Hi All,

Im looking for information and news relating to Power Over Wireless technology. A number of Universities are researching and developing this technology, Im just wondering whether anyone has any news relating to this technology?

Thanks.

Do you mean powering a mouse/cell phone from an inductive pad sort of wireless, or powering your TV 20m away from the nearest power source type of wirelesss?

Things like this exist for years, decades... Check Electromagnetic induction for example. This how those rechargeable toothbreush and shavers work.

Making those available for large devices though is a different story.

In any case, there are companies working on different concepts, like mentioned before, mousepads that can recharge a mouse. But those still use contact. I saw a solution during the CES 2007 that would allow devices to be recharged when placed on a special strip on a flat surface. But the device had a special dongle (that they expect to incorporate to the device's designs in the future) that would establish contact with the recharging surface.

All pretty much in initial stages of development I'd say...

The University of Auckland School of Engineering has been working in this field for a number of years. They have successfully used INDUCTIVE POWER TRANSFER to power small vehicles on assembly lines as well as to recharge the batteries of a tourist bus in Rotorua.

One of the professors at the School of Engineering, John Boys has been the driving force behind this technology. Do a search on Google for "Inductive Power Transfer" and you will find plenty of references.

How about transmitting AC over wireless? Nikola Tesla tried it but probably ran into problems when the power companies realised that it would be difficult to tariff.

Sounds like you work there, are you the lecturer Grant in the ECE department?
