Abstract (en)

[origin: GB2441149A] A thermodynamic energy conversion device 14 based on the effect of differential evaporation generated by convex bending of a liquid surface and by temperature gradient is constructed for the use either as a heat or hydraulic pump. The device 14 comprises two heat conductive containers 1 and 2; a working liquid 5 disposed in said containers so that it has open surfaces 6 and 6'; a vapour 7 of the working liquid; a surface bending device 8 creating at least one convex meniscus 9 on the open surface 6, said convex meniscus having higher mean curvature than that of the open surface <B>6'</B>; means <B>10</B> for connecting containers 1 and 2 to an external hydraulic circuit 11. An efficient external combustion engine using device 14 is disclosed.
