Robert's Rocket Project - Home I believe Thomas Edison said, "I have not failed. I've just found 10000 ways that won't work." Well, I've found at least one way to build a flight weight tank and a valve that don't work at cryo temperatures. I ran cold tests a couple of weeks ago with LN2 and the tank leaked like Niagara Falls around the seal when pressurized. I knew it would leak some but I didn't expect that much. So, it's back to the drawing board for the LOX tank.
