    SHEFIK: to "regenerativni" proste neni nic existujiciho, to je nejaka aspirace. nemuzeme zkiumat regenerativni oraktiky ve smysku ze je ti neco ci existuje a my to ted zaevidujeme udelame statistiku a na zaklade toho dotacni programy. samozrejme, ze to fungovat nebude, to jediny co muze fjngovat je vypracovat v prubehu casu dostatecne komplexni pojem regenerativity (ekosystemu) a stabilizace (klimatu) a v tom ramci se ucit operovat.

    je extremne nepravdepodobny, ze to bude fungovat na prvni druhou a treti dobrou. pokud se to naucime zacit delat v nekakejch oblastech cca do pulky stoleti, tak ta druha polovina stoleti muze byt ve jmenu ty regenerativity. to by bylo fajn, pral bych si to :)

    klima / covid / non-stationarity

    How to prepare for unpredictable climate events to ensure water sustainability | ORF
    https://www.orfonline.org/...k/how-prepare-unpredictable-climate-events-ensure-water-sustainability/

    “Stationarity” is a concept borrowed from statistics. A non-technical definition of the term is that the past is a poor predictor of the future. Globally, all of us for centuries, probably millennia, have assumed that the past can guide us safely in how we prepare for the future. The best engineers and economists in the world assume stationarity. Farmers, builders, and foresters assume stationarity. Most of us in our daily lives too assume that tomorrow will not be that different than today. Climate change is a spirit mocking stationarity.

    Climate shifts in monsoon patterns, cyclone intensity, and drought frequency are no longer easy to predict. The Danish city of Copenhagen had an intense rain event that caused several billion euros in damage in a matter of minutes. And then had another intense rain event about as bad a few years later. The valley where I live on the Pacific Coast of North America is not supposed to have forest fires, but a freak shift in the jet stream over the ocean last September created a flash drought, and within hours we had intense fires and fierce winds channeled through wooded canyons, with millions of people under evacuation orders and thousands of people huddled in evacuation centres during the pandemic to escape the choking smoke-thickened atmosphere.

    Australia faced even more intense fires just a year ago — fires so intense they sterilised the soil, re-engineering whole ecosystems in a matter of hours. These events could be predicted, but they could not be predicted on the basis of what has happened in the past. They were non-stationary events. Indeed, the pandemic itself — while not caused by climate change — is at once a wonderful and horrible example of a radical non-stationary occurrence.

Otevrit novy loziska je problem kvuli ekologii zp, krerou vsichni hajime. Zasoby jsou, nejsou loziska. Neni v tom mafie, ne u nas. Je to cesky vepro knedli zelo.

    Mne to, ciste akademicky, vychazi takto: mejme metropoli s 5 mil. obyvatel (nejblizssi je asi Mnichov, Viden nebo Varsava, tedy jejich metropolitni oblasti) s prirustkem obyvatel dynamickeho mesta, tj. 2 % za rok. Kazdy jeden rok, se do metropolitni oblasti pristehuje na 100 000 lidi za jediny rok. To je srovnatelne s vybudovanim ekvivalentu Hradce kralove nebo Pardubic za rok, znova. Kdyz by byl rust 5 % tak uz se bavime o 250 000 lidi za rok.
    No a kdyz uz mas takovyto potencial na prusery, rok za rokem, tak se to ve stredni Evrope, jak si myslis, obejde bez mafianskych praktik.

