Living in the Age of Jetsons (minus flying cars)

Reposted from i.e., the Center for Energy and Environment's Innovation Exchange blog -- http://mncee.org/Innovation-Exchange/ie/In the early 1960s, "The Jetsons" treated TV audiences to a cartoon future filled with jetpacks, flying cars, and helpful robot maids named Rosie... Swap Rosie for Alexa, and 50 years later we're edging closer and closer to realizing that colorful vision of the future. And amid all the new high-tech…See More

"Thanks for letting me know about that video. I hadn't seen it before. It is a good parallel. Now we need to figure out the converse. "

"Lester, I think you answered your own question, nope, we haven't figured out the convenient and efficient way yet.  Have you seen Corbett Lunsford's If Cars Were Built Like Houses? A good parallel. "

"Sweet! Will the industry listen? I don't see how Nest plays into this. Isn't it a black box? We use Ecobee - it allows us to see how equipment and enclosure perform together, and when occupants are uncomfortable through logging…"

hi Les, it has been a long time, but "ole" friends just bounce around and eventually come back your way. I watch the VOLSL on a big screen at home these days, and &*%$###@ to Kiffin. We're having a slow year, but at least we're setteling in for better days.

Take care. Pat.
