New algae fuel cell packs a punch

New algae fuel cell packs a punch

A new algae-based fuel cell developed by the University of Cambridge is five times more efficient than existing devices. Researchers have long looked to algae as a power source because of its efficiency in turning sunlight into energy. This new technology, called a biophotovoltaic, is able to harvest the energy in sunlight to produce electricity like a synthetic solar cell, but using organic materials. The basis of the new technology is a genetically-modified algae that carries mutations that lower the amount of electric charge released nonproductively during photosynthesis, so less was going to waste. The other major change was building a two chamber system for the device. The two chambers separate the two processes of generation of electrons through photosynthesis and the conversion of those electrons to electricity, which in previous devices has be done in a single unit...
