    GLOBETROTTER: Ja se na to koukam takhle: Neexistuje zadny jednoduchy reseni. Bohuzel. Pro nektery je to nesnesitelna predstava a radsi strkaj hlavu do pisku a bud predstiraj, ze problem neexistuje nebo se upinaj k jednoduchejm pseudoresenim (dam si solar na strechu a jsem OK). Podle me jsme v extremne slozity situaci, jejiz reseni nam zabere strasne inteligence, prace, casu a zdroju. A dost mozna se ji vyresit nepodari a dusledky budou strasny.

    Nicmene nejaky souhrn moznych reseni je treba tu v (CJ)

    "Five years ago, members of the Rockefeller family walked away from the fossil fuels that made them rich, alarmed that burning oil and gas was causing climate change. Now it also seems like a smart financial move. The $1.1 billion Rockefeller Brothers Fund — largely free of oil and gas — has outpaced financial benchmarks, defying predictions of money managers."

    Jeste k Planet of Humans:

    Here are some questions that the film raises, and my answers:
    Are EVs Just as Polluting as Gasoline Vehicles?
    The time-capsule quality of the film is underscored by a scene filmed in Michigan about a decade ago showing an event tied to the rollout of the Chevrolet Volt, a plug-in hybrid vehicle that began production in 2010. The narrator makes the point that the vehicle was powered by a local utility that runs almost completely on coal, as if to say that the environmental benefits of an EV are illusory.
    The film is recycling an old argument: that the use of fossil electricity means electric vehicles have about the same emissions as gasoline vehicles. But researchers have looked closely at this and found that there is a clear emissions benefit of using an EV.
    For example, the Union of Concerned Scientists has found that EVs have lower emissions—including emissions from generating electricity—than typical gasoline models, even in the parts of the United States that still rely the most heavily on fossil fuels for electric power.
    The environmental benefits of EVs will increase as utilities continue to reduce their emissions and as batteries used in the vehicles become more efficient.

    Do Solar Panels Only Last 10 Years?
    Planet of the Humans shows an unidentified man at a solar trade show who says, "Some solar panels are built to last only 10 years, so it's not as if you get this magic free energy."
    I can only guess that this comment is from years ago, when panels were less durable and efficient than they are today. I know of no solar panel on the market today with such a short life span.

    A US utility is to trial a new battery storage technology that promises to deliver the holy grail of a grid based around wind and solar – ultra long storage of up to 150 hours that could revolutionise the way the storage technology is used and deployed.
    Great River Energy – a major non-for-profit energy co-operative based in Minnesota – is teaming with Form Energy, a battery storage technology developer backed by Bill Gates, Australia’s Macquarie Capital, and others, to install a first-of-its-kind demonstration of Form’s unique “aqueous air flow” battery with ultra long storage.
    The battery pilot will be a 1MW/150MWh, grid-connected storage system capable of delivering its rated power of one megawatt continuously for 150 hours, part of a broader plan to retire Great River’s main generator, a 1,151MW coal unit, and replace it with wind and ultimately battery storage and make 95 per cent of its power emissions free.

    Storing wind and solar with new gravity-based system – pv magazine International
    https://www.pv-magazine.com/2020/05/11/storing-wind-and-solar-with-new-gravity-based-system/

    Gravitricity is due to begin construction of its £1 million pilot project in October.

    Scottish start-up Gravitricity has developed a gravity energy storage system it says is perfect for storing solar and wind power.

    A 16m-high rig uses the clean power to raise a mass in a 150-1500m shaft and discharges the electricity thus ‘stored’ by releasing the mass to rotate an electric generator.

    Gravitricity said the mass used can range from 500 to 5,000 tons and the electricity discharged could power 30,000 nearby homes for two hours.

