Space-based datacenters simply won't work. That people are talking about them shows Musk is the greatest snake oil salesman the world has ever seen.
But it doesn't matter since in this scenario each chassis is powered exclusively by the respective panel. How hot does a black panel sitting in the midday sun get? That's your equilibrium temperature. As long as it's within the operational limit of the device there's no problem.
The reason earthbound DCs are difficult to cool is because of density. When you match up panels to devices and shelter in their shadow you no longer have anywhere near the same power density.
The reason people don't do it here is because it's too expensive.
For the record the equilibrium temperature in earth orbit is above freezing but below room temperature. Cooling won't be a problem at all unless you bring along a self contained power source. Heat distribution however might be - you will need an efficient yet lightweight construction to spread the heat generated in the chassis across the entire solar panel.
The reason we don't use them is because the other options are cheaper. But passive radiators on the ground are orders of magnitude cheaper than on space because they can use convection and conduction.
Yes, that is literally what I have been saying from the beginning. Are you sure you didn't misread my original comment?
> passive radiators on the ground are orders of magnitude cheaper than on space because they can use convection and conduction.
That statement is technically correct when comparing designs to radiate an equivalent amount of heat in the two environments.
However in context (ie solar powered computing in outer space in the vicinity of the earth) it is entirely missing the point that the problem is not a lack of surface area but rather efficient heat distribution across the already existing surface area. I have no idea how much that costs in materials and workmanship but when you're boosting things into orbit I don't think the material cost of a rudimentary heat spreader is likely to be of much concern. The weight certainly will be, but you can also get away with some incredibly flimsy designs when operating in zero g.
Everybody knows.
Musk is a snake oil salesman (that’s been clear since the self-driving car promises) but he also has made a lot of people a lot of money and that’s all anybody really cares about.
None of his companies have a traditionally reasonable valuation. Is there any reason to think that’s going to change soon?
A datacenter (earthbound or space) itself is a fantastical idea until a mix of events and inventions made it feasible to build them to sell compute.
It’s a engineering challenge not impossible.
After all, it's just an engineering challenge, not impossible.
Now if you have space based manufacturing or fuel production on the other hand ...
Its not a real argument it's just used because to most people the military is a big mysterious thing they don't understand which they think has an infinite budget for things.
