Advances in the potential energy source may not be about electricity, at least at first.
Nuclear fusion is the process that powers active or main-sequence stars and other high-magnitude stars, where large amounts of energy are released. A nuclear fusion process that produces atomic nuclei lighter than iron-56 or nickel-62 will generally release energy.
In May 2023, the United States Department of Energy (DOE) announced a $46 million grant for eight companies across seven states to advance fusion power plant designs and research, aiming to establish the U.S. as a leader in clean fusion energy. The funding from the Milestone-Based Fusion Development Program supports the goal to demonstrate ...
[168] [169] [170] Notably, in June 2021, General Fusion announced it would accept the UK government's offer to host the world's first substantial public-private partnership fusion demonstration plant, at Culham Centre for Fusion Energy. [171] The plant will be constructed from 2022 to 2025 and is intended to lead the way for commercial pilot ...
Temperatures hotter than the center of the sun, the highest-energy lasers in the world, magnets the size of a basketball court — and the promise of virtually unlimited energy on Earth.
According to Kritcher, if the experiment is replicated, and nuclear fusion energy is eventually made viable for commercial production, a bathtub's worth of salt water and two laptop batteries ...
Fusion processes are very sensitive to temperature so the star can produce more energy to retain hydrostatic equilibrium, at the cost of burning through successive nuclear fuels ever more rapidly. Fusion produces less energy per unit mass as the fuel nuclei get heavier, and the core of the star contracts and heats up when switching from one ...
There are other unanswered questions about the practicality of using fusion to generate energy all over the country, including whether existing power plants can be retrofitted for that purpose, or ...
