New Device - hype or excitment?

Yeah it is kinda interesting although I've read over on ScubaBoard some emails that someone posted going back and forth with the inventor.  Apparently the air it extracts from the water contains like 34% O2 so it's technically like breathing nitrox which is interesting.  Seems like you'd need a helluva lot of battery power for it to be practical and even then...I think you'd need to carry bailout like a rebreather.  Who knows where it will go though.  :-\
