$34-billion annually for DIALYSIS

Why don't we have a working #artificial #kidney?

It should not cost even $1 Billion dollars to produce a working artificial kidney.

We already have the technology in the big machines. Historically, it only takes a couple decade or so to reduce things building-size to pocket-size.

We've have room-size dialysis machines since 1913. 107 years later, we still do not have a pocket-sized or transplantable devise?
