A system includes a wellbore that extends from a surface into a subterranean formation. In addition, the system includes a power generation assembly including a fluid circuit that is in fluid communication with the wellbore wherein the power generation assembly is configured to generate electricity in response to a flow of a working fluid through the fluid circuit. Further, the system includes a bubble pump positioned within the wellbore that is configured to circulate the working fluid between the fluid circuit of the power generation assembly and the wellbore via a thermosiphon effect.

A plenum resident wind turbine sustainable energy generating system is disclosed. An example embodiment includes: a wind turbine assembly installed in a plenum of a heating, ventilating, and air conditioning (HVAC) unit, the wind turbine assembly including a plurality of blades and a transverse shaft; and a generator coupled to the shaft of the wind turbine assembly.

An energy collection system for capturing wind energy being exhausted from an air exhaust system. The energy collection system has a frame and a wind turbine. The wind turbine has a blade configured to rotate about a shaft. Air leaving the air exhaust system in a vertical direction causes the blade to rotate which is then converted by the wind turbine into electricity.

An apparatus and kit for capturing waste air flow wherein the apparatus comprises a shroud locatable over the waste airflow source, a first fan rotatably mounted within the should and a first electrical generator motor operably connected to and driven by rotation of the first fan, wherein the first fan is rotatable in a first direction by the waste air flow. The kit further comprises a second fan sized to correspond to and replace an existing axial fan.

An energy recapturing apparatus is disclosed. The energy recapturing apparatus is housed within a frame that is configured to fit within a preexisting fluid passageway. The frame is further attached to a sliding mechanism, which enables the frame to be easily removed from the preexisting fluid passageway. Further, the frame is configured to accept at least one turbine that contains a plurality of blades. The turbine is able to convert the energy of fluid movement into electricity.

An energy production device for a chargeable energy storage is arranged on a fluid conduit of an existing fluid circuit in a device through which a fluid flows. The fluid flow in the fluid conduit primarily serves a predetermined purpose different from that of the energy production device. The energy production device is arranged to produce energy from the kinetic energy of the fluid flow to charge the chargeable energy storage. A module insertable into the device may include the energy production device. The device may be a washer disinfector for processing medical instruments, systems and/or products that include at least one handpiece having a chargeable energy storage. The energy storage is configured as a rechargeable battery or as a power cell and is adapted to be processed together with the handpiece in the washer disinfector.

In one aspect, a system for generating electricity based on water flow is disclosed. The system comprises a first pipe fitting, a turbine, and a second pipe fitting. The first pipe fitting couples to a pipe that supplies a fluid to a building. The turbine is in fluid communication with the first pipe fitting and rotates in response to a kinetic energy of the fluid supplied by the pipe flowing through the turbine, generates electricity in response to rotation of the turbine, and reduces a pressure of the fluid from a first pressure to a second pressure. The second pipe fitting couples the turbine to an input pipe of the building. The turbine further comprises a conversion circuit that conditions the generated electricity for consumption by the building and conveys the generated electricity to the building via one or more conductors.
