Zen, TKO definitely gets a fee for every installation,I believe it's $5000, plus a monthly fee from every substation where they are asked to install their technology which takes about 3 hours. I will check out these numbers tomorrow afternoon. There are 70K substations in the USA & 200k world wide. So there are 270,000 substations world wide, enormous potential obviously. GE also gets a fee from every substation since many of them are independently owned by hundreds of electric power companies.Many substations have already been installed as a TKO-GE test. When the 1st one was installed GE executives were there & openly stated "we are in let's go".Ron Pickett repeated this at financial forum in NYC ,he referred to this as an electric utility test. I was at the forum. Good Night, Walrus
