I'd be giving the patents away...

Thanks e14 for pulling those articles.

I was able to read it when it was first posted and I had a good chuckle. While we have yet to understand all forms of energy exchange and the efficiency of most applications can be much improved on - there is no such thing as "free energy".

I believe that sun and wind are "free energy" sources and lucky we are,..... we have not yet started a war about it.

Interestingly, the only one mentioning RF is Richard Cullin.

There is some hint around it because of the frequencies they see doing the test, but there was no mention of capturing radiated (ie in free space).

You already get radiated while using Wireless, so don't worry.

He did say (directly because element14 seemed to pass all my details)

The device in te Exodus and PowerStic packaging sits

right across the USB power and gnd. It does nothing to laptop settings since it

is not connected to the data lines. It simply harvests noise from the SERDES

data transfers and such or other I/O activity on the I/O supply, processes the noise, and feeds it

back into the system for power reduction.

Looking at the documents, the device is basically improving the performance of the voltage regulator. (ie efficency)

The comment on their page

Maximum battery life extension is seen when the user engages in a high amount of Computer and Portable Device Input/Output activity such as USB data transfers, CDROM activity, Keyboard/Mouse activity of any kind, or other Human/Computer interaction (see the non-exclusive list below).  Minimum extension of battery life is seen with the Computer or Portable Device simply powered on, with no I/O or Human Interface Activity

.and the image

would suggest that the claimed savings may not be seen in ALL devices ... a challenge test could prove it.

I do know that switch mode supplies are electrically noisy, but whether a few components can improve this and therefore save your battery is the $64k question.
