I really do love lighter-than-air craft.
There is something elegant about them.
As a kid, I read a book about a bunch of people who lived on an island, and all had balloons of various types for transportation. I can't remember the title, but it may have been THE TWENTY-ONE BALLOONS.
In Wisconsin, we have the annual meeting of the Experimental Aircraft Association. I wonder if any of those guys ever made their own blimp?
I remember one of my older brothers building a tissue-paper hot air balloon. It was powered by a cotton ball, soaked in alcohol, and lit on fire.
Come to think of it, ANY metal mixed with ANY acid will make hydrogen gas as a byproduct. I wonder what it WOULD take to make a small blimp...
