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.

But remember, electric motors also require next to no maintenance and can last for many years of runtime. Pros and cons.

Probably worse for Barbra than the picture is this phenomenon being named after her. I was familiar with the the Streisand Effect and who the name came from, but didn’t know the backstory and hadn’t seen her house.

For anyone curious.

Maybe that was literally the case, he apparently had mercury poisoning at around the same time.

It’s starting to sound like a retelling of the old lady who swallowed the fly.

Someone needs to invite /u/Poem_for_your_sprog to Lemmy.

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.

This is misleading, billionaires have been paying effectively lower taxes for many many years. They just had to be more creative about it before 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.

In general I agree with you for sure, we have way too many. But if there are any worth preserving, I’d say it’s the old ones in Scotland where golf was invented. And at least there they don’t have to be watered constantly.

I am not any kind of expert either, but I have been following this company for a couple of years. If it makes it to market and is at all price competitive i can’t see it not being a big deal. Granted, that is an if, not when, but they seem to be further along than most battery tech you read about.

No rare earth metals or even nickel or copper, has a very flat degradation curve even at charge rates up to 30C (testing stopped at 3k cycles in the coin cell tests), non flammable and non toxic. The only thing you would wish for is better capacity, but it is already better than any mass produced Li ion cell, and it has a theoretical maximum a couple times that of Li ions.
