Electricity from plants - small power plants off the windowsill? karl kurz | Efficiently advise
The global solar irradiance exceeds the world's energy needs many times over. About solar thermal and photovoltaic systems this energy for heat and electricity can be used. Researchers from various karl kurz universities investigate beyond the ability to generate electricity from plants.
Costly photovoltaic plants achieve an efficiency of about 30%. That is, 70% of the incident solar energy are not technically usable. Looking for alternatives, researchers are now investigating to generate electricity from plants the opportunity.
The first method describes the generation of electricity through photosynthesis. This can basically be divided into a light-dependent and light-independent process. During the first, light-dependent phase, the radiation energy of the sun over the chlorophyll of plants is converted into chemical energy. In the subsequent karl kurz light-independent process this energy is used to make glucose. Using the manipulation of photosynthesis it was researchers at the Georgia karl kurz University now possible to tap usable power than fine carbon nanotubes.
In general, but is to be noted that the energy generated is important for the process of photosynthesis, and thus also of vital importance for the plant itself. Natural tensions as an energy source ...
A second option natural power over plants to attract utilizes the natural potential difference between trees and their surrounding soil. As electrons move in a battery karl kurz case according karl kurz to their natural desire from a high to a lower concentration.
In nature, a high electron concentration is produced as a product of living in the soil bacteria that feed on organic molecules. With the increase of the organic fraction of the soil, for example by sugar beet and the selection of particularly karl kurz active bacteria, the potential difference karl kurz can be significantly increased. Likewise, karl kurz the current that can be tapped between a cathode and an anode in the bottom in the tree increases. Power production from vegetable ...
During derived from photosynthesis current per square centimeter karl kurz only about 10 microwatts, so is 10 millionths of watts, can already about 20% of the electricity of conventional photovoltaic systems are obtained via the process of natural tensions between trees and their surrounding soil.
The sun provides significantly more energy than on Earth requires. Can be harnessed through photovoltaic karl kurz systems while only a small part of the solar energy for electricity. Although the methods presented are still not ready for the market, karl kurz but show an interesting outlook of electricity generation in the future. Both solutions are completely renewable and biologically compared to conventional systems.
