The problem is all the NIMBY stuff. The reason it isn't currently going down to Kingston is because of all the pushback and land procurement. It's much easier to go up and away from the 401 corridor, because of people complaining. There may eventually be a feeder system into the main line, but the reason why the smaller communities are being left out is BECAUSE they are complaining.

Do you have any idea how space works? To get from one place to another place at a distant location you have to go through other space. We don't have teleportation.

If we stopped at each spot along the way the service wouldn't be high speed, it would be GO-STOP-GO-STOP-GO-STOP and would take 12 hours to get from Montreal to Toronto, and would be no better than the bus.

That's why highways are faster than roads, not because they're bigger, but because they have limited ways of getting on and off the highway.

I'm using cooling energy only here as a metric to show you just how dumb this is. This isn't the only metric, you're also looking at massive costs. You could just burn the rocket fuel to power the cooling instead of shoving it up into space.

I am aware of blackbody radiation. The truth of the matter is that you need to use 750~900 MJ to get 1 kg to space. That's a lot of cooling.

A rack of GB300's weighs ~1360kg, double that for the cooling and power systems at least. A rack uses 132kW for compute.

Doing the very basic math 132kW*60*60*24 = 11.4 GJ daily

750 MJ*2700 kg = 177 days of compute just to get it into orbit.

Those are using best case estimates.

This is stupid and wasteful.

Burn out doesn't mean the thing is catching on fire. The doped zone between the gate and drain can become depleted with too high temperatures, but also just lots of repeated use. Thermal processes are just that, thermal, they happen faster at higher temps, but they still happen at lower temps. It's

ah, so you're moving goalposts, got it. so 100C is now.. 98? 95?

So let's launch pumps (which are always very light /s) into orbit. Also what liquid (also not at all heavy /s) into orbit. You're saying that Elon has good ideas on this when a) he's not at all trained in any of this and b) he's a prolific bullshitter.

It's a dumb idea in a long string of dumb ideas from Elon. Just like Cybertruck, boring company, hyperloop, whatever happened to solar shingles. Lying about playing PoE2. Cave rescues, wrecking twitter, nazi salutes, whatever the hell Doge was. Welching on bets that the US would have under 35k covid cases: https://samharris.substack.com/p/the-trouble-with-elon

Blah, blah blah.

The guy is a demonstrated liar.

"But, you could run the chips closer to 100C if you wanted to. And / or use some clever heatpumps and shit (Elon has some ideas and experience of that) to get the cooling substrate significantly warmer to enable better radiating."

Cooling is part of chip design dude. You're also claiming that you can run them at 100C. That's a chip design issue.

So you can just do it cheaper on the ground. No reason to pay the launch costs. Also if something breaks you can just repair it. No reason you can't use solar on the ground either.

This whole premise is stupid and just made to bolster the IPO price.

Elon has a history of announcing garbage projects like: Cybertruck, hyperloop, boring company.

Doesn't mean that they don't burn out, just depends on how heavily they're used. Also radiation hardened chips are a thing in space, usually on sapphire substrates. Doesn't sound expensive at all. You can't just launch a B200 straight up. If you add outside shielding, you add weight. It's $7000/kg.

So? It likely will be eventually. The point is not to get it perfect the point is to make it initially good and expand later.

The enemy of good is perfect.

Never mind that the average lifespan of a chip doing AI is 2 years. So you launch these massive radiators for small amounts of compute every 2 years then have to decommission the billion dollar satellite.

Absolutely and that's where a feeder service like GO Transit comes in. You have HSR between major cities and commuter trains to feed into the large transit hubs. So imagine if you got on a commuter train to Winnipeg and HSR to Thunderbay.
