If you think everything that come out from that part of your body are waste products, thats where you are wrong, at least sperm are most important of all.
Other than that reproduction fluid. A single drop of urine also contain 1.5v of battery power, same as a AA battery, according to Dr Lee Ki Bang, Institute of Bioengineering and Nanotechnology in Singapore. (Link)
No wonder! Sometime I experience shivering during my water work time, must be the electrical charges from my urine, 1.5v X how many drops was there? is a miracle I never got electrocuted.
More, if you have many members in your family, every time they go toilet, you can now provide them plastic bag and tell them to pack'em up later for sales or keep for future, that way you can save energy or even let SP (Singapore Power) cut you electricity away, without fear.
But than, my main concern are, like that the price of those real battery will slumber, bad for the economic, many will lost their job.
