@sdamico I want power packets. Go to 480v DC, but the hub can cut in a microsecond if there is an issue. Heck, milliseconds is probably fast enough- at each cycle, hub determines what the other side wants and whether wiring is in tact, no ground/negative fault, etc.

@idlehandsdev Would probably cool too fast to flow beyond 3-4mm. A second mixed epoxy injector would be smart tho?

I could definitely see this being an infill method

@DefunctWebs @cwebbonline Take space below geosynchronous orbit and scale it to a room with 10’ ceilings. All air traffic is around 0.75” off the floor. Nearly all man made satellites are smaller than air born dust and far less numerous than said particles. It is a hard scale to contextualize.

@cwebbonline Honestly, I feel like half of this shit is space garbage. They’ve been saying it’s at critical mass for years. A few meteors hit the garbage and it starts cascading into others until it’s a giant ring of busted up satellites crashing down to earth.

What is happening? Because normal left the chat months ago. 1 week, folks.

@farzyness Today _was_ Tuesday. That leaves 3 possibilities and I don’t see it happening tomorrow (?!)

OH. MY. GOD.

@RichOToole … and both are authentic?

San Antonio is a wild place. You will hear death metal blasting in a Mexican food restaurant.

@TiredActor In some cases, they don’t.

I don’t understand how parking garages work and it’s too late for me to find out

@JonBbC_TechGeek I need a rewatch. Has been ~40 years??

Just watched this movie w/ my kids. Such a great one! Brings back memories from when I was 6 years old. 😂

@Scobleizer @humanoidsdaily @tbpn It’s going to be some of both. Ironically, the wealthy may eschew robot help longer than the middle class and the working poor.

@humanoidsdaily @tbpn He is completely out of touch if this is what he believes. People don’t have the resources to change their homes that deeply.

Mark Cuban isn't buying the humanoid hype. 📉 On the @tbpn podcast he predicted humanoid robots will "fail miserably" within 5-10 years. His logic? We won't build robots to fit our homes; we’ll redesign our homes to fit "optimal" robots—like spider-bots and robot elevators. 🐜🏠

@elonmusk Make it so I can go to sleep in my Tesla at 11pm and wake up 8 hours later 500 miles down the road.

I would like to offer to pay the salaries of TSA personnel during this funding impasse that is negatively affecting the lives of so many Americans at airports throughout the country

@cat240359 @sydney_ev Time will tell.

@JoeTransue @sydney_ev Sure.

Yes. Even serious farm equipment can be electrified. Of only we had more foresight and encouraged the electrification of heavy machinery.

@mattparlmer You do realize they are never going to ship millions of LiDAR cars, right? If a LiDAR based L5 vehicle ships (from any vendor) it is going to be despite the tech, not because of it.

Hahahahahahahahahaahhh

@derek_j_morris Let the kids enjoy their make-believe?

@mattparlmer It’s a ground truth system to verify ML depth…

@Alicoh1 @Tommers71 @ZaidJilani Along the lines of “there are lots of sick people in hospitals. If we ban hospitals, health will go up!”

@fartdoodle68746 @kilianhekhuis @radioactivered If that farm land was growing corn for ethanol, it’s a net energy positive. The concerns about land use are not zero but they are way over estimated.

@kilianhekhuis @radioactivered You're right. We should just bulldoze a few million acres of forest and farm land to put more solar panels and wind turbines.

You mean the offshore wind turbines? My first career was wildlife conservation, so i’m glad you brought this up. 😊☢️ When offshore wind turbines are built, the noise from pile driving can stress or disorient marine mammals like whales and dolphins, the sediment stirred up will also smother bottom dwelling organisms such as clams, crabs and some species of aquatic worms. The structures themselves alter currents and sediment patterns, which can shift habitats and affect feeding and breeding grounds for a lot of species. Overall, marine mammals usually experience the most noticeable behavioral impact from offshore wind turbines. Over time, sure the foundations will act a lil bit like an artificial reef and attract some fish and invertebrates…but this can also disrupt natural predator to prey relationships. Small amounts of metals from cables and some coatings on turbine parts and leaks of lubricants or hydraulic fluids during maintenance can also enter the water. Other concerns (that I have already mentioned btw) is interference with bird migration and bats with somewhat potential changes to water quality in localized areas too. It’s not “super” catastrophic sure, but these turbines DO and WILL introduce both physical and chemical changes to the marine environment that need better careful management….that nuclear does not. Nuclear power plants don’t physically alter marine habitats on this scale, while they do use water for cooling they don’t create structures that disrupt ecosystems or release materials that smother or stress marine life in the same way.

