The "energy question" was not verifyably addressed. With good reson. To extract water from martian glaciars is possible. Maximum recovery rate is 98%, The remaining 2% will have to come from earth. Every onion, every french fry and every hamburger will have to be imported from the earth. I woulden't want to live in a place like this. The little "blue planet" is the only home we will ever have, regardless what Elon says. Truly, it's the only home we will ever have. To construct "new homes" for humanity is an exercise in futility, regardless what Elon says, there is not enough money in the world to make it possible. And there is also not enough conviction for us earthlings to leave our "unice blue planet". As it is truly unike, regardless what Elon Musk "envisions " in his "disturbed" sleep.
