I wonder what it would take to get us to the point where we can oxygenate sufficiently without needing to use our lungs at all. Tons of applications there.

I think something along these lines might be possible in the far future.

Imagine using a battery and a small wire to directly enable respiration at the cellular level rather than using oxygen at all.

I can see this greatly facilitating a host of activities on other planets or in space.

That already exists. Surgeons have been using cardiopulmonary bypass machines for years.

What would you replace the lungs with? The space could probably fit a battery and M1 Mac.

You would need to replace them with something that could effectively replace the rectum.