@onyxwhiteyeah @niccruzpatane @thingsshldwrk I can promise you that every one of us does something equally dumb at some point or another, as seen from an outside perspective.

@JoeTransue @niccruzpatane @thingsshldwrk You should get smarter friends

Prototypes Building prototypes can be hard sometimes, but it’s one of my favourite things to do. Below is a photograph of Chicago Pipe One, the first reactor prototype. It was built in a squash court by Enrico Fermi in 1942. Some 25 years ago I built a 3D CAD model of Windscale Pile One for UKAEA. The Windscale Pile was a huge production core but it suffered a catastrophic Wigner fire in 1957. I was given copies of the original engineering package and manufacturing drawings from which to produce the CAD model. Some of the precision machining from the 1940s was difficult to believe, and the hand drafted GA was an incredible work of art, that should be hanging in a gallery if not for the reality of that one marking in the title block. Anyway, prototyping… What you will often see is that American teams will do early prototyping, often scrapping many early iterations and learning much about design for manufacturing, assembly, and test. European teams will often run a lot more operating simulations in the initial phases and will deal with manufacturing and assembly later. Once you live through the process on both sides of the Atlantic you see the fingerprints of both approaches in the products. But of course once you understand the differences, you can follow whatever path you like. You can do one or the other, hybrid, or mixed. Like most things in engineering, this deeper understanding just makes you better at all approaches. Prototypes… Sometimes prototypes are small, cheap and easy to do, sometimes they are big and expensive. A prototype nuclear reactor is the latter. This is why it often makes sense to build a non-nuclear prototype first, especially if you have a series of novel proprietary technologies that you intend to carry into a full product design. Often it makes sense to build multiple prototypes, perhaps one for each major proprietary technology that you are developing. This can be especially useful if your proprietary technology fundamentally changes the economics of the product category. Perhaps with entirely novel use of thermodynamics to solve long standing technical challenges, or deliberately selecting a more challenging neutronics arrangement because it switches a supply chain crunch for a supply chain glut. Smart people will usually identify the load bearing assumptions around your claims and will seek to kick them out to see if they are robust. Prototyping is the best way to substantiate your claims around your novel proprietary stuff, because theoretical is subordinate to empirical. Also, hardware is cool. Prototyping also demonstrates execution, and provides an auditable record of your capital efficiency and capital discipline. World class prototyping isn’t just technical success, it’s your risk control and capital efficiency. Things are often much easier if you throw more cash at them, what world class looks like is a rapid, cost controlled and risk dissipating technical success. Sometimes the product system is extremely complex, think a space shuttle, or a nuclear submarine. In these cases the R&D and prototyping is often staged and sequenced, and much of the system design is complex integration work around boundaries and interfaces. Such complex developments are rare. But sometimes you get the opportunity to do something so ambitious, in such a large design space that developing the program is an R&D exercise itself. In these cases, you need to design a risk dissipation machine and that means a program with a multitude of empirical prototypes. Dissipating such risk safely, rapidly, efficiently with private capital constraints can be a real challenge. But any worthy challenge should be sufficiently difficult that nobody other than yourself really understands what has been achieved. Historically the biggest and most complex challenges humans did were undertaken by public programs, as they were military assets. This is no longer the case.

@cat240359 @sydney_ev Plural decades is not a timeline. Mining operations are going to adopt autonomous BEV inside of approximately 1 decade. Obviously, there will be some hold outs, but barring draconian legislation to stop it, the tech ramp will be extremely steep.

@JoeTransue @sydney_ev A 20-100% more expensive, than the diesel options, the changeover seems many decades away.

@azraelfallen @niccruzpatane @thingsshldwrk Sunk cost fallacy? Seriously I think people look at something they spent $25k and think “double or nothing?”.

@JoeTransue @niccruzpatane @thingsshldwrk Why did he do that????

@DavidWe75281836 @sydney_ev 🤦‍♂️

@JoeTransue @sydney_ev You clearly aren’t going to listen to anything. EV’s are fine for light duty applications like automotive. Useless for heavy duty. The only industrial sectors interested are ones were its being legislated and in those it’ll make the cost of getting that work done 4x more expensiv

@DavidWe75281836 @sydney_ev Read your _own post_. EV mops the floor with combustion in almost every sector except flight. That’s all baked today. You don’t have to believe me, but if your career is on the line (and anyone depends on you keeping it), you should at least learn the other side of things.

@JoeTransue @sydney_ev I didn’t say it wasn’t reliable. I said it guarantees downtime because it can’t do a days work without stopping to charge multiple times. The duty factor in automotive is about 10% and EVs just about work. Off highway industry works at 50%+, so has no chance
