Graphene heats up

A new type of heating system to replace domestic and other radiators uses a thin graphene sandwich to generate far-infrared light rather than simply radiating heat from hot water inside or circulating warm air. The developers of the system suggest that up to 70% energy savings might be possible with their system. Moreover the fact that the technology is flexible means it can be wrapped around a water cylinder and so act as both insulating and heating element. The high surface area to volume ratio of graphene makes it a very efficient IR emitter, it can be incorporated into polymers or inks for screen printing allowing it to be used in a wide range of devices and form factors. Moreover, it can take an AC or a DC current so can utilize sustainable electricity from wind turbines or photovoltaic solar panels and so avoid the inherent efficiency reducing of needing an electrical inverter.
