When I saw this thread I wasn't going to post but I liked the idea from a save some $ stand point but wanted to say that from my experience propane gases off at ~62~64 PSI (as measured on my gauge once about 10 yrs back) and using one of the GAS GRILL tanks would not be wise to COMPRESS them to the relieve valves MAY be set to 150 ~ 200 psi but those normally only activate in the event of a fire or error when filling! there are many warnings about people using these to make "remote Air Tanks" or "Portable Air Tanks" and then having them rupture when filling... SO it is not wise to try & do there types of things.
you said you used 100 lb tanks and it only lasted a few min?? sounds about right to me as LP is
1. a liquid, which changes state to gas and
2 propane has a lot more available BTUs per CF than nat gas.
it was an interesting IDEA though there are booster pumps that use the compressed gas to over compress it but you need to refrigerate the gas to assist it in changing states from gas to liquid if I'm remembering stuff correctly. while simply compressing it it is possible but uses a lot more energy than dropping the temps on top of compressing it.
