I've a section on Shawyer and a short paper by Andreas Rathke of ESA.

BBGB (Blow by Grinding Blow) or,, as close to enough information was herein supplied from picture and description for some of us to attempt a replication. There is also a patent, but I do not yet have that number. I thought I should just pass this along, all that I have.. The short description is : an unbalanced 2 gm force- derived from : a 2.45 GHz microwave- bouncing back and forth within a resonant chamber- that is wider on one it's ends.. The developer is a UK company SPR, director is Roger Shawyer. <http://www.emdrive.com/> Nasa is sceptical but there are reports of seven (7) independent reviews by : BAE Systems, EADS Astrium, Siemens, and the IEE. And... DTI ( a UK government agency?) has awarded the company 125,00 pounds for the prototype, part of a three year 250,000 pounds Program.
