First postulated by Jules Verne in his novel From the Earth to the Moon, the idea of space cannons is not new. Many engineers have toyed with the concept, but nobody has came up with an actual project that may work. Hunter’s idea is simple: Build a cannon near the equator, submerged in the ocean, hooked to a floating rig. At the cannon’s bottom there is a combustion chamber, which uses natural gas to heat hydrogen up to 2,600ºF, increasing the pressure 500%. When released, the gas will launch a capsule with half a ton of material into space, at a swooshing 13,000mph.
