Glass is 30% cheaper to make from recycled glass.

But transport and sorting (glass is hard and sharp) eat into that margin, so presort


> it takes as much energy if not more than just making new.

It saves 30% of the energy inputs to reuse slightly contaminated glass, especially when done locally.

That's ignoring the energy inputs of mining and delivering the silica.

It's more hardware intense, but yes, add an rfid tag to each key, use a btle obd dongle, centralize computing in an arduino; phone home to a webserver the last logs.

Then at the end of the month debit each account that used negative gas.

The only thing this misses is encouraging fill-up before empty, but it could give notice when the tank is below ¼ before a trip


This is definitely ¾ of what you pay a mechanic to do; 1 publisher writes a maintenance manual for a car; mechanics all around the globe can use that to work on that specific car.

It's the mechanics that don't reference Google or the Haynes manual that are more likely to get it incorrect.

As a kicker, mechanics also have a pricing book for the task, they know how many hours a task will take on a certain car (rounded up for the most part).


You are not responding faithfully to the comment. A mechanic looking up the schematics in a manual understands them. Just because they haven't memorized the material does not make it the same. This is more analogous to looking up a function in the documentation that you forgot about.

This is clearly not what the post was referring to, which is instead like googling how to fix a pipe in your home when you've never done any plumbing before in your life. Can it work out? Sure, depends on the issue, can you cause your pipes to freeze, your house to flood, or sediment build up to completely block a pipe? Yes.


> mechanics also have a pricing book for the task, they know how many hours a task will take on a certain car

I do want to point out that this is used to suppress mechanic salary. Certain jobs are absolutely fucked how its time calibrated. Doesn't matter to business owner they can charge $$$ how they want.


Your comparison reads to suggest that Japan doesn't have Onsen culture or that sauna does not exist in Norway.

That's to say, many cultures from around the globe have developed similar activities that heat the body.


40° internal body temperature is not the same as 40° weather.

Yucatan is not the same as Dubai in Summer.

Your body is under heat shock trying to keep up in a Sauna (that isn't considered warm until 60°). Versus a healthy body CAN keep up in 40°.

The Yucatan equivalent of a Sauna is more like doing hard labor on a roof on a sunny day with no breeze.


Right, it's just that a sauna at 60 degrees is not warm, it's cold. Take a shower, go into the sauna at 60 degrees C, and it'll feel cold. Nothing happens in a sauna until you're getting near 80, and it's much better if you go somewhat higher (90 or more for active users). 60 is when a sauna will be closed off in public baths because there's a technical problem somewhere.


And if Sadam did, then by proxy the US did.


I mean sure the US provided intelligence, financial assistance, conventional weapons, and the ingredients for chemical weapons to Saddam for this war, but the US was also the one selling Iran missiles in response to Saddam. Though admittedly we weren't doing this to help Iran, we just needed the money to help narco terrorists.


It's even worse when your goal is commercial viability of carrying a relatively flammable liquid.

Tankers moving at a slow speed, across a narrow strait.

They don't have to sink to not be commercially viable; a few deck fires negatively impact your days at sea without incident.


You and the poster above disagree about the state of Twitter.

Twitter had been a growth company, it was early/missed the market with Vine, but was showing ad growth.

Now, as a private company, backed by the world's richest man, sovreign wealth funds, and banks that have written down their stakes, it has different economics than a tech / growth company.

It's ad revenue is now, not in the ballpark of the fortune 500 or trendy Instagram ads, but somewhere between reddit and sin site markets.


The purpose of Twitter is IMO no longer to be profitable.

For a man with a trillion dollar fortune it’s just his personal equivalent of Fox News, a way to shape the nations conversation.

Plus a way to get data for xAI.

In that regard it’s a huge sucess. I use grok to find out about stuff on X and it’s very effective. Grok is also nowhere as bad as it should be (it’s still not great).


Most companies aren't that. Twitter is basically yellow journalism owned by a robber barron, just like in the 1880s.


Shape national conversations*, sure.

A way to get data for xAI? Eh, I guess. But it's a source of bad data. Most social media is, even the best case is stuff like Stack Overflow. It wouldn't surprise me if this was at least a strong component of why Grok called itself "Mecha Hitler".

Huge success? Unfortunately I have to agree, given the US government still ended up integrating it despite the Mecha Hitler incident.

> I use grok to find out about stuff on X and it’s very effective.

As with all of these things, I have to ask: How confident are you that it's telling you true things, rather than just true-sounding things? My expectation is Grok will be overtraining on benchmarks (even relative to the others, who will also be doing so at least a bit), and Grok's benchmarks will include twitter reactions, and it will be Goodhart's-law-ing itself in the process to maximally effective rhetoric rather than maximally effective (even by the standards of other LLMs) "truth-seeking".

* plural, not "the", it also works in at least the UK as well as the US


You can ask Grok for “find me this tweet on X, with direct links for sources” and it will do that. It’s basically a super charged fuzzy search engine for X which is great, since a lot of my searches are half remembered tweets that I’d like to find again.

So it’s accurate in the sense that it’s accurate finding things on X. I don’t really use it for anything else.


Thanks, that makes sense. I read too much into your previous comment and thought you were finding out more about things beyond twitter after they were discussed on twitter.


> Did the maker movement end? I dont think so

Bump.

Because we had our first high profile murder using a 3d printed weapon just last year.
