  • Patent number: 11859834
    Abstract: A micro-combined heat and power (mCHP) system includes a liquid cooled variable speed genset that is located to the exterior of a building and that is provides heat and power to the interior of the building. The genset may be configured to output an electrical supply of between approximately between 500W and 40 kW. A coolant loop may extend from the exterior genset to the interior of a building and is configured to reclaim heat from one or more sources of waste heat at the engine, generator, oil and/or exhaust. The reclaimed heat is then transferred, directly or indirectly, to the air flow path of a building heating system. In one embodiment, the reclaimed heat is transferred to a liquid circuit via a liquid-to-liquid heat exchanger and thence to the cold air intake of a forced air furnace via a liquid-to-air heat exchanger. A thermostat may control heat transfer from the mCHP to the heating system.

  • Patent number: 11840957
    Abstract: A load adaptive linear electrical generator system is provided for generating DC electrical power. The electrical generation system includes one or more power generation modules which will be selectively turned on or off and additively contribute power depending on the DC power demand. Each power generating module includes a pair of linear electrical generators connected to respective ones of a pair of internal combustion piston based power assemblies. The piston in the internal combustion assembly is connected to a magnet in the linear electrical generator. The piston/magnet assembly oscillates in a simple harmonic motion at a frequency dependent on a power load of the electrical generator. A stroke limiter constrains the piston/magnet assembly motion to preset limits.

  • Patent number: 11835025
    Abstract: A hydrodynamic power generation assembly and method of use therefor for generating electrical power from the combination of kinetic energy, hydrostatic energy, and turbulent energy of water. The power generation assembly comprises a water accelerator assembly comprising a support structure which is at least partially buoyant and a baffle panel member (or an array of baffle panel members) having an opening, inter-panel spacing, or flow passageway around the baffle panel(s). A hydropower converter is supported from, by, or on the support structure and is operatively coupled to a generator. The hydropower converter is positioned behind baffle assembly. Water flowing through or around the baffle assembly has an increased velocity relative the ambient current and therefore is capable of generating more power relative to the ambient water where power generation assembly is deployed. Particular types of hydropower converters suitable for use with the invention are turbines and water wheels.

  • Patent number: 11831271
    Abstract: A medium voltage inrush current (MVIC) regulator and interconnection control system for interposing between a distributed power generation facility and a utility grid. The facility has a designated generator step-up (GSU) transformer and is connected to the utility grid at a point of interconnect. The system includes a pre-insertion impedance injection transformer, a low voltage first switch connected between the pre-insertion transformer and secondary coils of the designated GSU transformer, a medium voltage second switch connected inline between the pre-insertion transformer and primary coils of the designated GSU transformer, and a controller. In response to restoration of the utility grid following a loss-of-grid event, the controller opens and closes the first and second switches according to an automated pre-energization switching sequence such that magnetic flux in the designated GSU transformer occurs at a reduced rate, thereby reducing inrush of current and undesirable power quality phenomena.
