Tlum 12 | 167 31 Jul 2022 #1Since people were told the Earth is a globe, how about this - build a railroad from the North, eg. Sweden or North of Poland down to South, eg. Italy. The train would use no energy because it would just slide from the top to the bottom of the Earth, like on a big ball. It would save a lot of energy. In fact, the heat energy produced by brakes could be stored and sold.Opinions?
