I’m looking forward to this. May be a one time event in my life.

After reviewing my earlier posted link, I think that link is all fabrications, as they have so many in their Subscribed area. Anyway, was cool for a bit.
Now I go back to the papercrete videos, for me.
I had an epiphany of sorts the other day, as I was feeding my worm bins, of all things.
The bins are close to giving me around 30-40 pounds of wonderful rich EWC!!
However PLASTIC so much of it, everywhere in my life!
Fucking plastic is everywhere, it encases my worms, as the totes are plastic, it encases my freshly cracked open beans, they STAY in cased in plastic until I cull them!
Plastic walls (Panda film) , plastic watering totes, my mix of medium always encased in plastic!
Now I want to start making pots and what not, from paper and card board waste, since I grind up for my worm medium, all from our recycling bins, after buying a really good thick sheet shredder.
I have an excess of the paper/carboard shreds, so papercrete here I come.

I am hoping to see it along with you, @Bert.

This is going to sound weird, but it turns out those soaring birds don’t breath the way mammals do. WTF does that even mean?! Told you it was going to sound weird.

Add kites to the list of soaring birds. They are amazing fliers.

I see a report this morning of the Earth’s core slowing its spin. Wondering how that’s gonna play with the Magnetic fields.

This is a good thing because I’ve been getting dizzy.

Of course it’s old stuff. It’s early 20th century!

Something I didn’t mention about the place is they were early American supporters of electrical generation. They had their own generator (HUGE by today’s standards, of course, it occupied an entire large room) and made their own power. As I recall, it was DC, though I’m not sure about that.

We are certainly overdue for a magnetic pole flip

I know a lot of the early approaches to power generation relied on DC power. That was one point of contention between Edison and Tesla.

Supposedly Edison pushed for the electric chair using AC to make it seem more dangerous.

I seem to remember reading something about electrocuting an elephant too.

My wife’s family is from a small town. For a traveling circus an elephant was standing up a pole and it got into the power lines. Killed the elephant and it’s trainer. They buried the elephant in the back of the parking lot.

Old movie where Edison electrocuted an elephant

I don’t know about the electric chair, but I believe Edison was all in for DC, Tesla was all about AC. Of course, Edison sucked eggs on that one.

I could be wrong but I was under the impression it was the other way around. But I don’t recall.

Right, Westinghouse, not Tesla. What I actually remembered was Edison was all in for DC. Clearly I didn’t recall who was for AC. blush

Ahh… it was Westinghouse, not Tesla. Thanks @mota!

Even being wrong: it’s pretty amazing we’ve only had electricity for 150 years.
