Elon does have some pretty exciting ideas and the money to back most of them up, you never know it could happen. Can't help thinking I might have been born a tad early for this one.

"...can't see it happening..."

I'd wager some people of the past said the same thing of Edison and Ford...but that's speculation...

For those that enjoy lockdown, breathing from a bottle, cold and geology - then short term Mars will be fine.
The difficulties of living on a hostile planet that you have to bring or make everything you need to live, including oxygen, make global warming problem pale into insignificance.

Forgive me but I'm a bit confused over that comment.

The Earthlings could simply make there own electricity from solar and wind. (Mars has plenty of sun and wind for power too)

Gas and fuel shouldn't be needed at all, ok maybe a little oil for lubrication.

To me going off grid on Earth doesn't mean you can't visit supermarkets.


Of course on Mars people would have to be completely self sufficient, even make their own oxygen, but to compare attempting to live on a barren planet to people going off the electricity grid here on earth does seem to be pushing it a bit, at least to my mind, starting a new civilisation from scratch is a whole new ball game isn't it or am I missing something?
