Without an economy or currency to speak of, it'll likely start out like a technocratic communist society with democracy. Once an industry is established and exports start, a currency will emerge and capitalism will take root.

As per the outer space treaty, there won't be any Earth nations drawing borders, but colonists might disregard the treaty once they are self sufficient and establish nations without Earth governments to enforce the treaty.

Yaghi invented metal-organic frameworks more than 20 years ago, combining metals like magnesium or aluminum with organic molecules in a tinker-toy arrangement to create rigid, porous structures ideal for storing gases and liquids. Since then, more than 20,000 different MOFs have been created by researchers worldwide. Some hold chemicals such as hydrogen or methane: the chemical company BASF is testing one of Yaghi's MOFs in natural gas-fueled trucks, since MOF-filled tanks hold three times the methane that can be pumped under pressure into an empty tank.

Other MOFs are able to capture carbon dioxide from flue gases, catalyze the reaction of adsorbed chemicals or separate petrochemicals in processing plants.
In 2014, Yaghi and his UC Berkeley team synthesized a MOF - a combination of zirconium metal and adipic acid - that binds water vapor, and he suggested to Evelyn Wang, a mechanical engineer at MIT, that they join forces to turn the MOF into a water-collecting system.

The system Wang and her students designed consisted of more than two pounds of dust-sized MOF crystals compressed between a solar absorber and a condenser plate, placed inside a chamber open to the air. As ambient air diffuses through the porous MOF, water molecules preferentially attach to the interior surfaces. X-ray diffraction studies have shown that the water vapor molecules often gather in groups of eight to form cubes.

Sunlight entering through a window heats up the MOF and drives the bound water toward the condenser, which is at the temperature of the outside air. The vapor condenses as liquid water and drips into a collector.

"This work offers a new way to harvest water from air that does not require high relative humidity conditions and is much more energy efficient than other existing technologies," Wang said.

This proof of concept harvester leaves much room for improvement, Yaghi said. The current MOF can absorb only 20 percent of its weight in water, but other MOF materials could possibly absorb 40 percent or more. The material can also be tweaked to be more effective at higher or lower humidity levels.

"It's not just that we made a passive device that sits there collecting water; we have now laid both the experimental and theoretical foundations so that we can screen other MOFs, thousands of which could be made, to find even better materials," he said. "There is a lot of potential for scaling up the amount of water that is being harvested. It is just a matter of further engineering now."

Yaghi and his team are at work improving their MOFs, while Wang continues to improve the harvesting system to produce more water.

"To have water running all the time, you could design a system that absorbs the humidity during the night and evolves it during the day," he said. "Or design the solar collector to allow for this at a much faster rate, where more air is pushed in. We wanted to demonstrate that if you are cut off somewhere in the desert, you could survive because of this device. A person needs about a Coke can of water per day. That is something one could collect in less than an hour with this system."

I can do this with a tarp

pushes the tides. it's been hypothesized by some that life on earth may not exist without it.

>>8856813
Would the lakes and oceans be completely still without the moon?

What about water that's underground?

>>8856839
Wind and currents would still move the earth's waters around, but the moon has a big effect as well so its hard to know exactly what would change.

Also the moon is like our secret service guy taking asteroids for us and shit.

Sahara plays an important part in the ecosystem. Terraforming it would do more harm than good.

If you had used Google you'd know we can and have done things like this. it's just that nobody cares.

Read "The Misbehaviour of Markets" by Mandelbrot.

That seems interesting. Thanks!

Have you read it?

Very interesting.
I am also interested in applying these concepts with parallel infinities.

I dunno, anyone have an energy cannon to plug into this?

An off road electric vehicle? That's kind of self defeating, no?

Wow... go Chevrolet! It does look cool.

>I don't get how come some people can just work for hours on end without procrastinating or burning out.

1) He got paid good money for every second he was working on it
2) He didn't do it in one go. He wrote it as he felt it come to him

That said, I appreciate his work but I would consider him more of a genius if he could take the relevant bits of his theory that prove ABC and turned them into elementary number theory arguments. My biggest problem with him is that I doubt we need all that fucking bullshit symbol soup to describe ABC. And sure, maybe his larger theory has more to it than just proving ABC but the least he can do is condense the proof of ABC for us little brainlets over here.
