Tiles are great, I'd love to have a roof last 100 years. But they don't get as much use here because of issues with ice damning up the bottom edge and pooling water up under the tile, which then freezes and expands and dislodges or damags the tile. That can be overcome, but it's easier and cheaper to use shingles.

A fiberglass mat core with asphalt around it and grit stuck in the asphalt on the top.

And the person who found it isn't doing a good job either, putting new shingles over old. The old should be removed.

Very true. Unfortunately, this process just pulls gold from dilute sources and gathers it into nuggets, from small ones to very very large. No gold is being made new though, that would be great.

Well, that is the amount gold that is mined or recycled every year that is used in electronics. The thing is though, a lot of the gold used in electronics is never recovered. So a considerable amount of the gold used in electronics is removed from from circulation in a way the gold in jewelry or bullion or coins isn't. It isn't the primary driver of gold's price increase, but it is a significant factor.

Gold prices have risen steadily for a long time, partly because of its use in electronics. Over $2500/ounce now. But another quirk of gold is the ease with which we can make very thin coatings of it over other materials, sometimes only a few atoms thick. So it is commonly used, but in very very small amounts per device.

The first change needs to be teams pay for their own stadiums instead of them being taxpayer funded from cites and states. I don't care if it will drive tourism, use that money to take care of the purple in the city and make the city a nice place, even make it a nice place for a stadium, but make the team owners/pro leagues pay for their own damn stadium.

At some point it almost stops seeming like greed and more like the willful extinction of the human race. But I'm probably just underestimating the greed.

This isn't a science related meme. I can understand you not being sure where to put it, I haven't seen a "Racist Memes" community on Lemmy.

Sure he's got climate wins, but some of the wins are questionable, like giant hydrogen hubs. Hydrogen sounds great on the surface, but the more you dig into it, the more issues crop up. Some of these hubs will end up producing hydrogen by burning fossil fuels, and that isn't a win at all. And speaking of not winning, we are producing more oil and natural gas than ever before. That's why we aren't excited about his "Climate Wins", they are offset if not overcome by losses.

Having said that, regarding the Climate, pollution, and everything related, Trump is the worst choice. He's already promised Carte Blanche to oil execs if they donate to his campaign. (Not in those words of course, simpler, more incoherent ones.)

Sure, to get them to speak in unison. They did all read from the same script though. It wouldn't be as viscerally creepy without the editing, but I would say the situation is as bad as the video makes it seem.

 

Very interesting company. They started with a way to produce graphene at scale, then went looking for something to do with it. Their first idea was to use it as a cement additive. They have since used it as friction reducer in engine oil, and are selling it in Australia, Canada, and soon the US, as a radiator coating to improve HVAC performance.
