@TheDaleJackson Then why did he sign that letter about Tim Walz as a Staff Sergeant? Getting paid as an E-6 is not even remotely the same as earning those stripes, as you well know. He has provided no satisfactory explanation for that.

Phil says this is stupid because radiators are a "solved problem" but then stops short of extrapolating what that means.
The radiator surface area they specify is about the right size for the math to check out. You can make pretty much any physics "work" if you scale the right values on paper. The feasibility isn't about physics, its about economics.
For a moderately sized 100MW "data center" you'd need a fleet of close to 700 satellites to match its earthly alternative. That's an ISS's worth (the most expensive single structure ever built by humanity) of radiators, 700 times over, for a single "data center".
To put that into perspective that's about 73,000 m² or roughly 14 football fields worth of surface area
The costs to build such a fleet is insane compared to the the earthly alternatives we have yet to exploit and it assumes a lot of things that might not continue to hold true - like wattage per op staying constant.
It’s like someone looking at room-sized computers in the 50s and extrapolating that we are going to have a land crisis and starts imagining large floating sea platforms to host our computing future
Here’s what Jerry is missing:
Space isn’t just a vacuum, it’s a vacuum with a sink temperature of 3°K, so if you want to reproduce it on earth you don’t just pull a vacuum, you pull a vacuums in a container with 3°K walls.
And when you do that it becomes ~10x more efficient.
@jayforalabama We need a transparency law in AL… the Secretary of State needs to post all details about any PAC or other group that spends any money in AL. Location, tax status, principals in the organization, funding sources, etc.
It’s always great to see investment dollars being pumped into the great state of Alabama.
I had a great time down south earlier today meeting folks, hearing what’s happening on the ground, and seeing firsthand the kind of growth that keeps our communities strong.
Alabama is open for business because our people know how to get the job done.
That’s the kind of Alabama I’ll fight for every day.
Make sure to vote on June 16.
Alabama is the arsenal of America.
We shouldn’t be sending $40 million a week to the Taliban when we have important infrastructure that is needed here in Alabama.
As your next U.S. Senator, I will fight to get investment dollars for our infrastructure, our trade schools, our jobs, our workforce, and preparing our people for the jobs we have now and the good-paying jobs of tomorrow.
Putting Alabama First is the highest priority of a US Senator from our state.
Alabama is the arsenal of the United States of America. I'll fight to make sure we maintain that arsenal.
I can't do it without your help.
I’m asking for your most important thing you can give, your vote on June 16th.
Today I was joined by over a dozen veterans.
The voters of Alabama deserve the truth, and I have been willing to answer the questions because this Senate seat belongs to them.
But the first time my opponent gets asked real questions about things that he himself has said in the past, he hides behind Washington, D.C. lawyers and threatens to sue anybody who keeps asking.
Then, when his own words and his own record don’t match up, he runs to his crypto buddies and lets them spend another million and a half dollars lying about me.
I will always stand with those who have sacrificed for our country, but I will not stand by while career politicians run on their coattails for political gain.
Alabama deserves the truth, not D.C. lawyers, crypto money, and more lies from the swamp.
Physics PSA:
I’ve just realized that most people think that because radiative cooling isn’t efficient on earth it isn’t efficient in space.
Radiative cooling is ~10x more efficient in space because there is no warm air to radiate heat TO the radiator.
