Wouldn't it be a trip to find out that we've been doing it wrong for hundreds of years, and that all this old technology is sitting around in plain sight, not being used? I've been having a lot of fun with the idea, coming up with all kinds of things. I really think some clever kids are going to demonstrate this forgotten tech to the world soon, but also I like knowing that if times get tough, some inventors might be able to bring a little light and warmth into any shelter.
