Solar heat absorbing tubing
First Claim
1. A heat absorbing tube providing enhanced solar radiation collection efficiency, which comprises in combination, a tubular member formed of plastic material containing a sufficient quantity of small electrical conductive black body absorber particles distributed throughout the thickness thereof to render said tubular member electrically conductive, and said black body particles being composed of conductive carbonaceous pyropolymer formed on a refractory oxide base material from a pyrolyzable organic material contacting said base material at a high temperature in the range of 400°
- to 750°

Abstract
An improved form of solar heat absorbing tubing comprises a plastic material which contains small subdivided black body absorber particles being fully distributed throughout the thickness of the tubing. A preferred form of tubing will utilize electrical conductive carbon, or carbonized particles, in an amount to provide conductivity to the resulting tubing such that there may be electroplating or electrostatic spray coating for the tubing to still further enhance its absorptive and reradiation properties.
