Fusion is the sun’s energy source. It is essentially inexhaustible, and that’s a major reason for the interest in developing fusion technology to generate power. In the sun, light nuclei such as hydrogen, under extreme gravitational pressure and excited by temperatures of 10 million to 20 million°C, collide with such force that they are fused into heavier ones. The fusion generates heat, maintaining the high temperature and keeping the reaction going.

The market is generally healthy and steadily growing, and margins are up for large specialty contractors. Further, advances in design tools and owner demand for collaboration are giving subcontractors a seat at the table early on in projects.
