Three of the four gas stations in our area had product to sell and no

truck delivery later today.
We had spot shortages here and we don't even get our gas from that
pipe. Nobody in the peninsula does. It was just panic buying AKA a
media driven emergency. Now that everyone has every gas can and
tupperware bowl full of gas, supplies are recovering. I still got gas
yesterday at my regular station no line no problem regular price.
Cracks me up though. Responding to the alternative methods to deliver
fuel, Biden's Energy Secretary stated that the pipelines
are the better way to transport it even though her boss axed the
Keystone pipeline.
Then she thumbed her typical liberal nose at the public by saying
that if people used electric vehicles, they wouldn't be experiencing
these fuel shortages. She also happens to own stock in an electric
bus manufacturer that Biden visited to promote.
The value of her stock holdings are potentially worth $ millions
and she has not divested her holdings even though there's a
conflict of interest issue.
But what really cracks me up is none of these electric vehicle
advocates ever mention where the energy comes from to charge
up their electric vehicle batteries. The vast bulk of it is
generated by fossil fuel plants. Plus, whenever energy is
transformed from one state to another there are losses involved.
Laws of physics prevail.
There are also the I2R losses in the transmission lines. A while ago
one of my inspector trade rags had a story "How hot are those
conductors?" talking about how hot some transmission lines run and how
that affects line sag but the fact remains that is waste heat going
into the air.
It is hard to get the utilities to say how much power is wasted in
transmission and the crazy bookkeeping they use on the grid makes
those numbers hard to actually believe when you see them but it is a
pretty big number if your power is coming from very far away.
I2R still wins in the end.
I'm sure you know that's the reason the transmission lines are run at such a high voltage.
It minimizes he losses, but there are still some. The company I used to work for put in
some equipment for a regional power company some years ago. They told me about an
incident where, in the middle of the summer in a coastal SC area, a transmission line that was
hot and sagging separated at a badly crimped barrel "butt" splice. No one was there to see it,
but when it separated it produced a fireball that, when it hit the ground, blew a big enough hole
to drive a truck down into and hide it. They said there were clumps of fused sand laying around.
That would have been cool to see, just not too close up.
Some of the "high tension" power lines run at *very* high voltages ...
in some cases in excess of 200,000 volts.
That is not even close to how high it can go. It can be a megavolt on
true long distance transport. The one behind my house is a single
triplex 230kv "high voltage" line and two 26KV "medium voltage" lines.
The HV feeds Naples and the MV lines feed Bonita and South Estero.

This is the HV line, showing the twist.

As for the radiation, because of that twist and the fact it is a
balanced triplex delta, I worry more about radiation from the single
ended 13.5 KV primary in front of my house.
