The Enometer ~ 2014
The Enometer is a prototype device that would be used by hobbyists to detect real nature in a future of synthetic biology. The concept is based on speculation by Allan Widom that bacteria can produce Electro Magnetic Frequency and be monitored via audio through the use of an induction coil. The device is pseudo scientific and the paper considered quack science. The paper in question can be found here, as well as additional reference to the paper by Luc Montagnier here.
