Abych nebyl jen negativni: trochu ted studuju baterie a moc se mi libi flow (proudove?) baterky: http://www.hybrid.cz/prutokove-baterie-pred-prahem-singularity-cast-1 . Redflow slibuje vylepseny design pro ZBM3 baterku https://reneweconomy.com.au/...t-covid-hopes-on-gen-3-battery-and-a-market-beyond-lithium-ion-69265/, ktery by mel byt o 30% levnejsi nez ZBM2, ktera stoji asi $8000 pri kapacite 10kwh a zivotnosti 10let (nejmene), coz by odpovidalo cene asi 4kc/kWh, coz uz je porovnatelne s LiPO4. Pokud by to opravdu dokazali takto zlevnit, tak by to byla pecka - flow baterie jsou bezpecnejsi (nehori) a lepe recyklovatelne. Taky je lze vybijet nadoraz. 10kWh uz by stacilo pri bezne spotrebe domacnosti na 2-3 dny, takze by to docela slusne pokryvalo i nejake neprizne pocasi. No uvidime:)

GOJATLA: Zadarmo nic nikdy neni. Aby se ta infrastruktura na tekuta paliva zaplatila, musela by bezet vice vytizena, nez jen v obdobi letnich prebytku. Ekonomicky to tak dava smysl pouze pri napojeni na offshore elektrarny a/nebo v soucinnosti s nejakym velkym stacionarnim zdrojem - v podstate jediny mozny je jadro.

Internetem v posledních dnech kolují fotky ze San Francisca, kde se vlivem lesních požárů obloha změnila z modré na oranžovou. Opravdu to na místě vypadá jako na fotkách?

Ano. A není to záležitost jen několika posledních dní. Požáry tady začaly už někdy na začátku srpna, což všechny strašně překvapilo. Lidé se totiž připravují hlavně na podzim, protože nejhorší to bývá v říjnu a listopadu. Všechny nás šokoval také rozsah požárů, protože je to všude okolo a v těsné blízkosti města.

Nejhorší situace byla teď v úterý, kdy jsem se vzbudila a ze závěsů na mě prosvítala oranžová barva. Vůbec jsem nechápala, co se děje. Připadalo mi to trochu jako pouštní bouře, kterou jsem zažila jednou v Tel Avivu. Vzduch byl relativně dobrý, protože znečištění se drželo hodně nahoře, jen celý den byla tma. Ve středu ale kouř spadl dolů a kvalita ovzduší začala být hrozná.

Co se týče vzduchu, tak hodně záleží na tom, odkud fouká vítr. Když od oceánu, tak je to dobré, protože většinu kouře rozfouká. Když od jihu nebo severu, tak je to hodně špatné. Nyní se to zase začíná zhoršovat. Před chvílí jsme byli v obchodě a auta jsou úplně posetá popelem. A nedá se pořádně dýchat.

Moria migrants: Fire destroys Greek camp leaving 13,000 without shelter
https://www.bbc.com/news/world-europe-54082201

Police blocked roads from the camp to prevent migrants entering nearby towns.

Many attempted to carry their belongings to the port town of Mytilene but access was cordoned off. Reports suggest many slept in fields after the fire.

Some locals reportedly attacked and prevented migrants from passing through a nearby village after they fled the flames.

"We don't know where to go, and all the refugees are outside, and trying to find a place to at least just stay," he said.

SHEFIK: jo, no to zato my jsme pašáci, my snižujeme spotřební daň na naftu :-)

"vodíkové ekonomice" ve smyslu těch vlaků a náklaďáků - teda moc nevěřím, tam prostě převládnou baterie, i kvůli rekuperaci. Ale stacionární úložiště vodíku asi smysl dává, je to v podstatě jediné sezónní úložiště, které umíme (je tam spousta odpadního tepla, z těch palivových článků, takže by to dávalo smysl jako náhrada uhelných elektráren, s využitím existujících teplovodů)

Wildfires blazed along the Arctic Circle this summer, incinerating tundra, blanketing Siberian cities in smoke and capping the second extraordinary fire season in a row. By the time the fire season waned at the end of last month, the blazes had emitted a record 244 megatonnes of carbon dioxide — that’s 35% more than last year, which also set records. One culprit, scientists say, could be peatlands that are burning as the top of the world melts.

Peatlands are carbon-rich soils that accumulate as waterlogged plants slowly decay, sometimes over thousands of years. They are the most carbon-dense ecosystems on Earth; a typical northern peatland packs in roughly ten times as much carbon as a boreal forest. When peat burns, it releases its ancient carbon to the atmosphere, adding to the heat-trapping gases that cause climate change.

Global Safety Net
https://www.globalsafetynet.app/

The first global-scale analysis of land areas requiring protection to solve the twin crises of biodiversity loss and climate change.

...

More than two years in development, the Global Safety Net is the first comprehensive global-scale analysis of terrestrial areas essential for biodiversity and climate resilience, totaling 50.4% of the Earth's land. The report was published in Science Advances and highlights the importance of protecting and restoring the natural world to address three converging crises -- climate change, the loss of biodiversity, and the emergence of novel viruses such as COVID-19.

The research team was led by the research organization RESOLVE in collaboration with the University of Minnesota, Arizona State University, and Globaïa, with funding provided by One Earth. The data compiled for the Global Safety Net (GSN1) is available through an interactive web application (GSNapp) developed by One Earth in partnership with Google Earth Engine and the data visualization firm Graphicacy. Users can click on a country, state, or ecoregion to see configurations of biologically important land for each region.

The research effort builds upon an array of global-scale data sets to identify areas that require conservation beyond the 15.1% of land area currently protected. These are compiled into five main layers at a 1 km resolution: Species Rarity Sites, High Biodiversity Areas, Large Mammal Landscapes, Intact Wilderness, and Climate Stabilization Areas.

Why Poland is finally giving up its dirty coal habit - Electrek
https://electrek.co/2020/09/10/why-poland-is-finally-giving-up-its-dirty-coal-habit/amp/

Poland generates a huge 74% of its electricity from coal — second only to Germany in Europe, and it’s the ninth-largest coal producer in the world. It has been the only country in the European Union to refuse to agree to reach net zero by 2050. It claimed it needed more time and money to make the shift.
But its hand has been forced by the rising costs of emissions permits required by the European Union’s cap-and-trade system, the EU’s other increasingly ambitious climate policies, and the pandemic, which caused a fall in the use of power. Reuters reports:

In an update of its energy strategy by 2040, the climate ministry said Poland plans to invest 150 billion zlotys ($40 billion) to build its first nuclear power plants, with 6-9 GW of capacity eventually. The first 1-1.6 GW facility would be up and running by 2033.
It also plans to build 8-11 gigawatts (GW) of offshore wind capacity by 2040 with investment estimated at 130 billion zlotys ($35 billion). The development of renewable and nuclear energy facilities will create 300,000 jobs, it said.

The climate ministry said that coal’s share in electricity production will fall to 37%-56% in 2030 and to 11-28% in 2040, depending on the carbon emission costs.

Compare this to November 2019, when Poland had expected the share of coal at 56%-60% in 2030 and at 28% in 2040.
