For the idea to work for cooling, he would need to expand the air in a different location than it was compressed in. (I wonder if standing waves exhibit this effect?) IF it works out that this is possible, I imagine it would be like standing in front of a CO2 fire extinguisher (gets cold as pressure is released).
- pontifier 8y agoThis is essentially what the pressure waves would be... mild compression waves would travel outward as you pull a cylinder creating a vacuum. You've compressed the entire atmosphere slightly, then you let some air expand back in through a small nozzle to fill the cylinder again. Then you open a port and push the air back out without changing it's volume, and close the port to complete the cycle... It seems like there's got to be something wrong with the concept, but I can't put my finger on what exactly.
