Fusion Idea – Could You With Lasers Move Heat With Network Precision? Not Heat With Lasers Just Move Heat

A quick idea.

I suspect you have to have 100% precision setting up conditions for fusion. Knowing in advance when fusion is going to take place.

Therefor I wonder if its possible to move heat in the right position with lasers. Not heat with lasers. Just move ?plasma or fuel in the exact right position.
