Has anyone investigated the use of an oxygen generator rather than carrying an O2 cylinder?



According to this study from sea level up to 18,000 it seems to work. http://oai.dtic.mil/oai/oai?verb=get...er= ADA371747



"We conclude that from sea level to 18,000', molecular sieve based O2 concentrators are capable of providing medical grade supplemental O2 for at least 8 hours."



Pricey but for those the fly with O2 every day then over the long term it would be cheaper as there would be no refills. Here is a unit for $3K. http://www.emedstores.com/xpo2-porta...extra-battery/



Might they be less dangerous in an accident? Is battery power an issue?

A couple of good articles on O2 from Mountain High.

O2 can be purchase at many industrial gas outlets and is relatively inexpensive. ABO is the same as welding O2 but usually is a little more expensive and comes in a bottle marked ABO. Large bottles have the downside that you usually have to rent them and you need a transfill system to fill the glider bottles. If you take your glider bottle to the outlet they will check the test date on the bottle, if out of date they probably will not fill it, so be aware. The bottle test date is not an FAA requirement. It is regulated by the DOT.
