EarthSweat

Several political and academic figureheads have put forth the notion that the overall atmospheric temperature is steadily rising due to human activity, and that the Earth will be shortly uninhabitable if Government does not institute Draconian conservation measures and embark on outlandish public works projects. In this regard, I am proposing that we cool the Earth by releasing hydrogen gas produced from the electrolysis of water into the upper stratosphere. Because hydrogen is less dense than air, it will leave the earth via atmospheric escape, carrying any heat it has with it.

This all works best if the hydrogen has as much thermal energy as possible when it dissipates into the void. If the gas is simply released at the surface and allowed to rise naturally in the atmosphere, it will exit the atmosphere at whatever the ambient temperature is up there. In addition, it could be oxidized and be trapped as water. Therefore, this method is only made practical by the use of a 60-mile-high, insulated pipe that empties above the atmosphere, the construction of which is outside the scope of this idea. The hydrogen is heated in the base of the pipe and then pumped upwards at incredible pressure to maximize the amount of gas that is dispersed.
