Airing raised $928,778 from 9,338 people - it's done

And some of us have indeed studied Airing's FAQs and do care about new inventions and have a background to comment on this.

Comparing the power requirements for this project with a hearing aid is a non-starter as they are not even close. I have in the past designed and built hearing aid's and yes I do know for sure.

I have used and tested most commercial air moving technologies as it relates to cooling LED lighting which requires far less air movement and no pressure to speak of. Even then the poser required totally negated any savings that could have been gained buy using LEDs.

There is some very basic engineering that someone on the team should have done. We know the volume of air required and at what pressure. We also know how fast that air pressure must change. From this someone should have calculated just how large a micro blower or how many micro blowers would be required and from that what power would be required. From that it's easy to verify if ANY battery technology can supply that power, in the size they are expecting, for 8-12 hours of use.

They should have done this before asking for funding. They should have been able to do this in one day.

Inventing and people that resist change is one thing, people that wish and dream without doing even the simplest math is a different thing.
Sometimes you do have to build to test and sometimes you just need a spreadsheet to do some calculations.

And some of us have read and understood their FAQ's. We're still very skeptical.

Obviously, you haven't read this thread.

It is used in many hearing aids, in a full-featured recent design like the Phonak Audeo V life is about 10 days with the aids off during sleep hours. Airing uses much more power so expect only one night's life or about 1/20th of the hearing aids. (It is unlikely they'll develop rechargeable in this decade, hearing aid manufacturers may fund such battery technology (the limit in both uses discussed here is battery volume for desired device compactness).)

Blowing air takes a lot more energy than amplifying sound in a tiny hearing aid, producing enough sound to be heard when it's inserted directly into your ear. My CPAP takes about 10 watts to run it. The largest hearing aid batteries seem to be about 700 mAh. That's about 1 watt hour. In concept, it would run my CPAP about 6 minutes. You might stuff several hearing aid sized batteries into the Airing, but you still wouldn't get a lot of run time.

You'd have to assume the "micro blowers" are much more efficient than the current design of blowers to get a decent run time. That might be theoretically possible, but I'll need to see it first.

Zinc air batteries also tend to produce only very small currents due to their need to absorb oxygen through a membrane to power the reaction.

Heartless would be encouraging false hope when there are people who need to make their current CPAP therapy work now. False hope kills.

This is a neat idea. There are several things you could do with such a device. I hope it works.

I think the guy doing this is honestly trying. I don't think the battery or micro mechanical technology to do it will be available anytime soon. Not by a LARGE margin.

I hope I'm wrong.

In my post I did point out that the battery was what I felt was the weak spot, which is what makes me take a wait and see attitude with my google news alert keeping me apprised as time goes by. If it happens great if it doesn't, perhaps something else more groundbreaking than current technology will.

Before anyone else becomes indignant with my post, and perhaps wishes to defend their positions, let me say my intention was simply to acknowledge how I felt with many of the comments on threads on this device. Seemed like there was a lot of ego in them more than the desire to protect the folks who come here.

I am not well enough, nor do I wish to quote and respond to each and every prolific writer who has commented, or will do so.

If you feel you did right by the others who have or will read your accounts, than that should serve you well enough. No need to defend your intelligence or manner.

If the Airing device shows anything to me, it is not "how many idiots are born every minute" but rather, how desperate so many still are to for some kind of simple and more comfortable cpap technology to come along. My 2 year experience hasn't led to a workable solution for me, but I do wish there would be a significant breakthrough beyond what there is.

I'm still looking,, and perhaps one of you, may be the inventor of it

Some people are desperate, others are ignorant... both can be cured. Stupidity is forever. This is not an easy journey, I have suffered a long time before finally giving in to the idea of sleeping with a mask the rest of my life. My 2 stage sleep study was the clincher, I felt so much better after having been on CPAP for a few hours, I am desperate to get my machine. (The world of insurance and health turns very slowly.) The fear of this is real to many people, and that makes a fertile ground for hucksters. Myhope is that this is not true for this, but reality tells me it probably is a scam. Only send money you can afford to lose, and have very low expectations.
