Thanks Richard. Some really interesting assumptions in that story, but the image is just whacky out of all proportion. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

But it allows those with very small minds to wrap their meager brain cells around a very simple, but wrong, principle. Definitely Trump supporter territory there. |

This looks to be a very big win: CO2 Free Steel becomes a reality... And that is in the here and now and at industrial scale. No more need for dirty old coke and coal!! And all for less required energy input overall also! ... How quickly can the rest of the world's steel production be converted to go clean?...

Going further with green hydrogen, we have spearheading new business: JCB signs green hydrogen deal worth billions wrote: Construction equipment maker JCB has signed a deal to buy billions of pounds of green hydrogen, defined as hydrogen produced using renewable energy.

https://www.cnn.com/2021/11/24/us/arctic-ocean-early-warming-climate/index.html The Arctic Ocean has been warming since the onset of the 20th century, decades earlier than instrument observations would suggest, according to new research. |

Likely fits here best here though it isn't explicitly about climate but is about how humans react to solving a shared problem. https://www.bbc.com/worklife/article/20211122-why-overly-kind-and-moral-people-can-rub-you-up-the-wrong-way |

I'm not so sure about this being a real solution as yet, but it's sort of a start and interesting. Newly Invented Catalyst Dramatically Increases The Efficiency of Turning CO2 Into Fuel. It took nature decades of photosynthesis, followed by eons of intense heat and pressure from geological activity to bake atmospheric carbon dioxide into the long chains of hydrocarbon that make up fossil fuels. |

Now if they can get this down pat I can see it going a long way, especially here down under. New Solar Panel Design Uses Wasted Energy to Make Water From Air. While generating green energy, solar panels usually create excess heat that goes unused. But with a new, innovative design, scientists have found a way to harness those precious leftovers to give the power producers a second purpose: pulling water out of thin air.... |

Well, my confusion continues. As some will know I periodically have a look at the UK's electric grid's sources of power, if for no other reason than being nosy. Today, a rather dull day here in the middle of England the mix was: CCGT = 39.4%; Nuclear = 15.3%; Wind = 24.4%; Hydro = 2.4% Solar = 0.4%; Coal = 3.9%; Biomass = 7.4% (Don't bother trying to add this lot up, I know it doesn't add up to 100%, there are quite a few, generally quite small, sources I've not included) Hardly any surprise that solar is so low, we are looking at the UK on a dull March morning and the Sun is hiding behind a thick layer of cloud. The amount of nuclear is fairly constant at just below 6GWHr, but obviously the proportion varies with demand. Hydro, well we are a "green and pleasant land", with no real mountains, but some decent upland areas so I think we could do far better on that front. Wind, well we do have a fairly constant wind flow over parts of the UK, but it does vary a bit too much to be a reliable backbone. Coal??? WTF, I thought we'd got rid of all the coal burners. The UK is pushing solar and wind, but I don't see that being the whole of the UK's energy solution. Quite a number of UK new-build houses and commercial premises are having lots of solar panels fitted, I've no idea about how many of those are feeding directly into the grid and how many are connected to battery banks. But we are in the UK and we do not have the nice bright sun of say North Africa, but a cloudy maritime climate. So why not encourage micro/mini-hydro schemes which would utilize some of the run-off streams around our moors and uplands, reduce the need for massive power distribution networks and not rely on the rarely seen sun, but on the frequently observed rain. I'm sure with a little thought and effort hydro could easily eliminate the need for burning coal, and eat into the CCGT requirement.

I suspect that much of the answer lies in so much of British decision-making being concentrated in the relatively flat, dry, and porous south-east of England. Scotland has a significant number of public hydro-power stations feeding into the national grid; both Scotland and Wales have pumped-storage hydro stations (Cruachan and Dinorwig respectively); England (well, Northumberland) has Cragside, attributed with being fitted with the first private hydro-electric system in the world, in 1870. So we have the knowledge, the expertise, and (in some places) the geography to make use of all these tools. But either we've forgotten how, or we overlook them in favour of more "acceptable", "fashionable" alternatives. |

Richard - of your list of options I'd go for "fashion" as the most likely. Just look at the number of villages that had their own water driven mills at one time. Indeed there were some quite substantial industrial machines like ore crushers and forge hammers that were water powered until the late 1800s, whereupon it became fashionable to use steam the electricity to provide the power for such equipment.

Yes, I live in exactly such a village. Our village symbol is a stylised water-wheel, derived from the wheel at Sunnydale Paper Mill. It's said that the top wheel (of two) was the largest built, until the Laxey wheel was built to a similar design. The mill it powered produced high-quality paper, used for printing banknotes. The mill was the highest and most prestigious of a chain of up to a dozen mills that ran down the valley - so it got first dibs on the water captured from the moorland. Each subsequent mill captured the water again in its own pond, and used it to power mostly textile production. I have a map dated 1899, showing the main mills still in use - it can still be used as a walking guide to the village, and the outlines of the now-demolished buildings can be traced. I live in a small courtyard of five cottages: one of my neighbours when they were first built in the 1850s is listed as a 'papermaker' in the 1861 census. |

Fascinating little bit of local history there Richard. Edit to add:- I'd have never thought of Yorkshire as producing paper. Tea maybe, but paper! Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |
