Let see if I have understood something about "respirocytes": They are
micrometer sized spherical diamond tanks able to store gazeous oxygen at high
pressure with the help of a centrifugal pump using a 10 nanometer rotor...
First, why diamond? graphite sheet are nearly as strong and there is a well
established technology to make them in the bulk.
Second, What is a submicrometer gas? At that scale, surface effects are
dominant. What about using capillarity to load a cylindrical bottle made from
a nanotube?
It seems that has been done for hydrogen, why to build atom by a atom a
diamond structure? Diamond or not, carbon and high pressure oxygen are a
noxious mix. Do you really would try to make such a complex, unstable, costly
thing when fixing an ahemoglobin molecule to a carbon nanotube would do the
same work at some $/kg?
