Fusion

 It's not feasible or even possible to achieve sustained net positive nuclear fusion without knowledge of static electric fields.

Enough said?  Almost.

Both toroidal and stellarator designs have issues with confining plasma and energy loss.  At least that much is understood.

There exists a (relatively) simple way to skirt or workaround the issue.  It's to stop pretending the plasma doesn't exist within a static electric field.

It should be modeled as a plasma within the highest strength static electric field which can be induced.  The only secret ingredient after that is a twist.

Literally.

One or more twisting static electric fields under magnetic confinement are a decent way to increase compression or density outside of utilizing a gravitational field.

Otherwise it's all types or forms of waves to the rescue.

That implies a backwards reactor design.

If you get my drift.
