1. An evaporation apparatus comprising:

  • (a) a storage means for storing a liquid to be evaporated, the storage means including means for replenishing the liquid, wherein the liquid defines in the storage means a surface area, the surface area defining a liquid-gas interface;

    (b) an evaporator means associated with the storage means; and

    (c) a displacement means associated with the evaporator means;

    characterised in that the evaporator means includes at least one heating element disposed to contact the liquid-gas interface and evaporate the liquid by thermocapillary convection, wherein the storage means is operable to maintain the liquid in contact with the liquid-gas interface, and wherein the displacement means is operable to displace vapour created by operation of the evaporator means.
