Helium-3

Betty's helium-filled aerostat, three metres across, is capable of carrying loads of a little over half a kilo.

Helium 3 is not hazardous or even chemically reactive, and it is not the only material that can be used for neutron detection.

However, there is a very attractive reaction between deuterium and a light isotope of helium known as helium-3.

The Daedalus spacecraft weighed around 50, 000 tonnes, almost all of which would have been a very rare Helium isotope called Helium-3.

Moon dust contains hydrogen, which could be used to power rockets, as well as helium-3, a potential fuel for fusion reactors.

Canisters of the harvested helium-3 are then sent to Earth to be used to generate fusion energy.

Fire a high-speed proton at a Boron target and the two fuse together to form three helium nuclei and a lot of energy.

Helium-3: very rare on the surface of the Earth, very common in space.

The ingredient is helium 3, an unusual form of the element that is formed when tritium, an ingredient of hydrogen bombs, decays.

Unlike helium-3 we know the moon has large amounts of hydrogen, as ice, and a significant fraction of it will be deuterium.

You guessed it; the best helium-3 supply in the solar system is from the "Gas Mines" of Uranus.

Helium 3 is used to detect neutrons, the subatomic particles that sustain the chain reaction in a bomb or a reactor.

The deuteron can fuse with another proton to make a helium 3 nucleus.

There are rich mineral resources on moon, among them helium-3 is the most promising future energy source for the mankind.

Core 3: Before the Wright Brothers invented the airplane, anyone wanting to fly anywhere was required to eat 200 pounds of helium.

It also bodes ill for the prospect of fusion using helium-3, a rare helium isotope that is missing a neutron.

Trapped inside the fullerenes is a concentration of helium 3 that is many times greater than what is found in the Earth's atmosphere.
