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?

I discovered this book by pure chance, in Italy from the cover. And since then, I am fond of Cheradenine Zakalwe/Elethiomel. 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.

Very interesting video

@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.

One of my all time top ten favourite books. Love your breakdown. You managed to demonstrate how fascinating and profound the book is without even discussing the pedagogic relationship between The Primer and Nell. (For me the “heart” of the book. ) If there were an even longer and more in depth review I would watch that too. Thank you.

Unless your that guy on super size me.

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.

Any updates on this?

Use of Weapons is my favorite book of all time, and it was really fun to go through it again with this video. Thank you!

get a dog and walk it.

Interesting. I like how much leeway my body gives in what I can put into it. Thanks God

well ill be dam

The saga continues! *rubs hands gleefully*

Great video. First one that actually goes over both processes and compares the final result. Much appreciated.

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.

<3 very well made video!

this dude rocks!

I'd be happy with a robot capable of doing housekeeping... no more than that is necessary. Go on...

The capitalist model is over or it's going to be a very disturbing scenario.

8:38 The army's new M7 actually was built for the fancy new .277 Fury cartridge. Made by the same company that built the rifle, Sig Saur.

This -- "Let's consider what [...] technology does but focus on who it does it for and who it does it to". Allocation of robots is a direct analogy to allocation of resources.

Great analysis. I was born in 1980 and productivity is up my entire life (I believe through the adoption of computers), but wages are stable when adjusted for inflation. Labor saving devices should be a source of celebration, but instead workers suffer for it.

love the new video's dude. i lost track of the iron battery hope it went well

I suspect this is the kind of thought experiment that should be performed in a fume hood.

Thanks Mr. Peter Allen. Your are right. Robots and artificial intelligence technologies are only favored by the ignorant, lazy, and unscrupulous. And they are the ones who destroy society by encouraging others.

If Musk's robot can make a copy of itself in a day and if they have the parts it would be possible to produce 6 billion humanoid robots in 34 days... Once robot's go mainstream we will have 95% unemployment, why employ a robot with it's pesky human when you can just employ 2 robots.

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.

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.

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

what about using a peroxide?

just raise the temperature of the reaction above the boiling point of iron oxide. ezpz. only problem is finding an oxidizer that's stable past 3400c lol. dont mind that you're also dealing with iron gas too

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.

How about using a bike pump needle to inject pure oxygen between the glass plates? It shouldn't be too hard to get a regulator and an oxygen tank from a local welding supply store

So while lead acid is about ~30 Wh/L, 0.25Wh/L still leaves something to be desired. I think it means that in order to replace a lead acid battery with an iron battery to get the same energy we would have to have 4x30=120 iron batteries of the same size? All that work for 1000 cycles too. I respect the effort btw.

Would it work to purge your system with pure oxygen? If simply changing the atmosphere works, you can avoid the issue of ox flow removing the heat.

Could hot water vapor be used somehow?

I have for years made my own by making an initial positive with Radians then using Smoothon Dragon skin to make formal molds. You can then make as many new positives with Dragon Skin silicone (you'll definitely need EZ Release as to not bond Dragon Skin to Dragon Skin) as you want. 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.

Thank you for sharing.

Bravo, the ways of the world explained. The yins and yans are all that really have to be told to all.

I do ceramics, a lot of it. This video was great to watch, and it got me thinking about something that has become scarce in the ceramics industry that has a lot of people bummed: lithium. 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.

Ok I like you, sub. Thanks for talking about the feudal values

Good sir, you have described (in detail) my personal infatuation with Aluminum. (I wasn't even fully-aware, until this presentation)

0:26 Wrong. Value comes from people preceiving something as desirable and worth owning. Whether that thing has the slightest bit of practical value or utiliy is a whole other question.

Even as a small child I recognized this as we dont work to help each other and further ourselves.

It's the jews

Well said. We have a lot of work before we are to dissolve the illusion of scarcity and debt based economics as a species. It may be the most pressing matter humanity faces at present? Almost an ecological limitation nature has designed to preserve a universal equilibrium like Thermodynamics? Before we can weild the power of interstellar travel, we must understand how energy and information flow on our terrestrial home first. This would prevent radical species becoming a sort of cancer in the cosmos. Unfortunately, this postulate falls more under the category philosophy and spirituality as it would be challenging to prove emperically. 😅 Appreciate you and having voice of reason to my perception of our shared reality. 🍻

Beautifully constructed video

subbed

I went from/to Cool a video about aluminum chemistry -> oh wow this is really great I need to start doing some aluminum casting for daily life things -> *rethinks everything about life and what is righteous or not and what is one's role in society and within his own life
