Apparatus, methods and systems of wireless power distribution are disclosed. Embodiments involve the redirection of collimated energy to a converter, which stores or converts the energy into a more suitable form of energy for at least one specific point-of-use that is coupled to the converter.

An optical element is provided which comprises a plurality of fluorophores disposed in a medium. The fluorophores have a quantum yield greater than 50% and an absorption spectrum with a maximum intensity at wavelengths less than 400 nm, and emit a spectrum of light having a maximum intensity at wavelengths within the range of 400 nm to 1200 nm. The optical element is at least partially transparent over the visible region of the spectrum. The optical element is especially useful as a window or other optical component of a greenhouse structure.

A sunlight reflecting assembly includes a box that has an entry and an exit. The exit is oriented at a substantially diagonal angle with the entry and the box is positionable outdoors such that sunlight passes through the entry. A first mirror is positioned within the box and the first mirror is comprised of a light reflecting material to reflect the sunlight that passes into the box. A second mirror is positioned within the box and the second mirror is comprised of a light reflecting material to reflect the sunlight that passes into the box. The second mirror is positioned on an opposite side of the box with respect to the first mirror. In this way the first mirror and the second mirror direct the sunlight that passes into the entry outwardly through the exit thereby facilitating the sunlight which passes through the exit to be directed toward a solar panel.

A transparent luminescent solar concentrator (TLSC) is provided. The TLSC includes a luminophore and a waveguide that guides light emitted from the luminophore. The TLSC has a light utilization efficiency (LUE) of greater than or equal to about 1.

A poly-layered, poly-dimensional solar photovoltaic stack structure may be provided in a tower form. A plurality of solar panels may be stacked on top of one another to create a solar stack tower. Using the solar stack tower, reflection, refraction, diffusion, and transportation of light may transmit photons from a higher area of photon saturation to a lower area of photon saturation. The solar stack tower may provide an enclosed structure, protecting and insulating the solar panels from heat, moisture, dust, and other elements that usually damage solar panels over time.

A transportation network for providing propellant in space can include optical mining vehicles that concentrate solar energy to spall captured asteroids, capture released volatiles, and store them in reservoirs as propellants. The network can also have orbital transfer vehicles that use solar thermal rocket modules that focus solar energy on heat exchangers to force propellant through nozzles, as well as separable aeromaneuvering tanker modules with reusable heatshields and storage tanks. The network can have propellant depots positioned between Earth and a transport destination. The depots can mechanically couple to accept propellant delivery and to supply it to visiting space vehicles.

An educational monument, comprising a designated geographical area accessible to a general public, a first structure having a first face positioned to receive a solar light beam, an aperture formed through the first structure for projecting the light beam at predetermined times and, a second structure positioned to receive the light beam at a first predetermined time. A third structure positioned to receive the light beam at a second predetermined time. Wherein a transition of the light beam reflects a change in the seasons and an alignment of Earth illustrating a physical representation of the transition at a plurality of successive predetermined times, each respective predetermined time being the same hour on a different day. Wherein a plurality of ellipses are scaled from the receiving wall, accurately representing the scaled orbit of the planets.

The present invention relates to a method for collecting sunlight through an image method by tracking the sun using a dish-shaped light collector or a paraboloidal light collector and, and to a method and an apparatus for transmitting high-density light as the collected sunlight to a remote place, to which the light is applied, and for generating super-high-density light by combining, in a multi-stage manner, the high-density light obtained through a plurality of light collectors. A first concaveparaboloidal reflector of a paraboloidal light collection unit can collect light, transmit the collected light to the remote place, and provide an efficient and quantitative use environment to an applied device by using a paraboloidal reflector set including: a first concave-paraboloidal mirror in which a slope of a paraboloide is provided to make a narrow width so that downward reflection is greater than or equal to 90% by an angle between an incident angle at an inner point of a paraboloidal mirror and a normal surface, the angle being larger than a critical angle, and which has an opening formed at the lower side of a central axis thereof; and a second convex-paraboloidal reflector, which has a small diameter, shares a focus of the first concave-paraboloidal mirror, and has a miniaturized shape of the first concave-paraboloidal mirror at a focal portion without an opening at a central axis thereof.

A sun-tracking light distributor system for use in an open-ended photo-bioreactor having an aqueous liquid for a photosynthetic culture, comprising: at least one light distributor each including a concentrator supporting section with a light entry surface adapted to receive sunlight rays, an elongated rod section with a light distribution surface adapted to redirect the received sunlight rays within the aqueous liquid, a light concentrating element provided at the light entry surface which concentrates within the elongated rod at least a portion of the sunlight rays received at the light entry surface; a displacement system operatively connected to the light distributors and adapted to change an orientation of the light entry surface of the light distributors to track a solar position.

A solar collector 1 for the temporary storage of heat from solar radiation comprising a radiation conductor 8, 9 for conducting the solar radiation, and lens means 7 for concentrating solar radiation onto a first extremity of the radiation conductor. A thermally-insulated core 2 is provided on an opposite second extremity of the radiation conductor 8, 9 in order to be heated by the solar radiation released from the radiation conductor and temporarily storing the heat. For this purpose, the core is provided with an insulated casing 4, virtually completely enveloping the core, which insulated casing 4 comprises a layer of porous ceramic material.
