From an Interesting Engineering online review:
Wi-Charge says it has a solution to the problem. Its technology allows users to power small devices, such as smartphones, smart fire alarms, and smart locks, from several feet away without any wires.
The technology works by sending out a thin beam of infrared light. A receiver on the enabled device then converts the beam into electricity.
Electronic waste is expected to exceed 50 million tonnes by 2020. That number simply isn’t sustainable.
One company is aiming to get rid of one of the main culprits in e-waste: the electronic cable. Wi-Charge has created a method for powering devices wirelessly using safe and efficient infrared technology.
Aside from having the potential to end a great deal of waste, the company is also aiming to meet a growing demand for power that will only increase with the advent of 5G.