    TADEAS: takhle se ale bude efekt multiplikovat.

    a pevne verim, ze agrofertum apod. porad o jidlo jde, da se zpenezit.

    s pudou si iluze nedelam

    kdyz ale zacnes dotovat koncept "regenerace", pak je vlastne nejjednodussi nechat pudu lezet ladem a prodavat odpustky korporacim

    tohle by mely bejt spis zakony jak nakladat s pudou a bejt nakym zpusobem kompenzovany, ale pri kontrole kvality. ne bez kontroly a dotovany korporaci, ktera pak nema uz vubec zadnou motivaci bejt uhlikove neutralni, kdyz se akorat vykoupi.. efekt by byl spis presne opacnej

    Towards a new socio-ecological contract

    Event by European Trade Union Institute - ETUI

    3. 2. v 13:00 UTC+01 až 5. 2. v 13:00 UTC+01

    ➡️ etui.org/Z4Z

    The need to effectively tackle global warming puts under pressure the existing industrial relations models in Europe. A new logic of sustainability needs to be incorporated into the social contracts in order to (re)build harmonious labour relations. A viable world of labour requires a new sustainability paradigm, which encompasses all three of its dimensions: economic, social and environmental.

    Achieving economic sustainability (within the planetary boundaries) has become more challenging. Actual economic growth has come at a critically high cost in terms of inequality of opportunities and outcomes, planetary resources, biodiversity and environmental degradation, thus undermining both social and environmental sustainability. Social sustainability is also likely to come under increasing pressure from the impending fourth industrial revolution. In turn, widening inequality and climate change are forcing us to question the way we measure prosperity and wellbeing.
    The magnitude of the required paradigm shift to ensure economic, social and environmental sustainability implies large-scale economic and societal change and serious deliberation. All workers need to be actively involved in a just transition and nobody should be left behind. Massive societal coalitions will have to be built for a shared vision to emerge and for the just transition, with fairly distributed costs, to be supported. But this is also an opportunity to redefine what we consider to be our societal goals and how they relate to the current focus on (green) growth.
    The next ETUI-ETUC conference will pursue different lines of inquiry and discussion, seeking to understand not only the challenges before us but also to identify what we can do today and tomorrow in order to establish a new social, economic and environmental contract. What targets or objectives should be set, and how might they be reached? How can we create a sustainable European growth model? How can we reverse the trend towards growing inequalities? What kind of Green New Deal is a realistic and feasible prospect for Europe? What elements of justice, solidarity and equity constitute a fair and sustainable social foundation? What are the roles of the market, the state, industry and civil society? And what role can trade unions play to build a sustainable future that addresses all of these dimensions?
    The conference will be online. In order to receive the instructions on how to join please register.

    YMLADRIS: jeden velkej experiment s nejistym vysledkem

    ale chapu to tak, ze samotnej experiment by ani nevadil, spis je problem to, ze to "neovereny" ukladani uhliku bez moznosti dlouhodoby kontroly kolik se uklada, jak hluboko a na jak dlouho se bude automaticky penezit v kreditech, ktery se budou prodavat firmam, co co2 vypoustej.

    to by byl krasne regulaci pokrivenej trh. velky firmy si budou kupovat odpustky, aby nemusely nic menit a farmari budou bohatnout na kreditech. o pudu a jidlo na ni vypestovanym jim pujde az v druhy rade :) ...doplnej to vetrnou elektrarnou a solarem a z farmaru se stane horni trida. zbytek sveta bude jist konzervy ze sklepa

    uzasny, co lidi vymysli pro zachranu sveta.

    a pak jeden z asi nejdulezitejsich odstavcu zaverem:

    A final reason to slow down the carbon farming train is that any carbon captured in the soil would be released back into the atmosphere if the soil were subsequently disturbed. This is important, because the vast majority of farmers who currently practice no-till farming still plow up their soils at least every few years. Craig Cox from the Environmental Working Group has thus asked the key question: “If the practices disappear are the credits refunded?”

    #pochyby

    In May 2020, the World Resources Institute concluded that regenerative methods overall were good for soil health, but the “limited scientific understanding of what keeps soil carbon sequestered” results in “uncertainty about whether regenerative practices actually sequester extra carbon.”

