Make magazine 不是說的很清楚了麼：
"Low-power fusors produce a beautiful purple ion plasma “glow discharge” similar to plasma globes and neon signs. In high-power fusors, the inertia of the ion collisions squeezes hydrogen atoms tight enough to fuse, hence the term inertial confinement."

低能fusors ：就是一個熒光燈
高能fusors ：才是核聚變

到底是不是核聚變，用個Geiger counter測測有沒有中子放出就知道了.....
