Abstract: A small processor produces potable water from contaminated water. Its components mount in a hermetically sealed housing, which include a boiler-condenser assembly and a compressor unit. Contaminated water is injected onto one or more aluminum shells' inside surface of the boiler-condenser assembly. Shell rotation enhances boiling heat transfer by causing the water to form thin films on the shells' inside surface. Shell rotation also enhances condensing heat transfer by assisting in removing the purified condensate from the shells' outer surface. The change of phase heat of condensation energy from vapor to liquid transfers through the shells to the boilers to cause boiling. Vapor boiled inside the boiler chambers flows toward the compressor, which raises the vapor's pressure and temperature to drive the process. Shell rotation causes centrifugal force that holds and directs concentrated un-boiled remaining water on the shells' inside walls towards the output pumps.

Abstract: Microbial fuel cells generate an electrical signal when microbes enter the cells through a semipermeable membrane. The single chamber microbial fuel cell comprises an anode adapted to be positioned near a potentially contaminated source to receive microbes on the source, a cathode spaced from the anode and carbohydrate positioned between the anode and cathode. The anode is flexible to adapt to a source that might have microbes. When microbes enter the fuel cell, the fuel cell generates an electrical signal. By reading and analyzing the signal from one or more of the fuel cell biosensors can indicate infection in people or animals, indicate pathogens growing in food or show mold growth. Insofar as different microbes have specific metabolisms, the signal may be used to determine which microbe is present.
