State wants all electric line buried soon too. |
Yeah, good luck with that. Ever try to insulate a 500 kv 3-phase line that's carrying a thousand amps or so? Not so easy... Around where I live, they've buried the 2 kv feeders which feed the local distribution transformers that power groups of houses. 2 kv is certainly doable - except the state made them take the sump pumps out of the underground splice boxes which removed leakage and rain water. Can't have that 'polluted' water pumped into the storm drains, you know.
So, after a few November rains got the boxes good and wet, and everyone fired up their electric ovens for Thanksgiving all at once, they would burn up a couple thousand feet of underground 2 kv feeder (and create a s...load of polluted water in the process). Took 4 or 5 hours to pull in new cable and get everything up and running again. That's why I now have a gas stove, a 5 kw generator (stored 'dry'), and 5 gallons of stabilized fuel for it. I've used it several times on holidays. I can bring the whole house up with it (at reduced load, of course). Next door neighbors have come knocking, extension cords in hand, because the electric 'pilot' on their gas ovens wouldn't work... _________________ '71 panel, now with FI

it is all par for the course. We are about to pay to reinvent the circle because that is the direction we will be going. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

On that note....this is one of the most informative videos on LARGE underground powerlines I have seen. This is kind of a case study on one of the most famous and important underground powerlines feeding LA....and how they are insulated...and why they are almost impossible to repair.

If you make electricity with a second alternator it’s free, so you can then run a compressor to make free ac cold! Put a third one on and then you can make the whole car electric, a fourth and you can sell electrons back to the grid
Cars need a lot more cooling capacity than houses because of duty cycle, starting conditions, peak demand, solar load, thermal load, and conductive/ convective load.
An electric one will suck. |
we have to if we will be getting rid of gasoline by 2035 like in California. Current blue states are clear on this issue. Probably run a belt off an axle up to a gear, over to a lever to a bucket that twirls and then into a leather strap that turns the AC pulley. |
2 year old thread on putting AC in a bus = California will ban gasoline by 2035.
except they won't, the announcement said they'll stop selling brand new cars that run on gasoline by then. except they won't, because promises made that far in the future by politicians mean basically jack squat. it does however make great fodder for political shirtposting |
