The French came up with a compressed air (very small) car about a decade ago.

They claimed it would be cheap and easy to fuel renewably with electric compressors powered by renewable energy sourced (PV and/or wind) electricity.

Tata motors is licensed to build it, but apparently they haven't decided to build it.

Also, don't forget that every mechanic out there, who has a shop and changes tires routinely, uses compressed air powered tools.

Compressed air power has its niche in civilization. I don't think it will ever go away, simply because it is so cheap to store energy in the form of compressed air for immediate, on demand use, even if compressed air cars never become part of the transportation picture.

Interesting.

I have a big compressor, but my wife made me take it out of the garage because it was really noisy. It's in storage. I have a few air tools, from the days when I thought I wanted to learn to paint cars. More recently, all the power tool makers have come out with alternatives to air tools. I have an electric impact wrench, for instance. When I was young there were no electric impact wrenches, or at least I never saw one.

The high speed air turbine is still my default dental drill (handpiece, we call it), but they have good electrics on that too now, which some people prefer.

The Amish use windmills to compress air, which is kinda cool.


Agreed. 

And that sound of that high speed dental drill is something no person who has ever been to the dentist can ever forget!  ;D

I've often wondered why compressors are so noisy. Sure, the physics involves all the vibration frequencies that are blasted in every direction from air that don't wanna be compressed, so to speak, but there is a sneaky way to get around that. I know they use that with mufflers. As you know, if you can get two sound wave frequencies to interlace a certain way, they cancel each other out. If they can do it with car mufflers, why not with compressors? If you put your thinking cap on, I'll bet you can make your noisy compressor purr like a kitty so your wife won't ban you from using it.
