The wimpy power grid! Low pressure air for little jobs. I pumped water 6 ft high with 0.2psi!

So I am not talking a 0.2 psi grid.  Anywhere from 1 to 4 psi should work for the little jobs.  All  you have to do is make feeble wind or water or solar panel or Stirling engines to power the  pumps and the pumps are just a couple of ft of tubing!  So, 1 psi is nothing! We should be able to make it in all sorts of ways.  My air comes from a 3.5 Watt bubble pump until I (or you) figure out how to run a tiny compressor off my 15 Watt solar panel.    I have a few demo videos including the one here
