I understand they have a small but high performance XTclaveTM. They have developped the process considerably since the hydroclave has been put in jv and then sold. Additional patents have been developped and lodged. Tests with the US military have happened. This has led to the higher performance they have announced a year ago and several tests undertaken by third parties. They have consistently said that a newly designed commercial size machine was being built on that basis and that they changed the strategy from pure licensing to actual manfacture, hence why they are building a new factory to locate the new XTclave and start production.
I think the logic is there and has been expressed clearly in all the recent communication. They have looked at all aspects to launch the product: unique capability, unique process and machine, production facilities and market. Robust strategy underpinned by good cash. Hard to fault.
