sunlight needs to be accurately focused, and the accuracy is limited by the accuracy of the sensors used. A white paper from US Digital discusses why an absolute inclinometer is the most effective sensor solution.

Algae Blooms Broaden Battery Possibilities

Blooms of Cladophora algae may be troublesome, but they do have a positive side. Researchers at the Ångström Laboratory of Sweden's Uppsala University have discovered that the cellulose nanostructure of these algae can serve as an effective coating substrate for use in environmentally friendly batteries.

Tree Totally Powers Custom Circuit

Last year, MIT researchers found that plants generate a voltage of up to 200 millivolts when one electrode is placed in a plant and the other in the surrounding soil. A University of Washington team followed up on this research, and has run a custom circuit entirely off tree power.
