I'm not such a big fan of winter, i think i suffer from SAD or something. I may be going crazy but I sketched this far fetched idea to use the heat from the tube to heat a big indoor area with a lake and trees that we could go to in winter. If Dubai can build a ski slope then London should have one of these.
