If I had this device. I'd walk into the physics department at Cambridge University and wouldn't leave until they told me why I was wrong, or I convinced them.
Which he has already tried and been told its none sense because it doesn't conform. But it still works....
I wouldn't be making youtube videos, or trying to make a device with some random professor in China.
The video was actually made for his site and re uploaded on youtube.....
