PURPOSE:To efficiently collect the solar rays and to reduce the cost for facilities and power, by joining a plurality of rectangular convex lenses into a cylindrical lens, and arranging a heat receiving tube through the center of the cylindrical lens. CONSTITUTION:The plurality of convex lenses 1a each having prescribed curvertures on both surfaces are joined to form the cylinrical lens 1, while the cylindrical lens 1 is rotatably supported by bearings 3, and the heat receiving tube 4 extends through the center of the cylindrical lens 1. Accordingly, since the solar rays can efficiently be collected, and the adjusting of the angle of a reflective mirror and an apparatus for controlling the adjustment of the angle thereof are not required, the cost for facilities and power can be reduced to a large degree. |
