He was barber and while watching news of an oil spill, he noticed like otters and such who swam in the oil getting all that oil in their hair, so he thought he could put the hair from his shop to good use. He experimented by getting a kiddie pool and putting oil and water in it. He then put hair in nylon stockings and tied the stockings together and put it in the pool to see if would absorb the oil. He then pitched the idea to some university I think (can't remember).@@korbindallas4552

Small correction/addition: peat moss is the semi-fossilized stuff dug up from under bogs. It's very unsustainable. Sphagnum moss is the live plant that turns into peat moss when it dies and decomposes in a bog.

@juliabosse14jb

Ай бұрын

Peat moss is just dried peat that is mainly composed of sphagnum and it's sourced from bogs because sphagnum moss is a keystone species for bogs. To fossilize it would need to be trapped under layers of sediment for about 60 million years, slowly turning into lignite. But yes draining peatlands to harvest peat is a big no no

@BreadCancer

Ай бұрын

It's not partially fossilized, it's partially decomposed. Over time with pressure, peat eventually turns into lignite, which is the lowest grade of coal. But that is a different process from fossilization, where the organic material is replace by mineral over time. Natural peat is an unsustainable fuel source due to its low accumulation rate. However "peat moss" as a term can mean both sphagnum moss, or peat composed of sphagnum moss.

Worth reminind everyone that even the most cleaning we can manage still leaves a LOT of damage.

But please, let's try to speed transitioning off oil ASAP

I know I’ve used wool to clean up small oil spills on my property. And while quite a lot of human hair probably goes to waste and could be used for this, there’s far more wool that goes to waste every year. Sheep HAVE to be shorn every year, producing anywhere from 3-14 pounds each, and a lot of this just goes to waste.

Then combine hair nets with boom floats. And hire some people with textile experience to trouble-shoot the weaving and texture viability. Just because a type of hair isn't that good at adsorption doesn't mean it can't be used in mats that absorb instead.

Hi! I'm here to throw off your experiment's data collection! When I clicked on this video and added it to my "Watch Later" list, it was "chicken butt." I am now watching it when it is "wet hair woman." Neither thumbnail had any influence on my choice to watch this video. I am subscribed and watch most of your videos, generally ignoring only the ones which are compilations.

I tried to google it but it just gets more confusing. On one hand hair absorb water (up to 30%), on the other hand hair are hydrophobic. So if I understand it correctly, unwashed hair have a thin protective layer that makes them hydrophobic to some extent, but when you wash them, the layer disappears and hair take water in. Though it still doesn't seem to explain why rain droplets actually soak in, rather then slip down the hair and fall down without leaving any wet spots. What is with the hair and water relationship? Can someone explain it?

@crisfer22

Ай бұрын

There is a lot of variability depending on how open the cuticle is (from damage or just naturally) and I think time in contact with water might also be a factor, so the longer it is the more it swells and that opens the cuticle too. So dry undamaged hair is pretty hydrophobic, wet damaged hair not so much.

I've seen a commercial way back about Native American hair and how it's so absorbent.

Off these, only the chicken poop was explained in how it processes hydrocarbons to completion. I was hoping you would say how the contaminated hair would be processed. Like that it would be sent to be processed by other innovative methods. Yes, chicken poop would be a good source to process the oil cleanup. Yes, researching other poops woulds be worth looking into. I'd start with cow poop. Now why is it that cows are our supposed greatest greenhouse gas releaser? Methane? Find out what Microflora are involved in that. Pigs. How about geese and other fowl? Bats? But I'd first check out pigs and cows because they poop so much. But chickens are a good idea because of all the chickens we farm and eat. What to do with all the chicken poop? Put it in with earthworms: red wiggler compost worms and nightcrawlers which aerate soil. Stuff that red wigglers eat becomes pathogen-free and makes black gold "magic" compost for gardens. Next, see if organisms shown to eat plastic will work on sopped - up oil spills. Like mealworms and wax moth grubs. Most important, though, is to make sure the organisms that eat oil and plastic truly return usable, food-worthy nutrients to the spil. For that matter, have humans developed any microflora that reduce the plastics in our system? I.e.,should we have more plastic in us than is found?

I don't see why you compare hair floats to booms. Isn't booms a containment system, while the hair floats is a collection method? So, don't they have to be used together anyway?

IS THERE ANYTHING THE HUMBLE CHICKEN CANNOT IMPROVE??

Peat moss is a fossil product (made by nature through geological processes converting biological matter far slower than it's already being used) generally taken from delicate ecosystems, so human hair sounds like a better avenue. Save the peat for where we don't have good alternatives. Still, however we clean up the negligent releases, the liability of all these risks and costs has to be shifted from society as a whole onto the ones profiting from oil extraction. Not just the occasional spill cleanup operations, but the evacuations, the lost biodiversity, the infrastructure that needs to be set up to respond to these events, the 'regular' ongoing climate change, the air pollution, all of it. We can't keep letting companies outsource their negative externalities onto everyone else. Even if you don't care about the environment or public health, that's somebody else using a distorted position in the market to divert money out of your pocket and into theirs by forcing you to pay for the consequences of their business practices. Everybody should agree that's bad. The basis of even the most hardcore 'free market' economics relies on the strict assumption that that doesn't happen (more realistic models on the explicit notion that it "wouldn't be allowed to happen" by the government), the math they use to declare their system 'optimal' explicitly doesn't balance if it it's possible to do that (or for your business decisions to provide an uncompensated benefit to a third party eg. by building beautiful buildings instead of cheaper ugly ones, but that's another issue)!
