It is such an up hill battle to set yourself up a fully functioning car garage and build/maintain awesome vehicles when the only way (at least that i know of) is to charge your welder with batteries. Myself i’ve never seen anyone powering a welder with batteries (yes i know this is the future) but here in reality you just hook it up to a generator and feed it petrol. Out here in rural WA (Western Australia) generators are as common as flies (and all farms have a large cache of petrol/diesel as well), if cataclysm happened here i know i’d be grabbing one for sure.
Also most generators are REALLY NOISY, which means zombie attraction, which means !FUN! (you can buy quiet ones but it’s not like cockies [farmers] give a damn about noise when they’ve got 100 Hectares)
I’ve been dicking around in the source but i’ll be buggered if i can work out how to give an item the ability to power an item (and only when it is in a certain radius of the generator) then remove the charge when the generator is off.
There would be no need for power cables because i think we can use the fact it’s the future and say that we can make tesla coils without cooking everyone with microwaves, but a corded system would be more flexible (allowing the generator to power items some distance away (Electric fences!! Fridges, lights, security perimeters, cookers, traps… oh what fun could be had)
