A double point focusing solar energy collection apparatus of the present invention includes a heat collector, a secondary concentrator, and a bracket. The heat collector includes a primary concentrator and a heat collection tube, in which the primary concentrator has a focus point. The secondary concentrator has a focus point. The bracket supports the primary concentrator, the heat collection tube, and the secondary concentrator. The heat collection tube is located between the primary concentrator and the secondary concentrator and located on the focus points of the secondary concentrator and the primary concentrator. By adding the secondary concentrator, which is a rotating paraboloid reflector or circular Fresnel reflector, it can achieve low light loss and high heat collection efficiency, and erosion of the heat collection tube by sand, rain, and snow can be effectively prevented, thereby extending the lifetime of the heat collection tube effectively.

A solar heat exchanger for heating water which includes an array of tubes, an injection molded manifold there being connections between each tube in the array and the manifold which are over molded to seal the tubes to the manifold.

The invention relates to a parabolic trough collector comprising a parabolic, trough-shaped main reflector, preferably as a steel girder construction running holding device with a plurality of support arms for holding of the main reflector, an absorber tube, which extends along the focal line of the Main reflector extends and in which a heat transfer medium is heated, and a foundation, wherein the holding device on the foundation by a vertical axis is rotatably mounted.

Disclosed is a device with a heat exchanger having a first flow through which a first gaseous heat transfer medium passes and a second flow through which a second gaseous heat transfer medium passes. Upstream of the first flow, there is a combustion chamber, which optionally extends into the first flow. Two feed lines are attached to the first flow, of which the first feed line is connected to a thermal solar installation and the second feed line is connected to a source for a combustible gas-air mixture or for a non-combustible gas, in particular an oxygen-containing gas, such as air.

The invention provides an apparatus which can heat water using a Fresnel lens or magnifying glass to focus and concentrate sunlight on water-filled radiator-like tubes which move water, by the water pressure from a water spigot/bib (without pumping), to:

1. move the heated water through tubes to heat any space inside any building, and

2. provide steam to power a steam-powered electricity generator to provide electricity, and charge a battery, during daylight hours, and then use the charged battery to supply electricity during the night hours, and

3. move water, cooled by the subsurface ground, by water pressure from a water spigot/bib without pumping, into proximity with any air space inside any building to cool the air space, and

4. array a series of magnifying glasses or Fresnel lenses in order to catch the rays of the sun from sunrise to sunset and focus those rays on the car radiator-like tubes full of water in order to heat the water without using fossil fuels, and

5. support the, array of magnifying glasses or Fresnel lenses and car-radiator-like water tubes with arch structures to hear the weight and protect the structure from earthquake damage.
