Today, we’re talking air power.
Compressed air is, in some ways, one of the best-kept secrets of the clean energy movement. I don’t hear it talked about much, and frankly, that’s a crying shame. Compressed air can be used to run not only any tool you can find in a machine shop, from drills to power hammers , you can also use it to generate electricity, or even for refrigeration.
As power storage goes, it’s not the most efficient way to do things – batteries can hold more power for longer, hands down. What it IS, however, is easily accessible to anybody with a bike and a cheap air compressor. It means that you can store energy without having to be a chemist or an engineer, or even much of a maker.
This is energy storage for the masses, and energy is key – you can use it to do just about anything.
