And it costs municipalities less money than the problems it prevents, so obviously we shouldn’t do this everywhere and raise the standard of living for everybody. Because it wouldn’t be fair, somehow.

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.

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.

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.

Exclusive: Tesla scraps low-cost car plans amid fierce Chinese EV competition (www.reuters.com)

The decision represents an abandonment of a longstanding goal that Tesla chief Elon Musk has often characterized as its primary mission: affordable electric cars for the masses. His first “master plan”, opens new tab for the company in 2006 called for manufacturing luxury models first, then using the profits to finance a...

Last year their revenue from selling cars, powerwalls, and solar tiles was around $90 million. Makes the stock price seem crazy, yes. But then they sold $1.8 billion of carbon credits to other auto manufacturers, and that costs them basically nothing. Still doesn’t justify the stock price, but makes it less ridiculous. Selling carbon credits is Tesla’s main business at this point, the things they make just provide the justification for it.

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.

jmiller ,

Oh, it’s not the only reason, and the other may actually be worse. They sold $1.8 billion of carbon credits to other auto manufacturers last year. Which is pretty much free money to them. And hastens climate change, but, you know, free money.

I’d say anyone choosing to drive 74mph in a 25mph zone can be said to have disregarded safety. And if you haven’t realized you are going 74mph in a 25mph zone, you shouldn’t have a license, let alone be an officer.

GMG’s Graphene Aluminium-Ion Battery Update: Minimal Temperature Rise Identified While Fast Charging (graphenemg.com)

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...

jmiller OP ,

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.

jmiller OP ,

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.

They are too expensive. But only because auto manufacturers are only making midsized and larger suvs or luxury cars. The average price of an EV has dropped over 50% in China since 2015. That would have been tough for us to match, mostly because of batteries, but we could have made much more progress than we have.

The electric grid isn’t nearly as unprepared as people say. Sure, we need to build out more charging stations, but the grid as a whole far exceeds current needs. In fact, nationwide electrical usage is actually trending down in the US because of efficiency gains. Better building codes, heat pumps, LED lighting, if it uses electricity newer stuff is more efficient. If we had sold 8 times as many EVs in 2023 than we did, electricity usage would have stayed about flat.

A increasing percentage of new construction gets heat pumps. Some replacement HVAC units make the switch, but there is still a large portion of people who won’t because of misinformation and/or stubbornness.

But, unfortunately, most existing residential systems do not use heat pumps, under 20% in the US I believe.

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.

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.

Well, as far as crash safety, I would think it would almost always safer to be facing backwards. That’s the way infant car seats are. Facing backward would mean your whole body would absorb the inertia change against the seat and your head would be supported. Better than seat belt bruises and a bobble head imitation, seems like.

That’s assuming the forward facing people in the back row are buckled of course. 60 mph headbutt would be…bad. Turn those seats around too maybe?

Nissan Sakura and Mitsubishi eK X EV are $14-16k, but are only for sale in Japan. Nissan closed orders for the Sakura because they already had more orders than capacity to make them. We need vehicles like that everywhere! That would drive EV adoption far, far more than another “affordable” $45k SUV.

jmiller ,

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.
