Gamma-rays have thousands to millions or even billions of times the energy of ordinary sunlight.
The design aims to increase efficiency by reducing the amount of energy lost when sunlight is reflected off the solar cell or absorbed into the material before reaching the contact wires.
Their solution was to yield most of the canvas or panel to the gray, fog-and cloud-filled sky (curator Emilie Gordenker, director of the Mauritshuis, calls them "our Dutch mountains"), with blue openings torn into the gray here and there so that spots of sunlight could illuminate parts of the land or water below.
Any individual who had a genetic mutation that lightened his or her skin (and eyes) would absorb more sunlight, boosting health and the ability to survive and breed.
