How to Build a Resistojet?

  1. Jun 2, 2011 #1
    Can I build a resistojet? How?
    I am in tenth grade and I want to make it for Science Fair.
    A resistojet takes a non-reactive fluid, heats it up using a filament and electricity. The fluid is heated and shot out of a nozzle. Can something like this be built? Can you guys give me some advice? The thrust is small but it is high efficiency, usually for spacecraft propulsion.

    Resistojets have been around since the 1950s.
