Img.080 (#G1b) Effects of the operation of a heater constructed by the hobbyist from Belgium. This heater boils a glass of water shown on the photograph "c" on the right side of this illustration. The above photograph captures the appearance of bubbles of steam which the work of such a heater always rapidly induces in the entire volume of the boiled water.

Img.081 (#G1b) The appearance of another prototype of the heater used in photo "b", and water prepared for a test boiling.
