Yes, "...IMO the DC motor with a permanent magnet is better,,,YES. That's why, IMO, Tesla will be driven toward cost effectiveness to survive, which means "magnets" for energy regeneration, and a step toward perpetual energy use. I'm a Reliability Engineer by profession and a physicists by passion. So, RE's will eventually replace the lithium ion technology. I wish they would have me on staff to help them, but being 70 years old, they would probably just ignore me like my Son does.. :)...They will see it, you'll see.
This is partly true. The point, "...because they need our products..." is the point. Eventually, cost effectiveness and logistics considerations will, IMO, drive production more toward DC motors. The bottom line is the bottom line.
The DJIA doesn't have this message board, so let's put the message here. It really looks like this could be the top. The DJIA upper trend line from 1999 puts us right at a top, draw the line yourself with a ruler. I'm betting on a good correction from this area. It's FAZ and TZA for me.
