Dwindling resources have constantly challenged us to find new ways to incorporate unusual materials into producing everyday needs. We’ve masterminded lamps powered solely by bleach and cosmetics made from animal waste. Now, our Finnish friends have found a way to produce food using renewable energy sources like solar power.
Scientists just produced a single-cell protein from electricity and carbon dioxide, and it can be further developed for use as food or animal feed. The final product is a nutritious mix of more than 50 percent protein and 25 percent carbohydrates with the rest consisting of fats and nucleic acids.
While we’re not sure how tasty the oatmeal-like product is, it’s definitely packing a healthy punch. It’s not yet commercially available, but researchers hope to configure machines to produce meals quicker and more efficiently.
“In practice, all the raw materials are available from the air. In the future, the technology can be transported to… 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,”
The Lappeenranta University of Technology, where the protein is being produced, is working on developing the machine into a mass product. The device will also decrease greenhouse gas emissions and provide cheap production alternatives.
