You can’t build a space elevator without an zero-g manufacturing complex in space because earths gravity wreaks havoc on producing the thousands of miles long uninterrupted molecular graphene nanotubes for the elevator cables and you can’t have a zero-g manufacturing complex without a facility on the moon to lower costs

Not an option. iOS doesn’t have the all of the options that I want. Such a emulators and accessing the file structure via a file manager.

I’m also just recently bought a new iOS device a 2022 iPhone se. I bought it to replace my iPod touch and oh boy the differences between iOS 9 and iOS 16 make it look like a completely different OS some things I can’t figure no matter how many times I try to google it mostly because I can’t get a straight answer.

Like Twitter won’t play videos when I’m signed in through the safari browser I also can’t seem to share pictures from webpages straight to my google drive from safari it just won’t show the thumbnail preview before I press save to drive

So your saying that you want Crome to use up 90% of your system memory while windows defender runs in the background ? No thanks that was total hell everything slowed to a craw. granted that was on a entry level laptop meant for web browsing and light use and had only 4GB of ram but it is supposed to just be a damn web browser

One of the problems I have with Crome on android is that it gives itself root level access to your phone but you as a user aren’t naturally given that level of access it’s because of that I’m not allowed to backup my bookmarks directly on my phone in an organized way without them being a jumbled mess.

I know I can back them up to google and download a zip file of by bookmarks in an organized structure but then there goes my browsing privacy if I didn’t want my privacy tracked.

I know I could’ve used another browser but Crome being the default browser on android means that you’ll no doubt end up having a lot of bookmarks saved because of convenience before you realize your mistake and having to sign into google to backup again

That’s not how orbital dynamics works. If an object in orbit suffers a head on collision it will rob the object of its orbital momentum and all of the corresponding debris will fall into a lower orbit were it will burn up. To shift and object to a higher orbit you have to add energy to the object. collisions always tend to rob energy from moving objects

They got to the karman line and landed using a single stage rocket so they definitely have some talent The several engineers that designed the NASA DC-X delta clipper were hired by blue origin to design the new shepherd so it would be safe to say they have the expertise to pull it off

Only if the sun is within 160 million miles from earth (earth to the sun is 93 million miles and mars closest approach to earth is 70 million miles) of corse putting a sun at that distance would destabilize all of the orbits of the gas giants and cause Jupiter’s orbit to to become so eccentric that it would gravitationally either kick the inner planets out of our star system or send them falling into the sun

You could eliminate Medicare/Medicade military healthcare Known as tricare food stamps and the other bureaucratic social services and merge it into the social security administration and use every citizens social security number to deliver the money directly into there checking accounts therefore bypassing the states and all of their individual bureaucratic bloat. this could save many tens of billions in bureaucratic costs you could call it basic universal services.

Aside from collectibles and science, the point of asteroid mining isn't to bring stuff back to Earth. It is to replace the high cost of launching stuff from Earth.

Let's say the Starship rocket works as intended and can fly for $20 million a launch. It takes about five tanker flights plus the cargo launch to get ~120 tons to the Moon's neighborhood. So $120 million for 120 tons is $1 million per ton. If you can mine usable products from asteroids for less than this, you come out ahead.

Metallic asteroids contain about 15-50 parts per million of the "Platinum group metals" (the ones below iron, cobalt, and nickel on the Periodic Table). Parts per million is the same as grams per ton, so 15-50 grams per ton. Average PGM price is around $50/gram, so market value is $750-2500/ton.

They are alloyed with the three base metals as ~90% iron, 1% cobalt, and 9% nickel (the proportions vary by sample). So first, you have to extract the PGMs from a chunk of iron alloy, and second a little added carbon turns the iron alloy into a decent steel alloy. There are other asteroid types (the carbonaceous ones) with carbon, so that's not hard.

Now your ton of metallic asteroid is worth $1 million for structural steel in space, because that's the launch cost you avoid for not launching structural parts from Earth. The value as structural metal is worth way way more than the small amount of precious metals in it.

You can try to separate out the PGMs before leaving the asteroid, or afterwards so you can use both the iron alloy and the PGMs, but I highly doubt you can process it in space for the $750-2500/ton market value. For comparison, the price of hot-rolled ordinary steel on Earth is $775/ton right now.

Future Windows on ARM could be as bad as android smartphones are today with locked down boot-loaders and unsupported driver chipsets. God help you if your windows ARM chip is a Qualcomm one. You’ll never be able to update your pc after 3 years or install an an alternate OS on it. ARM is also owned only by a single company the x86 instruction set is owned by two companies ( intel and amd ) intel and amd would rather develop an open source RISC-V architecture then pay constant licensing fees to ARM

The only problem is that many cable companies also own the internet infrastructure in Florida 4 years ago my choices for cable/internet were century link with 5mb dsl. bright-house. Comcast. And time Warner which was not bad considering what other people only have access to. Today now it’s just time Warner and Comcast because time Warner gobbled up fucking bright house and century link isn’t worth it because of the damn speed. So now I’m down from 4 service providers down to two until century link upgrades to fiber

Well depending on the damage you aren’t going to be able to repair them on site step 3 and 6 being very important quote from article

Production. The typical manufacturing process of an LPT consists of the following steps:

  1. Engineering and design: LPT design is complex, balancing the costs of raw materials (copper, steel, and cooling oil), electrical losses, manufacturing labor hours, plant capability constraints, and shipping constraints.

  2. Core building: The core is the most critical component of an LPT, which requires a highly-trained and skilled workforce and cold-rolled, grain-oriented (CRGO) laminated electrical steel.

  3. Windings production and assembly of the core and windings: Windings are predominantly copper and have an insulating material.

  4. Drying operations: Excess moisture must be removed from the core and windings because moisture can degrade the dielectric strength of the insulation.

  5. Tank production: A tank must be completed before the winding and core assembly finish the drying phase so that the core and windings do not start to reabsorb moisture.

  6. Final assembly of the LPT: The final assembly must be done in a clean environment; even a tiny amount of dust or moisture can deteriorate the performance of an LPT.

  7. Testing: Testing is performed to ensure the accuracy of voltage ratios, verify power ratings, and determine electrical impedances.

It’s actually only 2 to 5 years because only a few companies actually build them and they have to be ordered years in advance they can weigh hundreds of tons and can only be hauled by specialized rail cars and tractor trailers

Nuclear thermal electrolysis is over 85 percent efficient because your using that raw thermal heat to push the H20 molecules up the energy gradient then all you need is a very small amount of electrical current to break down the molecules into hydrogen and oxygen
