There is breathing going on here so is there any chance that the breathing out could help recharge the battery in a similar way that a hybrid car charges your battery when you brake?

I also don't think it is 'disposable'. I think it is recyclable and from what I've seen the $3 is dependent on recycling them.

No. To be effective CPAP has to be continous, even during the exhale.

Most of the machines sold now are continuous, but not at constant pressure. Mine's set to detect apnea events and adjust between 5-15 for pressure and to adjust that further based on exhalation.

Yea, for sure.

Mine can do all that, but I actually have it all turned off...I find I have a much easier time getting and staying comfortable that way...every time the pressure changes my mask would shift...at a constant pressure I can get it "just right" and it doesn't leak at all and I find it easier to fall asleep as the pressure points don't shift around.

Ah, so that's the C in CPAP (continuous positive airway pressure)
