Abstract
Hydrogen is produced by dissociation of water in a rotary tubular reactor (1) having a receiving end covered by a cap (2) transparent to solar radiation and provided with a small window (12) connecting a collecting chamber (3) to an opaque insulated heating chamber (5). The tubular reactor (1) constitutes a "black chamber" provided with two series of tubes (7, 8) for heating and dissociating the water. Tubes (7) have a porous section (7a) for separating hydrogen by molecular diffusion according to Knudsen's principle. The concentrated solar radiation entering through the small window (12) falls on one end of the tubes (7, 8) and is largely absorbed by multiple reflections on these tubes. A slow rotation of the reactor (1) enables the bending forces and stresses due to the weight to be compensated.
