An interesting idea from scientists is to get energy from biological processes. Now they extracted a protein that may be used as a micro-reactor to produce energy within a biofuel cells.

According to the reserachers, these preliminary findings suggest that these protein have the potential to be used in developing small biofuel cells:

Using pure protein opens up the possibility of shrinking biofuel cells to power small electronic devices, Squier said. Whole-organism biofuel cells require engineers to design a space-adding membrane that prevents unwanted reactions between fuel, the charge-transporting agent and the electron-accepting metal, the latter being the electrode that carries the electricity to the device.
