I think that you can do much, much better than this by using a rough vacuum filled with powder or aerogel granules. I actually think that you can make a tank of diameter only 10 meters that would last for centuries. Such a small tank would probably only cost $200,000 or so to build, yes? The main issue would be maintaining the vacuum, but it would only need to be a rough vacuum (1/100 atmospheres).
I’m actually seriously considering pitching this idea to Ben Best when he comes to the UK in 15 days.
