An apparatus for converting solar heat into electrical power by building a large structure with a transparent roof at the edge of any steep high mountain having a large diameter pipe connected to the roof at the top end of the structure and laid on the surface of the mountain to the top of the mountain. A fan-operated turbine-generator installed at the bottom base of the large diameter pipe generates electricity. The invention includes constructing shallow pools or reservoirs inside the structure, storing the moisture generated via humid air and condensation at the top of the mountain in a pool or water tank, installing a return pipe to the original reservoirs or pools, and installing a hydro-electric turbine-generator at the bottom of the mountain on this return pipe to generate additional electricity.
