Systems and methods are described that employ high-intensity lasers to set up a thin plasma sheet, also called a waveguide or 'hot shell', in the atmosphere as a function of beam intensity and geometry. A laser beam can be spread and directed with physical optics (e.g., lenses, mirrors, other optical elements, etc.) to generate a thin inverted cone-shaped hot shell waveguide in the atmosphere. The hot shell of the waveguide has a different index of refraction (n) from that of the surrounding air layers and as such serves to internally reflect portions of the entering solar rays entering an aperture in the hot shell, toward the tip of the cone and a solar energy storage component positioned there, thus providing a virtual solar energy concentration system. In another embodiment, the solar energy storage component shuts down or otherwise rejects incoming solar energy when fully charged, to mitigate damage to system components.
