With climate change on everyone’s agenda, researchers include new approaches based on strict deadlines to restore our planet on a positive course, with geo-engineering at the center of these efforts. They cover systems that range from building massive walls on the seabed to technical projects aimed at slowing down glacial melting.
Now a team of researchers has released a study that evaluates the development of various solar energy projects. Their work was motivated by the fact that programs designed to inject aerosols into the atmosphere can be environmentally risky and very expensive.
The concept, called stratospheric aerosol injection (SAI), includes the delivery of sulphates in the lower stratosphere. In addition to cost and feasibility, the team also looked at whether projects like this should remain confidential and if released to the public, which channels for information sharing should be used.
Dr. Gernot Wagner, from Harvard University’s John A. Paulson University of Technology and co-author on the paper, discussed how sensitive the subject of solar engineering is:
“While we do not make any assessment of desirable by SAI, we show that a hypothetical installer that begins with 1
5 year from now on, both very uncertain and ambitious, would be technically possible strictly from a technical perspective.
It would also be remarkably cheap, on average about $ 2 to 2.5 billion per year in the first 15 years . “
The scope of the vision presented to SAIL (the Loftier version by SAI)
-> Development costs would include $ 2 billion for the aircraft and an additional $ 350 million for any necessary engine modifi ments.
-> An average of approximately 4000 flights in the first year, which gradually increases to 60,000 at the end of a 15-year period. -> A doubling of (1) traction force and (2) wing area and (3) the number of engines (from four to two) would be needed for to make the aircraft ready for the job.
-> An expected fleet of eight to begin, which will increase to 100 at the end of a 15-year period.
With all indications, research has shown that SAI is a profitable solution, but only if sound planning and radical restructuring of current models are performed. And in a refreshing way, the team also sees the development of SAI as positive and cautious about forming geopolitical conspiracy theories about inappropriate use in the future:
“Given the potential benefits of halving average projected increases in radiation fluctuation from a certain date forward talks these figures for the “incredible economy” for geoengineering. Dozens of countries can finance such a program, and the necessary technology is not very exotic, “said Dr. Wagner.
Details of the study are shown in a paper titled “Stratospheric Aerosol Injection Tactics and Expenses in the First 15 Years of Deployment,” published November 22, in the Environmental Research Letters Journal.
