How Engineers Are Turning Wind Into Protein to Alleviate World Hunger

Researchers are getting creative with the extra energy from renewables' active periods by turning it into useful applications for humanity.

In this great clip, SciShow explains how researchers are working hard to develop new technologies that would allow the extra energy produced by renewables to be turned into protein. The Lappeenranta University of Technology (LUT) and VTT Technical Research Centre of Finland produced one such great experiment last year.

"In practice, all the raw materials are available from the air. In the future, the technology can be transported to, for instance, deserts and other areas facing famine. One possible alternative is a home reactor, a type of domestic appliance that the consumer can use to produce the needed protein," explained at the time Juha-Pekka Pitkänen, Principal Scientist at VTT.

"In the long term, protein created with electricity is meant to be used in cooking and products as it is. The mixture is very nutritious, with more than 50 percent protein and 25 percent carbohydrates. The rest is fats and nucleic acids. The consistency of the final product can be modified by changing the organisms used in the production," Pitkänen further added.

And according to estimates by these crafty researchers, this novel and ingenious process of creating food from electricity can be nearly 10 times as energy-efficient as common photosynthesis used currently for the cultivation of soy and other products.
