1-27. (canceled)
A fecal waste processing system for electricity and potable water generation, comprising:
- a steam-powered electricity generation system comprising a boiler assembly, a steam engine, and a condenser interconnected and having a primary water circuit that carries primary water through the boiler assembly, steam engine assembly, and condenser, wherein operation of the steam engine assembly generates electricity;
- a fecal sludge system that receives at least a portion of the electricity generated from the steam engine assembly, the fecal sludge system comprising a sludge dryer assembly and a sludge delivery system configured to deliver a flow fecal sludge to the sludge dryer assembly, wherein the condenser is attached to the sludge dryer assembly and configured to deliver first heat to the flow of fecal sludge to liberate water as first steam from the fecal sludge and to dry solid fuel material in the fecal sludge;
- a water collection system connected to the sludge dryer assembly and configured to receive and condense the first steam for collection in a collection portion as clean, liquid potable water;
- and
- combustor system connected to the fecal sludge system and the boiler of the electricity generation system, the combustor system comprising a combustor configured to burn the dry solid from the fecal sludge system and provide heat to water circuit in the boiler assembly, wherein the boiler assembly provides steam to the steam engine.
