Final answer:
No, ion propulsion cannot work in the atmosphere to lift people.
Step-by-step explanation:
No, ion propulsion cannot work in the atmosphere to lift people. Ion propulsion engines are designed to operate in the vacuum of space, where there is no air resistance. Ion drives use electric fields to accelerate charged particles, typically xenon ions, to generate thrust. In the atmosphere, air resistance would significantly hinder the efficiency and effectiveness of an ion propulsion system. Therefore, alternative propulsion methods like jet engines or rockets are used for aircraft and spacecraft that operate within the Earth's atmosphere.
