    Wissenschaftler schlagen „Stormwall“ vor, eine hypothetische aktive Verteidigung im Weltraum gegen katastrophale Sonnenstürme, die mit der aktuellen Technologie erreichbar ist

      I think this was already posted here a little bit ago, but it’s a neat idea lol.

      It actually sounds realistically priced, but the minor note about needing significant advances in solar storm prediction in order to make it work is a _much_ more pressing issue. Spending a few billion dollars to protect ourselves is all well and good, but spending the same to realise you pulled the trigger an hour late is a disaster – not only would it be a waste of money but people will naturally assume the problem is solved and take no other preventive measures.

      So with this idea you have to re-send a significant amount of material into space for each CME you want to slow down. So only really a thing you would activate for carrrington-event CME’s.
      Not too bad I guess.
      If you want to permanently shield a planet, a few starships worth of material would probably enough so construct a permanent magnetic generator that permanently shields the planet more. Something with a few MW of power generated trough solar panels that then drives a superconducting magnet was in discussion to give mars its magnetic field back so that terraforming it results in something more permanent

      It will get really weird when a terrorist group eventually gets access to something that could blow up the sun if they wanted to. Where is Kurt Vonnegut when we need him!

      The real hurdle to this project isn’t technology, but political will. Convincing governments around the world to spend a massive amount of money to save vastly more money and lives in the near future? Sounds like a good deal. But then, how’s that argument working out for climate change mitigation?

      The only way to build momentum for something like „Stormwall“ would be for an actual catastrophic CME to hit Earth. We’ll just have to hope it’s both catastrophic enough to spur substantive action but not so catastrophic that millions die.

      Life before death, strength before weakness, journey before destination.

      Nice to see a proposal to influence nature and Earth that has been around longer than those scientists. The implications of the wall on biodiversity is not researched for all we know humanity may have started with a burst that modified and sped up evolution. So before calming the storm use them brains to look beyond the scope of the project.
