Swiss designer Fabienne Felder has worked with University of Cambridge scientists Paolo Bombelli and Ross Dennis to develop a way of using plants as “biological solar panels”. The team has prototyped the world’s first moss-powered radio to illustrate the potential of its Photo Microbial Fuel Cells (Photo-MFCs). Moss was chosen because its photosynthetic process makes the plants particularly efficient at generating electricity. The radio is the first time Photo-MFCs have been used to run an object demanding more power than an LCD screen. The team has high hopes for the potential of this emergent technology. “We may assume that in five to ten years the technology is applicable in a commercially viable form,” they said. Currently the technology used in the radio can only capture about 0.1% of the electrons the mosses produce. (source).
