Considerations for CO2 capture plants Proposals to install large plants to capture and store carbon dioxide or CCS are multiplying, as is happening in Europe and lately in Indonesia, but some point out that this could simply be a way to avoid reducing polluting emissions, continuing to pollute with fossil fuels instead of switching to renewable energy (now also much cheaper than fossil fuels) while others say that it is an inevitable solution from take to avoid a further rapid worsening of the climate crisis. According to a Norwegian research it is estimated that the market for these plants could quadruple within the next three years and there is talk of storage mainly in liquid form even if it is not clear how much energy is needed for this process and what is the actual utility regarding global warming. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Nov 14, 2022

 Use of technologies not yet understood Quantum science is developing rapidly with the possibility of exploiting "exotic" characteristics such as the so-called entaglement that allows to transfer information (even small particles) from one point to another at a distance, but many experts admit that they do not fully understand the logic on which this new science is based; so the question remains whether it is appropriate to use something that is not well known. Quantum computers could follow the same path as the first expensive computers initially reserved for a few and then transformed into increasingly compact and cheap computers so that now any smartphone has great computing capabilities; needless to say this would completely pave the way for artificial intelligence potentially much superior to human intelligence. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Oct 05, 2022 n°: 5149 Energy supply problems in France After the lighting of some monuments in France was temporarily turned off to cope with the country's peaks in energy demand and concerns about how the available resources will be managed, the authorities would have said that there is no risk of a total blackout this winter although we expect to lower electricity consumption by a small percentage up to a maximum of fifteen percent, in a scenario of gas shortage and intense cold; then compared to other European countries apparently France would be structurally in less difficulty. The planned restart of nuclear power plants, half of which are stopped for maintenance due to corrosion of the reactors, will provide the energy needed to meet the demand (questions remain about whether all safety standards are respected). Only a few days of the so-called energy red alert are expected in which it will be essential to make savings. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Sep 15, 2022 n°: 5132 CO2 capture considerations A large CCS plant under construction off the Norwegian coast in cavities in the North Sea seabed will allow to capture in liquid form tons of carbon dioxide produced by Norway (the largest producer in the west Europe) and European factories; but some say that this initiative could allow fossil fuel companies a slower transition to renewable energy, then safety problems remain for example in the event of tidal waves. The CCS plants currently in operation in the world are few and there are cases of closure due to excessive economic costs and operating defects despite the large public funding allocated for their construction and maintenance. To be noted by changing the subject but remaining on technological issues the intention of France to reactivate the atomic reactors in maintenance for corrosion to cope with energy shortages. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Sep 05, 2022 n°: 5123 Damaged Zaporizhzhia nuclear power plant International atomic energy inspectors sent to check the proper functioning of the Zaporizhzhia nuclear power plant in the crosshairs of fighting in the conflict in Ukraine would have declared that it is damaged and are willing to remain in the plant to monitor it; in fact, even making a small mistake could have consequences for decades, then in the meantime one of the six reactors (unit five) of the large plant was shut down for emergency protection. Previously there was talk of a power line interrupted by the conflict and repaired before it could cause damage to the plant. As is well known atomic technology to obtain energy is very risky and a reactor cannot be turned off with a switch in addition to the difficulty of safely storing the waste produced by a plant that remains radioactive even for centuries. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Sep 02, 2022 n°: 5121 Solutions to cope with drought in the world There are many countries in the world struggling with the problems caused to crops by prolonged drought so much so that in China, for example clouds are "seeding" in order to cause rainfall, a technique defined as not very effective as well as perhaps producing chain reactions on the climate on a global scale that are difficult to predict; so better solutions should be found. Some say to recover the wastewater by purifying it especially in coastal areas that would end up in the sea, then could capture the humidity of the air with nets (or technological systems), a technique used in South America on foggy days that makes the drops of water fall into containers; then could use desalinators with renewable energy considering that they consume a lot of electricity and recovering the salt not dispersing in the environment. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Aug 23, 2022 n°: 5112 Quantum computers close to commercialization It might seem an advantage to have computers with computing capabilities that were once unthinkable, but the danger that machines could take the place of man is getting closer and closer and this is already partly the case with current technologies. In practice quantum computers to solve a complex calculation can exploit any electronic routes at the same time instead of having to travel a single route at a time with an exponential speed gain and therefore a calculation that would take nine thousand years with the most powerful supercomputer available with a quantum computer takes less than a second. In addition to using one and zero for calculations quantum computers also use the qubits, any value between zero and one (quite exotic concept) and therefore for example they can solve a very complex mathematical problem very quickly. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Aug 17, 2022 n°: 5107 Nuclear technology too dangerous International atomic energy control authorities say that it is difficult to ensure proper operation of the large Zaporizhzhia nuclear power plant in Ukraine since the control of the plant is not entirely carried out by specific personnel. This consideration could in theory be applied to any atomic plant that is located in conflict areas highlighting how dangerous this technology based on the splitting of the atom is, without considering that the waste produced by the power plants constitutes a danger for centuries. Hiroshima in Japan commemorates the seventy-seventh anniversary of the release on the city of the first atomic bomb followed three days later by another bomb on the city of Nagasaki, with calls for disarmament in a historical moment that still sees the planet at risk of a global atomic conflict. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Aug 06, 2022 n°: 5099 Often inadequate weather forecast templates Making accurate weather forecasts is difficult with climate change also because the weather models on which they are based are inadequate despite the use of sophisticated computers, at least according to the opinion of researchers who have analyzed some situations such as the disastrous flood that affected the Yellowstone park in mid-June and the strong heat wave in British Columbia last year in Canada (country now hit by several tornadoes), noting the lack of reliability of the forecasts that had been made at the time. In practice the history of meteorological events should be rewritten; in fact, even if the software is updated with the various extreme phenomena that happen more and more frequently, they still fail to predict them with obvious safety dangers for the people concerned. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jul 08, 2022 n°: 5074 Better induction than gas for cooking Induction cooking transfers energy with about eighty-five percent efficiency compared to about thirty-two percent of cooking with gas that tends to disperse heat into the environment, at least according to data provided by energy certification organizations that say that induction is also five to ten percent more efficient than the traditional plate with electric resistance; so to save energy it is advisable to prefer induction cooking, but people who wear pacemakers and insulin pumps should keep a certain distance from the magnetic fields generated by induction. For gas cooking then there are also problems related to pollution and contaminants that are released into the environment during combustion (if it is incomplete carbon monoxide is produced) with a negative impact on the health especially of people with asthma. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: May 10, 2022 n°: 5022 Technology and publications * The author doesn't assume some kind of responsibility for the bad use of the articles councils (all rights are reserved) |
