    Lightning

    I also watched Will's video, the truck had some neat features, but obviously isn't sorted out. I think the larger issue is the third party charging stations. It will be an issue for anyone wanting to go farther distances from home. Will had trouble finding functional charging stations...

    Power station attacks…..

    Well, there's a couple possibilities. Lone wolf pissed about something, or a test. There have not been many details about the timing. If both stations were hit within a couple minutes of each other, we would know that more than one person was involved.

    Power station attacks…..

    A damaged cooling system will allow more time to escape before temp monitors start triggering alarms and shutting things down. I guess if the transformer has a pressurized cooling system, a low pressure alarm would still go off pretty fast, but not like shorting the windings. Thats off line...

    Power station attacks…..

    Car doors aren't made from 3/8" plate. Slugs do indeed go right through thinner stuff.

    Power station attacks…..

    Yes, we were. A standard slug just mushrooms when hitting plate, much like a 22LR would. The plate might bend, but the slug will not make a hole in it. At least, that has been my experience when trying some of these things.

    Power station attacks…..

    Slug would be too big in diameter and just put a dent in the case unless it was tungsten sabot dart or some other harder metal and shaped properly. 5.56 FMJ will go through 3/8 plate pretty easily, as do hollow points and soft tip rounds. Add green tips and go up to 308 or 30-06. Pretty easy...

    Power station attacks…..

    I'm good as long as they don't bring down the station my grid section is fed from ;-) I think that incident knocked 10,000 people off line for a while.

    Power station attacks…..

    The main issue is that there's nothing a couple of guards can do to prevent someone taking a few shots from a distance at night. Most of the sub stations around here are surrounded by trees. Those that are not, are close to populated areas, so even then returning fire would be risky. Most...

    Power station attacks…..

    Local article said the windings are damaged, the transformers are not repairable. https://www.wral.com/gunfire-damage-led-to-moore-county-blackout/20612201/.

    Power station attacks…..

    Agree, part of the problem is that a lot of the transformers are not Off the Shelf units, so you may not be able get another one from another utility. We may find out how long it takes to get a custom transformer ordered/delivered before this is all said and done. Current estimates are to be...

    Power station attacks…..

    Yup, easy targets. Latest info is some transformers were shot at and they are trashed. Hopefully, there are replacements somewhat locally. otherwise those folks are going to be without power for a while. 60 minutes did a story many years ago about the vulnerability of the sub stations, noting...

    Any recorded line worker deaths/injuries from domestic grid tie solar?

    Power company pulled the meter of a place that was found to be back feeding after hurricane Fran paid a visit to North Carolina. Those folks waited a long time to get things turned back on. Pretty sure there were fines involved as well. A few folks died from carbon monoxide due to running...

    Help with emergency setup

    One thing to keep in mind is portability and structural damage that may occur during a hurricane. Having a big, fixed system assumes you still have a roof, solar panels and intact electrical wiring when it's over. When Fran came through North Carolina, there were sections of town where the...

    Best way to utilise a portable solar panel

    Don't think of it as wasted money, consider it a spare, or you can use it with another battery to power something else after the next storm hits. MSW power is better then none at all.
