PennyWorld, like everone else, I've been trying to figure out the problem with CTKH. I think I know what one big problem may be. Most corporations will not buy products (component parts) that are not Patented. This because of potential patent infringement litigation. I've run into that problem myself. HF will not patent his product because he is affraid that China or someone else will steal his invention. I think he may be trying to develop a complete product using his component parts which would alleveate the patent problem.
