The way I learned the basics of welding, machining, electronics, and vacuum engineering is via a project in high school: building a demo fusion reactor. Without the input of deutrium, the device is really a plasma generating machine. Obviously, it does not produce extra energy.
I designed the machine from scratch and calculated the properties of the plasma to conclude that it is no more dangerous than a microwave. However, it was until I built a working prototype and measured it with a geiger counter that my teachers and classmates are convinced that the reactor is completely safe. Overall, it was a fun demonstration of an intriguing electromagnetic phenomenon.
