Loosely hooked to a major UN biodiversity report published last year, which found that the survival of 1 million species was at risk, Extinction: The Facts is a whistle-stop tour of our destruction of nature. A stellar cast of academics and experts from NGOs tell the story of a decline in mammals, plants and fish that Attenborough says “isn’t just disturbing, it’s deeply tragic”.
The big drivers of this devastation are ticked off: habitat loss, climate change and the “escalator to extinction” as species try to adapt to higher and cooler homes. The illegal wildlife trade is also covered, accompanied by harrowing footage of ivory, pangolins and more. The effects of long-term exposure to pollutants like polychlorinated biphenyls (PCBs) – which were mostly banned internationally in 1986, but still end up in seas – are seen for orcas off the coast of Scotland, UK. Even less photogenic subjects, such as the organisms we are losing from our soils, get a look in.

"For most of the last 100 years, Californians suppressed fires in forests, resulting in the accumulation of roughly five times more wood fuel debris than existed in forests before Europeans arrived. "

porovnavat tepelnou energii paliv co potrebujou kyslik (tzn vaha spalovane smesi je pak uplne jina) s elektrickou energii v baterkach a dokonce s energii jakou doakze metabolismus dostat z bagety .. to je proste uplne mimo

Polish oil firm signs up to 2050 climate neutrality goal – EURACTIV.com
https://www.euractiv.com/...vironment/news/polish-oil-firm-signs-up-to-2050-climate-neutrality-goal/

PKN Orlen, Poland’s largest oil refiner and retailer, this week became the first oil company in central Europe to commit to climate neutrality by 2050, with plans to invest billions in energy efficiency, solar, wind, and hydrogen.

Orlen vlastni Benzinu - nejvetsi sit pump v Cesku. Polaci fakt jedou - spocetli si dobre, ze nema smysl jit proti zbytku EU, ale ze je lepsi to vzit jako prilezitost, jak uspet na nove se formujicim trhu s cistou energii.

Za me super, protoze Cesi se radi nad Polaky povysuji, ale pokud pujde vse dal tak, jak je ted, tak brzy bude fakt tezke v Cesku obhajovat to, ze zatimco jim se dari, nam zbyvaji jen zastarale ideologicke floskule...

Fakt je, že prostě nevím, proč musíme pálit nejvíc uhlí na osobu v EU

oregon mi pripomnel fotku co jsem v zime davala k australii...

XCHAOS: mohl bys svoje tvrzeni nejak podlozit? protoze je to opak toho, co ctu...

co se tyka platiny, to je o technologii
https://phys.org/news/2020-05-platinum-free-catalysts-cheaper-hydrogen-fuel.html

co se tyka objemu, ja nechci v patek v noci delat chemickou resersi, ale kdyz mas sportaka na 1600km ve vodiku, kterej jezdi 355km
https://evcentral.com.au/hyperion-xp-1-355km-h-1600km-hydrogen-hypercar-revealed/

a o chlup vetsi teslu na baterky s dojezdem 500km a omezovacem rychlosti, protoze by se baterie vyjela za 100km na plnej plyn, tak to neco vypovida o hustote energie a jejim skladovani.

je potreba si uvedomit, ze jsme sice vodik pouzivali uz pred 100 lety, ale tehda nebyl internet (vic hlav vzdycky vic vi), startup incubatory, klimaticka krize, levna ropa a tak obrovskej objem investic do alternativ. u vodiku jsme teprve na zacatku cesty...

taky se nesmis fixovat jen na elektrolyzu, ale treba vodik misto skladkovani:

The CHANNEL (Development of the most Cost-efficient Hydrogen production unit based on AnioN exchange membrane ELectrolysis) project will run until December 2022. It aims to develop a low-cost and efficient electrolyser unit utilising “non-PGM electrocatalysts, porous transport layers, current collectors, bi-polar plates, state-of-the-art anion exchange membranes and ionomers,” as noted on the project website. “This will enable the development of an electrolyser technology at a capital cost (CAPEX) equal or below classical alkaline electrolysis. However, in contrast to the alkaline technology, the CHANNEL AEM electrolyser will have an efficiency and current density operation close to the one of proton exchange membrane electrolyser (PEMWE).” The project website also states: “The CHANNEL stack will not only result in decreased electrolyser part count, but it will also be able to operate at differential pressure, as well as under dynamic operation, optimal for producing high quality, low cost hydrogen from renewable energy sources.”
