hmm I can't open that links..
maybe he used the word 'gas ram' to explain the concept of a partially balanced spool valve ?
well anyway... it would be cool if someone could contact him and ask him some questions
have you noticed that he mentions ether there ? I wonder if it works with pneumatic guns.. if it does then it wouldn't be that difficult to design a device that will meter and release a small amount of it just behind the projectile for each shot
