Spin Launch goes around in circles with Ka'u

that investment would be substantially higher here than elsewhere. 

But yet, the company wanted to build here.

I'm fairly sure the company wanted to build here for a very good reason; Hawaii Island is the closest place in the US to the equator, and being closer to the equator means you need to use less energy to launch a satellite due to the rotation of the Earth. That would reduce costs significantly. The other factor is you would be launching directly over the ocean which is always a good thing in case of a launch failure. As for needing a railroad or new highway, the observatories on Mauna Kea succeeded with either of those for decades and they also required brain power and existing infrastructure to work, so I don't see that as a relevant argument.

But the technical hurdles to spin something up to even a few thousand mph is far beyond what is feasible.

What is your opinion based on?
