It is but you can’t anchor one end of the cable at 250 miles because it will have to be moving compared to the ground at 28.000km/h (17.000+ mph) which means that you’d have a cable whipping around the earth at that speed. I mean the destruction would be monumental haha.

What you do is you anchor the cable at a geosynchronous orbit so it will be still compared to the earths surface at 35.000km away.

That’s a damn long cable lol.
