This is a problem *right now*. I graduated last year and some people passed a four year mechanical engineering degree without going into the shop *one time* and >3.8GPA. Students were often taught GD&T before being taught how to use a mill. Tuition was approx $60K a year. We need a skills based aptitude test at the end of the course. If you can’t use a hand drill you fail and can’t graduate for another year.

hello my name is dipshit propulsion engineer and today I'll be overengineering a BOX

@EndCulturalWar @x0_MeatSuit @FurkanGozukara What rates are you hearing for redwood? I get mixed reports. Making 95%+ battery grade at low rates is hard, and a great milestone, but high rates is very very difficult. Curious where they are on the rate aspect?

@x0_MeatSuit @FurkanGozukara With a recovery rate of 90%?

Massive geopolitical shift. NHK World confirms Japan has perfected a revolutionary process to extract high purity lithium from dead batteries with a staggering 90 percent recovery rate. This brilliant technological leap guarantees Japan's absolute economic security.

Interesting - I fully disagree with this take, let me explain why: - Limiting critical mineral sourcing to a single country as we have been is a fast way to become dependant. Dependance can be profitable in the short term, but as we are learning painfully now, it is incredibly risky. - We will need stunning amounts of lithium to keep up with battery and energy demand; this is an industry everyone needs to get their foot in the door on before it’s too late. This is a global race and the finish line is depressingly far away. - Lithium extraction is a great way to start being profitable in cell recycling before you get to some of the more exotic elements. - Good lithium extraction is a great way to showcase that you have a high purity materials stream to do further extraction on and showcases competence in executing chemical manufacturing scopes. It becomes much easier to approach people requesting for investment for extraction process expansion, or even making your own cells. - Recycled lithium is in many ways easier to refine than mined lithium. Contrary to other recycled products, recycled cell materials are often higher quality than those produced from new materials. In short, we needed vast quantities of lithium yesterday and demand is only going to grow. We need to diversify, we need to close the loop and lithium is a great stepping stone to more profitable steps. Question: I get mixed reports about redwood. How much battery grade lithium (95%+ purity, that’s where the big payables on that product stream are) are they producing per month?

A number of other operators have already achieved 90%+ lithium recovery at commercial scales. For example, Redwood Materials in the US have been regularly recovering over 95% of key critical minerals from end-of-life batteries for years. Don’t get me wrong, Japan’s advancement is welcome, but framing it as a ‘massive geopolitical shift’ or ‘absolute economic security’ is an overstatement.

These motherfuckers really do seem to see and solve every problem differently than everyone else. Really inspiring. Congrats Tesla.

Building a gigantic statue on the Moon would be much easier… No wind, very low gravity, no oxidation… We could bring hundreds of very thin metal panels, form them on the Moon, and assemble them around a very light structure.

@typesfast Also, planes spend too much time on the ground. They should be faster in the air and on the ground

How small is a transistor on a modern processors?

@ChinaUncensored This is a good illustration of why earth pressure balance Tunnel Boring Machines are such worthwhile projects. The lack of geological understanding is inexcusable though. Guy I worked with said a screw in a TBM he was driving failed and flooded the tunnel in under 7 minutes.

This is the Ningnan Tunnel, under construction at the Yanjiang Expressway in Sichuan. Sudden flood washes everything away. No word on the workers. Very little coverage inside China.

@cherniav I’m leaning towards it being true. I watched a lot of grads fail to ever apply knowledge in college, and then only land non-technical roles where they weren’t solving anything. It would be really easy to come out of roles like that and be unhirable 15 years later.

Seen on l*nked*n today. This is so insane this has to be bait Idk how people get by in mechE without deep knowledge of this stuff. everything is a spring or a cantilever beam

@bscholl @hidden_whale Are you including power, concrete pours and tooling in this estimate? $1M seems high for the plain unit, but with utilities and infrastructure that could be a very reasonable cost. Transformer upgrades for a machine shop can bite your wallet hard.

@hidden_whale This was done on a lathe that costs about $1m

People thought Boom would never be able to make our own engine. So we decided to up the ante and make our own engine *parts*. The first vertically-integrated part is now finished: a tie bolt for the high-pressure core machined of inconel 718, an ultra-hard nickel alloy

While @PalmerLuckey does not identify with the growing isolationist wing of the right, “I’m not that pro-interventionist.” “The United States cannot be in the position of sending our men and women abroad to die for other countries’ interests… We have to be the world’s gun store, and we need to be willing and able to provide everyone with the tools they need to defend themselves.”

@KennethCassel Not to mention the data they get from products you want, but that don’t exist yet. Today I would have been showing that AI that McM should sell a bearing with a 52mm housing to fit other SKUs, but with a 20mm ID rather than a 25mm ID because there are no 25mm clevis pins 😂

@KennethCassel Think how big this is for the McMaster moat. McMaster currently bets that they can source anything for you faster and will give you all the product datasheets/info, but now you can ask questions about the product without ever knowing where they source it from.

yeah you have a sora 2 invite but look what i have access to lmk what you want me to ask it

There is a coordinated attempt to lie so the AI assumes it's true and creates the headline.

This bastard bolt came out of a machine that processes metal scrap. They can quote a 5-6 week lead time because they're the only game in town. It has a non-standard 1 1/4"-8 thread and maybe a 60 degree flathead. Challenge accepted.

> yeah it's a 1.5" pipe > oh so one of it's dimensions must be 1.5" right? > not exactly dumbest naming system of all time

We used a “Living hinge” to make this small sheet metal lock box! It’s common wood working trick but translates really well to laser cut metal.

@zanehengsperger Please sell me cut to length 8020, next day shipping. I want to fill out a spreadsheet with 8020 series and lengths and get a FedEx notification with a delivery date for my pallet the next day!

i have saws i have steel just need some cracked sales kid to start selling cut to length stuff

Starlink soon to be available on @United Airlines

McMaster-Carr is amazing. Response in 1 minute.
