There’s a manual release that can be used to open the hood from the outside even if the vehicle has no power.
It’s a safety feature for first responders, as also under the hood is a loop of wire that can be cut to permanently disable the high voltage curcuts prior cutting open the car with saws.
There is a manual door release that works without power, but only from the inside. She had just loaded the child in their car seat, shut the door then went to the driver door to get in and couldn’t open it.
The doors are on the 12V side of the system, you can use jumper cables to connect an external battery from another vehicle (including ICE vehicles) to power the door under normal circumstances. But with a kid trapped in the car in AZ, I wouldn’t wait for that either.
It a pretty rare combinations of circumstances, but there’s something to be said for manual keys still used on other vehicles with keyless entry.
Most large corporations’ tech leaders don’t actually have any idea how tech works. They are being told that if they don’t have an AI plan their company will be obsoleted by their competitors that do; often by AI “experts” that also don’t have the slightest understanding of how LLMs actually work. And without that understanding companies are rushing to use AI to solve problems that AI can’t solve.
AI is not smart, it’s not magic, it can’t “think”, it can’t “reason” (despite what Open AI marketing claims) it’s just math that measures how well something fits the pattern of the examples it was trained on. Generative AIs like ChatGPT work by simply considering every possible word that could come next and ranking them by which one best matches the pattern.
If the input doesn’t resemble a pattern it was trained on, the best ranked response might be complete nonsense. ChatGPT was trained on enough examples that for anything you ask it there was probably something similar in its training dataset so it seems smarter than it is, but at the end of the day, it’s still just pattern matching.
If a company’s AI strategy is based on the assumption that AI can do what its marketing claims. We’re going to keep seeing these kinds of humorous failures.
AI (for now at least) can’t replace a human in any role that requires any degree of cognitive thinking skills… Of course we might be surprised at how few jobs actually require cognitive thinking skills. Given the current AI hypewagon, apparently CTO is one of those jobs that doesn’t require cognitive thinking skills.
I respect you for doing your own research. People need to understand the scope of the problem if there’s going to be meaningful action.
The reason I’m passionate about nuclear in particular is that only about a quarter of all fossil fuel consumption is from electricity generation.
Most of the rest is burned in transportation, buildings, commercial and residential applications. We have the tech already to switch most of these things to electricity, and eliminate their direct emissions, but that’s not much of a win if we’re burning fossil fuels generate that electricity. Which is what happens today when electricity demand is increased, we can’t just turn up the output of a solar/wind farm in periods of high demand, but we can burn more natural gas.
Switching to electric everything (Car, trucks, ships, heat pumps, furnaces, etc) will increase electricity demand by 2-3x.
Even if renewables growth is held to the exponential-ish curve it’s been so far (doubtful) we still need 15+ years just to get to the point of replacing current global fossil fuel electricity production in the most optimistic case, never mind enough to handle 2-3x demand.
Massive quantities of new carbon free electricity generation is needed to “unlock” the electrification technologies we need to deploy if we going to avoid the worst of the disaster. If we wait until renewables alone get us there it’ll be too late.
The more carbon free energy we can build in the next 20-30 years, the more options we have. Even if we can reach a place of excess capacity, there are a lot of things like DAC and CCS, that we could use it for that today result in more emissions from electricity generation than they sequester.
I don’t know, but it’s bad.
At this point even our best case scenarios are still pretty bad; barring some massive breakthrough in carbon sequestration tech.
And the “business as usual” scenarios are down right scary, millions of deaths annually. Never mind the economic consequences.
In my other comment I talked about what needs to happen on the macro level.
But the micro level is another story.
I’m worried because the paths to mitigating the worst of it depend mostly on countries, people, corporations etc… making major changes to drive reductions.
I seen the strategies the big companies have… they’re not coming close to making the difference needed. And the small companies aren’t even trying to measure their emissions let alone reducing them. It’s that lack of data that’s a part the problem. The data needed for decisions at the micro level isn’t available. It’s difficult to even identify what changes to make because you don’t know what impact a change might have outside of your control.
So far it means we haven’t even got emissions to start going down. At best, they’ve just slowed the rate at which they’re going up.
Governments should be pushing harder to mandate emissions reporting, but it’s politically unpopular so we’re still largely guessing about what decisions to make and that’s what leads to us all pulling in different directions making little progress.
Thanks, this made me laugh, hard.😊
(Sorry for the length here… this is actually my shortened version)
89% of climate change is because we took carbon that was permanently sequestered underground in the form of oil, gas, and coal and burned it for cheap energy. We need to stop that entirely but you can’t “just stop oil”, you need to remove the demand not try to disrupt the supply.
