    Generator load sharing

    AC bus? Then it's closer to the operation of grid level load distribution, and is indeed not really intuitive for regular EEs. Small changes in frequency, phase ending with drastic changes in loads...

    Gravity Based Electricity Generator

    Overthinking. You only need a big treadwheel. But honestly ... this just won't go anywhere.

    Gravity Based Electricity Generator

    You have ~ 24.5kJ energy in that (height*mass*g). That much can feed 1kW load for 24.5 seconds. If done right, then the rated power of the motor/generator will determine only the maximal load the system can handle.

    Baltimore's Francis Scott Key Bridge Collapses after Ship Strike

    ? For every complex (electric and other) system has regulations how it is built, how it is operated and such. That's what makes 'safety' more than just a word. If there were outages on that ship then somewhere, something was not up to code. Restore power is just one thing. Finding the root of...

    Baltimore's Francis Scott Key Bridge Collapses after Ship Strike

    By 'fixing a power failure' you mean getting the power back or ensuring that everything is really up to code?

    Likely some soldering (or other kind of contact-) error.

    Random Thoughts 7

    Company stuff. The SW dev guys at the other desk had a though fight even just to have some Linux running, and at the end they were banished to an isolated network with that...

    How Dangerous is Editing the Windows Registry?

    If you do know what you are doing (and has a backup) then it's fine: there are problems when there is no way around it (it's the easy way around many other problems, actually). If you don't, then it's just like Chernobyl.

    B Strange cosmic particles in my detector

    I think it'll be the 'another'. That detector has no selectivity at all, and since it's not anything specially built for the role (shielding, noise control, meticulous care about any possibly unstable materials and isotopes in structural parts, cleaned for external contamination and sealed in a...

    Appliances Knob not tightening right

    I think the point needs to be precisely centered for this role.

    Appliances Knob not tightening right

    Filer/sandpaper and electric drill/screwdriver. Fix your knob into the drill and set it to (very) low speed. Put a nut on the knob first, so you can fix the thread just by removing it. Also, that plastic 'knob' part just makes it convenient to be used by hand, but usually not really helpful...

    Does a shaking hammer blow cause less damage than a stiff blow?

    No general answer. Some techniques are focused on maximal impact damage, others are focused on speed and utilizes the reflected forces to draw back and some are about maximal transferred momentum (to sweep a leg, for example: without breaking your own).
