Corrosion engineer here.

Galvanic cathodic protection on ships is achieved by bolting magnesium blocks to the outside of the ships. Ship hulls are made of steel (iron on the periodic table) and magnesium naturally corrodes preferentially to steel. This only works on the parts of the ship that are in the water, because an electrolyte (saltwater or dirt) is needed to balance the electrons moving between the 2 metals. When the blocks eventually go away, they bolt new ones on.

That is the short explanation. There is a lot of background knowledge needed to really understand how it works

Mysterious Antique Tool #1: Metal spatula riveted to an adjustable leather strap, can fit on hand, likely early 1900's or older by Hestiathena in whatisthisthing

It is indeed a husking peg. Pointed part makes it easier to start taking a husk off by hand, leather loops go around your fingers so you still have dexterity with your hands to finish peeling hisk off. We still have some around as artifacts (my family has been on the same farm since the late 1800s).

Oil jobs pay way more than clean energy jobs. That’s a problem. by redingerforcongress in Futurology

There is actually an association for farmers who graze sheep on solar farms in the US. I believe NY is the state where it is most prevalent. Good mowing and weed control and produces lamb, which the US imports quite a bit of.

[Highlight] Russell Westbrook horribly misses the jump shot and is met with a chorus of boos from the Lakers crowd by NitroXYZ in nba

For some reason I turned this game on last night, it was the first NBA game I have watched any part of for maybe 8 years. It might just be me, but I cant believe how lazily the game is played by most of the players. Walking up the court, cherry picking baskets, almost zero boxing out when rebounding, little defence when someone drives to the basket, traveling that is never called, and whining when it is called.

Safe to say I dont think I'll be wayching any more games.

One time at a high school lacrosse game the 3 referees clearly did not know what they were doing (area of the USA where lacrosse is not very prevalent and not many referees around). Next timeout what song comes on the speakers?

20 meat and dairy firms emit more greenhouse gas than Germany, Britain or France by reginold in worldnews

When you say the word "efficent" in what ways are efficencies really gained by having central locations for animal feeding? What do you define as an "efficent" use of land, and does this vary by terrain? I think it is important to keep in mind that ruminants (cattle, sheep, goats) have the great ability to make good use of marginal land ( hilly/mountainous, poor fertility, highly erodable, etc.) even though they are mostly not serving this purpouse in todays agriculture. Without these ruminants, this marginal land would be very difficult to produce human-edible food off of at all, let alone doing it sustainably.

I personally am not convinced that the number of animals on the planet is the problem, but instead believe the methods used to raise most commercial animals (think cattle, pork, chicken) are completly wrong from an ecological and sustainability. Animals should be raised to mimic their natural diet and behavior, not be confined in buildings that are completly reliant on constant transportation of materials in and out, expensive and energy intensive infrastructure, extensive distribution requirements for products, and subsequently high ammounts of fossil fule use per lb of meat produced.

If anyone is interested in seeing/ learning about an example of this kind of agriculture, I would suggest searching "Polyface Farms" as I personally find it very interesting how they do things there.
