Thanks for the link it really looks interesting. If it actually works, it would really be an incredible breakthrough. It looks like almost nothing at all, so small. I guess it works on the same principle as the 'fanless', silent air filter they used to sell at The Sharper Image. I can't fathom, however, it can supply the volume of air needed in a single breath, but then again, I'm not an engineer...
The website does say it only is for one night's use. That's a bit much for me, tossing out something electronic every day of the year. Contact lenses, I could stomach doing that daily. Even coffee pods, if I could recycle them properly. But electronics, um, it would be hard to do. Maybe once a week, but not daily.
They will need to change the design to allow recharging, otherwise I would only want it for travel only, or emergency use. I don't know how that type of business model can work otherwise.
