TailingsPond + 1,006 GE September 19, 2022 On 9/16/2022 at 12:45 PM, specinho said: not too sure if dust particle theory is popular but generally.......... Early in the morning, if the day before was hot but morning after is humid and cooling in the tropics, the sun usually looks red. The theory is............ hot weather dries up dust particles hence, allows dust particles to fly higher up and fly everywhere. Condensation allows particles to settle on cloud or water vapour gathered. The combined density allows only radiation with the longest wavelength to penetrate i.e. infrared ray. And the sun and clouds across it appear reddish. If weather was cooling the day before and cooling morning after, it might mean there would be less dust particles and vapour in the air. The sun appears yellow or orange due to less resistance on ray penetration. And so forth... As water vapour or morning mist evaporated, the sun resumes whitish...... due to its hot burning center. The deduction is hence, thickness of resistance layer in the air, formed by pollutants and water vapour would determine the colour we see........ https://en.wikipedia.org/wiki/Rayleigh_scattering Quote Share this post Link to post Share on other sites

Michael Sanches + 187 September 23, 2022 Fortunately, coal is coming to the rescue of our energy shortages. 104 coal plants of a total of 102 gigawatts (GW) in 26 countries were planned, considered, or in construction under either Chinese financing or engineering, procurement and construction (EPCs) agreements, CREA and its partner in the report, People of Asia for Climate Solutions, said. 7.6 GW or 14 plants, have already entered into operation over the past year. Another 27 plants with 23 GW capacity are near completion, and they will likely enter into operation soon. Quote Share this post Link to post Share on other sites

With Covid still chugging along and a war on it might take a couple years for energy to shake out. Is the drop in Mongolian coal imports a reason China is adding coal?

Hence, the smaller the mass, the smaller the energy? 2. not too sure if you have seen this.... it is a funnel wishing well. They way it functions is when one puts a coin onto it, the coin will roll, encircling the shape before dropping into the hole...... This is when the center is fill with air only. If the speed of coin is fast enough, it will swirl at the same spot for a few round before dropping its speed and roll downward. Hence, I might be wrong that there might be no attraction at the center of the Sun but sere speed of rotation of planets that sustains them on their respective path.... 3. If, when bond form, energy is released. If fusion of hydrogen can be represented as H + H ------> He + energy If fission of uranium can be represented by N + U --------> explosion -----> energy + smaller stable atoms not too sure why am I sensing something is not quite match with fusion..... This is not my field. I barely passed physics. Just a feeling........ 🤗 In fusion reactions generally the hydrogen isotopes of Tritium and Deuterium are used and fused at extremely high temperatures to create a plasma contained in a magnetic field inside a Tokamak. The issues mainly are sustaining the reaction and waste heat. Quantum computing may be able to solve the problem of sustaining the fusion process but thats a few years away in my view. When deuterium and tritium fuse, they create a helium nucleus, which has two protons and two neutrons. The reaction releases an energetic neutron. Fusion power plants would convert energy released from fusion reactions into electricity to power our homes, businesses, and other needs. How do you fuse deuterium and tritium? The most promising of the hydrogen fusion reactions which make up the deuterium cycle is the fusion of deuterium and tritium. The reaction yields 17.6 MeV of energy but to achieve fusion one must penetrate the coulomb barrier with the aid of tunneling, requiring very high temperatures .

However, I never said that the present crisis was the result of renewables as such. It isn't. The problem is the demonisation of coal and gas and so on and the fact that such fuels are impossible to get rid of in any of the time frames proposed has created problems which renewables cannot solve. As for Norway having 100 per cent renewables its all hydro so its no problem. Its a similar story with New Zealand, incidentally, and some smaller places which are all hydro. If you've got hydro on the system then you claim emissions virtue. Otherwise its horribly difficult and/or horrendously expensive. Germany was certainly mis-managed but it is difficult to see how proper management could have changed much. Anyway, we agree on a lot but I'll move on. Thanks for teh discussion. Let's look at how well countries in Europe are able to be using/generating renewable electricity. Even large and wealthy countries like Germany manage more than 40%. Of course you are also interested in final energy share being renewable (that is all energy, not only electricity). Large economies like Spain and Italy are already over 20% renewable. It is not the question anymore "can we go 100% renewable?". The question is "By when are we 100% renewable?" 1 Quote Share this post Link to post Share on other sites

