The wind turbine power of the future can be stored in sustainable batteries made from fungi. In the future, when solar cells and wind turbines produce more electricity than we can use, the energy can be stored in environmentally friendly and inexpensive batteries made from fungi. At least that¡¯s the case if you ask PhD student Sebastian Birkedal Kristensen, his fellow researchers lector Jens Laurids S?rensen and Jens Muff and the rest of the researchteam, who invented the fungal battery and are now working to develop it on a larger scale.
