Solar stepping stone
TLDR
In this article, a solar stepping stone (10) comprises a housing (70) having an upper surface (12), side walls (16, 18, 20, 22), a lower surface (14), the housing defining a chamber (32), and a solar energy collector (48) associated with the housing for collecting solar energy.Abstract:
A solar stepping stone (10) comprises a housing (70) having an upper surface (12), side walls (16, 18, 20, 22) and a lower surface (14), the housing (70) defining a chamber (32). A solar energy collector (48) is associated with the housing (70) for collecting solar energy. A solar power storage device (42) is provided in the chamber (32) for receiving and storing solar energy (42) received from the solar energy collectors (40). An illuminator (48) for illuminating at least a portion of the upper surface (12) of the solar stepping stone (10) is contained in the chamber (32) and is powered by solar energy stored by the solar power member (42).read more

Patent
Radiant energy conversion system
TL;DR: In this paper, the authors describe a system consisting of an enclosure that shields its contents from environmental effects while allowing radiant energy to transmit through its top window; a plurality of energy concentrating or collimating assemblies, each on its own pivot mechanism and each comprising a plethora of optics, a support structure and an energy conversion device that is mounted on a heat dissipating structure; a drive mechanism controlled by a microprocessor to rotate the said energy concentrating and collimating assembly on two orthogonal axes in unison so the assemblies are oriented towards desired direction at any given time.
Patent
Photovoltaic-embedded surface
TL;DR: In this paper, an integrated solar power system that provides electricity to external electrical devices has a trafficable surface formed from a plurality of roadway panels arranged with respect to each other, each roadway panel has a solar energy collector, a layer of translucent and protective material covering the solar energy collectors, the material being sufficiently translucent to allow passage of light there through for absorption of light by said collector and sufficiently protective to withstand the loads and the impact of pedestrian and vehicular traffic.
