Airborne wind turbine prototype 2012

Airborne wind turbine prototype 2012

(1:30) First public video of a 35-foot-wide airborne wind turbine by Altaeros Energies. The scale prototype harnessed strong winds up to 350 feet high to produce over twice the power of traditional wind turbines. Winds at higher heights are much stronger and more consistent than on the ground.

Helium is the second most abundant element in the observable universe, being present at about 24% of the total elemental mass

You are both correct. Second most abundant in the universe (24%), very rare in terrestrial atmosphere (0.00052%). The real problem with helium is keeping all of the technicians from speaking with high voices.
