Gravity does not travel faster than light because it is already there. It is a shape in space-time--at least I think that is what Einstein said. Now, if you want to argue that the current body of theory is a mess, I'll agree with you. The two main theories don't agree on the crucial matter of time, ...

Please remember that Dr. B had envisioned that the final coils would be either square or pentagonal in plan-form (not cross section, plan-form)with rounded corners. I think this will tend to reduce the overall stresses in the magnet because the coil and virtual coils forces will be better balanced....

4 cm wall thickness? that seems excessive. BTW I was hoping Cu was good enough for the outer wall. It's conductivity would give some help with cooling. And later it might be good to make the first wall such that it had "fingers" extending into the H2O to improve cooling. The main limitation in reac...

That's a matter of how you finish the stainless. I figure most of the inner tubing should be 316L or something similar. Aluminum coated Mylar does just about the best job at dealing with infrared. I suppose we could use it for lining in the insulation jackets. They used Mylar for a Echo 1, I think, ...

The inner loop should be more like a 10 or 20 degC delta T.

By this I gather you intend to pre-heat the water. It makes good sense.

Okay, good! Now I have something I can chew on. I'll be back w/ some pictures in a few days. The way I see it, we have a lot more to go on that Leslie Groves had. It's gonna be rough, but it ain't like I have anything better to do at the moment.

Flow sheet with respect to what? Project management? Control hierarchy? I'm already working on processor design, A/D and D/A converters. code etc. Er, a flowsheet of the cooling system for the electromagnets. You've been working on the instrumentation, I assumed you'd have been working on flowsheet...

I'm thinking of pressure headers with every coil fed individually. With DP transducers, P transducers, inlet and outlet temps, and valves to see that the flows are even and sufficient. A power plant is going to need a lot of control. Fortunately the control on the second or third one will be cheape...

So I can see, but as far as I can tell, and this may be simply be because of my faith in Doctor Bussard. He said the physics is done, so it's done. What I think is left boils down to two hairy engineering problems. First is the electromagnets, and how do we capture extremely irate He nucleii so as t...

:D I am one of those rare old farts that has yet to see an MRI! I've seen 'em on TV so I don't know if I am seeing all of one. Either way, we are talking about a monstrous great difference in scale, along with a huge difference in temperature differences and pressures in what amounts to a a single v...

Vibration is going to be a problem as well. I think it will prove impossible to have all six of the magnets connected together in series in the coolant loop. That would require high velocity flow and the head on the discharge side of the coolant pumps would skyrocket. Looking at the constraints impo...

Not a bad take on it for a "dummy". Thank you very kindly, Doctor Carlson. Just remember that compared to nearly everyone else on this forum I am an innumerate troll. There are times around here when I may as well be in Japan because I can't even read the street signs. Just 2 comments: It is surpri...

I don't see how the electrons can slow down the nuclei. The nuclei are headed for the center of charge at a high velocity thus they have a lot of momentum. Given that an electron masses about 1/1836 that of a proton, you're basically firing a cannonball through a cloud of butterflies. Of course, if ...

I am writing this because I am a real dummy when it comes to particle and quantum physics and I am hoping someone will read it and tell me if and where I have gotten the basic ideas wrong. I have a fairly solid grip on how vacuum tubes work so when I look at the BFR, I tend to think of it as a soupe...

I just found a skecth on your blog, MSimon. Here's another possibility for you. First is the core surrounded by LHe. Next is a vacuum jacket. After than is a LN2 jacket followed by another vacuum jacket. Between this vacuum jacket and the first water jacket, add a jacket of ultra high molecular weig...
