Six or seven years ago, without knowing more about the Nest thermostat, I would have commented something to the effect that, “It’s a stupid thermostat. How brilliant could it possibly be?” Once I got my hands on an iPhone, I could see what the deserved hype was about. I expected something similar from Nest since it was developed by a former Apple guy, who I later found out led the development of the first 18 generations of the iPod and 3 generations of the iPhone.

I don’t know much about renewable energy in the form of photovoltaic (PV) electricity generation, other than its efficiency is about 10% from solar radiation to electricity. I’ve collected a mélange of articles that each seem to have interesting, if not humorous, short stories.
