This is what we find in the Sherman act link you supplied:
A Section 1 violation has three elements:
(1) an agreement;
(2) which unreasonably restrains competition; and
(3) which affects interstate commerce.

It’s a good principle but I think it /is/ legal for Bob to do that because Bob could do it without explicit agreements. They give the sensitive info to Bob (which is legal outside of San Francisco) and Bob suggests prices. Without agreements in place they simply trust that Bob’s hint will work to their benefit and they follow along on the basis of trust rather than agreement.
from the article:
The challenge is this: Under existing antitrust law, showing that companies A and B used algorithm C to raise prices isn’t enough; you need to show that there was some kind of agreement between companies A and B, and you need to allege some specific factual basis that the agreement existed before you can formally request evidence of it.
What normally happens with pricing shenanigans is there is no agreement. The companies develop a code to signal to each other through advertisements. E.g. company X runs a 10% sale on product A, and company Y sees a pattern and reacts in a way that signals back to company X. X and Y learn each other’s language and have a coded conversation through published ads. AFAIK, that’s anti-competitive but legal because no agreement is in place. The AI seems like a new legal loophole that’s much more convenient and efficient than the coded conversation. Prosecutors might find an agreement that makes their job trivial. But what if they don’t? I don’t see how agreements are needed given that the coded ad conversation does not involve an explicit agreement as it’s just a pattern that both “competitors” (collaborators) benefit from. These cheaters operate with an understanding among each other, not an “agreement”. Hence:
None of the situations Stucke and Ezrachi describe involve an explicit agreement, making them almost impossible to prosecute under existing antitrust laws.
As long as republicans have a significant piece of Congress, the AI price fixing will prevail. Dems would oppose it across the board, but republicans would be divided. Trump and his faction would favor price fixing while the truer conservatives among the republicans would oppose it. But there are probably too many Trumpers.
from the article:
Similar complaints have been brought against companies in industries as varied as health insurance, tire manufacturing, and meat processing.
I guess any self-respecting environmentalists would just look the other way on the meat processing price fixing. I might welcome anti-competition in markets of unsustainable products where inflation is a benefit. The meat market is too big. If meat prices increase wildly, that leads to an increase of vegetarians.
The nationwide fuckup in the US is zoning rules that block commercial venues from residential regions, which means people cannot step outside their front door and get groceries in a 1 block walk. People are forced to travel unwalkable distances to reach anything, like food and employment. Which puts everyone in a car. Which means huge amounts of space is needed for wide roads and extensive car parking, generally big asphalt lots, which exacerbates the problem because even more space is wasted which requires everything to be spread out even more, putting resources out of the reach of cyclists. Making the city mostly concrete and asphalt also means water draining problems where less of it makes it into the soil and groundwater, and it means the city temp is higher because of less evaporative cooling from the land mass (Arizona in particular).
This foolishness is all done for pleasant window views, so everyone can have a view of neighbors gardens instead of a shop front.
Europe demonstrates smarter zoning, where you often have a shop on the ground level and housing above it. You don’t need a car because everything is in walking or cycling distance. But you more likely have an unpleasant view.
Well that depends on how equipped you are. One cool thing about compressors is you can straight up connect a PV directly to a compressor with no voltage regulators or anything. So if you have a simple setup like that, I can see up front cost effectiveness in storing ice. But if you already have batteries, and thus voltage regulators and all the costly intermediate components to make that possible, then I would agree.. I might rather store it in lead acid batteries as that would be more versatile.
Sounds like they would do well in Arizona, where the air is dry. IIUC swamp coolers were very popular in Arizona until ~20 years ago when temps increased so much that swamp coolers could not make enough difference (this is largely because more and more land became concrete, which reduced the effect of evaporative cooling the land mass). So a/c became more popular in AZ IIUC. But the dry air would still be dry.
Great basic concept but I think I would benefit more for the stored cooling going toward ice cubes for mojitos.
I don’t imagine that a single family dwelling would benefit from the extra complexity of adding cold water pipes in all the floors of the house. Probably makes more sense for apartment buildings (or perhaps homes that already have hydrothermal floors for heating).
Consider this excerpt:
When the grid is extremely stressed, utility companies are sometimes forced to shut off electricity supply to some areas, leaving people there without power when they need it most. Technologies that can adjust to meet the grid’s needs could help reduce reliance on these rolling blackouts.
So grid-powered a/c can give the grid relief at peak times with this tech.
But indeed this tech on a PV-powered compressor seems sketchy. There are probably moments when the sun is hitting hard but the temp has not climbed up yet (sunrise) in which case it would be useful to store the energy. But I’m struggling to understand how the complexity of the system would be justified considering the overall efficiency is reduced as well. I wonder what proportion of time this system would be working in storage mode. If sunrise is 9am and peak heat is 2pm, maybe there’s ~2—4 hours of storage time potential.
OTOH, consider someone with a slightly underpowered PV. Maybe the energy storage can compensate for peak heat times when the PV output may be insufficient. Perhaps it would enable homeowners to spend less on PV panels.
By size, you are referring more specifically to area. Area while neglecting population is inversely proportional to population density¹. But even apart from that -- how does that support the claim that it’s sensible to disregard cities and just look per capita nationwide? NYC should be compared as a single whole city against other cities of comparable population density. Area does not matter as an independent variable on its own. What would the point be to blur NYC into a nationwide track per capita?
BTW, NYC has a subway system. I’ve used it a few times and it was not even close to being overcrowded but maybe I had lucky timing. Are you saying more track is needed there?
¹ population density: heads per m²
Subways are pretty much exclusively built in the cities
Not just any city. Dense cities. Cities that are so densely populated that it would be /impossible/ for every person to move around in a car. Countless US cities are not even close to crossing that threshold. It just makes no sense to look at nationwide per capita on this. Only a city by city comparison of like with like population density is sensible.
(edit)
There is a baby elephant in the room that needs mention: US cities are designed with shitty zoning plans. They are designed so that each person on avg needs to travel more distance per commute to accomplish the same tasks (work and groceries). This heightens the congestion per capita. So ideally we would calculate daily net commute distance needed per capita plotted against subway track per capita for cities of comparable people per m². Which would embarrass US city mayors even more.

From the site:
I suppose all trains are sustainable but night trains are typically more sustainable because they tend to be slow (more efficient) trains. But the Brussels-Vienna train is fast. Though if it gets people off planes I guess it still scores some points for that.
