Another story.

The neighbors, live stock and wildlife will endure constant sonic booms for almost an hour. Longer for the centrifuge to wind down.
Actually, it is 10,000 Gs. There is no way a standard rocket would survive that stress.
How do they balance the spinning mechanism at those
high RPMs once the rocket is released.
Just don’t see this as workable.
I just noticed this was published in Popular Mechanics. Fuggittaboutit!
Shiff’s head looks like it experienced 1000 g’s.
What happens when the rocket barfs all over itself during the spin-up?
I think a better idea is an orbiting spacecraft recycling plant. Get a system that concentrates the power of the Sun to melt down parts of disassembled spacecraft. Some things are probably reusable. Use robots as much as possible. They don’t need as much support equipment to function, and don’t waste time looking at the internet or arguing about politics.
Like a fun game of “catch” - with Lawn Darts!
Holy cow. At least he was returned to flight status.
Yeah...that was bad. I’m thinking broken facial bones.
By my calculations, a centrifuge the size of a football field moving at 5000mph would produce 5,576Gs.
There’s something in the description that can’t be right. Is there any construction material that could withstand that? It would have 233 rotations per minute. Four rotations per second. Something just can’t be translated right here.
If you could aim this it would be one hell of a way to lob large tungsten balls halfway around the world at a speed that would produce substantial kinetic damage
We fired payloads with electronics into suborbital ballistic trajectories into space, in the 1960s with extreme cannon. There were a lot of Gs involved.
The Lockeed SR-71 Blackbird flew around 2,200 mph and air friction heating of surfaces was a huge problem. How, exactly, is this rocket going to spin around in circles for about an hour until its speed eventually exceeds 5,000 miles per hour and not melt or fall apart from the heat?
They might be able to release the counterbalance at the same instant that the rocket is released. That would mean two exit ports, one for the rocket and one for the counterbalance. I don't know how they would handle the tremendous momentum of the counterbalance. Maybe use a water-containing cylinder that would break up when it hit the ground?
The ‘Plumbbob’ nuclear launched manhole cover?
Interesting, thanks. Maybe it's not a serious problem.
It spins in a near-vacuum.
A bowling ball in a washing machine comes to mind
