Electric Solar Wind Sail is interesting concept. https://www.electric-sailing.fi/technology.html
The sail is made from 50-100 long (e.g., 20 km), thin (e.g., 25 microns) conducting tethers (wires) that rotate to keep the shape.
Electron gun keeps the wires in a 20 kV positive potential. The electric field of the wires extends 20m into the surrounding solar wind plasma.
It can be used only for braking (de-orbiting satellites) inside planetary magnetosphere.
