This looks to be very interesting.

It would be a whole lot more interesting if
a) it wasn't coming from the website of a lawyer who is the patent-law equivalent of the "ambulance chaser" or the vanity publishers advertising in the backs of pulp magazines
and if
b) there was a working prototype of some kind being demonstrated.
I was being cautiously optimistic, which is why i didn't go all out with 'extremely interesting' as a descriptor.
