The guy who’s funding $45 million a month for the candidate that wants to end EVs and pump more oil? That Elon?

Do Tesla’s EVs offset SpaceX rockets?
- willy_k 2y ago
  They don’t even offset themselves, but SpaceX rockets would likely be a key part in deploying solar shades if necessary
  - ainoobler 2y ago
    How does that solve the problem of fossil fuel emissions?
    - willy_k 2y ago
      It can decrease the solar exposure of the earth and potentially decrease temperature, doesn’t address fossil fuel pollution but it does mitigate the impacts of fossil fuel CO2.

        What are the material requirements for this proposal?
        willy_k 2y ago
        I am not well versed but my impression is it’s essentially a bunch of tin foil and the main impediment are geopolitical reasons and cost to orbit, which SpaceX has been and continues to improve.

        Okay, so having gone down this path I can tell you it is impossible. To reduce the output of the sun by 2% at L1 would require 20 MM tons of metal. In order to launch that much tonnage we would have needed to start launching mass 500 years ago. And that assumes no loss of material over time, which would mean even more launches. It is not feasible.

        Thank you for adding some numbers regarding the feasibility of launching the required materials into space. Do you have any thoughts/numbers about how "mining/construction" in-situ in space might affect those outcomes? E.g. Might we soon be able to "recycle" old in-orbit objects (trash/old_sats) into a slowly growing space mirror? Or several smaller ones over (richer/more_affected) areas?

        So not really. Space mining is a very attractive idea but just not really feasible at the moment. I wrote a paper on attempting to capture the asteroid 433 Eros (a very attractive asteroid due to it's composition of rare metals [Data from the Near Earth Asteroid Rendezvous spacecraft collected on Eros in December 1998 suggests that it could contain 20 billion tonnes of aluminum and similar amounts of metals that are rare on Earth, such as gold and platinum.]) and found that in order to knock it into an orbit around the moon we'd need something on the order of 1 THOUSAND or 10 THOUSAND (I could be off by even another magnitude, the numbers are fuzzy after all this time) tsar bomba grade weapons to effectively knock it out of the current orbit and back into one around the moon. Why the moon? Because throwing a planet killer sized object at the Earth just didn't seem reasonable. I situ mining might make this more feasible, but that has all of its own complications. None of which I would feel confident in saying are feasible. https://en.m.wikipedia.org/wiki/433_Eros https://en.m.wikipedia.org/wiki/433_Eros https://en.m.wikipedia.org/wiki/Tsar_Bomba https://en.m.wikipedia.org/wiki/Tsar_Bomba

        Wikipedia says: > A more recent design has been proposed by Olivia Borgue and Andreas M. Hein in 2022, proposing a distributed sunshade with a mass on the order of 100,000 tons, composed of ultra-thin polymeric films and SiO2 nanotubes.[7] The author estimated that launching such mass would require 399 yearly launches of a vehicle such as SpaceX Starship for 10 years.[7] That seems very feasible to me.

Do you have any idea how much CO2 is released in a single rocket launch? LOL

Hard to believe he is doing this. It's absolutely nonsensical, I think Elon really is having mental health issues. Either that, or everything he has said about being "pro human" was a lie. Which isn't hard to believe either.
- zo1 2y ago
  I'm sure he has his motivations that he has internally justified and made sense of. Saying he has mental health issues because he supports Donald Trump because somehow Trump is pro oil and that'll massively hurt the EV industry sounds like a huge stretch, be honest. Even a casual reading of Elon a lot of us squint and make the conclusion that he supports Trump because he thinks it's what your country needs, heck like a lot of us do, EV industry be damned. The left is clearly destructive with open borders and a lack of crime policing, even if it's noble, that it's very likely that everyone including Elon is choosing Trump as a correction to the arguably insane and self-destructive policies of the left.
  - pnut 2y ago
    US republicans and democrats have largely the same policies except for social wedge issues. My bet is that Elon knows Trump is pliable if you come with an open checkbook, so there's real opportunity to advance your business interests if he's president.
    - bamboozled 2y ago
      I think this is true also, it's calculated to some degree, but shit can go really bad with this approach too, it's playing with fire. Ask Jack Ma about dealing with autocrats or those who "strongly admire" autocrats, as Trump has said repeatedly. He admires, Xi, he admires Putin, he admires Kim Jung Un. At some point he might decide some of your wealth, might just be some of his wealth. It's wild, really wild, I can't believe this is America we're talking about.
  - bamboozled 2y ago
    Why on earth do you think America needs Trump? I'm honestly interested in your opinion. Why do you say that? Even if as the other commenter said, it's about advancing business interests through bribes, it's a slippery, dangerous slope. Trump is the kind of person who might end up deciding his Son in Law should be running your company...based on his track record of appointing morons to high places. I really still can't imagine what is going through his mind. Trump is a deplorable person even if you think he is funny or entertaining.
