Much of the technological progress in the mainstream is designed to remove the inconvenience of wires. From backups of entire hard drives to the cloud, Bluetooth connectivity, to next generation streaming services, everything seems to be moving towards a future without wires. Extending this same principle to transmitting power wirelessly would mean a future where you don't have to worry about having the wrong wire to charge your device.

Hornby, the UK's premier model train company, is working on adapting wireless power technology using the principles of magnetism to its model trains. Through the use of small pads with magnetic coils, power is transmitted wirelessly from the pad into a receiver built into the device (watch video)

You could have multiple devices sharing the same power source, without a rats nest of wires to get tangled up. Other products could effectively work without batteries (games controllers, leading having to juggle multiple different ports and cables, leading to a future of much more sleekly designed products.