    SEJDA: sam ses pohrebiste, twl vem si prasek.
    Neznam zadnej solidni produkt ve stavebnictvi, kterej by se prezentoval stylem, ze je nekde mafie. Tohle proste na zadnym prospektu nezminis a veletrhu neuvidis, pokud se nechces posunout ze stredu na uplnej okraj.
    Ja jak te pozoruju, a mnohe dalsi, s komercni sferou nemate zadny zkusenosti, jste nejspis akademici a nechapete, jak funguje kapitalismus. Ochrana investic a porcovani bussinesu je vyssi divci, na to ubreceny levicaci nestaci a ruda revoluce neni cesta.
    Nicmene kapitalismus a kriminalita jsou dve ruzny veci.

    OMNIHASH: ve skutečnosti se za ta léta vynořila čísla, která jsem před 10 lety neměl, a která potvrdila, že jsem měl pravdu :-) ale tady je to offtopic, více u mě v [ Solární letadla a vzducholodi (pilotovaná/bezpilotní+stratosférické/elektrické létání+"létající auta"/VTOL) ] ... i když poslední dobou nemám moc čas tyhle myšlenky rozvíjet a vymýšlím spíš nákladní tramvaje do města, na základě reálné zkušenosti s prací cyklokurýra...

    SHEFIK: já to počítal, a i pro dnešní kapacity baterií se s 1/3 hmotnosti v bateriích dostaneš tak do 7000m a nad touhle hranicí zase jsi zaručeně nad hranicí mraků a můžeš už pokračovat na Slunce.... trik je nedimenzovat to na celonoční výdrž a dobíjení na letu (na rozdíl od těch komunikačních pseudosatelitů, u kterých je to hlavní požadavek)

    v tomhle klubu je to offtopic, ale myšlenka mj. je, že solárně-elektrický systém s elektromotorem je řádově jednodušší a levnější stroj, než proudový letoun... tedy bude jich v provozu více, ale uvezou méně lidí najednou. Nebudou vyžadovat tak obří letiště jako proudová letadla, apod. ... ústup od proudových dopravních letadel by nemusel být žádný návrat do 18.století, stačila by určitá změna životního styly.. cesty by byly o něco pomalejší, srovnatelné s rychlovlakem, ale zato bez jetlagu...

    TADEAS: "stores 3x the enegy of powerwall" ... he heheheh heh:

    "Batteries store and release energy with minimal losses; for every kilowatt-hour your rooftop array generates and sticks into a battery, you'll get back more than 90 percent of it. But the process of generating hydrogen by electrolysis using a proton exchange membrane is only about 80 percent efficient, so you lose 20 percent straight away. And at the other end, you'll lose somewhere around half of what you've got stored in the process of converting the hydrogen back into energy through a fuel cell."

    taky by me celkem zajimala maintenance price nebo ta membrana uvniotr vydrzi tech 30 let?

    - Mechanical degradation is usually the cause of early failures of the membrane due to the formation of cracks,tears or pinholes.
    - Chemical degradation can be defined as ionomer damage and loss in PEM functionality and integrity resulting from a chemical attack initiated by the active oxygen species.
    - Thermal degradation can be defined as the change in the membrane characteristics due to thermal variations. Events such as high temperature, subfreezing tempera-tures and temperature cycling are harmful to the membrane. - tohle v dome snad nebude tak horky

    XCHAOS: mozna jako taxi/vtol ve meste na kratky vzdalenosti si to umim predstavit a rika se, ze je potreba 400kwh/kg, ale myslim ze vaha baterek X energie dostat se do stratosfery a to jeste v rozumnym case pro pasazera na zaoceanskym letu bude nejspis o necem jinym... ale uvidime, treba ty kapacity baterek opravdu porostou rychle

    imho mezitim spis dojde k vyrobe leteckejch paliv z co2, na to staci jen prebytek energie. linky nedavno probehly..

    repka mi taky moc smysl nedava, spis sem chtel nasdilet, ze uz i trumup chranenec meni smer :)
