Talking about wireless power. How to harvest the energy from the air from existing sources. This has been around for about one hundred years. The problem then was that the devices then used lots of energy on both ends of the send-receive chain. Today devices are far more efficient and it is now possible to reconsider.
Today we can harvest the ambient energy. There are three considerations: what is doable, what is safe and what makes sense. there are some devices that make sense. he believs that one day devices will be able to harvest energy as we walk down the street. these would be small devices. VERY COOL. the wireless revolution is not complete. within 30 years, wireless will REALLY be wireless.
