Along with butterflies and moths, whose eyes have inspired scientists to build more efficient solar cells, a particular type of fly (the blowfly) has been discovered to have the right properties that would make us harvest the sun more efficiently.
Yale University researchers created a blueprint for artificial eel-like power cells. Their design is even more efficient and powerful than the natural one they’re mimicking, and could one day be used in powering small medical implants.
MIT researchers found out a way to create energy by mimicking the photosynthesis process that green plants acquire their energy from. Prof. Daniel G. Nocera and former MIT graduate student Alan F. Heyduk invented a hydrogen-producing compound. They also use a catalyst and small amounts of light.
