thank you StephenW, i have seen your post on the chinese forum
this tech will probably work if they want to, i have seen a similar study about a filter make by US army against chemical/bacterial
war, this was 5-10 years ago.probably the
technology was not ok for US market because it destroys antivirals drug market and kept in a drawer, now it comes out at the other part of the world and since japan economy is not really ok they better use this technology
