Guest essay by Eric Worrall
Italian architect Paolo Venturella has proposed a gigantic megastructure to prevent global warming, though building it may present a few practical difficulties.
Our planet is going through the irreversible process of global warming, and even if various strategies have been planned to solve the problem, none of them provided a solution.
This is causing natural disasters all over the planet. The temperature all around the planet is increasing making the ice in the pole melt.
Only a “global strategy” can be adopted.
To cool down the temperature a huge greenhouse is placed in between the sun and us.
This works according the same principle of the “solar tower”. Thanks to the accumulation of heat in the glazed structure, air flows naturally from hot to cold generating rapid and strong flows. These flows bring hot air far from the Earth cooling down the temperature of the whole globe.
The air flows restore better climate conditions and moreover generate renewable energies by wind turbines placed inside the structures.
Its worth visiting Paolo’s website just to see the gargantuan scale of what he is proposing – a vast horizontal building touching the Earth’s equator, whose size appears to dwarf the diameter of the planet.
As I said, there are a few practical difficulties, such as smelting all that construction steel using wind power, finding a way to get a chunk of the Earth’s crust to support trillions of tons of building, handling the centripetal stresses caused by the Earth’s rotation, preventing the building from “seesawing” on its mount, and probably a host of other civic engineering issues.
Paolo’s diagram of what appears to be hot air venting into deep space also raises some obvious concerns about the long term impact of his proposal, even if such a structure could be built.
However, lets hope Paolo qualifies for his Cyclotron Road funding – in my opinion the megastructure proposal makes at least as much sense as some of the other projects being funded by the US government, and Paolo’s idea has a sort of cosmic grandeur.
