No worse of all is above around 15,000 feet there is not enough O2
partial pressure to let this already power hungry, expensive and
cumbersome (for our needs) product work.

It is a solution looking for a problem. Maybe in GA where there is no
local FBO/refill station but even then it'snot hard to maintain your own
O2 refill cylinders. I am seriously surprised the manufacturer is
marketing this to the aviation market.

This oxygen system looks interesting but is only certified to 15k
and
battery life is only 6 hours. It would be nice to do away with
filling
bottles. Does anybody know of any other systems available or on the
horizon that would be more useful to glider pilots?

And worst of all, the operating temperature is 5C to 40C, which isn't
much use at 15,000ft if the temperature is 0.
