Storage was my first thought being the packrat I am, when I first found out how easy this was to do. But the thought of trying to DIY compress gas. No thx. There is a guy in Hopewell NJ. that stores like 3 months worth of gas at a time to power his home. He does this in ten 1000 gal. propane tanks, so guess he's not a under pressure guy either. Daniel Nocera of MIT was asked at the end of a lecture about compression and he said he had no interest in getting involved with that process as it would involve special equipment and diaphragms for compression.
