You can’t refuel a gas car without electricity anyway, the pumps are electric.

I wonder if densified wood would be better.

I hate corpo speak so fucking much.

Ummm… 10 knots * 200 = 2000 knots. I don’t think so lol.

First of all, kinetic energy scales with the square of an objects velocity.

Second, since we’re talking about a continuous stream of fluid instead of a single object, increasing the air speed not only increases the enegy per unit mass of air, but also the number of units of air per second that pass through the turbine. Which means that the amount of energy extracted scales by the cube of the wind speed.

So, more like going from 10 knots to 60.

It would be a matter of what kind of video it is and what situation I’m in.

Generally I watch almost everything on my desktop PC, but if I’m away from my computer and I also have to sit and wait for a few hours I might watch something insubstantial (not a movie or something) on my phone using an earbud. That is if I’m not using my phone to read instead.

I fell out of love with Team Fortress 2 after they murdered the art style with the cosmetics and extra weapons.

I didn’t realize it at the time but later on I fell further out of love with it for its role in normalizing lootboxes. In retrospect we should have shut that shit down as hard as horse armor was. Tribes: Ascend and TF2 were patient 0 and 1 in the pandemic. It was seen as acceptable at the time since the games were free, but we didn’t anticipate the broader effects it would have.

Late 19th/Early 20th century had about 1/3rd of all cars on the road be electric.

Long before lithium batteries were ever a thing.

You want to tell me what the top speed and range of those cars were?

Also, Theres a much higher demand thanks to the modern resurgence of electric cars, for better, cheaper batteries.

I think you’ll find that the first modern resurgence in EV interest came in the 1970s, with the 1973 oil crisis.

If you research the history of battery technology I think you’ll also find that it hasn’t been static since 1900 with lithium ion popping up out of nowhere in 2008. In between we had things like nickel metal hydride cells, and for a few years before Li-ion became practical there were even some EVs that came with the option of molten salt batteries (called “ZEBRA” batteries) for extra range. Those things needed to be heated to 572° F in order to function. Nobody would have done that if they could’ve just instantly pulled a better battery technology out of their ass like you seem to think they can. By the way, the name “ZEBRA” comes from “Zeolite Battery Research Africa”, the scientific project that invented them, which was started in 1985.

Just like computers have much increased demand for ram today than they did in the 1970s.

I promise you that people wanted more computer memory in the 1970s.

While we’re on the topic of computers though, do you know what the current state of the art is in chip fabrication? It is extreme ultraviolet photolithography, or EUV.

The first commercial product made with EUV was released in 2019 (the Samsung Galaxy Note 10) but the first EUV demonstration took place in 1986 at the Japan Society of Applied Physics. Originally they thought EUV would be ready by 2006, but it took an extra 13 years to develop.

Notably a number of other technologies, like contact lithography, electron beam projection, ion beam projection, and proximity x-ray were being developed simultaneously, in competition with EUV. EUV won out in the end but for a long time people were not sure which would be the most practical to implement.

So yes, the pop-sci articles written about stuff like this are stupid, but the idea that things are fake unless they can move from the lab to the factory floor within a year is just not how the world works.

Even if they could be used for something productive that’s impossible now because of their extreme over-use and abuse.

Research into the lithium ion battery started in the 1970s and they only became common in EVs in the 2010s.

So yes, it would “take long” for companies to “jump on them”.

So, if it was like Signal and didn’t let you self host at all it would have ranked on this list?

Building the machines and running them are two different skillsets. Like building a race car vs driving one.

Its at least somewhat based on the transistor density increase they get from other techniques right? Like “3 nm” is the equivalent transistor size they’d need to get the same transistor density using 2005 chip design.

I had a very similar childhood in the US.

I sat at a booth and played with coloring books while my mom worked in a restaurant’s kitchen, dad’s work was seasonal and very irregular. We didn’t drink the tapwater in our little town because it didn’t smell right and even came out discolored a few times; instead we’d drive to springs where a bunch of other people got their water too.

Imagine going back in time to 2015 and showing this article to someone.

I don’t know much about photography, so forgive me if this is a dumb question, but would something like focus stacking help with this?

That is to say, make the lens less of a bottleneck so you could benefit from a higher resolution sensor.

It’s really not.

There are large chunks of it that are really repetitive and boring, just things like the number of goats and chickens owned by so and so.

And like a lot of ancient mythology it can be really hard to relate to, given the vastly different cultural context that produced the text. That can be kinda entertaining in it’s own way, but mostly it just means that you’re not really going to understand the character motivations or themes of a story. Also sometimes the protagonist will do something horrifically immoral by today’s standards without the text treating it as notable at all.

IMO all of the actually interesting parts (like Genesis) are all really short and you probably know them already from cultural osmosis.

Anyone interested in this concept should take a look at plan9. Everything is even more of a file there.

Taking a screenshot, for example, can be done with:

cat /dev/screen | topng > screenshot.png

That combined with the way that parent processes can alter their children’s view of the filesystem namespace allows for extremely elegant abstractions. For example, every program just tries to write directly to screen or audio, but the desktop environment redirects their writes to the relevant servers. Which means that, in the absence of those servers, those same programs can run just fine and don’t care whether they’re being multiplexed or not. That also means that the plan9 userspace can be nested inside itself just using the normal mechanisms of how the OS works (that is, without a special tool like Docker).

I see

In your opinion is there anything useful we can do with that part of the radio spectrum as those stations switch off, or are those frequencies going to be silent in the future? Will they be turned over to hobbyists maybe? (or would the power requirements be too high at those frequencies?)

Since the portable radio doesn’t have much power, you may need to use digital modes to get through.

I don’t know much about radio stuff, but ever since I learned about LoRA I’ve wondered what kind of range a station could get if the longwave or AM bands were repurposed for use with a spread spectrum digital protocol. And what kind of bandwidth something like that would have.

I think being able to do datacasting over really long ranges would be useful, so, for example, you could send emergency alerts to people even if the local cell infrastructure was down. But with the way things are headed I guess that role will be taken up by satellites.

Chemicals like sodium lauryl sulfate and other fatty acids with organosulfate head groups, which are much more powerful surfactants than the fatty acid sodium salts you get by reacting lye with a fat (like vegetable oil). “Traditional” soaps like that also contain glycerol (formed when the lye cleaves the glycerol backbone off of a triglyceride), which acts as a humectant moisturizer.

Technically, at least in the US, chemicals like SLS aren’t legally classified as soap, and must be called a detergent. Which is why so many products are called things like “body wash” and “body bar”, and you wont find the word “soap” on their packaging.
