I had an idea of making electric current from bacteria. There're some bacteria that can make photosynthesis, and some others are capable of transmitting electrons trough each other. Is it possible that trough genetic engineering, we could insert the genome that allows a bacteria to make photosynthesis, with other capable of transmitting electricity, and therefor making a bacterial culture, big enough to make a free energy source?
