I propose to you the following conjecture: Is it possible to directly convert solar energy in a mechanical form?

Could the large linear theta pinch be the solution for thermonuclear energy?

Is it possible to test the sonofusion with the deuterium-tritium reaction?

Inertial fusion tries to make the fusion of deuterium and tritium by implosion of a target irradiated with lasers. This implosion is obtained in an indirect way by the expansion under the impact of lasers of an ablative material that surrounds the mixture D-T. Three important parameters control inertial fusion.

Has lithium been already tested with D-T fuel in target fusion?

A small addition of lithium in target could perhaps boost the beginning of inertial fusion.
