Ion Thruster
Ion Thruster
We are in need of help designing the ion thruster model on the Van de Graff. We have built the second design that is supposed to be more robust and consistent, but we cannot get it to spin like the video. Is there anyone we can communicate with to get more help in the design? Thank you
