I can't decide if this is a brilliant idea, or a stupid idea. I'm leaning toward stupid. It probably has the desired effect during winter, but it's got to be way more expensive than normal (and still very effective) methods of insulating your home. Seems like it'd be miserable in the summer. The only thing I like so far is that the exterior of the house would theoretically stay nicer, longer. I'm only a few minutes into the video right now, so sorry in advance if it turns out to be 20 minutes of pure stupid.
