My brother is building his second truck. The first one took a week after he towed the engineless carcass into the yard. Dad now drives it to work. To get the engine and transmission into it he built a hoist out of wood. I used the Jimmy to push the carcass into position for the engine before I left on my trip. That's what can do people do. My brother can put any engine into any vehicle regardless of make, model or type. You add metal where it's needed. He rides to work on a regular bicycle he added a two stroke 80cc engine to.
That's the least of his talents. Now that he doesn't drink, there is no telling how much he will accomplish.
I said living on mars will be trivial compared to getting there. Naysayers point to hazards that are easily overcome by can do people. Martians will almost never work in space suits. There's no reason to. They will not work in a toxic environment. They will not work in a cramped environment. They will work in a lower gravity environment. So my brother wouldn't need my help to get an engine positioned. I have to laugh every time I look at the Mars One housing plan (well, and everybody else's as well.) Mars is a world. That is essentially unlimited space with unlimited building materials actually floating in the air. You can actually use pure iron and not worry about free oxygen rusting it, but paint it anyway. Or use steel. Or gold when they find some. Mars has lots of stuff free for the picking which they'll find by accident before they even start a serious search.
They will have industrial levels of energy that cost them nothing. The cost of energy on earth is due to lawyers, not economic reality.
Hell, life on mars will be much less oppressive than life on earth. This isn't some romantic notion. This is just plain fact. Mars has opportunity that no longer exists on earth. On earth, starting a business used to be trivial but isn't anymore. It used to be easy to find a market niche, but on earth somebody has already filled it.
Naysayers are just absurdly blind. Getting there is the only real problem. Even that will be less difficult (not easy) as some now claim. We just have to do it rather than talk about it.
A martian in a huge non toxic shirtsleeve environment (they have absolutely no reason not to be) may even forget they're on mars as they consider the millions of options regarding what to make or what service to provide others.
Martian dust isn't a hazard. That's wealth they don't have to mine. They just need a good vacuum hose and energy to process it. Knowledge they already have. Design will be both old and new.
Talk about land of opportunity!
