Diamond Machine "Mr. Potty"
Some People have serious problems paying for food...How about a fuel less generator to turn poop into carbon disk then a machine ( powered by fuel less high voltage electricity )  "small in scale" to compress and heat the carbon into diamond...then to sell the diamonds for industrial applications or as gems to then pay for the food in the first place... just a thought...The system may also be useful for interstellar space craft outer hull coatings to then also aid with impact resistance.... The system does require a "seed" diamond to start the process... the system will then  allow the "seed" diamond to then grow in weight....and increase in size.  The system may harvest it's water via fuel less dehumidification powered by the draft cycle generators.
