Canada Taking it's money Seriously
I like that they've changed the standard orientation of the bill
I carry a 5$ Canadian bill that depicts kids playing hockey on a frozen pond and also has a poem on it
I wish the US could be more like CA
Testing the ice
I was taught to:
1) drill or chop holes close to shore first to check thickness
2) Carry a long pole/piece of wood (6 feet plus) so that if you fell, you wouldn't go under the ice (the idea of being swept under ice and not getting back to the hole you fell into...)
3) If going to rescue someone, tie off/get a line around yourself, and spread your body weight out by crawling/using a saucer/pan/kid's plastic sled...and offer them a line, pole, or thrown sleeve of a garment, not your hand.
anyway, looks like it was pond--they just lost some dignity.
Snow Day Fun...
My uncle had a very large frozen pond in winter, out back of his house. He used to shovel a skating area with 2-3 foot high berms of snow around it. Then he would hook up a tractor tire inner tube and tow us around with a snowmobile. It was the greatest day when we figured out how to put the tube on the other side of the berm and use the snowmobile to launch us off of the lip. We were thrown so high in the air we felt like we were flying, and only manages to land back on the tube about half the time. Didn't stop us from doing it for hours, despite the impacts.
The Way We Get Power Is About to Change Forever
There was a show, islands of the future, on Netflix now, that had a large scale demonstration and explanation of it, used to store wind energy and power an island.
Unfortunately, I don't know of a comparison with batteries with concrete numbers.
I think you hit the nail on the head with what you said about efficiency, but for large scale storage, it has to be better when you factor in the energy costs of making, replacing, and disposing batteries, even including the cost of replacing the turbines.
...and all that ignores the ecological issues, where ponds beat battery factories hands down.
Hadn't heard of that, but I get the concept. Cool idea.
Off the top of my head, I'm concerned about pump and generator efficiency. You're going to use some amount more energy to pump a volume of water up to the high basin than you will get back by gravity feeding it through generators. To be fair, efficiency is a problem with using and recharging chemical batteries as well, but the limited amount that I remember from college engineering courses tells me that efficiency in the electrical / solid state world tends to be more easily obtained than in the mechanical world.
And as another "to be fair", efficiency is a bigger concern for things like fossil fuels, where burning one unit of fuel produces a set amount of energy and you have to improve efficiency to get the most value out of that energy. With things like solar and wind being "free" energy when active but requiring storage for when the source is inactive (night / calm winds), efficiency still certainly matters, but not as much as with a scarce / non-renewable source of energy.
Anyway, I'd like to see concrete numbers comparing the utility and efficiency (in various metrics) of your hydro storage vs battery storage.
Pushy CNN Reporter Can't Take A Hint
I think it was right on the rails. I live in Houston, was fortunate to have come through Harvey with little damage, and spent hours helping folks get out of the small boats that were rescuing people from their water filled homes. The reporting from the various news agencies was on TV pretty much 24/7. But they don't get it... sure, people outside of the situation want to know what's going on, but some of the most inane, redundant, pointless and heartless questions in the world come out of the mouths of these reporters who feel they need to just keep on talking. On more than one occasion, we had to tell reporters to get the fuck out of the way so we could do our work instead of pausing to allow them to conduct an interview. In a situation like this, where people have lost EVERYTHING they own except for the clothes they have on, and have spent hours scared, cold and not knowing if anyone is coming to rescue them, how the fuck can anyone with an IQ bigger than their shoe size think it's a story that wants to be retold in front of a camera? We helped little kids out of boats, with their parents coming along a few boats behind, and reporters walking up to these shivering, scared kids to ask them about any pets they might have left behind or been unable to rescue - to get them to cry. That's inhuman. If it were me, I would've shoved that microphone down that stupid woman's throat. This isn't reporting, it sensationalizing. But I guess we wouldn't expect less from CNN. These people aren't reporters our journalists, they are pond scum.
How To Make A Blockbuster Movie Trailer
Can't wait for someone to apply this formula to slow, thoughtful movies like My Dinner with Andre, or On Golden Pond. (yes, I'm old, though I've only seen one of those examples)

He used an excavator and a bulldozer. Real men use their broken backs and a pick axe. ;-)
30 mil isn't 30 millimeters...his liner isn't over an inch thick...he wishes. I think mine is 45 mil. It's thick rubber.
Cool stuff. He has a different idea of what a pond is and what it's for than I do, but to each his own. He made a great place for the family...but they better learn pond safety...you could lose the whole family in that deep end and never see them.

When a Goose Loves a Human
Clearly fake. Everyone knows that geese are universally mean-spirited creatures whose primary interaction with other animals only include hissing and pinching with their beaks.
Seriously though, when I was a very young child my family had a couple of geese that were raised from little goslings. Those suckers would go after pretty much every other living thing that got anywhere near their pond. They'd chase and pinch our dogs, before the dogs learned to stay away from the pond.
They also once guzzled down a huge amount of old motor oil that got left out after an oil change. We figured they were goners, but I guess they just had extra-oily shit for a while, they never showed any ill effects from it.
