Scientists from the University of Cambridge created a computer powered by algae, Energy & Environmental Science reported.
Specialists assembled a system based on ARM Cortex M0+ microprocessors and a bioaccumulator based on a strain of freshwater cyanobacteria Synechocystis. The resulting computer continuously worked on algae’s energy for more than six months.
Scientists said that an algae-based battery could produce a small amount of energy in laboratory conditions. The weak electric current resulting from photosynthesis was transferred to an aluminum electrode and used to power the microprocessor.
“We were impressed with how well the system worked over a long period – we thought it would stop after a few weeks, but it continued to work,” said study author Dr. Paolo Bombelli.
According to Bombelli, algae do not need food since they create their food with photosynthesis. Additionally, the discovery obtained during the study can also be used for creating autonomous gadgets for a smart home.
