Nov November 19, 2008 | 15 Comments Torrefaction is a thermo-chemical treatment of biomass in the 200 to 340 degrees Celsius range. In this process the biomass partly (especially the hemi-cellulose) decomposes, giving off various types of volatiles. The remaining torrefied biomass (solid) has approximately 30% more energy content per unit of mass.

Annually, photosynthesis is said to store 5-8 times more energy in biomass than humanity currently consumes from all sources. Biomass is currently the fourth largest energy source in the world – primarily used in less developed countries and could in principle become one of the main energy sources in the developed world. Higher temperature gasification of biomass began in about 1800 and by about 1850 gas lighting for streets was commonplace. With long experience with biomass gasifiers, reliable and large-scale operations continue to suffer from several problems.

(x) German student builds electromagnetic harvester to recharge a battery. Dennis Siegel, a student at the University of the Arts in Bremen, Germany has built what he calls an electromagnetic harvester—it converts electromagnetic fields in the immediate environment into electricity to recharge a common AA battery.

He's won a 2nd place award in the HfK Bremen Hochschulpreis 2013 competition for Digitale Medien, for his efforts. Electromagnetism is all around us of course. In addition to natural sources, such as lightning, it's also given off by virtually every electronic gadget, device or machine humans make. Siegel (and many others) have noted that the electromagnetism around us all could be converted to electricity and used for some purpose.

The particulars of the electronics inside his device haven't been detailed (likely to prevent copycats) with a description only of "coils and high frequency diodes" being put to use to allow for the conversion. Explore further: Going nuts? Untitled.
