Compressed Air, Your Lo-Tech Friend

• • • — — — • • •

While we're on the topic of renewable energy, I'd like to segue into a little rant about compressed air. Don't forget what you already know! Compressed air is an incredible renewable resource. Compressed air guns can kill, and though you normally get one shot, that one shot doesn't have the bang of a normal gun. And you can charge the air container with a bike pump. Do you know what else you can charge an air tank with? A windmill. There are some farmers in the Midwest who use windmills to charge compressed air tanks. They then use that air to run water pumps in locations too remote for electricity. So chew on that little chunk of ingenuity for a bit. I'm not saying it's genius, okay, actually, I am, but my point is, in a post reliable-electricity world, compressed air has a whole bunch of reasonable applications. So strap on your stupid. If you think about it, you already know a ton of things you can do with compressed air.
