In Cambridge has developed a super-efficient fuel cells from algae

Plants on planet Earth millions of years to convert water and sunlight into energy, which is used for their needs – scientists have something to learn from them. But sooner or later it’s time to move on, and researchers from Cambridge have developed a new design of fuel element based on algae. They focused on minimizing losses during the transfer of energy from the cell to the consumer.

Algae do not produce electricity, it is formed as a byproduct. In the process of photosynthesis and the formation of new chemical bonds in a living cell creates a certain amount of free electrons. Some of them moved beyond it – if you take this process under control, it is possible to obtain the movement of electrons or electric current. This technology is called “biophotonik”.

In Cambridge decided that if we divide the region where photosynthesis occurs and where there is a “pumping” of electrons, they can improve each of them separately. And create a fundamentally different working conditions for photosynthesis needs constant access to light, but the electric highway should be isolated as carefully as possible, avoid losses.

Along the way, was the testing of a new variety of GMO algae in which the electrons are generated in photosynthesis is more intense. The result was a new design of fuel cells, five times more productive than the previous version. And it is 0.5 W from 1 sq. m., and the “green battery” live long and in addition can replicate.
