Re: Nanotech for astronauts
"Such technology could be expanded for such tiny machines to act as doctors. Perhaps nanobots could be made that could repair the body at the cellular level. "
Yes, this is due to happen just 2 weeks after we get that cheap fusion power. :)
The nanotek for blood cell detection requires no complex nanos, just small ones. The problem with the nanobot doctors is not even nanotek. We still do not have a clue as to how to develop a macroscale clunky robot that perceives and interacts with its real world surroundings at the intelligece level of a gnat.
