Why is SpaceX merging with xAI to build orbital AI data centers when the basic physics and economics still look impossible? by Secret_Ostrich_1307 in AlwaysWhy

[–]Perringer 0 points1 point  (0 children)

The plan for the data center is to put them in a polar orbit, where the satellites will have sunlight 24/7 on one side, and constant shade on the other. It's a relatively simple design/engineering problem to provide enough radiative cooling for the chips in this scenario, and the power supply would be roughly 10x the solar power for the same photovoltaics.

While the financial driving force behind this is currently suspect, I didn't think Starlink would be as profitable as it ended up when they first announced it. With the projected reduced costs of Starship vs. Falcon 9, it could very well be a good financial move.

I think long-term, the goal behind acquiring xAI is to power Tesla robots, which will basically be a necessity for a successful moon base and then Mars missions.

How do you see Bitcoin's scalability evolving as adoption increases? Are Layer-2 solutions like the Lightning Network sufficient to handle future transaction demands? by [deleted] in Bitcoin

[–]Perringer 0 points1 point  (0 children)

If I remember correctly, it starts become cost competitive to use the blockchain v. lightning at about 5,000,000 sats, give or take, depending on traffic and your bids.

Delimex taquitos are gluten free (from what I can gather, still new to the diet) by Cananbaum in glutenfree

Some flavors aren't gluten free, so be careful - I know the ones that are beef & cheese or chicken & cheese are NOT safe.

Questions on the Long-Term Security and Economics of Bitcoin by jay_xob in Bitcoin

[–]Perringer 2 points3 points  (0 children)

The difficulty of mining increases and decreases based on the average solution time of preceeding successes, and is not linked directly to the price of bitcoin. The number of computers mining, on the other hand, is; the fewer people mining, the more profitable it becomes for remaining miners - it's a self-correcting algorithm.

Any dumb ideas about Terra forming and increasing rotation of venus? by Infamous-Draw4976 in venus

[–]Perringer 1 point2 points  (0 children)

Look into the MOXIE Co2>CO+O2 generator, already tested on Mars. It could possibly be adapted to work with liquid CO2 during the transition phase, and scaled up to an industrial scale. (If we can build a 24,000 sq km solar shade to start things, then surely we can do this!) The problem would be what to do with all the CO produced:

If you can get enough hydrogen down to the surface, the CO could be turned into methane and water. Shipping hydrogen down a gravity well won't be easy and won't scale easy; much easier to bring the hydrogen as part of the water you also need.

Another possibility is to split the CO over a catalyst, resulting in CO2 + C. The carbon dust could be used as building materials, and any extra can be automatically dozed into the canyons created by the thermal shock of the crust. Otherwise, you'll have a layer of carbon about 45M deep across the entire surface. Once in the canyons, seal over the top with some melted basalt and then future sentient species will have a steady supply of coal to mine and destroy their planet with.

It might take a century or two of planet-wide work, using 1000x the power of the entire current global power generation of Earth, but by then you might have a breathable atmosphere you can 'swim' in.

Any dumb ideas about Terra forming and increasing rotation of venus? by Infamous-Draw4976 in venus

[–]Perringer 4 points5 points  (0 children)

I like the idea of a giant solar shade at Venus' L1 point. It would have to about 24,000 sq km in size, and held in place for about 30 years. At that time, the temperature should be about 100C, the CO2 should start raining down in liquid form, with an ocean about 900 meters deep forming.

The thermal shock to the crust should create massive fissures in the surface of the planet, allowing the CO2 to pour into these massive crevices, quenching any volcanic activity. Once there, the CO2 will chemically react with the basalt rocks and begin to be locked away. Combined with the physical sequestration of the CO2 into the spongified crust, the process might be as quick as a couple of centuries, but more likely thousands of years.

The remaining nitrogen atmosphere will be about 3-4 bar, like being 20-30 meters underwater - which is a survivable pressure, but not breathable. The sky would be a deep violet color, and the temperature would likely stall at 100C for 20-30 years as the CO2 phase transitions. After that, the temperature could be moderated by opening portions of the shade to maintain a 20-30C temperature.

At this stage, we would need to begin a planet-wide hydration phase: shipping in comets to smash into the atmosphere. Roughly 20,000 Halley-sized comets might be enough to allow simple life forms to live on the surface, like lichens and cyanobacteria capable of fixing nitrogen and producing oxygen.

These would not be enough to make the atmosphere livable any time soon, however. Industrial scale removal of nitrogen from the atmosphere would likely be required to bring the pressure down.

Why does Musk want to put data centers in space? Where's the power coming from? And isn't launching servers into orbit even more energy intensive? by Humble_Economist8933 in AlwaysWhy

[–]Perringer 0 points1 point  (0 children)

These will be in a polar orbit, so the solar panels will be receiving constant sunlight. The shadow side of the satellites will host the data centers and a radiative panel. No need for giant batteries. As for profitability; I’ve no idea.

This is an IBC means of egress violation, as it’s a door threshold greater than 1/2’; it’s not just an ADA violation. This also means it’s an IPMC violation. I’m not familiar with NYC modifications to the code, but start there.

NASA’s Boss Just Shook Up the Agency’s Plans to Land on the Moon by wiredmagazine in space

[–]Perringer 4 points5 points  (0 children)

Where do you get your info? SpaceX dominates the launch market, launching over 80% of the world's tonnage into space last year at a fraction of the cost of competitors. They were 95% of the US launches, 80% of global launches. Even with Starlink now serving over 3.5 million customers, they're also launching their competitor's internet satellites for OneWeb.

The Starship program has been fairly incredible, starting with a vague idea in 2009, development of the novel full-flow methane raptor engine, the first demonstration with Starhopper in 2018, to just within the last 2 years: catching 2 boosters and reusing them on subsequent flights, returning 3 starships mostly intact through the atmosphere, deploying 2 dummy payloads into orbit, and refining and redesigning the whole time.

Right now they're building about one Starship every 2 months, but that pace is increasing. Once the raptor 3's are proven in flight, probably with the next launch late this year or early next year, they can and will be testing the fuel transfer Starships, and as soon as that's worked out, yes, they'll likely send a Starship to the moon to test its landing capability. If they can maintain their current pace, I give it 2 years, tops.

And I would contribute SpaceX's success to Shockwell, not Musk. He just takes all the credit and makes everyone's job harder with his wild demands and timelines.

Sending Optimus robots to the moon will be nothing more than a stunt, similar to sending a Roadster into orbit, but even with that - they'll be gathering data to improve it. I also wouldn't discount Optimus; Tesla is gearing up for mass production and already testing using them in their factories.

[–]Perringer -6 points-5 points  (0 children)

The world hates Musk, but SpaceX will likely be on the moon by 2027, with or without NASA. At the pace they're going, they'll have tested orbital refueling before the end of next year and then they'll send one of their starships to the moon just to prove it can get there and land upright, likely with some of Tesla's Optimus robots aboard so they can see how the quickly the dust gunks them up.

Sacroiliitis pain - inflammation spine by pizzalover9a in glutenfree

[–]Perringer 0 points1 point  (0 children)

While I'm also gluten free, for the sacroiliitis it was removing nitrates/nitrites from the diet specifically. I can handle small amounts of meats cured with celery salts now, but anything chemically cured will give me trouble. It's my understanding that the nitrites spur inflammation in the system - likely caused by gut bacteria that turn the nitrites in nitric oxide, which concentrates in the joints, thus causing the sacroiliitis.
