World's largest pumped storage power plant fully operational in China
  • Meanwhile the US only increased capacity in pumped hydroelectric by 2.1 Gw between 2010-2022 for a whopping 22 Gw total capacity. Hydroelectric generally hovers about 28% of total renewable energy electricity generation.

    The biggest problem (in the US) has been a lack of investment in new pumped hydroelectric projects not connected to improving existing dam infrastructure. Permitting huge new projects is unattractive but smaller ones in geographically/geologically favorable places like with most of the new sites being planned in California and Arizona will grow in the next 10 years.

  • Illinois Carbon Capture Project Captures Almost No Carbon
  • I completely understand. On a personal level I worked for years on lobbying to get a carbon fee and dividend system passed at state and federal levels because I felt that taxing companies for their carbon emissions was a smart and tangible way of dealing with the problem. As I’ve grown cynical with CF&D never catching on politically, I sniffed out different technocratic solutions. I agree the companies researching and implementing CCS are the same oil companies that got us into this mess so how much can we take from their advocacy with CCS as being a good thing? As a professional geologist I have a love-hate relationship with O&G industry but they are so powerful I don’t know how to work against them but instead with them (I don’t work for an oil company, I work in publicly funded CCS research)

  • Illinois Carbon Capture Project Captures Almost No Carbon
  • Not exactly dry ice, it is supercritically pressured carbon dioxide so it has the density of a liquid but defuses like a gas. CO2 plumes are stable at depths where injection occurs because they are maintained in a pressure and temperature environment where the CO2 stays in a liquid stage, so it will never rise to the surface like a conventional lighter-than-air gas. In-situ mineral carbonation can also occur where the CO2 is injected into silicate rock formations to promote carbonate mineral formation, locking the CO2 for thousands (millions maybe) years.

  • Illinois Carbon Capture Project Captures Almost No Carbon
  • This is just simply not true . There is robust science that shows the technology can work, it is not a comprehensive solution, but one of many that can reduce atmospheric CO2 emissions. You can read my post where I cite some literature if you’re interested.

  • Illinois Carbon Capture Project Captures Almost No Carbon
  • Planting more trees and making more solar panels won’t fix the issue of rapidly increasing CO2 emissions around the world. Making solar panels is not a green industry and the ability to build them locally is not really an option for a lot of countries, which will need petroleum fuel to ship panels and mine the materials. CCS is the only technology we have available that can actually prevent CO2 emissions from entering the atmosphere from sites that are CO2-heavy, with direct air capture showing we can remove carbon from the air (though it is not inefficient). Yes, that CO2 is instead going into the deep subsurface (mineralized or as a supercritical plume) but it can be managed with robust regulations and scientific monitoring. Petroleum based combustion is not going away and especially in an incoming Trump administration I see any option on the table as a good one when it comes to carbon wrangling. I’m happy to debate this because as a society we need to have dialogue about how to mitigate climate change.

    Regarding this Illinois project, this project began 10 years ago as a proof of concept, of course target sequestration rates will be lower than desired. DOE regularly invests huge sums of money to develop technology for industry using research scale pilots. This plant was never meant to be a proof of what large-scale CCS can do.

  • Apple to pay $95 million to settle lawsuit accusing Siri of eavesdropping
  • I was talking to my brother in law about this. His position approximates this article. While I agree this may not be intentional spying (never proven in court ) on Apple’s part they at a minimum did not account for this huge engineering problem on the back end where Siri couldn’t decipher between key words and background noise. Maybe don’t push products that aren’t robust? Especially since this law suit started in 2019 when voice tech was still (still is) in an infancy.

  • Date Change
  • The Paleozoic era ended with the P-T extinction - the Great Dying - when about 80-90% of marine life died, but more marginal survival rates were found on land. Dycodont therapsids (two tusked proto-mammals with reptile body plan and leg splay) , predatory amphibians, and diapsid reptiles (reptiles with advantageous openings on the skull, all modern birds and crocs have this for example) all survived to varying degrees. Into the Mesozoic reptiles would continue to adapt to a rebounding ocean seen in species such as ichthyosaur. On land, conifer trees began to take hold and mosquitoes evolved to become a pest for the next 230 million years.

    This is all to say we don’t really know what any of these guys looked like, maybe like how this comic portrays, checks don’t fossilize unfortunately.

