Swedish researchers have devised a way to turn bioluminescent jellyfish into solar cells [2]. It works like this: the green fluorescent protein (GFP) that makes the Aequorea victoria glow is simply dripped onto a silicon dioxide substrate between two electrodes. The protein works itself into strands between the electrodes. When ultraviolet light [3] is shined on the circuit, voila, the GFP absorbs photons and emits electrons, generating a current.

As much as Inhabitat is skeptical about using animals as raw materials, this is an intriguing discovery because jellyfish [5] are increasingly overpopulating the oceans as the waters become too toxic and acidified for more delicate species to bear. Using them to create carbon-neutral energy could potentially help restore the oceans to balance.

The GFP-powered cells work like dye-sensitized solar cells [6], but don’t require expensive materials such as titanium dioxide [7].