There are 4 broad strokes to making that happen:
Renewables are great and we need to build as much as we possibly can, but what people don’t get is the sheer quantity needed. No matter how much money is thrown at new renewables projects we simply can’t build enough of them fast enough due to bottlenecks in supply chains, raw material mining, grid interconnection times, and other limits.
New nuclear is the only other major option to speed up the transition away from fossil fuels. People resist it because of safety or waste concerns (neither are backed by data, nuclear is tied with solar for the safest tech, and it generates less radioactive waste than coal). Or they think nuclear has a big carbon footprint when you include the manufacturing and disposal (also not what the data says, nuclear is tied with wind for the lowest full lifecycle carbon emissions and is about half as much as solar). Or they argue renewables are cheaper which is at least mostly true, but it isn’t as clear cut either when you factor in the costs of connecting that many renewable power projects to the grid. Connecting one nuclear power plant to the grid is significantly cheaper than connecting the 100+ wind and solar farms needed for the same quantity of electricity. Not to mention the cost of storage.
We want to be building renewables, but we can’t wait around for renewables to save us that’s just not going to happen fast enough, our best option is building as many renewables as possible and a bunch of new nuclear and anything else carbon free at the same time.
But deciding what to electrify, when and in what order is complicated too…. adding to electricity demand before we’ve removed fossil fuel power generation from the grid, results in the scale-up of the fossil fuel generation to meet the increased demand. Until fossil fuels are gone from the electric grid, we should only electrify something if its efficiency is sufficient to still reduce emissions when we assume it’s powered by the most polluting form of electricity generation on the grid.
Battery electric vehicles have reached that point including factoring in the high-carbon footprint of lithium-ion manufacturing. Even if charged exclusively with coal power a BEV has lower lifetime emissions than an ICE car. Even discarding ICE cars before their end of life to replace with a BEV will generally be a net win.
Hydrogen fuel cell vehicles on the other hand (pretty much anything hydrogen-powered for that matter) aren’t even close. Using Hydrogen to power vehicles is not a tech we should be investing in right now.
Even if you’ve built a dedicated solar or wind farm to power something you want to electrify that hasn’t reached that efficiency threshold, you need to ask if it’s better to use that solar farm to displace current coal or natural gas-based electricity generation than to power your newly electrified whatever. This is why even so-called “green hydrogen” is a counter-productive tech to be investing in right now.
It’s also why some DAC and CCS techs shouldn’t be built yet. Even if you plan to build a dedicated solar or wind farm to power it. It’s often more impactful to just connect that solar/wind farm to the grid instead to reduce fossil fuel-based generation than to use it to power CCS. DAC and CCS is a rapidly developing space, we’re all hoping for some new breakthrough techs here that changes this story… so don’t criticize research in this area as a dead end… we don’t know that.
Hopefully, you’re starting to understand why so many of these discussions are more nuanced than people on Reddit/Lemmy claim…. a lot of new electrification technologies are just on the borderline here for not causing more emissions, and it often depends on where you live and what will be scaled up to meet the added electric demand.
All of this points back to why we need massive quantities of carbon-free electricity. Without clean electricity, these other techs aren’t a net win. Many things will cause a net increase in emissions if they’re electrified before carbon-free electricity is abundant. We need more new carbon-free electricity generation built in the next two decades than all the fossil fuel generation we’ve built in the last century put together. Even with ridiculously optimistic exponential growth projections of renewables, it is just not going to be enough. Until we’ve sequestered so much carbon that we’re back to pre-industrial levels, there will always be new techs that are “unlocked” by any additional carbon-free electricity generation.
Capitilizim’s tendency to push towards ever more consumption is the largest driver of the problem here. We can’t have circular economies if the only metric we’re looking at is the bottom line. Our modern mentalities of disposable products, planned obsolescence, fast fashion, and other things we’ve come to associate with a “high quality of life” in wealthy nations need to be re-evaluated.
The EU is starting to mandate carbon reporting, but the US and Canada are lagging in this area. The US SEC proposed last year making reporting mandatory for publicly traded companies but caved to a bunch of pushback from corporations. They did pass a mandatory reporting rule a couple of months ago, but with significant retractions on what needs to be reported and how soon. They dropped a provision that would have required companies to report on emissions they’re causing to occur in their supply chains (known as “Scope 3” emissions), which would have put significant pressure on smaller and non-publicly traded companies to also report on emissions.
Until the vast majority of corporations are tracking emissions, even the corporations that are trying to reduce emissions are limited in effectiveness because they are basing decisions only on how it impacts them directly and not what impact it might have elsewhere.
Anyhow… that’s the “big things”….
