Google searches can be a scary thing....sometimes like giving a kid a loaded gun. It is important to have a little experience to understand things and be "safe".
1) there is no patent on this "tower", that 1975 patent expired in 1992 without a single tower ever being built.....and none since for a total of ZERO!!!
