Algae can power small electronics devices, researchers show

The energy industry is constantly evolving, sometimes throwing surprising results. As current energy resources dwindle, mankind has been pushed into top gear to find new and reliable sources of sustainable life as we know it today. One of the most promising developments is the renewal effort to utilize solar energy. But there are limitations and solar energy must be supplemented with other resources. Researchers at the University of Cambridge in the UK have used algae to find the answer. They energized the microprocessor for more than six months without using anything more than a common strain of cyanobacteria, known as cyanocystis.

The researchers said their system has the potential to be a reliable and regenerative way to power small devices. Non-toxic algae cynocystis naturally derives energy from the sun through photosynthesis. The small amount of electric current generated during the process interacts with the aluminum electrode and is used to power the microprocessor.

The researchers said in a Advertising The system uses inexpensive and highly recyclable materials, which means it can be easily repeated hundreds of thousands of times to power a large number of small devices. It is very useful in remote areas.

Cambridge Professor Christopher Howe, co-senior author of the study, said the growing Internet of Things needs increasing energy to come from systems that can generate energy, rather than store it. “Our photosynthesis device does not work like a battery because it constantly uses light as a source of energy,” he added.

But if there is no sunshine for a long time – in the polar regions or in harsh winters? The researchers said that the device that produces the current as a result of photosynthesis could continue to produce energy during the dark period, as the algae would process its food to some extent in the absence of light.

The study was conducted Published In the magazine Energy & Environmental Science.

This system holds promise because it is impossible to use lithium-ion batteries to power everyday electronic goods.