There are a lot of interesting little things that could be happening but aren’t, usually because they clash with a particular political ideology. For example, the government could pay contractors to go from house to house and upgrade the insulation, and it would have one of the best emission reductions for the dollar than almost anything we’ve quantified. But politically there’s a “It’s not fair to take money from my pocket to pay for someone else’s insulation” mentality that some people have that prevent many low-hanging fruit things…
And on the flip side, some of the things that we’re doing that generally aren’t working include:
Most carbon offsets on the market are bullshit, including a lot of nature-based offsets. The mentality of “don’t reduce just offset” emissions doesn’t work. I’m not saying there isn’t a place for offsets, there is, but the carbon offset market in general is full of bad actors. It’s trivially easy to misrepresent creative accounting as a carbon offset, even if it’s not intentional. And since there’s no tangible product delivered, some companies will sell the same carbon offset to multiple buyers. If you don’t believe me, I have a bridge carbon offsets to sell you.
Another thing that isn’t working is most (if not all) RECs, GOs and similar market-based instruments for purchasing “green electricity” from the grid. You’re not changing the net emissions, you are literally just paying for the privilege of claiming your electricity consumption isn’t generating emissions. You’re not making more renewable get built, renewables are already cost-effective, they don’t need someone voluntarily paying extra for them for them to happen. If you pay extra for them, you’re just increasing someone’s profits.
Note that RECs and GOs are not the same things as private PPAs, like when Amazon or Microsoft pay to build new nuclear to power their data centres. Again lots of nuances here, but PPAs are causing additional carbon-free electricity to be built. RECs and GOs where you’re selling renewables that have already been built aren’t changing anything, just upping profit margins.
LOL, I work in climate science.
Specifically in consequential carbon accounting analysis. Which is the branch that specializes in quantifying how much impact decisions and policies will have on greenhouse gas levels.
We are fucked. We are so incredibly fucked.
I comment regularly on social media about what actually needs to happen if we’re to limit the damage from WW3 to just seriously fucked. You can imagine how that goes.
People advocate for things on Reddit or Lemmy about what we should be doing to avoid the disaster. Most of the time these things will have little benefit, and often will make things worse. I try to educate people but everybody has their pet issues usually based on whatever article they read last and they don’t actually want to seek the truth, just defend their opinion.
It’s tough because they are all very nuanced issues, every decision has trade offs, makes things better in one way worse than another. People aren’t wrong about the small part they’re looking at, just its impact on the bigger picture.
Everyone is pulling in different directions on this issue because the waters have been so incredibly muddied by the people who stand to lose from real climate action.
Don’t take my word for it. Look up the numbers for yourself and do the math.
Search for “National GHG inventory {your country}”.
You find a report listing (among a bunch of other things) the amount of electricity generated each year by each method, and the emissions from each. Look up the total TWh of electricity produced by fossil fuels.
Then look at the total TWh from renewables, and rate it has been growing Y-o-Y and extrapolate until it reaches the number needed to eliminate fossil fuels.
You’ll find it will take decades to build enough renewable capacity to replace fossil fuel based electricity generation.
And that’s before you realize that only about 25% of fossil fuel combustion goes to electricity generation. As we start switching cars, homes, industries to electric we’re going to need 2x-3x more electricity generation.
Yes it takes a long time to bring on a new nuclear plant, roughly 7-9 years. If it was remotely realistic that we could build enough renewable power generation in that time to replace all fossil fuel generation then I’d agree we don’t need nuclear. But we’re not anywhere close to that.
It’s also helpful to note too just how much power a nuclear reactor generates. I live in Canada, our second smallest nuclear power plant in Pickering, generates almost 5 times more electricity annually than all of Canada’s solar farms combined. It will take 1000s or solar and wind farms covering and area larger than all of our major cities combined to replace fossil fuels…
…or about 7 nuclear power stations the same size as Pickering.
Yes and no. Renewables are now cheaper than other forms of energy but cost isn’t the only issue.
There are practical limits on how many renewables projects we can build and integrate at a time. We’re not even remotely close to building them fast enough to save anything. We can’t even build them fast enough to keep up with the ever increasing demand energy.
Nuclear is expensive as fuck but we need to be building more of it as well as renewables because we can’t build enough renewables fast enough to avert the catastrophe, and that’s about the only other tech we have that can generate energy in the massive quantities needed without significant greenhouse gas emissions.
And it’s never going to change either. No politician would ever campaign on a platform of prison reform, few would even vote in favor of it. Imagine the attack ads “Jeff Jackson wants to let murders and rapists go free and work at your kid’s school. Jack Jefferson protects kids and is tough on criminals voting three time to ensure growth of his investments in PrisonMegaCorp make sure they rot in prison forever… I’m Jack Jefferson and I approve this message.”
