Researchers at the Massachusetts Institute of Technology (MIT) have discovered that bacterial viruses can be used to build cheap, powerful and biodegradable batteries. Scientists at MIT's Department of Material Sciences used the 'bacteriophage' virus - which is common and harmless to humans - to build the positive and negative sides of the battery.
Batteries work by turning chemical energy into electrochemical energy when an electrolyte flows between a positively charged cathode and a negatively charged anode. Using genetically engineered organic viruses for the cathode and anode, rather than toxic materials, is the breakthrough.
Talk about thinking outside of the box...
