Energy, Water & Transortation Solution

Here is an idea for a combined solution to global warming, fresh water and transportation.

Instread of traveling around the planet, we should travel through it. This would be done in subterranian vacume tubes. 

The tubes must be cooled with sea water in order to prevent the tubes from melting from the subterranian heat. 

The sea water becomes stream, and powers turbines that supplye electricity. The steam is sterile and desalinated.
