Want to know how we will live in a non powered future? Read Farmer Boy by Laura Ingalls Wilder.
In the non powered future the way hair will be cut will be with scissors and a comb and possibly a bowl. I saw these now powered trimmers in the movie The Great Raid. The movie was about the US Army Ranger raid to rescue American prisoners from the Japanese prison camp in Kaubutan Philippines during WWII. The one soldier was a mortician that fixed dead people’s hair, his friends thought is was funny that he was trimming their hair.
At the gun show this weekend I found a pair of trimmers for $15. Here they are.

Hair Clippers
Cool huh?
I have a lot of other non powered things that I have been collecting and I will put them on my new blog. See the “My Other Blog” link on the right.
