What would happen if the inner grid rotated?

Post by Alec Fadness »

I read that alot of the particles that are pulled by the induced voltage collide pointlessly into the inner grid and do not fuse. What if the inner grid rotated at an increasing rpm great enough to move out of the way of the particles it pulls toward the inner grid? You could time pulses of high voltage such that particles are pulled quickly towards the tungsten wire, but the tungsten is given sufficient time and acceleration to move out of the way, increasing the particles that actually make it past the tungsten wire.

I would invite you to consider the ion velocities and calculate the RPM needed. You may find that the wires must move on the order of orbital speeds... Also consider where ions are formed, and how the act of moving the wires alters ion trajectories.

Not completely related to your question, but your post made me recall grid rotation experienced by my son 10 years ago. Reading through the thread, I'm not convinced we ever understood what happened.

Unsurprisingly I found the answer on fusor.net! (1,600,000 m / s) Source

Electric motors can spin pretty fast. Dyson has one that reaches 104,000 rpm! Source Imagine if you could pipe 30kv through a series of carbon brushes attached to the base of the tungsten wire grid as it spins at 104,000 rpm.
Also consider where ions are formed, and how the act of moving the wires alters ion trajectories.
I was considering this as well, I would like to find out!
