It's actually pretty interesting. Most high voltage lines are
aluminum where the increased resistance is much less of a factor
at say 100000 volts or so. Even the 200 and 400 amp underground
service lines are turning to aluminum due to copper prices. Raw
aluminum manufacture is extremely energy intensive but once it's
made reforming it and re-extruding it is not as bad as steel.
There is talk of running a smelter only during off peak hours in
the future or when the wind forecast is good. The whole grid
needs to be rethought if we get serious about greening it.

Can you calculate a projected cost for the aluminum for the
project at today's prices? That would be interesting.
RE
[/quote] I admit that is far outside my skill set. But who is to
say that a new grid is the solution ? Here is a good article
showing how we have no idea how it all shakes out:

So no grid just a stream of hydrogen supplying power plants
possible via existing pipeline infrastructure... Solves the
intermittent nature of wind and the overproduction problem in
times of plenty.
At this stage who the jesusfuck knows.

I bet K-Dog could work it out. :) If I had a bit more energy
and motivation to do so, I think I could do it.
What do we need to know?
We can simplify the problem a bit.
Just picture ONE offshore windfarm. It really doesnt matter if
it is just one or many spread all over the place.
How many of the BIGGEST f*cking wind turbines we can make does
it take to produce 30 GW of power? How much does each one
currently cost?
How far apart do you space them out at sea? From the photo it
looks like maybe 500 meters.
Now you need to connect them all together with aluminum cable.
How thick does that wire need to be to carry the load from each
turbine?
Then you need to know how thick your cable needs to be to carry
30 GW of Juice. It would not be much different than 30
individual arrays each carrying 1 GW. Then the mileage to the
substations (20 estimated) and how much it would cost to build
such substations. But that is past the scope of this exercise.
All we are looking at is the aluminum cost for the project. Not
the labor costs or anything else.
It's a doable problem, just would take some researching on the
load capacity of aluminum wire, which I have no clue on. After
that, it's just multiplication.

I'm no electrician or electrical engineer, but know a little
about AC and DC cabling difference, which is a lot.
I do not see any transformers/inverters from the wind turbines
when I passed them in a ship hundreds of miles from where any
power is needed. Are there transformers/inverters inside the
masts, or underwater? I do not know, but it would make a giant
difference to the cabling requirements. I think it would be very
difficult from an engineering standpoint to overcome salt water
corrosion in venting and cooling the transformer/inverter. It
may be that they are in the mast below water and the water
around them cools the fins, so no ventilation is necessary. I
assume that is the case, as DC current over hundreds of miles is
not possible due to the heavy copper cable requirement. Perhaps
someone can research that, I don't have time. Assuming the
current is AC, aluminium would need to be very well insulated.
They can't be naked as in overhead transmission lines.
You then have cost of not only aluminium, but rubber and I
assume, piping which would need to be corrosion resistant,
probably PVC. I don't know if naked aluminium inside PVC is
possible. I doubt that would be what is used though.
I don't see cost as mattering at all, the messaging is that
endless trillion$ will be spent as in a war. That is not my
analogy, it is literally what the spokespeople for the elite
movers and shakers such as Prince Charles plainly enunciate. The
great reset, aka 6uild 6ack 6etter ( fun fact, every healthcare
provider in Oz, including yours truly, now has a login number
beginning with 666), is a technofuedal reversion to a two class
system instead of the age of oil's three. Herr Shwab, son of a
Nazi collaborator and student of Kissinger, says you will own
nothing and be happy. Unlimited printing and inflation doesn't
matter to the billionaires, as they are the recipients of the
largesse, while middle classes must fold. All your 🍌 is
yes ok Blackrock and Vanguard. Standard of living doesn't need
to drop for those at the top.
It's interesting what NF mentioned about plans to run smelters
during off peak and when the wind blows. I've always thought
that it only makes sense from a sustainable standpoint, to stop
having industries that produce goods perpetually and only as
needed. This means govt car fleets are not replaced after 20'000
miles and you or I don't replace things when they are out of
date, but when they are worn out. Your Vax status and social
credit score will determine whether you deserve a new mattress
or couch. Failure to adequately endorse big brother, or post
pictures of puppies instead of independent thinking will switch
you off and sink into the springs.
The growth based paradigm is over.

I am not saying this is a great project the article is just a
puff piece. If you wanted to know what I thought the future grid
looked like this would be it. Production tied to an industry
with a surplus to the grid. It's almost a return to the past
when mills harnessed water for industry and as a sideline
generated electricity.

Here is an interesting way to store solar energy. You need a lot
of CO2, but this looks pretty neat to me.
[/quote]
Hi Cam, PV magazine posted a more detailed article about the CO2
energy storage proposal. I found it went into the tech details
more. The take away I got was it's supposed to be a space saver
over standard compressed air storage because of the reduced
space requirements of compressed CO2... It's all interesting
