Highlighting a study from Massachusetts Institute of Technology researchers, the entity explained last month that the “geoengineering” project seeks to reflect a portion of solar radiation back into space. The group said that a device, which covers an area the size of Brazil, would likely pose “no risk” of disrupting the planet’s ecosystems because of its deployment in space rather than in the atmosphere.
“Geoengineering might be our final and only option,” Carlo Ratti, an MIT researcher and architect, said of the project. “Yet, most geoengineering proposals are earth-bound, which poses tremendous risks to our living ecosystem. Space-based solutions would be safer — for instance, if we deflect 1.8 percent of incident solar radiation before it hits our planet, we could fully reverse today’s global warming.”
The bubbles, made of a thin plastic material, would be manufactured in space and positioned at the L1 Lagrangian Point, where the gravitational pulls between the Earth and the sun cancel out.
According to an MIT press release, “This proposal addresses many questions: How to engineer the best material for the bubbles to withstand outer space conditions? How to fabricate and deploy these bubbles in space? How to make the shield fully reversible? What are the potential long-term effects on Earth’s ecosystem?” Read Full Article >
