Needed technological advances

In keeping with Instapundit’s list of needed technological advances, here are four of mine

  • Cheaper Carbon Fiber materials – Much lighter and much stronger than metal, but at the moment, much more expensive. If this cost could be brought down many other technologies become economical, electric cars, prefabbed buildings, small scale wind generation, etc.
  • Smart traffic lights – while these do exist at the moment, they are not in wide use. I live in a traffic-light heavy part of the city. I also do most of my car travel at non-peak hours. I still stop at most of the lights for no reason whatsoever. Smart lights (these exist already) would sense if there is a car that needs to get by and turn green (assuming there was no competing traffic) and then snap back to it’s existing cycle.
  • Decentralized electric power – To my knowledge, the main power grid has not been modernized, ever.
  • Cheap wholesale medical testing – imagine just having a machine in your home that could analyze your blood or urine every day or week and test it for the top 50 detectable problems. If all of these problems are caught at the first opportunity, how many lives could be saved?
