The clever part is that the dome is incredibly light. It thins toward the top, where it is taking less load, and uses empty jars in the concrete to lighten parts. The relatively thick heavy walls are enough to hold it.
Rebar generally reduces the life of concrete - almost all concrete failure is due to water getting into the rebar, creating rust which expands and cracks the concrete. A lot of the ruins of Greece were damaged by…
The airlines would demand a 3hour checkin for each train to compete fairly.
In the first millennium there was no airport security and a large number of Viking raids on Britain. In the second millennium airport security was introduced and many fewer viking raids took place In this millennium…
It's a dome - domes are in compression - in compression you don't need rebar
There may be a good reason to avoid using batteries - it takes rather a lot of AAs to move a train
True, but the article implies that "economists all agree on these things, economists are experts - therefore these things are correct" But the same responses would come from US politicians of both types - would Swedish…
