[RE-wrenches] Enphase and Tesla Powerwall

[Mark Frye]

Uh, Looking at what is happening with Tesla's share price, I am not sure 
I would want to be "investing" in the products of the neglected solar 
division. With Elon alone at the wheel , the Powerwall et. al. might go 
the way of the Dodo before too long.

I have been working lately with folks who have moved on from the 
vestiges of SolarCity. They don't seem to be very impressed with what is 
happening there, at  least not enough to stick around while the division 
molders under the jaundice eye of the visionaries.
