Nuclear fusion is the process by which stars, including the Sun, generate their energy. In a fusion reaction, atomic nuclei ‘fuse’ together to form heavier nuclei. For this to happen, the nuclei need to have enough energy to overcome therepulsiveforce they experience because they are both p...
and more. these sunquakes are directly tied to the fusion happening in the core. and they're the only way that astronomers can get a glimpse below the surface. to make this work, astronomers take different models of the solar interior, changing how the fusion process unfolds, how energy...
The inside of future nuclear fusion energy reactors will be among the harshest environments ever produced on Earth. What's strong enough to protect the inside of a fusion reactor from plasma-produced heat fluxes akin to space shuttles reentering Earth's atmosphere? Zeke Unterberg and his team at...
To achieve fusion, you need to create special conditions to overcome this tendency. Here are the conditions that make fusion possible: High temperaturegives the hydrogen atoms enough energy to overcome the electrical repulsion between the protons. Fusion requires temperatures of about 100 million K...
The ITER is based on the tokamak concept, which uses a magnetic field within a torus-shaped vacuum vessel to confine a hot gas. The ITER's design provides for the inclusion of "blanket" modules in the walls of the vessel fo...

There are several types of fusion reactions. Most involve the isotopes of hydrogen called deuterium and tritium: Proton-proton chain - This sequence is the predominant fusion reaction scheme used by stars such as the sun. Two pairs of protons form to make two deuterium atoms. Each deuterium ato...
[TED Talk] 同步锤击如何能产生核聚变 | How synchronized hammer strikes could generate nuclear fusion 米歇尔·拉伯格 | Michel Laberge, 2014 00:00:13 哇,这儿很亮堂。 Wow, this is bright. 00:00:15 它肯定消耗很多能量。 It must use a lot of power. 00:00:18 你们都乘飞机来到这里 Well, ...
hinting that the dream of nuclear fusion power is inching closer to reality. We know that fusion works—it is the process that powers the Sun, providing heat and light to the Earth. But for decades it has proved difficult to make the transition from scientific laboratory experiments to sustain...
