  • Patent number: 8643206
    Abstract: A water based renewable energy system is shown which uses tidal flow and an associated water wheel/weir assembly to provide pumping power for the system. A water wheel powered pump and associated piping are used to raise water from a lower lake reservoir to a higher storage lake reservoir. The water which is pumped to the higher storage lake can be released to a generator located at a lower elevation and then returned to the lower storage lake. The cycle can then be repeated by again pumping water from the lower lake to the upper lake. The pumped storage provides flow and head to generate electric power through the turbine generator.

  • Publication number: 20130071186
    Abstract: A system for stabilizing moisture content of soil adjacent a building foundation uses a French drain which is dug around a perimeter of the building and grey water produced in the building as a source of irrigating fluid. Grey water sources from within the building are directed to the French drain through conduits which are separate from the normal sewage lines leading to the sanitary sewer system. An overflow conduit diverts any excess overflow from the French drain to the sanitary sewer line.
