Future Electronics Could Be Powered by Sugar

Finally, scientists have come up with a way to combine my two favorite things: music and sugar. Japanese researchers report in the latest issue of Energy and Environmental Science that they have created a biofuel cell that uses enzymes to break down sugars. Four of the cells combined produce 100 milliwatts of power— enough to run an MP3 player with speakers or a remote-controlled car.

Each cell consists of an anode and cathode separated by a proton-conducting membrane. Sugar—or another renewable fuel— is oxidized at the nanode, where it generates electrons and protons. The electrons and protons then combine with oxygen at the cathode to form water.

The researchers amped up the cell’s energy output by using an electron transfer mediator to move electrons between the electrodes and enzymes.

The Japanese biofuel cell is the first to have an energy output high enough for practical applications, so hopefully it will unleash a flurry of interest in the field.  And who knows—in the future, you may power even larger electronics with biofuel cells.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
