This thread is for large-scale improvements or even small tweaks in society that are impossible to implement under capitalism. Inspiration for this thread came after reading this
>Today, we have insight into why a person handling copper day in and day out would have protection from a bacterial threat: Copper is antimicrobial. It kills bacteria and viruses, sometimes within minutes. In the 19th century, exposure to copper would have been an early version of constantly sanitizing one's hands.
>A study from 2015 found that a different coronavirus, human coronavirus 229E, which causes respiratory tract infections, could still infect a human lung cell after five days of being on materials like teflon, ceramic, glass, silicone rubber, and stainless steel. But on copper alloys, the coronavirus was “rapidly inactivated.”
>So given how well it could work, for hospital infections and for health more generally, why isn’t copper everywhere? Why isn’t every door knob, every subway rail, every ICU room, made of copper? Why can we easily buy stainless steel water bottles, but not copper? Where are the copper iPhone cases?
>There might also be a perception that copper is too expensive, Schmidt said, despite the fact that the numbers indicate it would ultimately save money. One of Keevil and Schmidt's studies from 2015 did the math: The cost of treating an HAI ranges from $28,400 to $33,800 per patient. Installing copper on 10 percent of surfaces cost $52,000 and prevented 14 infections over the course of the 338-day study. If you take the lower end of the HAI treatment cost ($28,400), then those 14 prevented infections saved a total of $397,600, or $1,176 a day.
So while the material and reason to use copper for most things are there. The kind of short-term market logic that makes it impossible to do anything about climate change also prevents this move from being made.


Clicked for the image it looked like tits in a bra.

Left disappointed


Replace fossil-fuel products and oil derivatives with hemp. Fuels, plastics, building materials, can be all made from hemp. "Hempcrete" is 6x lighter than steel, while being 10x stronger. We can build recycle-able houses out of hemp. Ford built a car partially out of hemp, and it could take hits from an axe to the body without leaving a dent (sure, now we know crumple zones are important, but the material can absorb more force, which would make for better crumple zones). There are tens of thousands of products and materials we can make out of hemp, but we don't because hemp was a threat to paper (and oil) corporations in the US in the 1920s and 1930s.

But how did the US force the world to make hemp illegal? 🤔 Was it in post-WWII reconstruction and Marshall Plan?


holy shit same
why are we so horny


interesting idea for a material that would cool things and do away with a lot of air conditioners
Although I wonder how much energy it takes to produce


> 3. It is necessary, in the third place, to ensure such a cultural advancement of society as will secure for all members of society the all-round development of their physical and mental abilities, so that the members of society may be in a position to receive an education sufficient to enable them to be active agents of social development, and in a position freely to choose their occupations and not be tied all their lives, owing to the existing division of labour, to some one occupation.

>What is required for this?

>It would be wrong to think that such a substantial advance in the cultural standard of the members of society can be brought about without substantial changes in the present status of labour. For this, it is necessary, first of all, to shorten the working day at least to six, and subsequently to five hours. This is needed in order that the members of society might have the necessary free time to receive an all-round education. It is necessary, further, to introduce universal compulsory polytechnical education, which is requiredin order that the members of society might be able freely to choose their occupations and not be tied to some one occupation all their lives. It is likewise necessary that housing conditions should be radically improved, and that real wages of workers and employees should be at least doubled, if not more, both by means of direct increases of wages and salaries, and, more especially, by further systematic reductions of prices for consumer goods.

>These are the basic conditions required to pave the way for the transition to communism.

>Only after all these preliminary conditions are satisfied in their entirety may it be hoped that work will be converted in the eyes of the members of society from a nuisance into "life's prime want" (Marx), (8) that "labour will become a pleasure instead of being a burden" (Engels), (9) and that social property will be regarded by all members of society as the sacred and inviolable basis of the existence of society.

>Only after all these preliminary conditions have been satisfied in their entirety will it be possible to pass from the socialist formula, "from each according to his ability, to each according to his work," to the communist formula, "from each according to his ability, to each according to his needs."


Doesn't copper oxidize, effectively having to be replaced every 10-20 years because it's surface wouldn't inactivate viruses anymore?


i wonder if you could just sand/scruff the surface??


No, read the piece
>Another reason copper may have been passed over for steel, plastic, or glass is that it can easily tarnish and requires a lot of cleaning to remain shiny. “But copper is antimicrobial regardless of how grody it looks, if it turns green on you, it still has the ability to kill bacteria and viruses and fungi,” he said.


Whales are one of the best ways to sustainably store carbon away from the environment because they eat a lot and then sink to the bottom of the ocean.

Why are whales going extinct? Over-fishing, pollution, lots of reasons

>Now we turn to the economic side of the solution. Protecting whales has a cost. Mitigating the many threats to whales involves compensating those causing the threats, a group that includes countries, businesses, and individuals. Ensuring that this approach is practical involves determining whales’ monetary value.
