Scientists in Canada have used blue-green algae to energise a new kind of power cell that harnesses an electrical charge from the photosynthesis and respiration of cyanobacteria, which are the microorganisms that make up blue-green algae.

"Both photosynthesis and respiration, which take place in plant cells, involve electron transfer chains. By trapping the electrons released by blue-green algae during photosynthesis and respiration, we can harness the electrical energy they produce naturally,” said engineer from Concordia University in Montreal.
