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.
2·2 months agoVery 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.
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.
But remember, electric motors also require next to no maintenance and can last for many years of runtime. Pros and cons.
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.
Well, I just said carbon fiber, but to be more exact it is forged carbon SMC, so yeah, careful engineering involved. Same stuff Lamborghini is using for some structural components, so probably fairly fit to purpose.
Well, it has a carbon fiber frame with a crumple zone in the front. They are going to put it through 3rd party safety testing. It won’t be as safe as a big SUV, sure, but I think it will be safer than an ebike. It also protects you from weather and has 35 cubic feet of storage in the back. I think ebikes are great too, but this does have more of the advantages of a car.
The benefits increase as the efficiency of the car increases though, check out Aptera. They say they get 10 miles per kwh, and they have a lot of surface area for panels. Enough that in ideal conditions they say they get 40 miles per day from solar. It is a bit different looking though.
Growing crops to make ethanol is not particulatly green. In fact, in most existing production loops we would be better off environmentally to just burn pure gasoline than produce the ethanol to mix into it, unfortunately. Too much water, too many tractors and trucks, and way too much electricity into ethanol production to be worth what we get out of it. And the bit of carbon the crops sequester doesn’t overcome it. Electric vehicles are by far the greenest option right now.
Huh, I’ve been using a VPN for under a year, and DDG for just a couple of months, but I haven’t had a captcha from them yet.
If you are using Firefox, switch your default search engine to DuckDuckGo, haven’t gotten a captcha from them once. And right in the search bar you can switch to Google if DDG isn’t doing too well on a particular search, I do end up doing that about 5% of the time.
It won’t have started getting closer again before the Milky Way collides with the Adromeda galaxy in 5 Billion years, so it and anything we send on a similar path isn’t coming back.
I always saw it as being part of messing with the kids, he looks at the warning lights on top of the fence first. And for my headcannon at least, Grant is savvy enough to know that’s no way to test if the fence is live or not, lol.
