(ORDO NEWS) — Scientists from the University of Cambridge (Great Britain) talked about the creation of a computer powered by algae. The results of the study are published in the journal Energy & Environmental Science.
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 the energy of algae for more than six months.
Scientists said that in laboratory conditions, an algae-based battery could produce a small amount of energy. 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 of time we thought it would stop after a few weeks, but it continued to work,” said study author Dr. Paolo Bombelli.
According to the scientist, algae do not need food, because they create their own food in the process of photosynthesis. The findings obtained during the study can be used in the creation of autonomous gadgets for a smart home.
