I'm wondering how big of a compressed air tank can I bury in my yard? As for compressors, check out the California air compressors. I used to have a Coleman that was super noisy. I picked up a California Air air compressor at Home Depot that is so quiet my wife on longer jumps in fear when it turns on. Alas, I would think that instead of glide DC to AC to to a standard air compressor, it might be better to go DC directly to a DC air compressor to air pressure, then convert that pressure to AC.