  • What successful or popular movie that many loved you just HATE?
  • I think you hit the nail on the head answering OP’s question, sorry you didn’t like it! To be fair it wasn’t popular when it came out and became a cult classic in the 00s. I think it captures an absurdist side of America of the 90s (not to mention starring Buscemi, one of my favorite actors)… bowling alleys for social meet ups, roughneck Vietnam vets, drug-slipping Porn kingpins. I watch it maybe a couple times a year when I have a hankering for a White Russian :)

  • Prayers and tears mark 20 years since the Indian Ocean tsunami that killed some 230,000 people
  • I was a youngling when this happened but rereading about this event 20 years later… we’ve seen nothing like it. I think the most interesting fact from this earthquake/tsunami is that the Indian Ocean’s volume permanently decreased as a result of sea floor movement, producing a rise in the global sea level by an estimated 0.1 mm.

    This event also improved tsunami warning systems throughout the Indian Ocean and Indonesia, hopefully if an event like this happens there will be a lot more notice given.

  • Steamy
  • I don’t see the argument you’re making. Science across all disciplines is complex. The more a person attempts to understand and define an object or a phenomenon it opens more doors to more questions about it’s nature. Classification is inherent to our human minds understanding the world around us.

  • What is contained within the hot moisture clouds emitted by hot springs?
  • Hot springs are the surface manifestation of subsurface groundwater being indirectly heated by geothermal heat, usually magma (magma is underground lava, lava is magma erupted at the surface). Environments where hot springs occur are associated with their eruptive counterparts called a geyser. Subsurface rock with fractures and wide pore space between grains are more conducive to the geostructual plumbing that characterize hot springs/geysers. More acidic and biologically active hot springs are called mudpots. The groundwater will reflect the environment it circulates in and can have wide range of dissolved ions. Once vaporized or brought to the surface groundwater and mobilize any number of compounds. Most geysers are coated in Geyserite, which is a hydrated silica mineral sourced from silica rich bedrock that groundwater interacts with. Some environments, called fumaroles, will have no circulating liquid water and will be dominated by volcanic vapor and groundwater steam. Fumaroles are the nasty ones because they tend to have vaporized hydrochloric acid and sulfur oxides in the steam. These emitted gases derive from cooling of complex magmas that contain sulfur, fluorine, hydrogen, and carbon.

  • Tsunami Warning North California 7.3 Earthquake
  • So tsunamis are definitely a threat generally from earthquakes and an earthquake of this size can make it deadly. Unlike the San Andres faults that cause most California earthquakes ( which wouldn’t produce significant tsunamis) this earthquake occurred in a discordant part of the pacific oceanic crust called the Mendocino triple junction - the intersection of the San Andres fault, Cascadian subduction zone (where the Pacific crust is plunging under the North American continent, feeding features like Mt. St Helens), and the Gorda plate (the last remnant of the precursor to the pacific plate, the Panthalassic Ocean that surrounded Pangea).

  • Energy CEO Who Drank Fracking Fluid Is Now Trump’s Oil Evangelist
  • Reminds me of this man, over exactly 100 years ago. To quote:

    On October 30, 1924, Midgley participated in a press conference to demonstrate the apparent safety of tetraethyl lead (TEL), in which he poured TEL over his hands, placed a bottle of the chemical under his nose, and inhaled its vapor for sixty seconds, declaring that he could do this every day without succumbing to any problem.

  • Romania set for right-wing runoff after PM eliminated
  • A good point. From the get-go humans have been intensely tribal and fearful of outsiders. 10,000 years of history shows we kinda bumbled our way through it with a lot of causalities but also a lot of beautiful culture, art, feats, and athletic talent sprinkled in for people who had the time. Now every part of the earth is so interconnected it is unprecedented. How we bumble through this stage is unfolding into a sad story but I can’t get too beat up about it for my own sanity.

  • A sample of Moon's far side retrieved by Chang'e-6 implies unique volcanic eruptions 2.8 billion years ago

    Most of Moon, like samples collected from Apollo missions, is composed from an enriched magma source (called KREEP) derived from material formed in the Earth-proto-Moon impact, however this sample shows a geochemical composition related to volcanic eruptions not associated with KREEP

    How long did this volcanism last on the moon?

    Why is this magma source isolated to the far side of the moon?

    Exciting to see the first analysis of these unique samples and their implications in the history of the Moon!
