1. A method for supplying heat to a fluid which comprises:

  • (a) providing a body of rigid, interconnected, multidirectional and continuous strands of vitreous carbon forming a rigid, porous, three dimensional skeletal structure, said body being so structured that it can withstand sustained heating in air to about nominally 350°

    C. without cracking or significant electrical resistance change measured at room temperature; and

    (b) supplying electrical or electromagnetic energy to the body such that a fluid flowing in the body is heated by heat transfer.
