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.
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.
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.
Donkeys bray, scent hounds bay when they have a scent trail.

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.
You’re right, battery news IS always breathlessly excited about the next crazy advancement, but they have a lot of things in their favor on this one. They broke ground on a manufacturing plant last year, which is not the case for most battery news stories. And the battery uses no rare earth metals, is non flammable, and performes better by nearly every metric than lithium ion. If they make it to market, I think they will absolutely be revolutionary.
Well, you are right about the subsidies and going after bigger market shares. And they may not be the highest quality vehicles, but I don’t think they will be terrible either or they wouldn’t hold on to the market share they gain.
They have been making electric buses and forklifts in the US since 2009, and have a decent reputation.
EVs very rarely catch fire. A vehicle with a large tank of gasoline which is burned to produce power poses a much higher fire risk.
20-60x more likely to catch fire, depending on which study you look at. My first Google result said 20x, but it was on an EV focused website, and I thought they might not be impartial. But Kelly Blue Book should be pretty good, right? Their article says 60x.

This may be the most apt application of this meme I have ever seen, lol
I believe they are kei cars. I looked up the safety ratings on them when I heard about them, and the D.O.T. equivalent board that rated them gave them 5 stars. But it could be that was a kei car specific rating. It did show diagrams with front and side air bags, and all the electronic crash avoidance systems. It’s bigger and seems like it would be safer than a smart car. I honestly think the hold up is that if we had options like that in the US fewer bigger, more expensive, cars would be sold. Maybe not a lot fewer, but enough fewer that it is overall more profitable not to offer them.
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.
