    Is material abundance actually possible?: Technologists

    Fifty-eight cents per cubic meter In 2015, Sorek desalination plant opened south of Tel Aviv. 624,000 cubic meters of drinking water per day from the Mediterranean, at 58 cents per cubic meter — half the cost of a decade earlier....

    Venezuela only has a window of opportunity of maybe 5 to 10 years to make money off its oil. Solar and battery technology is catching up fast, and if the country waits too long, its oil resources will no longer be worth much....

    What cool new technologies are you seeing emerge? How do we know we can trust them?

    Curious about all, but I'd especially love to see non-AI versions, like: New batteries for solar: storing heat in big piles of dirt A while back Tommy mentioned cowfart backpacks Maybe it's something old for you, but we're not in your field so we don't know about it yet Even...

    When it comes "the global warming debate," there are often third ways that are ignored. Often the framing is global warming and climate deniers or something like that.

    but it seems like there are obviously multiple perspectives here, and these two black and white boxes keep us from really seeing potential solutions.

    Bjorn Lomborg for example believes in man-made climate change, but also doesn’t like the alarmism. Although he cherry picks data like he accuses others of, he also I think rightfully points out lots of flaws in the arguments that help us identify solutions. Much of the hurricane damage increase over time is because we’re building bigger and more expensive houses in hurricane alleys; for this problem, we can stop building there; everybody stopping flying altogether until 2100 delays increases the increase by a few weeks, so stopping flying isn’t the solution. Often the solutions are smaller, more local, less sexy: want less polar bears to die? Increase regulation on poaching. (Polar bear populations are up over the past decade because of this, apparently). I would love to identify and popularize these solutions, so they are spoken in the same breath as global warming rather than it being all gloom and doom and end of the world.

    There are real tricky questions about what we’re trying to preserve and for whom, as well. If all we care about are humans and climate migration, then building infrastructure in places like Haiti and even evolving to coal power would be more helpful.

    HOLY CRAP! that is amazing. also i can’t believe that’s not in widespread use… As of now, there are no plans to produce and use the backpack on a large scale what am I missing? There must be some weird/unnamed cost, bc otherwise it’s just essentially free energy....
