N2 - A lightweight, fully modular radiator design for heat rejection in space is proposed, which is estimated to weigh less than 2 kg per square meter of the effective radiator area. The feature which makes this thin membrane radiator practical is the internal electrostatic field system, which can stop radiator leaks from punctures, sudden accelerations or accidental tears. Preliminary design calculations are presented for a rotating conical radiator, using liquid lithium at an inlet temperature of 800 K. Remarkably low weights of less than 1 kg kW-1 may be attained, with safety factors of two or more for stopping leaks. This is almost an order of magnitude less than the values for current heat pipe designs.
