Mexican students experiment with micro-algae for solar power collection

Mexican college students have found that micro-algae can absorb sunlight and then generate electricity to be stored in cell for commercial use.

“For example, in comparison of solar cells, micro-algae has the ability to absorb about 90 percent of casual solar radiation, which solar cells can’t do right now.”

Because algae are everywhere, so the discovery is believed to be cheap and worth developing.

“The micro-algae can be drawn from the anywhere, even logged water. I think we can do it for a very small cell as our project, a single cell worth no more than 50 pesos.”

Power volume from micro-algae is easy to estimate at the current phase of the experiment which has been conducted at the Faculty of Engineering and Chemical Sciences at the Autonomous University of San Luis Potosi.

“From approximately 5 to 10 centimeters of micro-algae, we can obtain 270 milli-volts of power at their highest values.”

How it is collected in mass and commercialized is still a problem for the invention.

“This is an idea for future. In the future we can further improve the power system, with which we can even charge a cell.”

With the project recognized in Mexico, the inventors are now planning to promote it in December in Spain for international support.
