Most people would agree that fossil fuels should no longer be an irreplaceable part of humanity's main sources of energy. They contribute to environmental pollution, changes in climate, numerous economic conflicts.
Because of this, the search for alternative energy sources has intensified over the years, with some of these sources being quite strange.
Believe it or not, body heat can also be used as a source of energy. This would be one free and effective way of energy transfer. The mayor of London adds that the excess heat produced by people in the subway tunnels can be redirected toward the very homes of the British.
Another interesting and practically stupendous way of producing alternative energy is to use sugar. Chemist researchers from Virginia Tech are working on a way to turn sugar into hydrogen. This way sugar can become a driving force of engines, to yield a cleaner and odorless fuel.
The use of solar radiation is another innovative approach, which would assure 100 billion times more energy than humanity needs at the moment. It comes from solar wind, as well as from the stream of charged particles from the sun.
The use of human or animal feces is a way of harnessing energy that has been studied for a long time. They contain methane which can easily be used for energy flow. The same applies for urine, which is rich in urea, and it - in nitrogen.
Another remarkable, yet expensive, renewable energy source is vibrations. It has been found that using piezoelectricity technology for obtaining energy from the vibrations of people who walk, dance, etc, may one day be of great use.
The use of glow-in-the-dark jellyfish hides a strange potential for energy production. They glow thanks to the proteins found in their bodies.
There are also 3 lakes known for their vast reservoirs of methane and carbon dioxide; they are called "exploding lakes".
Certain bacteria, like the well familiar E. coli contains a fuel, stored in the form of fatty acids. Scientists are working on creating a genetically modified bacteria that can produce massive amounts of these valuable fatty acids.
