Although there are nine known isotopes of helium (2He) (standard atomic weight: 4.002602(2)), only helium-3 ( He ) and helium-4 ( He ) are stable. All radioisotopes are short-lived, the longest-lived being He with a half-life of 806.7 milliseconds. The least stable is He , with a half-life of 7.6×10 s, although it is possible that He has an even shorter half-life. In the Earth's atmosphere, there is one He atom for every million He atoms. However, helium is unusua

Background and HistoryFission vs Fusion ReactionsEquations of Fission and FusionWhy Is The Moon So Important?How Much Helium-3 Is on The Moon?What Makes Fusion on The Sun Different?Readings and ReferencesEveryone learns about Helium in school. It is the second element in the periodic table having 2 protons, 2 neutrons and 2 electrons - having an atomic mass of 4. But another form of Helium has been in the news lately and it is called Helium-3. Helium-3, also written as 3He, is a light isotope of helium having 2 protons but only one neutron and an atomic mass of 3.

ESA - Helium-3 mining on the lunar surface

The idea of harvesting a clean and efficient form of energy from the Moon has stimulated science fiction and fact in recent decades. Unlike Earth, which is protected by its magnetic field, the Moon has been bombarded with large quantities of Helium-3 by the solar wind. It is thought that this isotope could provide safer nuclear energy in a fusion reactor, since it is not radioactive and would ...

Helium-3 and Nuclear FusionMining Helium-3 on The MoonA Flower in The Darkness?To provide a little background -- and without getting deeply into the science -- all nuclear power plants use a nuclear reaction to produce heat. This is used to turn water into steam that then drives a turbine to produce electricity. Current nuclear power plants have nuclear fission reactors in which uranium nuclei are split part. This releases energy, but also radioactivity and spent nuclear fuel that is reprocessed into uranium, plutonium an在explainingthefuture上查看更多信息

Against this, helium-3 (a non-radioactive isotope of the gas used to inflate balloons) offers remarkable advantages: its fusion with deuterium is more efficient than deuterium-tritium and does not release neutrons but protons, which can be easily contained thanks to their positive charge. In addition, it is possible to capture its energy to ...
