Abstract: A black plastic formed from between about 0.01% and 0.3% carbon nanotube material by weight.

Abstract: A container that comprises first and second sidewalls and first and second end walls connected to a base. At least one of the base, respective sidewalls, or respective end wall is formed of a material that has a high thermal conductivity. At least each of the sidewalls or each of the end walls may be provided with venting to promote air flow. The first and second end walls and the first and second sidewalls are pivotally connected to the base.

Abstract: A thermally conductive polymer composition, comprising a polymer, conductive charges in an amount of about 35% by weight or less, and a compatibilizer, the composition having a transverse thermal conductivity of about 0.5 W/m/K or more and a deformation at break of about 850% or less The composition is fabricated by i) feeding a polymer and a compatibilizer in a feed zone of an extruder to obtain a melted resin; ii) introducing directly into the extruder downstream of the feed zone, conductive charges in an amount of about 35% by weight or less into the melted resin; and iii) providing a degassing zone before the output of the thermally conductive polymer composition produced.

Abstract: A geothermal heat pump has a pump. A tubing conveys a fluid from the pump and adapted to transfer energy between the fluid and the ambient environment as the fluid travels through the tubing. The tubing has a high thermal conductivity.
