Title: Generation of hydrogen by solar energy - using concave parabolic mirrors and wave guides to concentrate and conduct energy
Inventor: ROBIEUX JEAN
IPC: F24S23/00
Filed: 1975-05-09
Abstract: An appts. for generating hydrogen by solar energy incorporates a number of concave parabolic mirrors distributed over a surface. Each mirror can be moved so that its surface is directed towards the sun and a flexible wave guide conducts the light from the focus of each mirror on to one end of a rigid wave guide. The other ends of the rigid wave guides are connected by flexible wave guides to a vessel through which steam is passed. The conc. solar energy raises the temp. of the stem enough to dissociate it into H2 and O2. The H2 and O2 are sepd. e.g. by a porous partition and the H2 is stored, and can be used to feed a gas turbine driving a generator of electricity. Each flexible wave guide consists of a bundle of optical fibres. The rigid wave guide has a sleeve and a core made from two glasses of different refractive indices, or it consists of a plastic sleeve contg. a liq. e.g. bromobenzene. The device provides a means of storing the energy derived from the sun, whereas existing appts. using e.g. the photovoltaic effect of pn semiconductor junctions, have very low efficiencies in winter and can be used only during daylight.
