It sounds like science fiction, but Christopher Ottersbach’s concept airship may one day become a reality. The aerodynamic ship seats 2 to 4 people and could potentially travel for two weeks filled with helium. No infrastructure is necessary. Additional thrust and steering is provided by the crew’s pedal-powered propulsion.

No more Goodyear blimps. We may have reached peak helium levels, as this inert gas is endangered.

According to Scientific Blogging, helium is not readily renewable and is made through from uranium and thorium decaying over billions of years:

Lee Sobotka, professor of chemistry and physics at Washington University in St. Louis, says it is being depleted so rapidly in the world’s largest reserve, outside of Amarillo, Tex., that supplies are expected to be gone there within the next eight years.
