Given the desert landscape of Arizona, it is perhaps no surprise that scientists at the state's university have been looking into the prospects of heat as an energy saving method
However, that does not undermine their discovery of a technique that could allow waste heat from devices to be converted back into power at a voltage 100 times that achieved by previous technologies.
Their energy saving invention is currently only a simulation, but the team say they have been assured that nothing in their virtual version would be impossible to reproduce in the real world.
Justin Bergfield, lead author on the study and a doctoral candidate in the college of optical sciences at the University of Arizona, says: "Thermoelectricity makes it possible to cleanly convert heat directly into electrical energy in a device with no moving parts."
As their rubber-like material is highly flexible, it could be used to coat parts of machinery that get hot - such as the exhaust of a car - and generate power directly from there.
Mr Bergfield's interests outside of the scientific realm include bonsai trees, playing violin, hiking, surfing and tea, his University of Arizona profile reveals.
