    Boeing has a similar vehicle that drives the rear end of long load trailers around Seattle. https://www.youtube.com/watch?v=wsZ6YPsPpj0

    I love it! Was the inability to turn down the volume on the mini player intentional? This had me laughing. I'm at work, but that's metal AF.

    The way they wrote it is confused and misleading. I suspect it's a corporate piece to sway people to buy glacial-whatever water.

    how about you pick a title that makes it clear its' talking about crypto and not orbital mechanics next time.

    This is the most likely reason. They should have put a sign, but the ramp looks right to me if you want them to match pedestrian speed when merging into a pedestrian space.

    I am an Engineer and have done things both ways throughout my career. What is easy to miss in digital are the overall holistic design and the way it all fits together, because you …

    This was obviously not a good system design, but a box full of relays and PLC controller cost a whole lot less than the all-in employer cost of an extra employee. They really shoul…

    The scary part is how much real interpersonal communication data they have on users and what could be done with it in the wrong hands. What is their real business model? It can't j…

    Because gaps like this multiply out at the end of a beam. If for example the abutting structural member relies on that joint for support and is 12 feet long (144 inches) and lets s…

    Which is why we usually have multiple cylinders to deliver smooth power. A V8 is getting power on 4 cylinders each revolution, etc.

    I see no reason this thing wouldn't lose compression or backflow exhaust gas after wear-in, and wear-in would happen quickly with the cyclic load on those ball bearings. It's a pre…

    The newer Speed Queens are barely audible. I have to listen for the water sloshing to tell it's even on.

    Guesses poorly too, based on the examples. The crack growth example is almost laughable. These are nowhere close to where real cracks would form. Cracks start on the inside corner …

    A static weld is usually stronger than the base metal under static conditions (i.e. not undergoing dynamic shock loading). Welds are created at 3000 degrees C with 50-100C metal ri…

    Perhaps its a bad article, but I can't see the value of solving the boson sampling problem by sampling bosons having any application in general computing.

    Exactly. This sounds like pure propaganda. They're measuring experimental results and calling it a computer.

    Renewables won't buy an industrial power user out of the grid, they need reliability. Also, location is more important than what the power bill is for most industry and commercial.…

    These are wrecked cars, however. Who is to say that the batteries don't have hidden damage that could cause them to blow on a fast charge and cause a fire? We already know Teslas h…

    Among US utilities, local public utilities seem to work best. Federal run facilities are deeply mired in bureaucracy and acquisition guidelines, while fully private power companies…

    Pinterest drove me up a wall with this. I didn't sign up for 4-5 years, and only because I actually needed to see an image for work, because the arrogance was annoying. I have a pe…

    That's for peak power. Efficiency is lost in the deformation bending and returning of the walls of each tire as it rolls. i.e. A really highly loaded tire needs to be really well p…

    The Skype client of today is just a renamed Lync client, which actually used to be decent. They've done nothing but make it worse since Lync ceased to exist.
