Wish I had mod points for this comment. You nail it pretty nicely, anyone concerned about Alexa security (which I believe everyone SHOULD be) is best not bringing one into their home.

What about using nuclear (reduced life cycle greenhouse gasses, yes, we need diesel to mine uranium/thorium) with a closed loop system through the heat exchangers? The problem is plants that tap well, river or ocean water, and run it through evaporative cooling towers. This problem is created by the economic advantage granted to building gignormous plants that can't dispose of heat easily to their cool heatsink (thermodynamics baby) in order to do work. Now about a small nuke plant like the naval reactors that doesn't generate the enormous amounts of waste heat?

Any decent industrial electric motor shop should have a VPI tank. I think this one is big enough... http://news.thomasnet.com/fullstory/818736 (10'x10' VPI tank)
