Koleda claims that its Solus radiator converts 100% of electricity to heat, thanks to its graphene-based heating element. It has a thermoregulator, weighs under 10lb, is only 0.4″ thick and has a minimalist design. It can be powered via AC or DC.
Art Lebedev Studios outs one of its greatest ideas yet, a radiator that looks like the bones of the mighty (except for its arms) T. Rex. Alas it’s only a concept, but shut up and take our money already.
