Massachusetts has set aggressive targets for heat pump installations for over 100,000 homes by 2025 and over 500,000 homes by 2030. But the high price of electricity in Massachusetts — the fourth highest in the nation — relative to natural gas or oil makes achieving these targets very challenging unless there is a major change in electricity policy.

A mode controller shifts, along with increase in an electric power in first and second of chopper circuits and, operation modes of the first and the second of the chopper circuits from a first mode to a third mode via a second mode. An operation controller causes, in the first mode, the first of chopper circuit to perform an chopping operation, and the second of chopper circuit to suspend the chopping operation, in the second mode, causes the first and the second of chopper circuits to alternatively perform the chopping operations, and in the third mode causes both of the first and the second of chopper circuits to perform the chopping operations.

A tree stand includes a housing dimensioned for holding electronic components used in providing electricity in support of decorative lighting for the tree. The tree stand removes heat from the housing without the use moving parts. Floor vents enable cool air to enter the housing; upper vents enable that air, warmed by the electrical components, to escape to the housing and into a heat riser housing as part of a growing, circular heat thermal. The heat follows a spiral ramp in the heat riser housing exiting vents at the top where additional heat is conducted into the tree itself, radiated into the air. Tree legs can be increased in number or replaced with longer legged trees without tools by insertion of the side wall into a slot formed in the legs and then slid around the circular slide wall from the notch where each leg is inserted.

An air conditioning system of a motor vehicle with a refrigerant circuit for operation in a refrigerator mode and a heat pump mode. The refrigerant circuit includes a primary circuit with a compressor, a heat exchanger for heat transfer between the refrigerant and the surroundings, an expansion element and a heat exchanger for heat transfer from the intake air being conditioned for the passenger compartment to the refrigerant, and a first flow path. The flow path extends from a branching point between the compressor and the heat exchanger to an opening and includes a heat exchanger for heat transfer from the refrigerant to the intake air being conditioned for the passenger compartment. The heat exchanger is situated in a flow direction of intake air of the passenger compartment after the heat exchanger.

Utilities are a natural partner for the geothermal heat pump (GHP) industry. Why? Because utilities have a broad consumer base and infrastructure, and need to both build load (sales) and levelize that demand to make the most efficient use of their electrical generation capacity throughout the year.  GHPs are a technology that fills that niche.
