I&#x27;ve worked on a few laser based wireless power systems and I don&#x27;t see it easily becoming safe enough for consumer use at power levels that are useful. For industrial&#x2F;military use, the only thing keeping them from being off the shelf is their high cost and maintenance requirements (oddball cooling system requirements and very clean optics).<p>If you want to charge your phone on the order of 1w&#x2F;hr, it&#x27;s possible, any more power than that, consumers can&#x27;t maintain equipment good enough for it to work. The main limiting factor for the power level is keeping things clean and scratch free enough. If you figure that out, it is worth more than wireless power system is (and I can I buy a few?).<p>One of the systems I worked on could deliver 1kW at 100m, and even something as small as a 0.5% reflection could set your clothes on fire if you were close to the reflection. 1KW is less power than what you can draw from most standard consumer wall outlets.
