In an engineering feat straight out of a weird science-fiction story, researchers at Stevens Institute of Technology in New Jersey have taken an ordinary white button mushroom and used 3D printing technology to coat it with graphene microribbons and cyanobacteria to produce a device that generates electricity.
Scientists at the Oak Ridge National Laboratory in Tennessee were trying to find a series of chemical reactions that could turn carbon dioxide into a useful fuel. But the unexpected occurred: they found that the first step in their process actually got the job done all by itself. The reaction turns CO2 into ethanol, which is already used to power generators and vehicles.
