Can I suggest an improvement? Vacuum is also a great isolator and combined this with an internal hot air balloon, the inside can be made lighter by using hot air with the same pressure but lower density. The air is way less dense in the stratosphere so there must be some kind of equilibrium that can be obtained that once an object is that high it requires little energy to keep it there. These kind of blimps only get more efficient the bigger they get.
I also have an idea for active vacuum isolation for housig, much better lifetime than passive vacuum panels. Too bad no known takes my vacuum engineering serious.
- SnowHill9902 4y agoThe answer to why none takes your vacuum engineering seriously is ironically in your username. Vacuum is a good thermal conduction and convection insulator in theory, but as soon as a little bit of moisture leaks into it, it’s toast.
- KrugerDunnings 4y agoPlease don't judge my theoretical ideas by your low engineering standards.
- jagged-chisel 4y agoI think your detractors are reading snark where humor is more likely.
- nickparker 4y agoActive vacuum insulation isn’t a thing because you need high vacuum to reduce thermal conductivity at all, because mean free path and therefore specific conductivity grows at the same rate density decreases until mean free path exceeds the characteristic length of your application. Also, modern VIPs have decades of life if installed properly.
