This podcast discusses colloid thrusters, a type of engine that is similar to ion engines, but is considered its own class.
27:38 - 30:14 (02:36)
Summary
This podcast discusses colloid thrusters, a type of engine that is similar to ion engines, but is considered its own class. While ion engines have an ionization chamber and inject propellant into that chamber, colloid thrusters require an external cathode to produce electrons that neutralize the beam.

The heat generated by rocket engines needs to be taken into account, especially for smaller satellites.
30:14 - 31:12 (00:57)
Summary
The heat generated by rocket engines needs to be taken into account, especially for smaller satellites. While chemical and plasma engines are extremely hot, colloid engines are cooler and utilize colloidal particles to generate thrust.
