Urine may be new source of cheap energy
Urine is being studied for its potential to create low-cost energy.
Researchers want to test whether it can be used in fuel cells as an alternative to flammable hydrogen or toxic methanol.
The work at Heriot-Watt University, Edinburgh, concentrates on urea, or carbamide, where scientists believe a Carbamide Power System could be non-toxic, low-cost and easily transportable system for use in submarines or by the military.
