A unique sound alleviates motion sickness

Retirees increasingly don't want to live in the empty desert. They want to live in the convenient and familiar places. Except that's where everyone else wants to live too, but since the retirees have the money, the existing land, and the voting power, they're blocking everyone out.

True that many seniors are aging in place and occupying more housing than they need.

You may have a sensor that estimates CO2 based on measured total volatile organic components. These are called eCO2 sensors, and were used instead of the gold standard NDIR sensors due to cost.

There are better cheap sensors available now, like the one in the $30 IKEA Alpstuga: https://cleanair.community/t/thoughts-on-the-ikea-alpstuga-a...


I've got an Aranet4 and started tracking CO2 and submitting it to IndoorCO2Map (via https://whn.global/indoor-co2-map-co2-monitoring-and-data-co...), but after a short period of time, there aren't really any surprises. Carrying a CO2 detector everywhere seems like mostly a way to give yourself anxiety.

If it's crowded now, or was recently, the CO2 is going to be high. If the building is old, or low volume, the effect will be worse.


Aren’t old buildings usually draftier? So less CO2

I've found old buildings to have generally worse air quality than newer buildings because of a lack of mechanical ventilation.

How can it detect nearby microphones?

Also, seems like your voice would easily project farther than 2 meters, the "protection zone" of this device. That's not even the size of a room.


School-type long essays only seem to exist in academia. I took a "business communication" class in college and we didn't write essays. My life experience since then has supported the "no essays" conclusion.

A long comment online now means either two things: it's written by a crank who has strong opinions, usually only tangentially related; or someone who has deep knowledge about the subject and has a lot of detail to provide. It's usually the former.


I agree with you on how their quality is spread out. But, this...

"School-type long essays only seem to exist in academia."

Does an AI know what an essay is? Would it consider any long, descriptive post an essay? Especially if pretraining data has many people describing long posts as essays or "essay-like?" Or only actual essays? And what is an actual essay again?

I think AI's might have different interpretations due to the above questions. They might also conflate essays with longer, detailed, or argumentative posts. We'd have to put a bunch of posts into a bunch of AI's to ask how they classify them.


That technology is way too new and unproven.

I'm thinking more like a hole-punch front facing camera, or an "invisible dynamic island".


Have you all actually read the article?

"In the U.S., it has been estimated that the foldable iPhone may start at or above $1,999"

Awesome.


I typed in my graphics card (1060) and it wasn't even in the list, so this tool actually proves that I need a GPU upgrade.

Touché! You got me here bro :-)

People would be unhappy with a charger that only worked slowly and during the day, even if it was free.

Why would I be unhappy? Consider this:

I drive to the mall.

I plug in the slow free charger (maybe ~3500W) as opposed to the paid one at >20000W.

Two hours later I have, say, about 7kWh topped up on my battery.

I now have restored about 40km range, so my 30km drive to and from the mall would be entirely restored.


A non-grid tied charger cannot be depended on. You might get 40km worth of charge. You might also get zero if it's cloudy or the sun is behind a building.

You might say, oh this is fine, anything is better than nothing. But someone cheaper than you will think the same thing, and they will leave their car plugged into the charger all day long, because the cost of free surpasses everything. And it means that the charger will never be available.


> You might say, oh this is fine, anything is better than nothing. But someone cheaper than you will think the same thing, and they will leave their car plugged into the charger all day long, because the cost of free surpasses everything. And it means that the charger will never be available.

Two things:

1. Parking itself doesn't have to be free, even if the energy was. (Though I don't expect the energy would ever be free in a case like this, because sending it out to the grid isn't that big a deal, and neither is micro-billing).

2. You seem to be imagining a single isolated parking space in a bigger parking area, whereas the article (if you can call it that, it's the size and depth of a tweet) is saying it is mandatory, at a quoted rate of:

  80 or more spaces must install solar power generation facilities with a capacity of at least 100 kilowatts
If this is to be a general requirement across all parking spaces, they don't get hogged, because there's always more parking.

Even better if we could somehow trunk my space’s 3500W of panels with the ones covering the combustion-driven car next to me. And the empty space to my other side…

You missed the most important part, in which you pay for all this (directly or indirectly).

As opposed me paying indirectly and directly for all the subsidies for the petroleum industry?

> Global explicit subsidies for fossil fuels amounted to around $1.5 trillion in 2022. […] The $7 trillion figure includes the social and environmental costs of fossil fuels.

https://ourworldindata.org/how-much-subsidies-fossil-fuels


The article you linked literally talks about fuel subsidies in the UK aimed at reducing the final cost of electricity for households and its vulnerability to rising of fissile fuel prices.

In the UK. A country that was one of the first to transition to renewable energy sources and which currently has one of the most expensive electricity prices. And then, to these "subsidies", losses from "road incidents" are added as other subsidies for fossil fuels.

Sorry, this is very difficult to perceive as an argument, it is literally designed for degenerates without education, who have difficulty understanding the meaning of words put together in sentences, and who, for this reason, evaluate any text by the presence of already familiar slogans in it


Why do you think anybody was operating under the assumption that this was free? But keeping your car topped up now is hardly free either, especially lately, so the question is really about cost comparison. And that's before you get into any externality costs.

> so the question is really about cost comparison

Yes, and I was talking specifically about the cost of this difference.


They'd also be unhappy with a solar panel that only generated power when a car was plugged in. Fortunately it would still be connected to the grid, resolving both concerns.

I'm not sure that's true?

Your car already has the battery built right into it, so a trickle charge for eight hours while you're busy at work might be enough to cover your commute.

2 kW over 8 hours would be enough for 100 km per day.


Why? The vast majority of cars spend most of the day stationary. I'd even venture to say most cars spend most of the day stationary in the same spot. If that spot has charging, slow or not, it would likely cover the daily energy used by that vehicle. Aside from road trips, that literally sounds like the perfect charging setup to cover most vehicle use-cases.

I drive to work, I park in the parking lot, 8 hours later I leave work. My car is now fully charged.

I would be utterly devastated.


It's not reliable if it's not grid tied. Your car might be fully charged. It also might not get any charge at all.

Going up thread a bit, I find "and have a fairly small connection to the grid."

Though even without that, so what? The typical commute is not half a battery's worth of kilometres.

And even for the exceptions, you're allowed to have a split between parking spaces labelled "this juice is completely free but slow at the best of times and depends on the weather" and others labelled "this juice costs ¥¥¥/kWh but is backed by that hydro plant and will fill your batteries in 30 minutes".

I mean, parking spaces already get a split between long stay and short stay, it's not like people can't handle ideas like "free and meh vs. pricy and oooh", and likewise with fuel prices: https://www.istockphoto.com/de/foto/zapfsäule-in-usa-zeigt-p...


I would take the gamble somewhere there are 220+ days of sunshine per year, happy to pay occasionally and commute for free the rest of the time.

If anything all the panels can be connected together and charge the bosses cars up first and if there is any daylight left the charging can trickle down the org chart to the masses.


When has the US not been in a housing crisis? Might be 20 years now.
