There have been some pretty convincing arguments against this technology being much use to us. I must admit I have my doubts that it would be worth the effort of trying it out. I think, though, that Richard's enthusiasm will give it a good try, and you never know, maybe he can find a way to make it work effectively enough to be of use. I think he should be supported in the effort no matter how unlikely it may appear that it will be successful. Sometimes unlikely things can work in a certain way if we can find the angle on it.
Don't put a man down for trying. It's all good, even if just to make certain that that way won't work.
