Publication number: 20220275970Abstract: A planar non-imaging optical element (10) for a solar concentrator is described. Groups of circular and concentrically arranged microstructures (35) are arranged to refract light incident normal to the plane (504) of the optical element (10) towards the centre point (502). The angle of the microstructures (35) with respect to the plane (504) of the optical element (10) within each group increases with increasing radial distance from the centre point (502) and are selected such that upon normally incident light (60) they to form a focal area common to all of the groups at a focal plane (506) of the optical element (10) and further selected such that the light refracted from the smallest radial distance from the centre point (502) within a given group and the light refracted from the largest radial distance from the centre point (502) within a given group cross at a plane (518) closer to the optical element (10) than is the focal plane (506).Type: ApplicationFiled: August 1, 2020Publication date: September 1, 2022Inventor: Henrik Pranov

Patent number: 11408308Abstract: Disclosed is a thermal storage solution which can operate without any internal tubing or mechanical pumping in the heat reservoir, and features a heat transfer technology based on evaporation and condensation of heat transfer fluids that will prevent hot and cold zones in the thermal storage reservoir. The main advantage is that the reservoir will have a much lower cost, have more degrees of freedom regarding the interplay between storage capacity, input and output power, and can operate without any mechanical or pressurized parts.Type: GrantFiled: March 1, 2018Date of Patent: August 9, 2022Assignee: Heliac APSInventor: Henrik Pranov
