Algae's solar electrons hijacked to steal power 2

An international gang of biologists has carried out an audacious heist, stealing valuable electrons from photosynthesising algae.

The power grab could open a route to more efficient exploitation of photosynthesis to power machines: with biofuels we are already converting solar power into a form that engines can use, but almost three-quarters of the sunlight energy absorbed by the organisms is lost before it can be turned into the sugars or starches used to make biofuels.

Grabbing photosynthetic energy earlier in the process should allow much more to be extracted, says WonHyoung Ryu at Yonsei University in Seoul, South Korea. "Theoretically we should be able to collect all photosynthetic electrons."

    Ha, ha! That's an interesting way to communicate that they are trying to capture more energy for useful purposes

    Photosynthesis : a new source of electrical energy
    CNRS scientists have transformed the chemical energy generated by photosynthesis into electrical energy. They thus propose a new strategy to convert solar energy into electrical energy in an environmentally-friendly and renewable manner. The biofuel cell thus developed could also have medical applications. These findings have just been published in the journal Analytical Chemistry.
