Bio electricity II

Just a side note to my previous post. You may be wondering why humans are used in the farms to generate electricity. Why not animals? The same can be achieved - clone lots of animals, cage them up, force them to walk on treadmill and since their intelligence is already low, there is no worry of a concerted attempt to rebel.

Of course, animals can be used. I just thought of using humans as we are bi-pedal, i.e. walks on two legs and thus more space-saving than a quad-pedal animal. In the light of ethical issues and other controvesy, perhaps animals might be a better choice. Ostriches, maybe?
