  W/r/t the exercise-longevity linkage, a pitfall is determining the direction of causality. I.e., if sedentary people don't live as long as active people, is it because exercise improves longevity, or is it because healthy people are more active because they feel better?

Then thanks to audiobook and epub a must-read-hear-again once a year such as Solaris by S. Lem. A hint: "Reservoir dogs" (movie by a kind Tarantino) moves back and forth. Thanks for the recipe.

  @5:10 so let met get this straight, for 367k you can store energy at 34 cents/wH over 1000 cycles? I tried to compute that into something functional, but it doesn't make sense. Okay apparently it should be sufficient to power 4 homes for several days. I can do that. My home consumes 10kWH per day, so I would need 45 kWH for this equation. I can buy 304Ah LFP batteries for about 90 euro. 48 of them would render me just over 45 kWH capacity. I would need 3 BMS's each around 600 euro each. So a grant total of 6120 euro and I can store those in the corner of my shed. Not to mention they can perform 4000 cycles. Look, don't get me wrong, I love the idea of open source and open research as much as the next guy. I contribute to open source projects myself. But, as please prove me wrong, this feels rather pointless to demonstrate an entire shipping container costing at least 15 times more, taking up at least 25 times the space and has a quarter of the lifespan. Or at the very least please provide additional insight by comparing to a regular cell and pointing out the differences.

  You're not wrong. Every year li-ion gets cheaper. When I started this project in 2017 the economics looked better. That being said, this has zero economy of scale, so it's hard to compare. In general, yeah, I'd buy a commercial solution. This is more of an exercise or maybe in the very long term this is the start of a sustainable solution.

  I think a nuance is that high calorie foods are significantly easier to overeat. If you think about it, eating 3000cal of burgers is pretty easy, but trying to eat 3000cal of fruit is almost physically impossible. But i think you are right, i spoke to a nutritionist and her advice was just the basics, eat what you like, make sure its diverse. Eat at a defecit if you want to lose weight and eat at a surplus if you want to gain.

  Gary Taubes book "why we get fat" talks about a vicious cycle with sugar. We eat it, then have high blood sugar quickly, store it quickly, and get hungry quickly. I think (probably for some people more than others) sugar is a food that produces more hunger. So, yeah, some foods make it harder to lose weight, and obesity shortens lifespan. So there's a mechanism there... But it's strange/interesting that it doesn't really show up strongly in the statistics.

  There is a B style sci fi series called "Dark Matter". In terms of human interaction with advanced robots, it was exactly as I expect. Simply it can be awesome for humanity or deadly and this depends solely on WHO is creating and developing them. Today its corporations developing robots and AI and profits from driving this development (as in the series). My concerns are today, robotics helps corporations grow and profit and adds no value to humans or their lives now or in the foreseeable future. People like Yuval Noah Harari speak on this and the value of residual humans post the commercialisation period and gives a telling insight into the corporate mind from an insider. In short, I think the path of robotics will be beneficial to the upper 10% of society and the rest will get left behind. We will be "the useless class" (his words). My argument is that corporations are the programmers and have little to no interest beyond there own survival. Its not their good intentions or for the advancement of the human race that drives development. As corporations find cheaper, better and more efficient ways to exist and survive human labour will be redundant. If today you think your government will care for you when we hit the tipping point, I believe you are seriously mistaken. There is also a interesting narrative in the series on human social issues in the series - Interesting only if you consider the application and possibilities. I think in the next 10-20 years, those our children will experience will be feudalistic and I'm not sure that can change.

  Voluntaryism. Solidarity is great, but you can get solidarity at church or at a baseball game. Understand that the innate brutality of The State is the essential reason corporations can get away with regulatory capture. Protectionist policies like "trademark" and "copyright" lend the might of the state's monopoly on violence to A) extort its citizens for trillions of dollars and B) enforce rigged market regulations that favor corporations. If there is no state then there is no monopoly on violence to rig by the rich. It becomes a fair fight. And the most profitable and most desirable outcome for the maximal number of people is VOLUNTARY FREE MARKET CAPITALISM. In this scenario, the only people who suffer are politicians, central banks, influence brokers, The Central Intelligence Agency. Those people immediately get sent to a crowd-funded supermax prison where they will live in solitary confinement on suicide-watch forever. Cockroach paste for breakfast, lunch, and dinner. The real humans get to build amusement parks, race tracks, wild-life reservations, and life-sized Gundams anywhere that the ecosphere can support in perpetuity, without any notion or care about "intellectual property" or "trademark". Just people, inventing things that will benefit all of us, for the purpose of benefiting all of us. And then still being able to reap unfathomable rewards that give true meaning and purpose. Reputation. Respect. Admiration. Recognition. That thing we should all want. Not to be famous, but to be truly respected. AND also still make a lot of money anyway in the form of gifts. People do it all the time. People donate gifts to those for acts of courage and selflessness, for benefiting society by volunteer work. I mean, look at the way americans trip over themselves to give free coffee to anyone in a military uniform, splattered in the blood and entrails of Yemeni children. Imagine what you can get for making an Open-Source shareware like Krita or Blender 3D or the Newgrounds pre-loader start button or Stable-Diffusion. Those developers support themselves as computer techs and programmers, but they also receive funds from the non-profit foundations that funds them, which is funded by private donations. That's only the start of it. No, I'm not making a "I can pay you in exposure" argument. I'm making a "Intellectual Property is bullshit" argument.

