Considering the US military’s budget I don’t think that’s substantial

ErythroMer is constructed from “recycled” human hemoglobin—the protein responsible for oxygen transport within red blood cells to the body’s tissues—enclosed within a membrane to resemble a miniature cell.

I recall learning that poop is brown due to a high content of dead red blood cells. They have me awfully curious what kind of “recycling” they’re doing.

In the 80s I had a non-biologist friend who told me about something in development which could act as a blood replacement. They wanted to fill a swimming pool with it, sit on the bottom of the pool, and meditate. I suggested the viscosity of a pool filled with anything like blood would be a whole lot more viscous than air, and so would require a lot more muscular effort to move in and out of their lungs. And so the experience wouldn't be as relaxing as they thought. All these decades later, and researchers are still working on it.

Liquid breathing is definitely possible, you’ve even done it before (in the womb), but it’s probably not possible with something like blood. I think your friend was probably mixing up two different concepts

I actually thought this was something done and done like decades ago. I think it just substituted for sera though so maybe this does the red blood cell thing to.
