Disclosed is a system comprising an envelope of a structure, heat pipes and fluid conduits, the envelope of the structure including at least two shells spaced apart from one another which enclose an intermediate space being sealed against an interior and exterior of the structure. First and second pipes, embedded in the exterior-facing and interior-facing shell of the structure, respectively, penetrate the envelope of the structure and together form the heat pipe for the circulation of a fluid to increase, hold or decrease heat transition through the envelope of the structure or affect heat transport into or out of the envelope of the structure.

The present invention relates to a solar power generating apparatus comprising: a body (100) having a three-dimensional shape so as to enable air flowing from the outside to be lifted, and having an acceleration flow path (142) formed on the top thereof so as to induce a bottleneck phenomenon of the air to be lifted; and a power generating fan (200) installed in the acceleration flow path (142). Accordingly, the air flowing into the body (100) is heated by sunlight and is lifted so as to operate the power generating fan (200) and enable power generation, such that eco-friendly energy can be produced.

Falling particle solar receivers, systems, and methods are disclosed that include one non-linear falling particle curtain or two or more falling particle curtains within a solar receiver that receives incident solar radiation. The particles heated in the solar receiver may be used to heat a secondary fluid. In an embodiment, the particles may be recirculated to improve energy capture and thermal efficiency. In other embodiments, an air curtain may be used across the aperture of the receiver, and flow-control devices may be used to evenly spread particles across the width of the receiver inlet. Finally, feed particles may be preheated using heat from the solar receiver.
