Century old patents for alternative energy solutions. #awesome

I love this…

Alfred Clark patented a labor-saving brainstorm in 1913 — a churn operated by a rocking chair.

Here’s one solution to the energy crisis: enlist the children. Julius Restein’s “device for operating churns,” patented in 1888, will exercise your kid and produce loads of delicious butter at the same time.

It also works with washing machines.

Both examples courtesy of the awesome futility closet.
