Wrong. Just been studying Hydrogen, Fuel Cell, Ammonia Cracking, Solar to Hydrogen to Energy, Methane gas, Natural Gas to Hydrogen and many other emerging technologies. If you get a chance look up Dr. Swains @ U-of Miami work study on Hydrogen and you will learn some educational stuff about Hydrogen and where we are going. Hydrogen and Fuel Cells have been used by Nasa since the 60's with no problems. Hydrogen is the #1 element and we won't run out of it in our lifetime. I hope you get it a little bit now. Research the rocket fuel used on the exterior of blimps and you will be surprised to read about the same blimp you mentioned. Fuel Cell Doug Out.
