This is the sort of thing for which Glenn Reynolds would say “Faster, please”:

In my new book, I have a storyline involving one of those Edison-level geniuses who pops up every once in a while and remakes some major aspect of human life. In this case, the character invents a package that involves photovoltaic paint and a lightweight battery capable of storing up to 20 kiloamphours of power, a package that weighs less then 40 pounds including batteries and the PV paint. The notion is that you could spray your roof — or your entire house — with the stuff, hook up the battery storage system, and remove yourself from the electrical grid entirely.

That’s a heck of a charge. Assuming you need 100-amp electrical service, a battery this size could run things for a week or so without any input from the solar grid at all, assuming temperatures more like San Diego than Saskatchewan. (At least, this is how I remember the math: 20,000 Ah/100 A = 200 hours.)

This, of course, assumes they’d actually let you do that:

I hadn’t considered it for the book — the wrinkle doesn’t really fit into this part of the story, although it might figure into the sequel — but that sort of development would likely be violently opposed by the powers who control the grid in all its manifestations. It moves the command Let there be light from the hands of all the various collectives that make up the current lines of supply into the hands of the individual. As such, it would be a deadly threat to those who wield those reins of power and control today.

Faster, please.

    Yep, about a week. And for cloudy climes or seasons, you might need a couple of them, and a really fast recharge time.
