10-20 years down the line do you think I could replace a body part with a biotic improved version? Would you?

  1. Like the Terminator?  Probably not.

    The BIGGEST problem is power.  We just can't make batteries that are small enough but produce the HUGE amounts of power that motors would need.  Enough power means beig and heavy batteris.  And right now there is just plain a chemical limit to how much power we can produce from batteries.

    In IRON MAN, Stark developed a miniature nuclear reactor to power his suits -- that's the lighted thing in his chest.  It is supposed to be a miniaturized version of that big power thing that exploded in the end of the movie.

    But the probloem there is that it was a FUSION (combine the atoms)reactor.  Currently, almost all reactors are FISSION (split the atom). We haven't got a good working fusion ractor -- yet. And certainly not one small enough to fit in a man's chest!

    And the other problem is in the case iof bionics, how do you control them?  The terminator has a special Artificial Intelligence brain -- but that takes so much processing power and computer memory!  Right now, to do what the Terminator does would take ROOMS full of computers.

    But that was what CyberDyne developed -- a small, very powerful microprocessor.  That was what they were unting for in Termionator 2.  But of course, thing like that don't really exists. And probably won't.

    The real application is interfacing nerves to computer circuits and mechanical devices.  And scientists are trying to do that just now.  i saw an internet article that showed a small experiement where a little motorized cart was 'run' by mouse brain cells.  

    If we could somehow get our nerve cells to control machines, we COULD make arms and legs that work like the real thing, and allow amputees to walk and run and type and play piano . . . Scientists are working on it, but that kind of stuff is probably 30-50 years away from being useful.


  2. There were the monkeys which fed themselves with a bionic arm, but as already answered by others, power is a problem.  

  3. No, can't do the "super human" strength things because it would transfer too much stress to other parts of the body. In other words, if you have a bionic arm that could pull 10,000 lbs., you would rip off your shoulder where the arm is attached.
