In the US, the typical freight car travels an average of 241 kilometers per day when in operation. So the researchers created a battery big enough to move that distance as part of a large freight train (four locomotives, 100 freight cars, and about 7,000 tonnes of payload). They found that lithium ferrous phosphate would let each of the four locomotives be serviced by a single freight car configured as a giant battery. The battery would only occupy 40 percent of the volume of a typical boxcar and would be seven tonnes below the weight limit imposed by existing bridges.

Because of the efficiency of direct electric power, the train would use only half the energy consumed by an internal combustion engine driving an on-board generator. And while an above-average trip wouldn't work on a single charge, freight trains normally stop several times a day to change crew and refuel, providing an opportunity to boost the range with some fast charging. And if longer breaks are possible, the battery cars themselves could be swapped out.

While the system wouldn't require new locomotives, the batteries and charging infrastructure it would need make for some substantial up-front costs. The researchers added up all these costs and then calculated the price of electricity that would be needed to make the whole thing price-competitive with diesel.

Regenerative Agriculture: A Way To Sequester Carbon - CleanTechnica
https://cleantechnica.com/2021/11/12/regenerative-agriculture-a-way-to-sequester-carbon/

On November 7, 2021, food systems experts gathered at the UN Climate Change Conference (COP26) in Glasgow to discuss using investment and true cost accounting (TCA) as levers for food systems change. Those discussions were the offspring of an earlier UN Food Systems Summit white paper that discussed how one of the central problems of current food systems is that many of the costs of harmful foods are externalized — they’re not reflected in actual daily market prices

RADIQAL: je fakt ze teda ufoní biomasu do studie nezahrnuli, asi to neni vyznamna polozka .)

TADEAS: To je dobry! Vlastně, ty delfini a velryby by bejvaly byly schopny tu planetu zachránit. S nasazením vlastních těl chladili oceány.

A ufoni jsou tu beztak proto, aby je zachránili. Šak pod vodou se skrejvaj, kdejinde ;)

Humans are guilty of breaking an oceanic law of nature: study
https://phys.org/news/2021-11-humans-guilty-oceanic-law-nature.html

A new international study carried out by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) has examined the distribution of biomass across all life in the oceans, from bacteria to whales. Their quantification of human impact reveals a fundamental alteration to one of life's largest scale patterns.

...

In contrast with an even biomass spectrum in the pre-1850 ocean, an investigation of the spectrum at present revealed human impacts on ocean biomass through a new lens. While fishing and whaling only account for less than 3 percent of human food consumption, their effect on the biomass spectrum is devastating: large fish and marine mammals such as dolphins have experienced a biomass loss of 2 Gt (60% reduction), with the largest whales suffering an unsettling almost 90% decimation. The authors estimate that these losses already outpace potential biomass losses even under extreme climate change scenarios.

"Humans have impacted the ocean in a more dramatic fashion than merely capturing fish. It seems that we have broken the size spectrum—one of the largest power law distributions known in nature," reflects ICTA researcher and co-author Dr. Ryan Heneghan. These results provide a new quantitative perspective on the extent to which anthropogenic activities have altered life at the global scale.

Vladimír Matajs: od roku 2023 zavede @ERU nový distribuční tarif, který umožní sdílet elektřinu z FVE v rámci bytových domů bez nutnosti často neřešitelného sjednocení odběrných míst. Vyšívá na tom společně s ERÚ fotovoltaický cech CAFT a Komora OZE.

Donziger je tak podobně jako Julian Assange vězněm svědomí v jedné ze západních demokracií, v zemi našich spojenců, což je samozřejmě zcela nepřijatelné i proto, že se tím snižuje legitimita našich snah o pomoc lidem, kteří jsou obdobně neprávem vězněni z politických důvodů jako například Alexej Navalnyj v Rusku

Cop26: Hundreds of scholars brand Glasgow summit a ‘failure’, and call for ‘real green revolution’ | The Independent
https://www.independent.co.uk/climate-change/news/cop26-glasgow-academics-letter-b1955303.html

We are hundreds of scholars from dozens of countries, who are grieving the situation but determined not to ignore it. We believe that the corporate capture and failure of Cop26 clearly show that people in communities and organisations must now lead our own emergency response. That includes coordinated radical policy advocacy from outside of a corporate-driven system, for a Real Green Revolution that will significantly reduce and drawdown emissions, regenerate nature and help us adapt.