Genuinely curious where do you draw the line?
Like honest question: Do you think we should ban every activity that is as risky as consuming marijuana? If not, why not? Why marijuana and not everything else.
If we’re banning marijuana to save lives because it’s too risky we should be banning driving a car, and climbing a ladder, and hundred other common everyday activities that are more likely to kill you then smoking pot.
You’re not wrong, there are health risks to weed. But there’s risks with literally everything, and weed is really far down on the list of most risky activities.
We’re both correct.
LCOE is based on total operating costs of new electric power generation station over a 20+ year operation life. There are obviously a lot of assumptions in these sorts of analyses but Nat Gas is projected to become cheaper than Coal over the life of a new project, which some of that is expected to be due to carbon taxes.
LCOE has some flaws as a comparable number when comparing wind and solar to fossil fuels, but is good for understanding what will be cheapest to build of fuel based generation.
For current existing power stations, coal is cheapest of the fuels. The EIA numbers are here and here’s Statista research here on the historical cost of nat gas vs coal specifically which is frustratingly why coal phase outs have been so slow. Keeping existing coal plants operating is cheaper than building new almost anything.
And you are correct, price is specific to geography and availability of each. My blanket statement of “coal being the cheapest fuel” is over generalized and not universally correct.
It’s expensive and dirty fuel.
It’s definitely the dirtiest fuel by a good margin. But coal is actually the cheapest fuel. Which is the main reason it still gets used.
Uranium used to be cheaper than coal, but now that we all but stopped building nuclear power plants it’s gone up significantly.
Wind and solar are now cheaper than coal for electricity generation, if we can limit growth in energy demand to a rate lower than the growth in renewables, economics will eventually push all electricity generation off of coal.
I think you may have misunderstood friend. You’re not wrong and I’m not arguing against any of your points.
A wind or solar farm is indeed much faster and cheaper to build than a nuclear power plant. Wind and solar farms take 8-18 months on average. Recent nuclear power plants have been taking 7-10 years.
The nuance isn’t the time required for a single project, it’s the sheer number of renewable projects required that is the issue.
I live in Canada, a single digit number of nuclear power plants here could replace all of the fossil fuel based electricity generation in our grid. That’s something that could be built within 10 years.
We’d need ~1000 new wind and solar farms (not to mention storage) to do the same. We can’t make that happen within 10 years due to supply chain and grid interconnection bottlenecks limiting the number of concurrent projects we can do.
I would ecstatically overjoyed to be proven wrong about this. But we need to get off fossil fuels as quickly as possible, and we can’t do that quickly with renewables alone.
Frankly we’re fucked either way, but we’re less fucked if we build nuclear power in addition to as much renewable power as we possibly can make happen.
You’re correct about renewables being cheaper… but faster is a more nuanced discussion.
In the Canadian province I live in we generate 70% of our electricity with natural gas fired power plants. Roughly 20 TWh annually.
To replace that 20 TWh/yr with solar power, we’d need to build ~150 more solar farms the same size as the largest solar farm in Canada. Plus enough storage to cover the grid at night or when the weather is cloudy.
To replace that with nuclear power, we’d need 2 plants the same size as the smallest nuclear power plant in Ontario.
The nuclear plants are significantly more expensive than the solar, that much is certain.
But there are logistical limitations on how many new sources we can interconnect on the power grid in a given year. We simply can’t connect that much new renewables quickly.
It doesn’t need to be a choice, we can do both renewables and nuclear. But if we want to get off of fossil fuels in the next decade, nuclear will get us there sooner.
I thought the Quran made no mention of FGM, and that the practice was discouraged (or outright forbidden) by Islamic fatwas / religious scholars.
I totally do. Have since I was a child.
As a kid I would sorta step into pants so they were on my feet, jump and then pull them all the way up in mid air.
Now I just sit on the edge of the bed, pull pants up far enough that my feet through then stand up and pull them over my butt.
Never really understood the expression about how we all put our pants on one leg at a time.
I question the methodology here. The same site lists Linux desktop share at 2% in my country specifically. It feels like if it was that high you’d see it on people’s laptops more in coffee shops and what not… but I’ve yet to see a single other person using Linux on the desktop.
I know most of that 4% is in India… but still feels like it should be more ubiquitous if the number is that high.
Sandford Fleming (the guy who invented time zones) actually made it easier.
Before timezones, every town had their own clock that defined the time for their town and was loosely set such that “noon is when the sun is at its highest point in the sky.” Which couldn’t be measured all that accurately.
If it wasn’t for Fleming, we’d be dealing with every city or town having a separate time zone.
