  • You’re right, we’ve got to get rid of fossil fuel. As one example, the article talks about how energy storage has reduced the need for gas peaker plants. In California in April the power required from those plants was half what it’s been in April the prior three years.

    Still plenty of progress that needs to be made, but what’s notable is that it’s now cheaper for a business to turn to green energy and storage to solve a problem. There’s not an incentive to build new polluting tech. So while the impact of climate change is going to get worse (because those emissions and warming are already baked in) the business argument for fossil fuel is no longer viable.



  • With respect, I think you’re projecting a discussion with a different person onto this article.

    You’re right, the climate is going to get worse before it gets better. You’re right, the impacts of climate change will disproportionately affect poor and underdeveloped areas. We can’t make that go away with positive thinking, and it’s not enough for humans as a species to survive, we need to focus on reducing suffering while we’re turning the ship.

    What I took away from this article is that the market forces for cheap renewable power and the means to store it are now stronger than the forces for CO2 emitting power. And those forces are moving faster than predicted. That’s good, and it’s ok to talk about something good when it’s true!

    People who have been paying attention and care about others have good reason to be wary about the narrative “oh, everything is going to be fine” because that’s what industry and politicians have been saying for a long time instead of taking needed action.

    We’re at a point where most people recognize climate change is real, and they can see it’s effects. We’re also at a point where many people don’t have hope for the situation. It’s dangerous to tell people “shit’s fucked and there’s nothing you can do about it” because they might believe you and do nothing.














  • Meaning no disrespect, it’s clear from your response you’re not familiar with space history. And that was my point - a lot of people are jumping in here and making negative comments just because of the Musk association without knowing or caring about the reality.

    The space shuttle (the U.S.’ s previous manned “reusable” vehicle) was retired in 2011, and the Crew Dragon was ready in about 2020. NASA was not forced to use Soyuz because of a delay in the Crew Dragon, it was because the Space Shuttle had two previous fatal disasters, was way more expensive than planned, and would be even more expensive to keep running. I didn’t know this until looking at the wikipedia just now, but early safety estimates put the chance of catastrophic failure and death of the crew between 1 in 100 to as low as 1 in 100,000. After those two disasters they re-evaluated and put the risk as high as 1 in 9.

    NASA was willing to take a chance on other contracts for commercial vehicles because it had no other options. It awarded contracts both to SpaceX and ULA. The first is doing dozens of uncrewed launches per year and has flown 12 crewed missions. The other is doing like 3 launches per year, has yet to fly Starliner with a crew, and costs more per launch.

    The space shuttle vehicle itself was re-usable. The “external tank” was discarded and not re-used. The solid rocket boosters would fall into the ocean, and then would have to be recovered, examined and refurbished. Those tanks/boosters represented a huge portion of the cost. While the space shuttle was slightly more re-usable, other rocket launches would be single use. What SpaceX did that no one else had before was a controlled vertical landing of the booster. In other words, it landed under power and standing up. That’s very difficult, and a game changer since it skipped the recovery step, and they didn’t require the time and cost of examination / refurbishment the way the space shuttle components did.

    What is it you want to say about Artemis?
