Out of curiosity, I decided that I would build a Tesla Turbine and possibly use it for some interesting contraption. Except, when I was reading about it, I always heard that it can achieve high RPM, but has low torque. I was just wondering if someone would be able to explain the concept of torque, what it does/what it's used for, and what not. I've tried reading up about it, but I'm still having trouble grasping exactly what it's for. Thanks, Peter.
