In 1998, Robert A. Freitas published a detailed design of an artificial red blood cell with several useful properties, (stores 236 times as much oxygen as a natural red blood cell, indefinite shelf life) but with the minor downside that it would require atomically precise diamond fabrication to actually construct. https://www.tandfonline.com/doi/pdf/10.3109/10731199809117682 https://www.tandfonline.com/doi/pdf/10.3109/1073119980911768...
Was that paper a waste of time?
- causi 4y agoIt's always shocking to me how inefficient hemoglobin is. Less than 1/500th the mass of oxygenated hemoglobin is oxygen.
- neltnerb 4y agoI'm similarly always a little surprised at just how inefficient photosynthesis is compared to a solar cell. Once I realized it was more than an order of magnitude I lost a lot of interest in biomass (much less ethanol) as a fuel source for sure...
