[[Randall]] suggests increasing the security of your home power supply by air-gapping it, using the light from a powered lightbulb to power a solar panel which then supplies power to the home, such that there is no physical wired connection between your house and the public electricity network. This is a large and very inefficient version of an {{w|opto-isolator}}, but would protect equipment behind the solar panel from power surges such as lightning strikes (which in an improperly {{w|Ground (electricity)|grounded}} home could blow out the light bulb, but not so easily risk frying the equipment beyond the photovoltaic cell and its inverter). Due to its inefficiency, this approach would waste substantial amounts of energy. Optical power beaming is being investigated to recharge drones in flight.[https://www.youtube.com/watch?v=9MI2ph9jptM] | [[Randall]] suggests increasing the security of your home power supply by air-gapping it, using the light from a powered lightbulb to power a solar panel which then supplies power to the home, such that there is no physical wired connection between your house and the public electricity network.
