Chips are definitely a thing in the UK. Like French fries but usually chunkier: https://en.wikipedia.org/wiki/Fish_and_chips
If you are lucky, you get triple-fried chips. Which are just as good/bad as they sound.
I.e. extremely good and not at all bad.
You would have to 1) keep turning it toward the sun and b) reduce time in earth's shadow, which means a polar orbit?
This is really, really exciting. The moment this spark ignites, it will herald a new reality for industrialization of space, and I for one cannot wait to see it succeed. One of the things I truly believe will elevate our species is space industrialization. If, in 20 years or so, we send a fleet of space furnaces to 16 Psyche [1], there is a very real possibility that we will be able to move a lot of Earths heavy indu…
Research has gone this direction several times. Every time it did, ground factories discover some way to improve their quality so that space manufacturing became irrelevant again. That's not to say it will happen again. But it's not a certain thing.
I'm only YouTube-level informed on how silicon manufacturing works, but something that is, perhaps intentionally, not made clear to someone unfamiliar with the field is that this is not manufacturing chips in space. This is to grow the crystals only, the very first step in silicon chip manufacturing. This is how you get the ingot, then you slice it to get the wafers upon which the chips are built. The reason you woul…

4000 times purer seems a questionable claim to me. 4000 times purer then what? Current Earthbound state of the art? A guy in shed with a vacuum pump and a heater? On what axis: crystal defects or contamination? High vacuums aren't at all impossible on Earth and silicon boules are already single crystals. What exactly about their process permits such a huge quality improvement?
The best silicon single crystals still contain impurities at the 1E-11 level. This project is about doing crystal growing in low gravity (the ultra-high purity is only achieved due to the growth process). The vacuum of space is a lot worse than what can be achieved in the lab, especially in low orbits.

I'm not saying it's practical, but it's pretty cool.

Which doesn't mean it's not another example of the same phenomenon. Many companies do things that are not, and will never be, profitable (in the traditional sense), because they have ulterior motives.
False. The objective a company is to make profit, anything else is a side quest and is less relevant. There isn’t an “ulterior” motive here. The motive is clear: profit. We just can’t pinpoint the exact pathway to it in terms of details.
> a heat shield named Pridwen after the legendary shield of King Arthur will be deployed to protect the spacecraft from the intense temperatures it will experience as it re-enters the Earth's atmosphere. Why bring back the entire spacecraft and not just the finished product? I'm also curious how they handle cooling the silicon, since dissipating heat in space is kind of difficult.
Plus, they can study the oven after the process which is likely to be helpful if the entire experiment poops the bed.

Which is called Fish and Chips in Canada, even though it's served with fries.

In the Netherlands we have two words for fries and you know if someone is from the north or the south based on their use: Patat, north en Friet, south, particularly in the South people are sensitive to using the wrong, northern word. (And chips are just crisps here.)
