Apparently they have a working device that has been and is being tested by 300 engineers, and they started a public speaking campaign in early 2009 in the Middle East, then are moving to Europe in the summer and the USA this fall.
I’d been following these guys a couple of years ago, as they were apparently ready to go public, with a robust model for demonstration.
They were to display their engine in London, and a chap I sold some orgonite to was going to take a piece along, but the demonstration device failed to work so they called it off, which was a shame.
Like with all these devices, I hope it is simple and/or affordable so we can all buy/make one.
