A central air conditioning system is a welcomed appliance to own on hot summer days. They run efficiently and can cool off one, some or every room in your home. Most central air conditioning systems utilize a combination of gas and electricity to fuel and power the system. They also use f...
Natural gas prices are going up all the time.At what point does it make sense to replace my gas water heater (40 gallon) with an electric one?I live by myself and my July gas bill was $28. I take 1 quick shower a day, do 2-3 loads of laundry a week, and run 1 dishwasher l...
A control mechanism particularly for use with an absorption-type refrigerator of the kind which has provision for heating powered both by gas and by electricity, either of which may be used to the exclusion of the other. The control mechanism operates both an electrical switch for the electricity...

scanningelectron microscopeimage, and measured CV characteristics of a multi-field-plate AlGaN/GaN field-effect transistor (Chu et al., 2011b). From the CV characteristics measured between the gate and the drain, we can see multiple plateaus, corresponding to depletion of 2Delectron gasunder each...
Rolls-Royce has developed ground tests on a hybrid system with the M250 gas turbine, an engine usually employed on helicopters. Three operating modes: Series, Parallel and Turbo-Electric, will produce a power from 500 kW to 1 MW to be used on propulsion for eVTOLs, general aircraft and ...
the unprecedented low temperatures in China caused a huge surge in demand for heating that increased electricity demand35. The sharp increase in electricity demand, especially in southern provinces that do not have central heating in place, could not be met by existing generating capacity, resulting...
