Ash only once when the filters failed. You’d occasionally get “power station frost”. If the wind was in the right direction on freezing days moisture from the cooling towers would freeze to give a 100m wide avenue of thick haw frost. There’s a lot of big transmission lines that aren’t pretty and buzz when it rains. (wind/solar don’t need lines this big)
USB-C is an absolute shit-show. Half a dozen types of identical looking cables all with different performance and compatability. They can be power only, USB-2 only, USB 3, 3.1, 5gb, 10gb. Some can carry 5A, others only 3A. Some may support thunderbolt. Cable sellers and manufacturers can/will claim anything.
For people selling USB-C devices it’s a massive support problem. It looks like the device is defective, but someone may just have swapped out the cable for their phone charger cable and there’s no way of telling.
