Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

Abstract: An energy harvesting prototype (EHP) was designed to convert low-temperature heat loss from fluid into electricity. The method for energy conversion uses two antagonistically connected shape ...
