New recycled, ecological and lighter materials The demand for the search for new materials that derive from the assembly of recycled raw materials and are also ecological and lighter is increasing, for example some have long argued that means of transport could be built by assembling them even in part with recycled plastic materials and composites allowing a good weight saving and therefore energy having to move lighter vehicles, then also various boats recycling fiberglass boats avoiding that plastic materials turn into microplastic polluting the water. Of note changing the subject but remaining on technological issues the first uses of waiter robots that approach a future scenario dominated by machines perhaps equipped with artificial intelligence superior to the human one, developing a dependence on these so that it will no longer be possible to "pull off plug" in a figurative way. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: May 10, 2023

 Increasingly invasive and heavy technology With the advance of the presence of artificial intelligence in everyday use, some complain that there will no longer be room for personal inventiveness and creativity while others say that a computer however advanced as a technology can never for example write a sophisticated text like that devised by a human brain, but this consideration recalls in parallel the statement about the first applications that many years ago allowed computers to play chess that do not never beat to this game the inventiveness and strategy of an expert chess player (everyone knows how it ended). As far as the weight of the technology reference is made to the weight of lithium batteries; in fact, some point out that the increasing use of heavier vehicles raises questions about the durability of bridges, roads, garages (perhaps multi-storey) and various infrastructures. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: May 03, 2023 n°: 5326 Some common goals for solar and wind Seven rich nations would have planned in Sapporo in Japan new common energy targets for solar and wind regarding the achievement of important production quotas, in a faster transition to free themselves from dependence on fossil fuels, defined as significant and at the same time guaranteeing security leaving the possibility in case of need to continue to use for example gas to support sudden strong energy demands and avoid any drop in production in the absence of sun and wind. It has also set 2040 to progressively reduce plastic pollution to zero, a goal to be achieved in a decade, but environmentalists have long pointed out that the demand for plastic around the world would support the production of fossil fuels and that it was necessary to replace it with biodegradable one. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Apr 17, 2023 n°: 5314 Barcode degeneration and augmented reality An innovation that could be useful to identify goods such as the barcode, of which yesterday we remembered fifty years since its appearance on the market (but patented in 1952 and improved with further developments in 1971), is now in many cases replaced by the so-called QR code so much so that some say that its days are numbered since we tend to use the new technology that is often applied almost everywhere even to living organisms and connected to programs called augmented reality that for example explain what is being framed with the smartphone. It is a bit like turning off the brain and relying on the computer as it happens for artificial intelligence that in an even more invasive way completely replaces the human mind in its creative capacity and reasoning opening up scenarios with images seen in science fiction fiction in which only one computer can beat another computer. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Apr 04, 2023 n°: 5303 Controversy about artificial intelligence As already widely verified regarding the consequences of teaching experts strategies to win a game of chess to a computer that have led in the past to the defeat of biological human intelligence against a made of silicon causing questions if we should continue to educate semiconductors, now the controversy against artificial intelligence that learns by itself from what is proposed to it and from the internet with possibilities once unimaginable. Needless to say that decades ago this experimentation on artificial intelligence had to be stopped and now some say that it is too late to try to put a stop to a technology that many have already used for some time, then others say that competitions on the development of these technologies must be taken into account; however in theory could still intervene against this intellectual threat. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Mar 31, 2023 n°: 5300 Considerations on EU energy efficiency The measures established to save energy in Europe for buildings with the aim of building in the coming years all new homes with zero impact and reaching class E of energy efficiency by 2030 for all buildings and class D for 2033 (apart from historical and artistic ones and various derogations) cause some questions; in fact, if on the one hand they allow to reduce dependence on fossil fuels and to limit polluting emissions, on the other it is not clear with which materials to carry out this ecological transition. Putting thick coats almost always made with petroleum derivatives and fixtures with plastic frames on buildings would not seem to be a sustainable choice even considering that these materials will sooner or later have to be disposed of, then not enough research is carried out on ecological materials that allow good efficiency. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Mar 16, 2023 n°: 5286 Difficult transition to expensive electric cars An electric car has a much higher efficiency than that driven by a combustion engine and with much lower polluting emissions if the energy chain for recharging the batteries is clean, therefore suitable for improving the air quality of polluted and unlivable cities (for example in Italy in cities like Turin and Milan the levels of fine particles are alarming); but some argue that they are expensive and not affordable for all budgets, then much of their components are not very sustainable and the extraction and processing of rare metals and chemical components necessary for their assembly takes place in factories around the world very polluting. Europe is far behind other countries in this transition having invested little in the electric car sector and risks being penalized by this transition, in practice without being able to obtain substantial advantages. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Feb 01, 2023 n°: 5249 A laser to guide lightning In the hope of finding a method to protect people from lightning discharge, the researchers would have developed a laser beam to guide them in the desired direction and possibly with future developments to be able to control them. There are over four thousand people in the world who lose their lives for lightning that discharge their power to the ground even forty to one hundred and twenty times per second with considerable damage to the affected structures, then more frequent for the climate change. Benjamin Franklin (Boston 1706 - 1790 Philadelphia) experimented in 1749 with a simple lightning rod still widely used, then did other tests described in the work "Experiments and Observations on Electricity" of 1754. For many years we have been trying to exploit the energy of lightning, but there remain limits on capabilities and how to store such a large power discharged in a very short time. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 17, 2023 n°: 5236 Nuclear fusion and renewable energy After the announcement made in February in England to have carried out a safe and clean nuclear fusion experiment by doubling the energy obtained previously and therefore with progress, obtaining in figurative terms the energy equivalent to boiling sixty liters of water, comes the news from a laboratory in California of a fusion reaction that has produced more energy than that used in this reaction that fuses two hydrogen atoms through lasers in a capsule. It is a chain reaction that is interrupted by turning off the lasers that simulates the energy process used by the Sun and the stars at very high temperatures without polluting (radioactive waste) and producing greenhouse gases, but before a power plant based on this technology is ready it will probably take decades so for the moment it is better to focus on renewable energy. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Dec 13, 2022 n°: 5207 Transition more sustainable to electric vehicles Electric vehicles require for their manufacture many metal parts and many components that must travel from all over the world before being assembled in a supply chain that is not sustainable for the environment, then some say that to extract rare earths from the soil by mining a large amount of climate-changing gases are released into the atmosphere that continue to feed a greenhouse effect that causes abnormal warming of the planet and devastating extreme effects. To power these electric vehicles energy from fossil fuels is often transformed instead of using clean energy from renewable sources; so in practice for example a car with an electric motor could have an overall environmental impact even worse than a traditional one with a combustion engine and in the case of hybrid ones it is necessary to take into account the greater weight of the vehicle due above all to the batteries. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Dec 12, 2022 n°: 5206 Technology and publications * The author doesn't assume some kind of responsibility for the bad use of the articles councils (all rights are reserved) |
