Which is why you use solar-powered mirrors for energy. Do take a look at the SPS designs, basically using solar sails to reflect the energy to a generator which can transmit the power to a smelting plant, or keep it focused for smelting, or transmit the energy to Earth as a low density microwave beam. The mining equipment is a bootstrap operation. The first loads of iron smelted from the satellite are used to build the next generation of mining equipment. There is an initial startup cost a "priming of the pump"., but as much as possible you use space based resources.

Energy is _outrageously_ available once the first solar power mirror based plants are working. NASA's last estimates guessed about 20 years to provide return-on-investment for the first few built. They don't have to be in close proximity to the smelting, they can in theory beam the energy as microwaves across empty space.

There are many reasons. The start-up costs are high, and the risks of regulatory issues or unexpected technical issues are high. It's why it's been the province of governments, and business deeply allied with governments.

I said _nothing_ about it being easy, but this is exactly the sort of project NASA and their consultants look at regularly. SpaceX would be in a good position to start it with space-based solar power, if Elon nMusk had not gotten fixated on reaching Mars.

"Decarbonize the rocket fuel".... What rocket fuel? Use solar sails to guide asteroids, slowly to a feasible orbit. Use solar sails as well to mine Saturn's rings for ice, and solar power mirrors to electrolyze the ice for hydrogen and oxygen rocket fuel. Where is there carbon in the fuel?

Bans on Sharia law exist in numerous US states, though it's not a federal ban. Concerns about the treatment of women in communities which apply Sharia law locally are one of the reasons that many nations, including the UK and Poland, have struggled with the behavior of the recent floods of Muslim refugees. The Wikipedia article "Bans on Sharia Law" even cites Germany's attempts to limit communities self-administering Sharia law.

The last thing any of us should want is for OpenAI to take over from Google.

I really don't understand this decision that Google should be broken up as though its 'monopoly' in search isn't entirely based on skill and talent. But if we *are* going to force companies to break up into components, can we make sure new monoliths aren't just created as a result?

Comment Re:Vet your dependencies. (Score 1) 51

"Do your research". On what? The Golang, Rust, NodeJS, JPackage, CPAN, Pypi, or other source repo hosted tools with dependencies scattered everywhere? One may as well rely on the label "Made in America", it's impossible _by design_ to see past the "layer of abstraction" and verify the whole code stack. This is one of the primary goals of "object oriented" software, to conceal anything but the snippet you are tasked to work on.

There is plenty of iron, and untouched rare earths, shown in spectrographic analysis of asteroids. Mine them in space, pay some attention to tailings and exudates, and mining should be safe for thousands or even millions of years depending on the amount needed. Use the results directly in space for space construction, mine Saturn's rings for ice for life support and reaction mass, and we could have a real space industry.
