The real use of these orbits is increasing the number of geosynchronous satellite slots by 3X. They could also provide better comsat coverage at high latitudes.
The ref to climate change was probably put in by some NASA PR twinkie.
The basic science is not “agenda driven”; it is really useful science for comm apps.
BTW, I had the honor of meeting Dr. Forward and contributing to one of his projects in a minor way. He had a contract from USAF to check out inertialess drives and other far-out space propulsion ideas.
He found that almost all of the novel ideas were BS or violated the laws of physics. However, he found two winners: tethers and antimatter drives. Either of those could revolutionize space travel.
Yeah I learned about the nanotube thethers from his fiction. Very interesting and novel idea for climbing into and out of gravity wells.
