A while back (Last year as I remember) there was mention of a patent
claiming to tap the zeropoint. It used spheres at different polarities I
think. If anyone knows the patent number please let me know as I am
attempting to compile a list off all such patents. So far searches on the
IBM engine have turned up nothing.
