China's Ultra-High Voltage Lines - Thread

1/14

China is building the world's most advanced UHV grid right now.

UHV lines are good for carrying power over long distances. The high voltage level reduces line loss. But they are very expensive to build.

China's UHVDC Network now:

In the rest of the world, UHV lines have generally been used sparingly. Submarine power cables (e.g. connecting UK to mainland Europe) and some huge hydropower projects in Quebec are some notable exceptions.

China is building UHV lines on a scale never seen before.

So why is China different? Geography plays a huge role. China's load centers are in the coastal East and South, while the best wind, solar, and hydro resources are in the North, Northwest, and Southwest. Power (esp. RE) is being generated far from where it's needed most.

In the past, poor regional interconnectivity has been a big contributor to low offtake levels of renewable energy. Of course a glut of coal power also played a role. Curtailment has improved in recent yrs tho. I discussed regional grids before:

UHV lines provide a inter-region backbone to transport power hundreds or thousands of km across the country. The UHVDC lines are used for the longest distances, while UHVAC lines are used for shorter distances, often within the same regional grid.

Ahh fuckit part of my @threadapalooza thread had a clear subtopic and wanted to be its own thread.

Here's the thread about "membranes" as a metaphor for groups of people.


15a/ Membranes. Monists go on about how everything is one, which is true in a sense but also have you noticed that some things are inside and some things are outside? The role of skin, or the walls of a house, or a windshield on a car, is it keeps inside in & outside out.

15b/ Membranes can be applied to groups, and we can talk about a few different kinds of membranes that you might see around a particular group of people:
- closed membrane
- closed web
- semipermeable membrane
- open network

15c/ Closed Membrane: eg a company, family or country. Maybe a way to join it, but you need an active & explicit invitation by the members, whether thatā€™s a job application or a marriage or an immigration process. Lots of intentional community houses are also like this.

15d/ Closed Web: consider a friend group. You don't exactly need an invitation from everyone in the group to join, but you do need to make friends with *someone* in the group. Polycules (except polyfidelity) work similarly, usually.
One of Germanyā€™s most prominent economists, Hans-Werner Sinn, warns of hyperinflation; he links it directly to Hitler's rise to power. A distortion of history: the rise of the Nazis was preceded by deflation, exacerbated by fiscal austerity. Thread /1

https://t.co/hmAz0tsyuv


Sinn says hyperinflation after WW1 impoverished the German middle class in the Weimar Republic: "Ten years later they elected Adolf Hitler as Reich Chancellor." Policy recommendation today against hyperinflation: "tighter budget constraints" /2

https://t.co/ydfxgiCpkD


Sinn thus feeds a widespread misinterpretation. Mass poverty when the Nazis came to power in 1933 was not the result of hyperinflation, which at that time was ten years in the past; it was primarily a consequence of mass unemployment due to the recession in the early 1930s. /3

The Nazis had come to power after years of deflation - i.e. falling prices. From 1930 onwards, Reich Chancellor BrĆ¼ning used emergency decrees to bring about tax increases and drastic state spending cuts that pierced the social safety net. /4


Austerity policies increased unemployment, led to social suffering and unrest. Hitler realised by the end of 1931 at the latest that BrĆ¼ning's austerity policy would "help his party to victory and thus end the illusions of the present system." /5

The solution to this problem is to figure out credible reasons to justify the number of indian military personnel, and the expenses of maintaining this relationship. Once you do that, reveal the details, and they lose leverage to push through this issue. /1


And that means owning up to why Indian military assistance is needed. This requires large national conversation about the threat of Islamic extremists in the Maldives, explain the dangers and the opportunity cost of an attack etc. /2

People will except we'll reasoned decision making. And the public already has a frame of reference to indian military assistance from November 3rd 1988. So none of this is new or a surprise. /3

What is being weaponised is this imagined spectre of loss of autonomy for the country by collaborating with indian military on national security issues. This is an easy problem to solve. /4

The solution is merely laying out how national autonomy is maintained in such a national security collaboration. It's not like the Maldives can defend itself from any foreign military invasion anyways. /5
