Helium-3 is a very rare gas with the potential to fuel clean nuclear fusion power plants. However, one of the problems is that the nearest supply of helium-3 is on the Moon. This video by Christopher Barnatt discusses the nuclear physics, space exploration and global politics that may be involved in mining the Moon for helium-3. More information can be found in the “Helium-3 Power Fact File” on ExplainingTheFuture.com All visuals were produced for this video using LightWave and After Effects.
