It was an entertaining rant.  I hope his point about the need for reliable measurements gets through to at least some people.

I have subscribed to this guy for years and he is excellent.  Man, I would hate to be that poor bastard making those stupid claims on his blog, ha ha.  We obviously have many circuits here that are far more efficient than that guy's, and we know that they are not "bending the laws of physics".

I hope MileHigh sees this video, he will love it.

Of course, I suppose there will be some that claim that Dave is a paid shill for big oil or something.


Thanks for posting this TK, I have so many subscriptions over at Youtube, it might have been quite a while before I saw this.

While the ranting was very entertaining, the important part of the video in my opinion is the _process_ :  Dave redrew the schematic according to an easy-to-understand layout convention, he analyzed the circuit using standard engineering principles and knowledge (referring to data sheets and other solid information), he predicted the waveforms and other readings, and then he went on to test his predictions and demonstrate that his predictions were correct by actual measurements.

I thought that it was instructive that he wrote down the bullet item claims and then showed how almost all of them were flat false.
