The [[motion picture]] adaptation, ''[[Atlas Shrugged, Part 1]],'' gave a more detailed suggestion of how an electrostatic motor might work. Specifically, it employed a variation on the Casimir Effect, which classically is an attraction between two metal plates brought close together. In fact, an Israeli scientist actually proposed building a "quantum propulsion engine" that employs the Casimir Effect.<ref name=casimir>Feigel A, "[http://arxiv.org/abs/0912.1031 A magneto-electric quantum wheel]," ''Quantum Physics'', 5 December 2009.Cited in "[http://www.technologyreview.com/blog/arxiv/24499/ A Blueprint for a Quantum Propulsion Machine]," ''Physics ArXiv Blog,'' 9 December 2009.

The [[motion picture]] adaptation, ''[[Atlas Shrugged, Part 1]],'' gave a more detailed suggestion of how an electrostatic motor might work. Specifically, it employed a variation on the Casimir Effect, which classically is an attraction between two metal conducting plates brought close together in a ''quantum vacuum.'' (The term "atmospheric vacuum" in the film script is not accurate.)
