This video started to go viral yesterday. It's good timing; given that PayPal are making waves today with their NFC app and TED is back in the UK.
What this video shows - and it's a video from 2009 - is a TV set, a Nokia phone, an iPhone and an Android being charged by remote power. This is power without cables. This is the future.
If you're wondering why this video sprang back to life, 2 years after it was filmed, it's because of rumours that Apple was experimenting with new charging methods for 2012.
WiTricity is a trademark term too; it's a company. Frankly, it's certainly a company I imagine we'll be talking about a lot more in the near future.
