Synthesize power from trees

The University and the Wageningen Research Center (NL) have developed a technology that allows the conversion of wetlands (which account for 6% of the Earth's area) into a useful renewable energy source. Scientists believe that their new technology could be used to provide electricity to remote areas.

Unlike biogas (generated by fermenting biological wastes), an integrated system called the Plant-Microbial Fuel Cell generates electricity without compromising on growth or harm. to the habitat of trees. This system utilizes up to 70% of organic material produced through photosynthesis. These are substances that trees do not use and are discharged to the soil through the roots. These wastes are broken up by natural bacteria in the soil and release waste products by means of electrons. By placing an electrode close to the bacteria that act to absorb the electrons, the team can generate electricity.

Plant-Microbial technology Though Fuel Cell is currently only 0.4 Watt / ^m2 of land covered with trees, but experts assert this way still more power synthetic production of biofuel source plant and animal origin (biomass - rice husk, sawdust, wood chips, straw, animal dung ...). They also believe in the future, this system can be improved when the synthetic power with a capacity of about 3.2 Watt / m ^2, ie a roof area of 100m ² can wooded Provide enough power for a family with an average power consumption of 2.800 kWh per year.
