Methods that can produce even small amounts of power from urine could be useful to help power office buildings or farms where there are a lot of people or animals all peeing in the same place, and smaller fuel cells could even also be used to power portable electronics, with no need to carry any fuel or batteries, just a…

Type8. [Attribute/State]à Interactionà [Useful State]: 2.4) Change of
structure or object makes interaction between its "attribute/state" and the

Any guesses? Head past the break for the big reveal. Trust me - you'll be surprised.
Got it yet?
