In the 19th century, the world ran on steam. In the 21st century, little has changed. Every thermal power plant still relies on steam as a final stage.
The promise of abundant, clean energy powered by nuclear fusion is one big step closer thanks to a new experiment. The results are a historic scientific milestone, but energy production remains a ways off.
In January 2022, the JET fusion experiment produced more power over a longer period of time than any past attempt. Two physicists explain the engineering advancements that made the result possible.
The fastest things ever made by humans are spacecraft, and the fastest spacecraft reached 330,000 mph – only 0.05% the speed of light. But there are ways to go faster.
Scientists are working on ways to make lots of energy by converting matter into energy. The trick is keeping the process under control. One possibility is nuclear fusion – the Sun’s power source.
People long assumed all the elements we see now were created during the Big Bang. But on May 2, 1952, an astronomer reported spotting new elements coming from an old star and changed our origin story.
