This article reads like a press release.

CrimeDad , in Here’s how Michelin plans to make its tires more renewable

Something to keep in mind is that trains don't need tires.

autotldr Bot , in Here’s how Michelin plans to make its tires more renewable

This is the best summary I could come up with:


We balance it across three domains: the people, the planet, the profits," Michelin North America President and CEO Alexis Garcin said during a presentation.

The "People, Planet, Profit" principles emphasize eco-consciousness but also remind everyone that Michelin is a company that needs to make money to keep tires rolling off the lines.

This is a vast improvement over companies that unveil unrealistic, feel-good items that won't ever see production.

It had a lower rolling resistance, allowing drivers to potentially save money on gas and reduce their carbon footprint (although, to be fair, most probably didn't think about that).

In 2019, it introduced new racing tires for IMSA's WeatherTech Sportscar Championship that used 30 percent renewable and recycled materials, with no real drop-off in performance.

The higher the abrasion rate, the more particulates are left on the asphalt, which migrate to the soil and eventually end up in the water supply.

but have they tested it against various types of wear and tear, environmental exposure, being hit by an american truck or other large damage, water damage from a toilet overflowing and going unnoticed for a couple months, other stuff...

Obviously not yet, but given that similarly build churches have survived hundreds of years and multiple heavy earthquakes, I would say chances are high that it will be quite durable.

For water damage it would be probably more durable that regular concrete construction, as this mainly damages the rebar reinforcement, which can not be easily inspected for damage.

One approach to this is lightweight construction: the thinner the ceilings of a multi-storey building, for example, the more space is left for extra floors.

Given the way these are suspended and that you can fill the empty space with noise dampening material, they might be significantly better than normal concrete floors regarding noise transmission.

... "using 3D printing – but instead of concrete, they used sand combined with a binder." ... o.k.

So.... Mortar.

IT'S TOTALLY DIFFERENT BRO

Skua ,

Concrete is something like a tenth of humanity's total CO2 emissions, so if this is something that lets us use less concrete then that's actually great

Plus structurally, even if it were off-the-shelf concrete vs mortar, it's still structurally different, so I'm sure that also makes a difference.

Mostly I was just making fun of the phrasing and distinction without actually clarifying the difference.

How does concrete emit CO2?

Skua ,

The process of making it involves cooking limestone until the carbon dioxide comes out, basically. Limestone is CaCO3 (one calcium, one carbon, three oxygen). Cement requires lime, which is CaO (one calcium, one oxygen). That leaves a C and two O, which stick together on the way out

Pretty clever, and I like how organic it looks. Come to think of it, wasn't H.R. Giger also Swiss?

Guess they like those organic designs.

Varyk ,

Freaks me out if there was a little plaque explaining it before I went into the building, but if it works, no one's going to blink an eye.

Sounds like the right kind of retrofuture tech to me.

evasive_chimpanzee , in Wildlife psychology - understanding animals reaction to human noises

The effect of larger shipping noise on whales is something we don't talk enough about. Also, there seems to be a bit of a gentleman's agreement on sonar usage to avoid power/frequencies that would be really harmful to whales, but the moment one countries breaks that agreement, they will have a leg up because they could get better long range and more detailed data on the movements of another country's navy.

There have been isolated test events that have lead to mass whale suicide.

paysrenttobirds , in Wildlife psychology - understanding animals reaction to human noises

This is really interesting to me from the angle of why do some species coexist with humans in suburbs, etc, but others are pushed aside by development. I'm sure there are many factors, but I think sound is a big one. I wonder if it's possible to teach a population of a skittish species to be comfortable with suburban life over a few generations.

keepthepace OP ,

The deers of Nara show that giving them food and protecting them is an easy way to achieve that.

I had never seen deers as aggressive as monkeys towards humans!

Thank you, I never knew.

That looks like poop in a bag. Should we be lining our walls with poop in a bag? TLDR: it wasn't poop in a bag.

reddig33 ,

Pretty sure Adobe brick is made with poop. And it insulates well.

DeathbringerThoctar ,

When people say "Adobe is shit" that usually mean the software not the building material.

Tylerdurdon ,

Now you know there's multiple layers to the joke, and knowing is half the battle.

autotldr Bot , in “Energy-smart” bricks need less power to make, are better insulation

This is the best summary I could come up with:


Researchers at the Royal Melbourne Institute of Technology (RMIT) in Australia have developed special “energy-smart bricks” that can be made by mixing clay with glass waste and coal ash.

It mostly contains fine pieces of glass (92 percent) left over from the recycling process, along with ceramic materials, plastic, paper, and ash.

Based on bricks produced in their lab, they estimated that “each firing cycle led to a potential value of up to $158,460 through a reduction of 417 tonnes of CO2, resulting from a 9.5 percent reduction in firing temperature.” So basically, if a manufacturer switches from regular clay bricks to energy-smart bricks, it will end up saving thousands of dollars on its power bill, and its kilns will release less CO2 into Earth’s atmosphere.

“Bricks characterized by low thermal conductivity contribute to efficient heat storage and absorption, creating a cooler environment during summer and a warmer comfort during winter.

This advantage translates into energy savings for air conditioning, benefiting the occupants of the house or building,” the study authors explained.

Tests conducted by the researchers suggest that the residents of a single-story house built using energy-smart bricks will save up to 5 percent on their energy bills compared to those living in a house made with regular clay bricks.

boatsnhos931 , in DIY Supermaterial Could Save You From Heatstroke: Salt based PCMs

That's Ted Cruz lil bro

MonkderDritte , in DIY Supermaterial Could Save You From Heatstroke: Salt based PCMs

Can't look videos, what is the recipe?

ProdigalFrog ,
@ProdigalFrog@slrpnk.net avatar

@Longpork3 wrote down the recipe here.

1.2l water

240ml sodium sulfate

60ml sodium chloride

20ml xantham gum(optional for increased efficacy by keeping the solution homogenous)

Boil water, stir until fully dissolved, a small amount of solute should remain, if not, increase sodium sulfate concentration slowly until it does, indicating no free water molecules available for dissolution.

Solution should now be cooled to below 18c( freezing point) for an end product that will regulate temperature to 18c so long as it have sufficient(negative) thermal energy.

Solution of pure sodium chloride will have freezing point approx -20C, while solution of pure sodium sulfate has freezing point +35C. Adjusting the ratio of NaCl to Na2SO4 will shift the freezing point towards either end of thag spectrum, depending on what phase change temperature you are targetting.

MonkderDritte ,

Thanks!
