Wouldn't that be a dream come true?

Except that it's not possible, it would be very cool.

Just for comparison, a normal CPAP machine requires a 100Ah deep cycle battery, physically, a little bigger than what starts your car.

There's no way this thing works unless it contains a power cell from the future.

Flux Capacitor. Proven tech I saw it in a movie.

Quote:Large zinc–air batteries, with capacities up to 2,000 ampere–hours per cell, are used to power navigation instruments and marker lights, oceanographic experiments and railway signals.

Primary cells are made in button format to about 1 Ah. Prismatic shapes for portable devices are manufactured with capacities between 5 and 30 Ah. Hybrid cell cathodes include manganese dioxide to allow high peak currents.

Button cells are highly effective, but it is difficult to extend the same construction to larger sizes due to air diffusion performance, heat dissipation, and leakage problems. Prismatic and cylindrical cell designs address these problems. Stacking prismatic cells requires air channels in the battery and may require a fan to force air through the stack.

It has to be safe enough to touch our skin (or even mucous membranes in the case of pillows). And it has to be stiff enough to not flap outward with each exhale when we breathe (for FFM and masks).

But as for the Airing, I call bull crap. It just is not possible. And a Google search on the zinc-air battery makes me believe they are full of even more bull.
