The motors are actually pretty well waterproof already except for the bearings. And even those are sealed so they'd likely work for a while (but then probably get rusty over time).

Reply to The internet has become essentially 5 giants sites all sharing screen shots of each other and not much else. by DominosFan4Life69

Sorry, I gotta disagree. Maybe what you say is true if you limit it to "social media" instead of "The internet".

"The Internet" is so much more than just social media.

There are tons of websites dedicated to specific hobbies that have active communities. There are thousands of open-source and commercial software projects distributed online. Computer gaming, videoconferencing, online banking, niche online shopping stores that are way better than Amazon/Walmart/etc., remote access to computers for work, large-scale data transfer, a dozen or more streaming video services, online board gaming by subscription, the list goes on and on...

Reply to 10x20 Shed base materials. by EnuqieuEsur

I'm in the Canadian prairies, so we get real winters. I built an 8x12 shed where the floor joists rest on two pressure treated runners. I dug down into the dirt and made a trench for each runner about six inches deep and 16 inches wide and a bit longer than the length of the runners. Each trench was filled with crushed stone, then levelled, and the runners placed on top.

That was 15 years ago, and it's still going strong. Haven't had any problems with warping/heaving/sinking, but it's possible we're just lucky with ground consistency here.

You'd likely get better drainage by making a raised gravel bed with pressure-treated walls, but that wasn't necessary around here as the water table is low enough.

Reply to comment by Numerous_Vegetable_3 in New Zealand proposes taxing cow burps to reduce emissions by TDYDave2

Here in Canada most dairy farms are definitely industrial entities in the sense that they've got hundreds of cattle and are largely automated.

And we already know that it's possible to significantly reduce cow methane production by feeding them a small amount of seaweed...there are probably other ways as well.

By taxing them for cow burps and then giving them money back if they do the right thing, it provides a financial incentive to do the right thing. This is known as a "Pigouvian tax" in economics.