    The start-up claimed sophisticated winches and a control system can lower the mass very quickly, making it flexible enough to stabilize electricity networks at 50Hz and ensuring the set-up can respond to full power demand in less than a second. “Our technology has the fast response time of lithium-ion batteries,” the company said

    First Electric Tankers Equipped with Lithium Ion Batteries | Electric Vehicles Research
    https://www.electricvehiclesresearch.com/...rst-electric-tankers-equipped-with-lithium-ion-batteries

    Asahi Tanker has decided to build two world first zero-emission electric propulsion tankers. The specifications of the vessel will use the "e5 tanker" planned and designed by e5 Lab which was jointly established the companies Exeno Yamamizu, MOL, Mitsubishi Corporation and Asahi Tanker and will be completed sequentially from March 2022 to March 2023

    The vessel is a pure battery tanker powered by large-capacity lithium-ion batteries is scheduled to enter Tokyo Bay as a marine fuel supply vessel. Completely electrifying the ship's core energy system will be a move towards achieving zero emissions of CO2 (carbon dioxide), NOx (nitrogen oxide), SOx (sulfur oxide), smoke, etc.

    Photosynthesis rewired to generate hydrogen | Research | Chemistry World
    https://www.chemistryworld.com/news/photosynthesis-rewired-to-generate-hydrogen/4011702.article

    Scientists have successfully directed photosynthetic electron flow away from fixing carbon dioxide and towards proton reduction by fusing together photosystem I (PSI) and algal hydrogenase in vivo. Modified algae cells expressing the PSI–hydrogenase chimera produce hydrogen in a light dependent fashion at high rates.


    ...

    Jenny Zhang, an expert in semi-artificial photosynthesis at the University of Cambridge, UK, says that identifying the site on photosystem I where redox enzymes can be fused is an exciting step forward. ‘This will no doubt form the foundation of future efforts to develop algal systems that can efficiently perform a range of solar-driven chemical formation processes, such as the conversion of carbon dioxide into useful feedstocks. The development of such breakthrough systems are still greatly needed in our repertoire of energy production and carbon dioxide recycling strategies.’

    ...

    We are now moving towards trying to find hydrogenase enzymes that are more oxygen-resistant,’ says Redding. ‘The hope is that by using directed evolution, we could force the algae cells to do all this in the presence of oxygen, so that in order to live, they would have to make hydrogen.’

    TUHO: dost podobně i Monbiot:
    Planet of the Humans, whose executive producer and promoter is Michael Moore, has now been watched 6 million times on YouTube. The film does not deny climate science. But it promotes the discredited myths that deniers have used for years to justify their position. It claims that environmentalism is a self-seeking scam, doing immense harm to the living world while enriching a group of con artists. This has long been the most effective means by which denial – most of which has been funded by the fossil fuel industry – has been spread. Everyone hates a scammer.

    And yes, there are scammers. There are real issues and real conflicts to be explored in seeking to prevent the collapse of our life support systems. But they are handled so clumsily and incoherently by this film that watching it is like watching someone starting a drunken brawl over a spilled pint, then lamping his friends when they try to restrain him. It stumbles so blindly into toxic issues that Michael Moore, former champion of the underdog, unwittingly aligns himself with white supremacists and the extreme right.

    ... the film’s attacks on solar and wind power rely on a series of blatant falsehoods. It claims that, in producing electricity from renewables, “You use more fossil fuels to do this than you’re getting benefit from it. You would have been better off just burning fossil fuels in the first place”. This is flat wrong. On average, a solar panel generates 26 units of solar energy for every unit of fossil energy required to build and install it. For wind turbines the ratio is 44 to 1.

    But this is by no means the worst of it. The film offers only one concrete solution to our predicament: the most toxic of all possible answers. “We really have got to start dealing with the issue of population … without seeing some sort of major die off in population, there’s no turning back.”

    Yes, population growth does contribute to the pressures on the natural world. But while the global population is rising by 1% a year, consumption, until the pandemic, was rising at a steady 3%. High consumption is concentrated in countries where population growth is low. Where population growth is highest, consumption tends to be extremely low. Almost all the growth in numbers is in poor countries largely inhabited by black and brown people. When very rich people, such as Michael Moore and Jeff Gibbs, point to this issue without the necessary caveats, they are saying, in effect, “it’s not us consuming, it’s Them breeding.” It’s not hard to see why the alt-right loves this film.

    Population is where you go when you haven’t thought it through. Population is where you go when you don’t have the guts to face the structural, systemic causes of our predicament: inequality, oligarchic power, capitalism.
