> Do you think you will know if someone has their phone in their pocket or in a holster, and is turned on and recording? You will never know.
At least this says something about the intention. Someone who films with a hidden phone implicitly shows that they intentionally hid this from the people being filmed.
Filming with glasses is hidden by design. It gives plausible deniability to the person filming, so they can film covertly but pretend they weren't hiding anything.
In most cases this doesn't make a difference but there are some cases where the premeditation can make it worse for the person doing the "abusive" filming.
> And then putting a battery next to it would have been even better then that.
An NPP doesn't benefit that much from a battery. They're generally used to provide base load which fits their constant supply profile. Peaks and quick variations can be supplied by more flexible renewables together with a battery to buffer it.
If your NPP output is lower than the base load (I think this is almost always the case) then the NPP will always feed all its constant production to the grid to satisfy the constant base load. If you have a battery and what to put it somewhere with the most impact, it should go next to the variable power supply, where it makes sense to store and supply later. That's what batteries do, store what you can't use now to supply it when you can't produce.
Look at this picture [0] of the German grid. Same for France [1]. Why would you store any of the nuclear output when all of it is guaranteed to be absorbed by the grid real time, day or night? You can, but it doesn't make economic sense. Batteries shine where they can smoothen peaks, like solar and wind.
The big reason to put batteries next to NPPs is the existing grid infrastructure. You can't supply GW-level power from just anywhere. It's like building a large warehouse next to a major transportation route.
There are lots of times and places where renewable production is higher than demand. When that's the case "the NPP will always feed all its constant production to the grid to satisfy the constant base load." increases costs.
“Increases costs” for who, the producer, the consumer, the distributor? If you have data on that I’d love to read about it.
I think the article mentions that recently batteries are always together with renewables. The reason this battery was built there has nothing to do with the NPP but with the proximity to the already developed power distribution infrastructure. You can assume they’ve all done the math when choosing to not build batteries next to working NPPs.
a npp benefits a lot from the batteries. Nuclear can be flexible and flexibility can be boosted with BESS buffers. Basically BESS would act similar to hydro in this case
> It seems there has been a complex balancing act which any owner of an old car will be familiar with: spend more money on keeping it operational, vs scrapping.
This is a different choice because the car analogy usually has "buy new one" as a term. Not having to build a new plant makes the choice far less controversial and also cheaper.
Obscurity is otherwise known as "trade secret". It's used when the company really doesn't want to give anyone even a hint of what and how it's doing things, maybe going as far as assuming nobody can figure out the process independently either, so filing for a patent is out of the question. The Coca Cola formulation is a famous example.
> someone to buy a bunch of stethoscopes and objectively test them. I would bet that there is a 10 USD model that is 98% as good as 200 USD models from 3M Littmann.
It's the same as every other field, cars, phones, or computer cases, you name it. Something can be artificially expensive, but it can also be because it uses better materials, has more features, is built to higher standards. And some things can't be tested properly in a small scale review. Longevity, for example.
But there are factors that influence the premium price. The build construction - quality of the construction, quality and feel of materials, flexibility/rigidity of components, comfort of the ear tips and why not, even color options or the logo that shows you don't cheap out on equipment. Functionality - amplification, frequency response, double sided, 2 diaphragms can be used on children and adults. And then you have nice features like tunable diaphragms, or warm rims/sleeves for making it more comfortable for the patient.
Like for any other product, you'll save on the things you don't care about. The neck is stiff, the earpiece is uncomfortable, the tubing degrades, it's ice-cold, not great for kids or thin patients, but the sounds come in loud and clear enough and it's half the price.
> Our 24 month can count to 20 and knows all the letters without watching TV.
I have a very qualified pediatric occupational therapist friend and when I was sort of bragging about how many "cool things" my toddler can do I was immediately told that they are nice party tricks but don't say much about the development of the child, predict future performance or intelligence, and definitely aren't what I should be focusing on as a parent.
The child didn't just naturally learn to do those tricks. Our games focused a lot on this because I thought "it builds brain and skills", always be ahead of all other kids. In reality only I benefited from this because I could drop it in random conversation and then have pride flow out my ears. And the kid kept repeating the now easy tricks looking for the reward, staying inside the comfort zone.
I was told to simply guide our interactions with a method called "serve and return"[0]. It's a much more powerful tool that makes any and every interaction an opportunity for development, not just individual tasks practiced to perfection and repeated for rewards. You guide but also let yourself be guided so your child gets to feel comfortable opening all kinds of doors rather than you even unwittingly pushing them through the same one again and again.
Thanks for the comment! I remember watching videos about this when he was younger. We actually didn't teach him numbers or the alphabet--he would point to signs on walks and say a letter then we would add another letter or two at the same time. So he just gradually learned them.
But I also am very much in the camp of "it doesn't matter what he knows right now. Kids advance in different ways at different times and it mostly just levels out" All you can do is amazed at how fast they grow and try to help them out as much as you can.
In most countries it's illegal to leave any child unattended in a way that puts them at risk which is a vague definition. But if something were to happen to the child while unsupervised any vagueness collapses into negligence. A baby will sleep in the pram, but for a toddler to be abandoned alone strapped in the pram is capital punishment.
> how can a child that can't even walk yet have the practice to know how to skip the ads
At 2 kids can walk and have fine enough motor skills to press a small button, if that was the direction you were thinking.
Kids are surprisingly intuitive and form connections super quickly. It probably took a few tries, and maybe the parent even showed them how to do it: button appeared in the corner > press it > see fun content. If something works they commit it to memory like you wouldn't imagine.
Kazakhstan is by far the largest uranium producer in the world and has a leg in Europe, west of the Ural river. The important thing is that there are more stable partners worldwide for uranium than Russia is for oil and gas.
There are deposits in Europe, the respective countries decided not to exploit them [0]. This could change depending on external pressures.
> The 1-MW chargers have internal batteries, so they can pull a much lower average power from the electrical grid.
We go back to what I was saying earlier [0], you'll need a lot of local storage to keep that charger running at full speed without breaking the back of the distribution grid. That comes on top of the solid grid capacity at every one of those many small parking lots.
One stall alone needs 1MW maybe equally split between the grid and the local battery, for probably 50-70kWh per car. Just 3-4 of these cars charging in a parking lot would mean a constant multi-MW pull from the grid on top of the battery that also needs to be recharged from somewhere. To guarantee that you lower that average you need to have enough local storage.
The technology exists, it works really well for large dedicated charging spots. The problem is the cost of scaling when you have to deal with lots of small plots (what OP proposed). A 1kW installation with 2-3kWh battery storage is the size of a small container and we've had them for years. Why do you think every small parking lot hasn't been equipped with one?
> requiring the electrical power suppliers to take into account this increased consumption
This doesn't scale like software. Adding production is comparatively easy, adding distribution capacity isn't. It needs a lot of equipment that's not really available [1], and a lot of construction work to expand the grid capacity.
