Power cells get energy from plants

A team of researchers from the Optical Bio Microsystem lab at Concordia University in Montreal, Canada, have invented and developed micro-photosynthetic cell technology that can harness electrical power from the photosynthesis and respiration of blue-green algae.

This novel, scalable technology enables economical ways of generating clean energy, and may be the superlative, carbon-free power source for the future of mankind. The team headed by Dr. Muthukumaran Packirisamy, research Chair of the Optical Bio Microsystem lab at Concordia, has conceived and developed such a contraption. The report is featured in the September 2015 issue of the journal TECHNOLOGY.

Both photosynthesis and respiration, which take place in plants cells, involve electron transfer chains. The main concept herein involves trapping these electrons that are released by blue-green algae. The electron transfer chains of photosynthesis and respiration are constructive in harnessing the electrical energy from blue-green algae.

These micro photosynthetic power cells may entail significant military and wireless applications. They can also be good power sources for Bio Microelectromechanical systems MEMS devices. Of course, much work needs to be done in scaling the power cell and making this commercial. The team of researchers in Optical Bio Micro Systems is working to fabricate the high power density and high current density power cell in economical ways.
