True on the expensive side, was just giving an alternate. I run my reactors in the basement of my house (personally) and babysit them the whole time they are on. I charge up a bank of batteries and run the house that way. If I'm away from the house, I set up a small solar array, charge a battery, and run off of that as much as I can. I have lost a couple of houses to curious children, and switches mistakenly left on this way... Hmmmm... You have a point. :D
