The "Black Helicopter" Could Become a Reality

   A new rotor blade design, the tip shaped like a gull's wing, operates at such low noise levels (3 ~ 4 dB) that this nightmare vision could actually come true.

      This is really interesting.
      
      Why is it a nightmare vision?

         It is for some. Silent "black" helicopters spying on others.

            But isn't it no different than having satellites on you?

               A satellite has to move around the earth. The geosynchronous types are just too far away to do any decent spying.
               
               In a way I'm joking. The "Black Helicopter" was a paranoid fantasy of the far left and far right (which oddly resemble each other when they get that extreme) for years.
               
               Today college engineering students are making small, light flying machines just slightly larger than insects complete with autonomous control, small cameras, and near silent operation.
               
               Still, the announcement of this rotor (4 ~ 6dB is VERY quiet) got me thinking about all of the "black helicopter" scares of previous years. Hey! It could now be a reality.
               
               Here's one that really fascinates me. Because this machine has a single blade, processor control of it's pitch has to be quite precise.

   They look very cool.
   
   But the reality is quiet or not it's just another waste of money ready to crash into the mountains of Afghanistan.
   
   The United States spends HALF of all the World's Defense spending.  We have enough nuclear bombs to destroy the world 1,000's of times over.
   
   At some point wouldn't you think that it's time to really look at what is going on and not look at how it is benefiting the Wealthy, but how it is benefiting all of mankind?
   
   People are suffering and the United States just goes on building the War Machine.
   
   Where is the Clean Energy?  Maybe these could be flipped on their side to create noise free wind power.
