Hi I was just thinking about using biological energy as a source of power. There is an animal called an electric eel that can pulse 600 volts of energy. So what if you could either:
Farm electric eels and condition the eels to regularly pulse there charge which can be collected stored.
Alternatively you could grow (geneticly engineer) just the skin and flesh of the eel and keep it in an oxygenated nutrient ritch solution. Then get it to pulse its energy but pulse it at a lower voltage but more frequently.
This could really work.
Have a great day
James
