  • Its not the question you asked, but Nuclear plants can raise the temperature of the bodies of water they use for cooling nuclear plants. Additionally climate change is reducing water availability needed for nuke plants which is something I don’t hear the nuclear advocates talk about when we’re facing a dryer and hotter future. We’ll have to start turning off nuclear plants right when we need them.

    This is already happening occasionally in the last decade:

    Lochbaum analyzes reports from the NRC showing when nuclear plants scale back generation because of warm water.

    In June, nuclear plants in Georgia, South Carolina and Pennsylvania scaled back their generation multiple times because of hot temperatures warming their cooling water. The Limerick power plant on the Schuylkill River near Philadelphia has scaled back because of high temperatures frequently over the past decade, according to the reports.

    The Dresden and Quad Cities plants in Illinois had to scale back because of high water temperatures multiple times over the past five years. The Duane Arnold plant in Iowa and the Monticello plant in Minnesota also reported scaling back generation because of temperatures.

  • Correct me if I’m wrong. I know that Canadian home prices are bonkers, especially in large cities like Vancouver or anywhere in the GTA (are the Quebecois also having this trouble?). However, the problem with Evergrande isn’t just failure of this company reduces home prices (which is where lots of Canadian savings resides), but Evergrande had taken deposits for tens of thousands of homes it never built or never completed.

    So while the value/sale price of a home in Canada may be falling. At the end of the day it still does have value monetarily, and still serves a vital function of housing a family.

    China’s situation with Evergrande means the money paid for the house by the owner simply evaporated with no possibility of a refund and the house doesn’t exist because it was never built (or never completed). So to me the China situation looks significantly more dire.


  • is a symptom of a deeper malaise in the Chinese real estate market.

    Its even worse than that because retail investors in China use real estate as their primary investment vehicle. Where as someone in the USA might put money in a 401k for retirement or a brokerage account for investing, those don’t exist (in the reliable way) in China. So many regular people’s nest egg is tied up in real estate. So this isn’t just the real estate market getting wiped out, its millions of working class people’s life savings just evaporated.


  • Why are all gym memberships like this? The first thing I check before starting a service is how easy it is to end it. I’ve not been able to find a single gym with reasonable terms.

    I do the same. So many gyms have abusive terms which is an immediate deal breaker for me.

    There are handful I’ve found that aren’t bad offering true month-to-month service. Give notice by phone or email by X day of the month and your membership ends at the end of that month. Miss that date? You only have one more month beyond that then.

    For years Planet Fitness had a good deal they’d only run for a couple of days a year where you could prepay for the entire year for $99 (or later $120). You didn’t give them your bank info, no “credit card on file”. You could literally hand them the cash and 365 days from that day your membership would expire with zero action on our part. That was the best membership deal I’ve seen yet. I don’t know if they still do that.

    In the meantime, one could always pay with a prepaid card and then just never add funds when you decide to quit. Then just “return to sender” any mail they try to send you.

    If you’re using your real name I would imagine they’d send the debt to collections which would cost you even more when your credit score tanks and you try to buy a car or house.


  • In all fairness I’m speculating on this too, so feel free to poke holes in my argument.

    We probably need to refine our goal question a little bit. Is it:

    • How fast (can the person in OPs question with OPs conditions) get in the shortest amount of time, such as a sprint?

    or

    • How fast (can the person in OPs question with OPs conditions) get in the irrespective of the amount of time?

    I imagine you could run, but you’d lean over much more towards the horizontal - like maybe 45° or lower, so each ‘step’ would be a push backwards in line with your longitudinal axis.

    What you’re suggesting is matching the amount of effort to move to the body with the position of the center of gravity on the body to be closer to equal to on Earth. I don’t know the math here.

