Aleksandar Guzijan: *

Helium-3 is a non -[[radioactive]] and light isotope of [[Helium]]. It has two [[proton]]s but only one [[neutron]] in contrast to two [[proton]]s in ordinary [[Helium]]. Helium-3 is hard to come by on [[Earth]] and sought after to use in [[fusion]]. Relatively abundant Helium-3 is thought to exist on the [[Moon]] and the [[gas giant]]s in our solar system.

Helium-3 is used in [[cryogenics]] to achieve temperatures as low as a few

thousands of a [[Kelvin]].

Famous novel by Arthur C. Clarke. Set in the 22nd Century it describes the construction of a geostationary tower or orbital "beanstalk" a giant structure rising from the ground to the geostationary or Clarke Orbit at the height of 36000 km approx. Such a building would permit cheap access to space without the need for rocket ships. Materials exceeding the tensile strenght of diamond would be needed thought.
