Edge on cooling from nanostructure beats physical limit

Sucking the heat out of modern electronics is a technical feat all by itself.

And we've tackled even stickier situations, like cooling objects in the vacuum of space.

In electronics, heat can be conducted away to large surfaces, where convection can take care of the rest.

Heating and cooling can take place over long distances—light from the Sun warms the Earth through radiative heat transfer.

A less nice feature of radiative transfer is its efficiency.

In most cases, radiative heat transfer is negligible, but as soon as the temperature goes up substantially, it dominates conduction and convection.
