‘Moss-FM’ is the world’s first plant-powered radio.
It was developed by the designer Fabienne Felder, with support from scientists Paolo Bombelli and Ross Dennis. The radio runs entirely on energy produced by moss.
During photosynthesis, plants create surplus protons and electrons. Ten pots of moss produce about 25 microampere at 4.5 volts, enough to charge a battery that allows Moss FM to run. Using electricity from nature is one thing, but understanding why moss is producing it, is something else.
