Abstract: An energy recovery apparatus includes a fixed frame, a shaft, an impeller vane, and an energy transfer unit. A fluid stream exits the host device along a flow axis. The fixed frame defining a longitudinal axis mounts the host device. The shaft is rotatably mounted to the fixed frame parallel to the longitudinal axis. The impeller vane is connected to the shaft to cause rotation when the fluid stream of the host device strikes the impeller vane. The energy transfer unit is linked to the shaft to transfer energy from the energy recovery apparatus when the shaft rotates thereby recovering energy from the fluid stream. A geologic heat exchange system includes at least one conduit in thermal contact with the geologic environment. A coolant distribution system is in fluid communication with the conduit such that heat exchange with the geologic environment occurs.

Abstract: Systems and methods for generating resources using municipal solid waste are disclosed herein. According to one aspect, a method includes receiving wastes. The wastes can be separated into different portions for different downstream processes. Further, the wastes can be treated in an anaerobic digestion process for producing biogas. A gasification process can be applied to the wastes for producing synthesis gas. Further, an algal growth system can be applied for sequestering system-produced carbon dioxide (CO2).
