Sprain? I haven't heard of him.
Patent no. US 6954019. An elegent implementation of a magnetic
gradient motor . . . sort of a circular SMOT.
Here's a brief video:

Here's a still:

You mean that he's closed the loop?
I have personally measured the COP at 2.35. Closing the loop has
proven difficult. This is the voltage we have gotten from a permanent
magnet motor attached to the rotor:

If I could spend more time on the project, I am almost certain we
could close the loop. But this waveform represents the gradient and
is difficult to turn into the 1 joule pulse we need to fire the
electromagnet. However, Paul is bored with this device having first
built it in 2003. Plus he now has a billionaire investor.
The device works from a gradient of 0.8 gauss per degree. We have a
new magnet under construction which will provide a gradient of 20
gauss per degree.
Watch this space. :-)

PS I have tons of data if you are really interested. Hope you got broadband!