  Incredible video, with some excellent insight into the Diamond Age. You seem like an awesome guy to talk to, would love to someday. As for my thoughts: Considering this post-scarcity world is implied to be a future after anarcho-capitalism, it is interesting to see the neo-victorians fully embrace the capital system (as imperialist real victorians did) while seemingly presenting as an elite but seemingly reasonable high society away from the chaos of other phyles. After reading Snow Crash, and seeing the chaos of corporations and cyberpunk lawlessness, the depiction of cultures in the story becomes all the more interesting, as the significance of corporations seems to have waned in favour of cultural gangs with nigh-unlimited resources. tldr; I would love to hear your thoughts on Snow Crash.

  @@PeterAllenLab Thanks for the reply! Snow Crash is of course a cautionary tale, of the dangers of full belief in free market capitalism. Essentially the world Snow Crash takes place in is one where equity/assets mean more than anything else. Absolutely not a world I would like to live in, but it is one possible future based on the path of neoliberalism we were set on by politicians in the 1990s. Ultimately I think Snow Crash is a very entertaining look into that sort of sci-fi world with some very prescient insight into the nature of media in our world. The main connection between it and the Diamond Age would be how different the world seems to be a few decades after such a anarcho-capitalist world, as it is implied to be a sequel in-universe. Corporations become more tied in with a wealthy elite, and have their roles replaced by cultural elites that provide basic amenities and products. It seems to be an interesting evolution over time for the wealth to consolidate like it does in the Diamond Age. Not only that, but the book specifically pokes fun at the degeneracy of the western world in this interrim period before the rise of phyles. They (neo-victorians in particular) try to distance themselves from the obvious capitalist greed of the period between the victorian era and the rise of phyles, but still engage with many of the same principles. They try to act as though they have learned a lesson from the world of Snow Crash, but many core issues in this post-scarcity society still remain. There is a lot to dig into in the worldbuilding of these 2 books, and I may be overthinking some of these concepts a bit, but the world stephenson created is absolutely one of the most interesting speculative fiction settings I have ever seen.

  The problem I see with using raw hydrogen from bore holes, there is no natural way to recycle the water it produces. Unlike CO2 which plants can convert back to oxygen, I don't believe there is a natural photochemical process to extract oxygen out of water. If we replace oil with bore hole hydrogen we will slowly be using up the earths oxygen. The amount of oxygen in the earths atmosphere historically has decreased over time and this will continue.

•

  Interesting question. We're converting Oxygen to CO2 and H2O now; I imagine this wouldn't be worse except we'd be tempted to do it longer. At least O2 is an abundant gas. But one never knows. Maybe making a bunch of new water vapor would have some unforeseen consequences.

• 
  @thetatek66342 ай бұрын

  @@PeterAllenLab I was looking at it from the point that plants do the work of converting CO2 back to oxygen for free. We would have to divert wind, hydroelectric, and solar power to convert H2O back to oxygen and hydrogen at a net loss in resources. Granted this only has an impact if bore hole hydrogen becomes a major energy source for an extended period of time. If the world population growth does not stop soon oxygen depletion due to bore hole hydrogen will be the least of the worlds worries.

  You can get solid iron to burn in an oxygen atmosphere... This is a major limitation in the design of rocket engines... The key thing is not the surface area to fuel ratio, it's the surface area to oxidizer density ratio... If you lower the surface area, you have to raise the density of the oxidizer. Your rate of reaction is related to the density. So if you have a certain rate that the heat is being carried away, you have to produce heat faster than that. This is the basic definition of how an auto ignition reaction works

  I think the most important factor is Wh/$ It does not even Matter if the output power is low. If you try to build e.g. a off grid structure, you need to account that it sometimes can be cloudy for weeks and the battery has to last so long. Compared to that, a charge/discharge time of 48h is not a problem as long the battery is big enough.

All that work for 1000 cycles too. I respect the effort btw.

I've found Dragon Skin silicone is the perfect material for noise-reducing plugs (live band rehearsal etc). You can buy a thickening agent to make the silicone even more firm and dense. I see a company is now offering essentially the same thing for over $150 per set. That's insane. I can make 40 sets for that price.

Specially in the forms lithium carbonate, spodumene, and petalite. I dont fully understand it but my understanding is that with the rise of lithium batteries and cars run on them the material has just become too expensive for us to even carry at the clay supply. I wonder if this is related to what you are talking about or another thing entirely. I think lithium is mined, so if there is a finite amount on earth it would make sense for there to become a monopoly on it as soon as it becomes particularly valuable.
