Heinlein does not provide a description of how this propulsion system works; however, he compares it to the method still in use today:

Then some unknown race had chanced upon the dreamers and decided to "help them out."
'Improving man by bringing him close to Nature, while they combine the sensations of coasting with the interest of seeing the country well...'
Um, how about that pension for the humans who serve as the models for robot behavior?
'...used as surrogates in intense dependency cases.'
