    Abstract: A system is provided that integrates an autonomous energy harvesting capacity in vehicles in an aesthetically neutral manner. A unique set of structural features combine to implement a hidden energy harvesting system on a surface of the vehicle to provide electrical power to the vehicle, and/or to electrically-powered devices in the vehicle. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below. The layers uniquely implement optical light scattering techniques to make the layers appear opaque when observed from a light incident side, while allowing at least 50%, and as much as 80+%, of the energy impinging on the energy or incident side to pass through the layer.

    Abstract: A particularly-formed multi-layer micron-sized particle is provided that is substantially transparent, yet that exhibits selectable coloration based on its physical properties. The disclosed physical properties of the particle are controllably selectable refractive indices to provide an opaque-appearing energy transmissive material when pluralities of the particles are suspended in a substantially transparent matrix material. Multiply-layered (up to 30+ constituent layers) particles result in an overall particle diameter of less than 5 microns. The material suspensions render the particles deliverable as aspirated or aerosol compositions onto substrates to form layers that selectively scatter specific wavelengths of electromagnetic energy while allowing remaining wavelengths of the incident energy to pass. The disclosed particles and material compositions uniquely implement optical light scattering techniques in energy (or light) transmissive layers that appear selectively opaque, while allowing 80+% of the energy impinging on the light incident side to pass through the layers.

    Abstract: An electrically-powered device, structure and/or component is provided that includes an attached autonomous electrical power source in a form of a unique, environmentally-friendly structure that is configured to transform thermal energy at any temperature above absolute zero to an electric potential without any external stimulus including physical movement or deformation energy. The autonomous electrical power source component provides a mechanism for generating renewable energy, or a renewable energy supplement, as primary or auxiliary power for the electrically-powered device, structure and/or component. The autonomous electrical power source component is formed of one or more elements, each of which includes a first conductor having a surface with a comparatively low work function, a second conductor having a surface with the comparatively high work function and a dielectric layer on a scale of 200 nm or less interposed between the conductors.
