Was also thinking about another sky train parallel to current one.
High speed trains between major cities on prairies. Edm, Cal, Med Hat, Swift Current, Regina, Saskatoon, Winnipeg, Yorkton, Brandan etc.
Winnipeg to Thunder Bay,
Montreal to Toronto, Ottawa,
Northern On to southern Ontario
Along these routes solar and wind farms can be built, to supply energy the train line etc. also communications like fibre optics.
Not only in the future will we need less transportation that burn hydrocarbons we will need a cleanner electromagnetic spectrum (radio waves). So sending info through fibre can eliminate some of that...
Right now the world is stuck in Reverse Gear when it comes to planning our future and betterment of our next generation. As the video says we been stuck on gas and car (pollution given us by some major corporations - Standard Oil, Goodyear etc) since the 1950s, which is one of the reasons the world is having a problem with greenhouse gases... like CO2.
