Where Does Jeff Bezos Foresee Putting Space Colonists? Inside O'Neill Cylinders (geekwire.com)

Elon Musk of SpaceX wants to settle humans on Mars. Some talk about taking the Moon Village route. But Jeff Bezos has a different kind of off-Earth home in mind when he talks about having millions of people living and working in space. His long-range vision focuses on a decades-old concept for huge artificial habitats that are best known today as O'Neill cylinders. From a report on GeekWire (edited and condensed): The concept was laid out in 1976 in a classic book by physicist Gerard O'Neill, titled "The High Frontier." The idea is to create cylinder-shaped structures in outer space, and give them enough of a spin that residents on the inner surface of the cylinder could live their lives in Earth-style gravity. The habitat's interior would be illuminated either by reflected sunlight or sunlike artificial light. Bezos referred to his long-term goal of having millions of people living and working in space, as well as his enabling goal of creating the 'heavy lifting infrastructure' to make that happen. In Bezos' view, dramatically reducing the cost of access to space is a key step toward those goals. "Then we get to see Gerard O'Neill's ideas start to come to life, and many of the other ideas from science fiction," Bezos said. "The dreamers come first. It's always the science-fiction guys: They think of everything first, and then the builders come along and they make it happen. But it takes time." For Musk, the prime driver behind settling people on Mars is to provide a backup plan for humanity in the event of a planetwide catastrophe -- an asteroid strike, for example, or environmental ruin, or a species-killing pandemic. Bezos sees a different imperative at work: humanity's growing need for energy. "We need to go into space if we want to continue growing civilization," he explained. "If you take baseline energy usage on Earth and compound it at just 3 percent per year for less than 500 years, you have to cover the entire surface of the Earth in solar cells. That's just not going to happen. [...] I predict that in the next few hundred years, all heavy industry will move off planet. It will be just way more convenient to do it in space, where you have better access to resources, better access to 24/7 solar power," he said last weekend. "Solar power on Earth is not that great, because the planet shades us half the time. In space, you get solar power all the time. So there'll be a lot of advantages to doing heavy manufacturing there, and Earth will end up zoned residential and light industry. [...] We want to go to space to save the Earth. I don't like the 'Plan B' idea that we want to go to space so we have a backup planet. ... We have sent probes to every planet in this solar system, and believe me, this is the best planet. There is no doubt. This is the one that you want to protect."

    There were some engineering failures in those designs.

    It was usually assumed that the contained atmosphere would become thinner approaching the axis - and that doesn't happen. On a sphere, the rising air currents are formed due to the density difference between upper and lower air. Unfortunately with a rotating cylinder anything NOT in contact with the rim doesn't rotate - hence no force to rise.. Yes, there is a boundary layer right at the rim - but once above that, nope. The simulated force decreases the closer to the axis of rotation you get... thus "clouds" would not form. To get a cloud, the rising air column has to expand... but in a cylinder there is no place to expand to.

    The other problem was that they used 1/3 of the cylinder to reflect lighting through - also doesn't work, as it makes the core axis too hot.

    What would happen (without the heat) is that the core around the axis would become a single cloud, and little to no air circulation.

    Same thing happens if you spin a raw egg. It doesn't spin because the liquid center can't - the turbulance at the axis stops it, and that propagates out to the rim.

      That would probably help solve a bunch of other problems too, actually. If it was necessary to have more than one section in-rotation, so that counter-rotating forces allow the structure to otherwise maintain stationkeeping assuming that the center core sticks out the ends of the structure, that not-rotating core would be the place for the critical infrastructure to be housed. It would also allow for a transit-point between counter-rotating sections where the amount of risk for things like simple gasket failure would be small, and would let stores that don't need gravity or an approximation thereof to be stored such that less forces are imparted on the outer cylinders of the rotating sections. It would also serve as a good microgravity laboratory that's easily accessed from compartments that are better for the occupants, and if there's risk of radiation storms, the inhabitants could retreat to the core for the duration so that both outer and inner layers are protecting them.

      Transiting from the rotating section to the core could be accomplished by use of basically a moving sidewalk and a ladder/clamp system. The moving sidewalk speeds the occupant to match the ladder on the stationary core, then one simply grabs on and now in microgravity, pulls one's self along, tying on to safety points as one goes. Alternately they could operate some kind of motorized car or lift, but that probably would only be necessary for moving larger goods.

      That central core could also act as the point where "daylight" emits from, and as you point out, could be used to stir the air in the environment.

To move longitudinally, you get a running start, and you will move in a diagonal path. Most practical O'Neill cylinder designs have the major roads laid out as helixes to simplify movement.

    The problem with using space-based industry to send power to Earth has a very simple problem: heat. If we replaced all the of energy industries with space based solar cells we'd no longer locally generate power. But our devices would still inefficiently convert that power to work with waste heat. This makes the energy budget for the Earth even more fun to calculate.

    Today "insolation adds 1366 W/m2 to the Earth. A lot of that trapped by the Atmosphere, rocks, water in the oceans and a non-trivial part in plants. Putting more solar cells on the surface of the Earth doesn't really change the heat budget. Trapping more of the light with greenhouse gases does, pushing the balance up a bit. Blocking out Sunlight with soot pushes it down a bit.

    Focusing more light on the Earth does change the budget and quickly. Just to meet today's needs we would have to provide between 525 and 600 quadrillion Btu (source). Right now we do that with the sunlight energy either already stored up here or current sunlight falling onto the planet from space. (And some geothermal left over from radioactive material and the heat trapped from smashing a bunch of stuff together to make the planet.)

    Right now, since we are supposed to be in an Ice age, this might be an advantage. Without the constant pumping of greenhouse gases to keep the temperature up this in-fall of more energy and waste heat could be used to keep the surface comfortable.

    But what happens when we go past that point? Nobody wants to turn off their TV, air conditioning or cellphones for a few days to keep the heat budget in check. Just like today nobody wants to stop using the cheapest oil, coal or plasticizer no matter the cancer, coughing or smog filled skies.
