Abstract: An electric boiler includes a first electrode disposed within a chamber and comprising an upwardly oriented water nozzle surrounded by a convolute electrode member. A second electrode is disposed within the chamber vertically above the first electrode and has a bottom center opening for receiving water from the nozzle and a dome for redirecting the same radially outwardly. The second electrode also includes an annular water receptor surrounding said opening and having a plurality of drain openings spaced from the center opening and a plurality of pipe sections of different lengths disposed respectively in said openings for discharging water downwardly onto the convolute electrode member. Control means is connected to the nozzle for varying the water delivery rate therefrom in response to steam pressure in said chamber.

Abstract: The solar energy collecting system of the preferred embodiment of the present invention includes two sets of louvers, adapted for being mounted in a window opening. A first set of louvers is mounted vertically, each louver having a pivot point at its top and its bottom. This set of louvers is controlled for reflecting infra-red rays of the sun toward the inside of the building in which the system is installed. The second set of louvers is mounted horizontally and usually interiorly of the first set. The horizontal louvers also include pivot points at their ends and a control system is provided for reflecting and focusing the rays reaching their surfaces to an energy collector.
