To save everyone a lot of time: he finds that a sintered bronze bearing has worn and allowed metal-on-metal contact elsewhere in the unit. He theorizes it's the oil, which he demonstrates is very thin at room temperature. Which is meaningless - film strength doesn't have to be high if there isn't high pressure between sliding surfaces. The claim that fridges from the 40s and 50s were very efficient is nonsense. Even a 10-20 year old fridge is very inefficient compared to a modern fridge. It's as easy as looking at energy star ratings. > When it becomes a problem, it goes to the dump where all the foamed-together plastic parts will not be feasible to separate nor recycle. It's never been economical / feasible to manually take apart an appliance for recycling. They're shredded and the plastic/metal chunks separated mechanically for the raw materials.

Old refrigerators may not be as efficient, but they were built better internally and last longer. The savings from an efficient refrigerator that only lasts a few years is meaningless.

You'd have to stick an ammeter on it, but I bet a 50s fridge is pretty efficient because they are manual defrost only. Most modern full-size fridges are auto defrost – essentially they suck down electricity to heat up the cooling system. The efficiency gains over a couple decades ago are due to moving from fixed, mechanical timers to computer controlled adaptive defrosters.

  >I bet a 50s fridge is pretty efficient because they are manual defrost only That doesn't seem like a fair comparison. It's like saying a bike is "pretty efficient" compared to an e-bike because it doesn't consume any energy (infinite efficiency!)

Even a 10-20 year old fridge is very inefficient compared to a modern fridge. It's as easy as looking at energy star ratings. Do you think the manufacturers aren't gaming those ratings either? The energy efficiency of fridges over time has definitely not been monotonic either. The ones that use the most were the late 60s-80s models that sacrificed insulation thickness for more interior volume.

  The problem with many energy efficiency ratings, including Energy Star and that controversial California "ban gaming PCs" one, are that they are designed around "power consumed for a particular use case", where use case is defined as "watch TV for the household average number of hours per day", not normalized for whether the picture quality was great or poor. In the gaming PC case, there was a bureaucratic formula based on how many ports the computer had, and having lots of ports allowed you to use more energy because it was considered a "high expandability" computer, regardless of whether it was reasonable for the computer with empty extra ports and no different parts to use more power. And it focused almost exclusively on "turned off or standby" power, not power in use. In the case of TVs, manufacturers game the numbers by rating efficiency "as shipped to the consumer at factory default settings." The manufacturer just sets the brightness to 20%, and throws a warning on the screen if the customer tries to change it, saying "the TV may use more energy". Of course, in the store, the TV is set to Store Mode, which means the brightness is often even higher than 100%, and the TV has a sticker about how efficient it is. Nobody would buy a TV that was dimmed permanently to the Eco Mode, but technically, you can "watch the very dim TV", so it counts. This means that the composite "energy efficiency score" is not calculated with "output" or "work done" or "function realized" held constant. The text of the standards often does not define exactly the outcomes to be achieved. Thus, it is entirely possible for a manufacturer to produce products with a degraded functionality in exchange for "better energy efficiency", regardless of whether worse functionality may cause the consumer to use the item for twice as long. (i.e. some government restricting the wattage of vacuum cleaners, which may cause vacuum cleaners to become less effective instead of more efficient, causing increased run time) In the case of fridges, you might imagine how a manufacturer might skimp on "lasts long", "how much space the fridge takes compared to how much space is inside", and other things like this.

> They're shredded and the plastic/metal chunks separated mechanically for the raw materials. The plastics recycling industry is over 90% fraud, just like the carbon credits market. There are thousands of cases of Australian garbage turning up in indonesia with trash bags marked with the name of the local authority responsible for managing it. Plastic from UK is either burned in Poland to power cement production, or is sorted in Turkey and send to the third world to kill children and sea turtles. I throw plastic in the trash to make sure it never leaves the country, but stays here and goes into landfill and doesn't hurt anyone. And to make sure the true cost of disposing of it is paid.

  >The plastics recycling industry is over 90% fraud [...] >Plastic from UK is [...] sorted in Turkey and send to the third world to kill children and sea turtles. So in other words, they're sending recycling to third world countries to be sorted because the cost of labor is cheaper, and those countries have bad waste management practices so the unrecyclable materials end up in rivers or whatever. I guess this counts as fraud if you think that putting something in recycling means that it'll definitely be reused somehow. Many people might even legitimately hold this belief. However, if you do a little bit of thinking you know this is an impossible goal/strawman. For one, people frequently miscategorize their recycling, which means things that can't be recycled end up in recycling. Obviously those won't be reused. Also, no recycling technology is perfect, and there's bound to be something that gets up too degraded/contaminated to be properly recycled. Meanwhile, I'm not aware of any active efforts to portray recycling as some sort of 100% perfect waste remediation, so I'm not sure where the fraud angle is from. It's a case of mismatched consumer expectations at best.

    > because the cost of labor is cheaper, and those countries have bad waste management practices... If you are running any kind of business, say house insulation, you take money to fully insulate a house, don't insulate 90% of the house, and then attempt to mislead the customer into thinking the job is done, you have commited fraud or embezzlement. If these companies are paid to recycle but recycling is not happening, then someone has commited fraud. Also the contract does not say 'you can dump unresycleable stuff into the ocean' - they are suppose to dispose of it properly. It is their job to audit their supply chains and to make sure the job is done. If I know from public sources that majority of plastic that goes to their contractors in Turkey are commiting fraud, then a company with an army of lawyers knows it too. If they continue using contractors in knowledge that their contractors are fradulent, but are telling me that plastic is being recycled, they are defrauding me. When major western media publishes a video of masked armed men chasing their reporters in Indonesia for investigating 'recycling', it should be clear to anyone that this is massive organised crime. You don't get to blame this on 'those countries' because our countries are not doing shit either. We created the problem and we outsourced it by contracting literal mafia in Indonesia. Your taxpayer dollars are used to pay mafia bosses and to bribe Indonesian officials, sponsoring corruption in 'those countries'. This is not just my opinion, there have been multiple investigations and convictions for recycling fraud. https://www.gov.uk/government/news/brothers-sentenced-for-148-million-electronic-waste-fraud https://www.gov.uk/government/news/brothers-sentenced-for-14... https://www.theguardian.com/environment/2018/oct/18/uk-recycling-industry-under-investigation-for-and-corruption https://www.theguardian.com/environment/2018/oct/18/uk-recyc...

  Is compressor not evolved from 50s? Looks hard to believe. Isn't modern refrigerators use inverter compressor? I suspect that some other improvements exists.

    compressors have only two simple characteristics, compression ratio and volume. A fridge doesn't require anything special and is essentially the same piece of metal since the 50's exept theres probaly alot less metal in modern ones.

      Not true, if you can compress a real refrigerant slower you get better performance; modern control systems that can ramp up and down are significantly more efficient than older on-off styles.

And also, if anyone actually reads the page linked - just below his post you can see a reply from an appliance repair shop, stating that they repair about 1500 refrigerators a year, and they see maybe one compressor failure a year - further stating that modern compressors, even with their shitty design, are still the most reliable part that will outlast the rest of the applience by a mile. And yeah, I agree with them actually - there's no way 1950s compressors had such low failure rates. I do recall seeing an american ad for some oven brand from the 50s, where the leaflet advertised that an average consumer shouldn't expect to repair it more than 2-3 times in a 5 year period - and that was advertised as a selling point!
