Legit came to this sub to ask how to downgrade to 7 . This is funny timing lol . <| sep |> I think you can but those at ica as well . Really good for being frozen pizza . Or well , fresh but cold . <| sep |> Oh I tweaked , u right . I meant Ancient Elf is worse than a rushed Beastcall Aria . <| sep |> Perhaps it isn ' t a cure for smog , the creator never claimed this single unit would . but it is a step closer than we were before this was installed . I disagree . If the technology isn ' t really working , or if its energy requirements cause more smog than it cleans , or if the cost is too high , than we aren ' t a step closer and all that has happened is the people who made it get richer . The problem with smog removal has always been energy and cost . If the cost is too high people won ' t use it . If the energy cost is too high than it makes more smog than it removes . MAYBE you could use solar , wind , tidal , etc and power smog removers only when you ' ve got surplus from that . Sort of air cleaning as a form of energy storage , except instead of storing the energy you ' re cleaning up the mess left by fossil fuels . But even that ' s going to take real cleanup , and that means serious juice . You ' ve got to suck a crapton of air through your filters to even make a dint in the smog problem . Hundreds of thousands of cubic kilometers of air , and that means big , powerful , fans . Then there ' s the removal problem . Just sucking the air through does nothing , you ' ve also got to have a process to remove the particles . Ionizing the air works , though less efficiently than you ' d like to think . And then there ' s the ozone problem . You create O 3 when you ionize the air , it ' s unavoidable . So then you need to add more energy spending gear to break that O 3 back down or you ' re polluting with your antipollution device . I don ' t know what their patented process is for not producing ozon why did they leave off the terminal e ? Is this a weird legal trick , they claim it produces no ozon and since ozon doesn ' t exist and the actual pollutant is ozone they ' re free and clear ? but any real process will involve energy . Raising awareness is great , raising awareness by claiming to have solved the problem with something that doesn ' t actually work is not so great .
