  • I’m not a meteorologist, but I do know a thing or two about plasma.

    Plasma is very short lived. Think on the order of microseconds at atmospheric pressures. So unless there was a massive linear source of power along the whole length, this isn’t plasma.

    The visual effects probably have to do with the fact that the sun was very low. I’m guessing the particle size distribution in that line is notably different from the size of particles in the clouds surrounding it, leading to much stronger reflection of evening light.

    I am curious as to the meteoroligical explanation for the line though.


  • Did you measure voltage drop across the pump while it’s trying to start up? The voltage will only drop when there’s current being drawn. So with the pump off you would see full supply volts even on a highly resistive line. You could try lugging a battery down to the pump, and jump it to get it started, then remove the battery jumpers but keep the pump running on your main run, then measure the volts across the pump.

    Or you could try to measure the resistance of your wiring with your meter. You would disconnect it from your 12v source, then short the pump side, then measure the ohms across the pair at the source side. Also measure the resistance across your pump windings when it is disconnected, but with the switch on.

    I’ll throw out some example numbers. Say you have a pump that says it needs 6 Amps. Chances are the inrush current is more like 12A. If you measure across the terminals with the pump disconnected from power with the switch closed, you might measure around 1 Ohm. Now if you measure your very long supply line and get 2 Ohms. Then you would only get 12V/(1+2 )Ohms = 4 Amps through the whole system. With the pump drawing 4 Amps you would only see 4V at the pump terminals when it is already running.







  • I use lactose free whole milk, maple syrup, a generous amount of cocoa, vanilla extract, cinnamon, and sometimes a touch of nutmeg.

    My wife likes to go really heavy on the cinnamon and adds some cayenne pepper for more of a mexican chocolate style drink.

    Delicuous indeed.

    Cocoa does contain some caffeine, so people with no tolerance at all might not be able to enjoy it, but it’s something like 10% the amount that’s in coffee.



  • I had a hard time finding whole bean decaf. Counter culture: slow motion and magnolia coffee co: Brazil decaf are too options that I like fairly well.

    My sensitivity to caffeine varies. When it starts to bother me, going to approximately half decaf and half normal beans is a good way to cut the caffeine without having the shock of suddenly switching to decaf only.









  • I’ve had that happen with what i assume was a hand lotion because there was a particular part of the lid that smelled.

    I don’t know why other people are treating you with so much disbelief. This absolutely can happen with people not thinking about how their habits impact what customers are consuming. With how many millions of coffee beverages that are served every day, it shouldn’t surprise anyone that some small portion are handled improperly with poor hygiene. It also shouldn’t be overly surprising if you’ve had it happen multiple times because you likely visit the shops near you. Such an event isn’t random and is the result of someone’s bad habits.


  • No, never. Current charging rates already get close to thermal constraints. Hitting those charging rates either requires accepting much lower power density or using way more metal per cell. This research might inform design changes to improve charging rates, but we’ll never see high capacity batteries charging in a minute.

    The researchers know this and only mention wearables and iot devices applications. The article author erroneously makes the leap to high energy density devices.

    If you don’t care about energy density at all, ceramic capacitors can already charge and discharge in microseconds.