Highlight the essence here........... Imagine the prospects of health care service..... People who need it might usually be a) infants and mothers/ pediatric < 3 years old, b) aged generations/ geriatric > 60 yrs old, c) some unusual cases of genetics, occasional cases etc. Those ages in between might rarely need it because they are usually healthy and vibrant with activities, especially people from not so well off group. If, a + b + c comprise 10% of a population and out of this 10%, only 0.1 to 1% requires regular medical service, and if a population is 300 m, then it would be 300,000 people. Divide that into 50 states............ we get 6000 people per state? Divided that to 4 months to 6 months regular interval, one month would be 1500 people or 50 people per day? And divided that into how many districts equipped with clinics, yes? Question: 1. after so much they have contributed to the economic growth of a country, is it really that hard to provide free care for them? 2. insurance started off as good intention and generosity of some well off pioneers to protect their workers who might be doing injury prone or high risk work. Later, it grows to become making money on customers' expenses. All insurances purchased are like paying money for things you might or might not used once or twice for a life time, with no guaranteed return. Not even an investment linked saving insurance could guarantee your basic seed saving is protected............ Why insist to do it on high prices and why impose? Hence, we can probably deduce that high costs incurred might be due to mismanagement of fund or allocation e.g. wastage on purchases, excessive staff, overpriced purchases etc........... If spending so much on hiring so many to treat so few, why can't we demand good quality of free service? Wondering if there is a crash course teaching government officers the basic?

Mark, just for fun pretend the sun is of little use in the winter. Now pretend wind is great in the winter but can’t be counted on. Now set your grid up for success. Have plenty of nat gas in the winter to run 95% of the grid. Bingo problem solved. Summer solar and wind with batteries are cheaper than nat gas so deal with it. You ain’t stopping it. As batteries and renewables get cheaper even nat gas winter market share will be eaten into. I expect this to be years from now though. That’s how I see it shake out.

Renewables are NOT cheaper than fossil fuel alternatives - esp coal. Firstly you need diverse forms of powergen for a stable grid. Nuclear, renewables, FF, Hydro, Biomass etc etc. Why do you need to sotre electricity when you have a diverse source of electricity generation? In the UK if the wind is blowing (which it does a lot) and we have excess then we simply sell it to our neighbouring countries via 8 interconnectors! Transportation is through the existing grid network like anywhere else! As for cost, How much does it cost to set up a coal power plant? In fact, the estimated costs of building new coal plants have reached $3,500 per kW, without financing costs, and are still expected to increase further. This would mean a cost of well over $2 billion for a new 600 MW coal plant when financing costs are included. https://schlissel-technical.com/docs/reports_35.pdf Wind:- There are economies of scale so larger turbines cost less per kW-installed than smaller ones, and single turbine sites costing more per kW than multiple turbine sites. Having said all of that, a reasonable conservative budget price for the ‘example’ turbines used throughout this webpage would be: Maximum Power Output Typical Turbine Type Project Cost 100 kW Norvento nED100 £405 k 800 kW Enercon E53 £1.03 million 1 MW EWT DW61 £1.25 million 3 MW Enercon E82 £2.33 million 3.5 MW Enercon E126 EP3 £3.13 million For reference, https://www.renewablesfirst.co.uk/windpower/windpower-learning-centre/how-much-does-a-wind-turbine-cost/typically the actual wind turbine costs around 69% of the total project cost.

There are no "huge problems" on the European energy market. The last major blackout was in 2006, way a before solar and wind were installed. So far, the only real problem we have seen are negative electricity prices on the wholesale market. This should reduce/go away once we can store excess production at competitive prices. So is there an actual problem with energy droughts? There are 50-150 hours per year (0.5-1.5%) of solar+wind droughts per geographic region (A Brief Climatology of Dunkelflaute Events over and Surrounding the North and Baltic Sea Areas (tudelft.nl)). However, for geographically distant regions, the correlation between these events is lower than 0.2. (e.g., UK and Finland will not have simultaneous droughts). Hence, HVDC will solve this, potentially supplemented with ramp-up predictable sources like bio, nuclear & hydro. Short duration periods (several hours) can be covered by battery/electrolyzer solutions. The right way of doing this is currently field tested in TNO Keeping the electricity grid stable | TNO. All elements are in place, what is missing is the logic. What is obvious is that we will need to build more energy generation capacity than "just enough", as we do now. That's all.

The remaining 20% should be a blend of multiple technologies including solar, wind, tidal, oil, gas and coal where they make the most sense from and operational and economic perspective. Until renewables have a fundamental change and become economic when required to deliver power 24/7/365 w/ 99.99% uptime, they can't be more than 10-20% of the power gen mix. The fundamental changes in renewables I'm talking about are development of either: 1) cheap, flexible, scalable energy storage or 2) changes that make reliable generation 24/7 possible e.g. solar generation in low Earth orbit where the sun shines 24/7. A kWh of electricity from renewable is 1.5-3x cheaper than one from new nuclear developments. That leaves a lot of money on the table to come up with storage solutions. New onshore wind projects are USD 0.033/kWh, utility-scale solar PV USD 0.048/kWh and offshore wind USD 0.075/kWh. Compare that with the cost of power from e.g., Hinckley Point C : $0.119/kWh. I don't think we are going to see a large increase in nuclear: who is going to invest in that? Quote Share this post Link to post Share on other sites
