  • Self-contained, PV-powered domestic toilet and wastewater treatment system
    Patent number: 10981811
    Abstract: A wastewater treatment system and method for remediating wastewater and human waste that is self-contained and that has no connection to a municipal wastewater system and no connection to an electrical grid. The domestic toilet and wastewater treatment system can be powered by a photovoltaic panel as a source of electricity. The system includes an electrochemical cell that allows a waste stream to be disinfected in a few hours to a condition where no viable bacterial colonies can be cultured. The system produces a liquid stream that is suitable for system flushing or for uses in which non-potable water is acceptable. The system can generate hydrogen as a product that can be used to generate power. The system can generate nitrate, urea, ammonia and phosphate for use as fertilizer. The disinfected residual organic solids are also completely disinfected for potential use as an organic soil amendment for agriculture.

  • Method and device for dendrite research and discovery in batteries
    Patent number: 9620808
    Abstract: An electrolytic coin cell that has been used to study the growth of lithium dendrites by optical observation is described. The cell makes possible observation of the growth of the dendrites in response to various applied conditions, such as applied electrical signals, chemical effects, and temporal effects in a real coin cell geometry.
