Seems to be that the day we won’t have to connect our electronic devices to the electricity to be charged at home is coming soon, thanks to the ubeam technique which provides a safe way to connect the wireless to power, so instead of charging via wires that have limited range and usually requires that the charger and device be in close proximity to each other.
Ubeam uses ultrasonic transducer to convert the power from the electric wall socket to inaudible sound power on the receiving side, which is the device to be charged, there is batteries with converter which can receive these waves and convert it back to electric power.
Ubeam wants to develop the wireless charging technique for home using and commercial using. Starbux was putting this technique in each of its branches so the clients can that has batteries compatible with this technique to charge their devices wirelessly.
The technique was developed by two graduates of University of Pennsylvania.
