You know, I watched just about every video clip associated with that thing and am still shaking my head. One thing that I do have to ask though: The first one that I watched was the one where they had a typical electric KWh meter connected and they had a clamp-on meter watching the motor's wattage.
How did they manage to get the clamp-on meter's reading to change? Was it a case of smoke and mirrors? I'm not saying that I believe this junk for one minute, but their demo sure does look believable. It's no wonder that they are selling them.
Ed, How do you know the motor's output isn't changing? If they are showing a reduction in real power, it is most likely due to reduced output on the motor.
Show me a test using a motor connected to a dynamometer. Otherwise, it's like the magic disks they used to sell (do they still sell them) that would reduce power consumption of light bulbs ... by half-wave rectifying the power and reducing the light output!
People will always find new ways to sell snake oil ...
