As envisioned by Frankel and Frank Davidson, a former MIT researcher and early member of the first formal English Channel Tunnel study group, sections of neutrally buoyant tunnel submerged 150 to 300 feet beneath the surface of the Atlantic, then anchored to the seafloor–thereby avoiding the high pressures of the deep ocean. Then air would be pumped out, creating a vacuum, and alternating magnetic pulses would propel a magnetically levitated train capable of speeds up to 4,000 mph across the pond in an hour.

Abstract:
The Very High Speed Transit or 'VHST' concept was put forward some years ago in response to the search for a pollution-free transport method that could operate at speeds competitive with aircraft. The general principles are relatively straightforward: Electromagnetically levitated and propelled cars in an evacuated tunnel. The VHST's 'tubecraft' ride on, and are driven by, electromagnetic (EM) waves much as a surfboard rides the ocean's waves. The EM waves are generated by pulsed or by oscillating currents in electrical conductors that form the 'roadbed' structure in the evacuated 'tubeway.' Opposing magnetic fields in the vehicle are generated by means of a loop of superconducting cable carrying on the order of a million amperes of current. The system is highly conservative of energy. Economic, environmental and technical aspects are briefly considered.

Zorgon - you are a hive of fascinating information.

So you consider the LA Times and Rand Corporation "pop science"