    This might work toward the sprint scenario. However I think we’d run into in efficiencies in our physiology toward the other scenario. Walking or running for bipeds like us means we lean forward to move our center of gravity in a space in front of us. We’re essentially falling forward, and moving our feet under that center of gravity so we don’t fall down. On Earth a sprint might move our body’s center of gravity up to the upper part of our chest, like this runner here where I’ve put the red line:

    With only 1/6th the gravity you’d need to move the center of gravity WAY farther forward to the top of your head (and beyond?). At the lean you would have to have, would you even be able to draw your knees up to your chest, or would they drag on the ground as you move your leg forward to take the next step. Then the body mechanics wouldn’t match our evolutionary advantages for running, but closer to climbing a ladder or running up very steep stairs. While we can do those things, our physiology isn’t really optimized for it.

    Further, we don’t have the ability to perfectly translate all of our motion forward. Some of it is going to go up. Not much “up” would mean we lose friction with the ground and have to wait to fall back to re-engage to impart more forward motion.

    Do these two things together mean that because our center of gravity is so far forward, and errant “up” motion would cause us to fall flat on our faces? Certainly we could dial back the forward motion to prevent the fall, but at that point perhaps we aren’t leaning very far over, and therefor aren’t moving forward very fast with each step.

    Here’s some work from the Univerity of Alaska explaining the physics of running here on Earth I used for reference in forming my opinion source

    Full disclaimer, I am NOT a Kinesiologist, doctor, or physicist. I have no credentials of expertise in this area. I’m just some dude on the internet. Take everything I’m saying as suspect.


  • Well since there’s only 1/6th the gravity an zero atmosphere you can’t really “run” as you do on Earth anyway. Even walking is moderately difficult. Astronauts that walked on the moon found it easier to hop for great distances or shuffle for short distances.

    However, if your question is “How fast could the average person move horizontally across the moon surface?” then it likely comes down to how fast they can hop forward, and continue to hop landing on their feet without stumbling and falling down. Since there’s no atmosphere the only friction to slow you down is the times your feet are in contact with the ground for the hop. So you could likely hop horizontally faster and faster and faster until you get exhausted from hopping or you don’t land right and hop and stumble and fall down. Likely pretty fast. Much faster than a top athlete running on Earth if you practice I bet.




  • There are a number of “levers” that a nation has to influence its economy. Here’s a really simplified version. The biggest lever on one side has low interest rates, and when you swing it to the other side is high interest rates.

    When you want your economy to “heat up” or increase in activity, you swing the lever to “low interest rates” - Depositor’s (you, me, and corporations) money sitting safely in banks now earns a lot less interest. So a company is not making very much money just letting it sit. Companies will look for things they can remove their money from bank for and invest in (new businesses, hire new workers, expansion, research & development on new products). This ultimately means the money is spent to buys things. If everyone is doing this same thing, the price for things to buy goes up. There are more buyers than product. This is inflation, which too much, is bad for your economy. So what do you do when you now have high inflation and the value of your money is going down (because it takes more money to buy the same thing you bought before)?

    When you want your economy to “cool down” or decrease activity, you swing the lever the other way to “high interest rates”. Companies see they can get great returns just by stuff their money in a bank and it is a super safe investment. Suddenly all of that spending that was happening in your economy to buy things for expansion, starting new business, or hiring additional workers dries up. The rise of prices slows, and given enough time, halts.

    So who moves the lever? How do they know when to move it? Which side do they move it to? How long do they let it sit at that setting before they move it again? How do they know when to do that second move?

    Federal bankers who are economists that watch for market trends and economic indicators. It is much more art than science. When they do their job well, you don’t even notice. Things just get good. When they don’t do well, your entire country feels it and daily life is massively affected. People lose jobs, houses, and have trouble feeding themselves.


  • For those not familiar with this language a “basis point” is .01 of a percentage point. So in this example:

    “Turkey’s central bank on Thursday hiked its key interest rate by another 250 basis points”

    …would mean an interest rate hike of 2.5%.

    To put that into perspective, the USA’s Prime Interest rate (which mortgages, bank loans, and credit card rates are derived) is currently 8.5%. If the USA raised the Prime Interest rate by 2.5% making Prime Interest rate 11% there would be huge HUGE economy impacts. Entire industries overnight would become nonviable. The slow home sales right now would grind to a near absolute halt. Millions of Americans that are servicing revolving debt would see their monthly payments see large increases.
