The PC has only been powered by blue-green algae for six months

In biology class, everyone probably saw something from Photosynthesis in plants Belongs to and important contribution to our environment. Now researchers at the University of Cambridge have succeeded in this A personal computer works for six months using photosynthesis.

This is how an eco-friendly computer using photosynthesis works

First, the interaction of light occurs, in which electromagnetic energy is absorbed in the form of light of a suitable wavelength. Then, the conversion into chemical energy is carried out through the transfer of electrons, which have been converted into an active state by a redox reaction. The final step is the light-independent reaction, in which chemical energy is used to form high-energy organic compounds, which are also used to produce energy. In other words, sunlight and carbon dioxide produce oxygen through the process of photosynthesis.

Christopher Howe and his team made a clear aluminum and plastic bowl the size of an AA battery. Inside, the team placed a colony of blue-green algae scientifically called Synechocystis sp. PCC 6803. Exposure to sunlight stimulates photosynthesis which supplies electricity to the anode and cathode. The device was installed on Paolo Bombelli’s window ledge from February to August 2021 and during this period it continued to provide electricity to power a computer with an ARM chipset. The computer has always been on for 45 minutes and simulates many computational tasks that require 0.3 microwatts of electricity. Construction continues to supply electricity continuously. It is still not clear how electricity generation via photosynthesis can be used in mass-produced devices. In the experimental setup, electricity generation through photosynthesis has already succeeded, and now there are further steps to be taken.

• As the University of Cambridge determined, blue-green algae power a PC. A personal computer can be powered by photosynthesis for a period of six months.
• Christopher Howe and his team made a clear aluminum and plastic bowl the size of an AA battery. A colony of blue-green algae was installed inside, which was stimulated to photosynthesis by the occurrence of light.
• ARM chips that consume 0.3 microwatts work as a computer.
