Use videoconferencing with moderation It has become increasingly frequent during the pandemic to use the smartworking through videoconferencing platforms that allow to cancel distances, avoiding exposure to the virus and wasting of time; but staying in front of a video for hours is stressful and often forces an incorrect posture, then can be confused by looking at different faces in the case of multiconferencing without considering that video links consume a lot of energy in the servers (sometimes much depends on the resolution of the images and their size). Also evident is the so-called "digital divide" and many complain of poorly stable, slow connections that put a strain on the nervous system especially in hours of intense internet traffic; so it may be advisable to return to using lighter videoless communication programs that exploit less resources and with less stress. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Feb 27, 2021

 Excessive dependence on semiconductors The difficulties of the global market in supplying semiconductors have recently shown how much it can affect the production of goods, especially in certain sectors, such as the final assembly of various vehicles for the transport of people and goods. Only ten of the world's semiconductors are produced in Europe and electronic cards are increasingly needed to function properly of these microprocessor-governed components. Another problem (on the contrary) is that of disturbing intrusiveness in the life of so-called artificial intelligence and sometimes it is enough to do a search on the web to notice the continuous tracking. It should be noted by changing the subject but remaining on technological issues that a management water treatment computer in Florida has suffered an hacker attempt attack that could potentially put at risk the health of the inhabitants. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Feb 10, 2021 n°: 4631 Renewable sources in Europe outweigh fossil fuels The data provided on energy from renewable sources, such as the sun and wind, in Europe in 2020 would have reached thirty-eight percent compared to thirty-seven obtained from fossil sources, such as gas and coal. Denmark seems to be at the top of this ranking among European countries with sixty-one percent of its electricity from renewable sources, but there are countries like Slovakia and the Czech Republic with less than five percent. The generation of electricity from coal fell well before the 19-nCoV pandemic caused a decrease in consumption and this trend should remain thanks to the large number of new plants that exploit the installed renewable energy, then we must consider the fall in the prices of these plants that make them decidedly cheaper with positive environmental repercussions since the costs to deal with climate change are one of the main items in the budgets of the states. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 25, 2021 n°: 4617 Green hydrogen to limit emissions In order to be able to use zero-emission hydrogen, for example in industries, transport and energy in general is necessary to produce it in a sustainable way for the environment, with low-impact renewable sources to obtain with the electrolysis of water the "green hydrogen" (the high potential electric current passing into the water with special electrodes split H2O in hydrogen and oxygen); in fact, this energy is often obtained by burning coal and gas so much that in 2017 hydrogen production emitted globally eight hundred and thirty million tons of carbon dioxide into the environment equal to the emissions of Indonesia and the United Kingdom combined. The production of green hydrogen remains very expensive for the time being and there is talk of alternative with the so-called blue hydrogen from natural gas capturing CO2, but many difficulties remain. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Dec 12, 2020 n°: 4582 A computer-designed face shield anti-19-nCoV A simulation would have verified how a face shield normally used to protect itself from droplets exhaled into the air by a person infected with Covid-19 coronavirus manages to block only about thirty percent of them, so Japanese researchers using a supercomputer have improved the design of a thermoplastic visor managing to block about seventy percent of it. This protective device that can also be easily moved to one side to allow to eat covers a large portion of the face and can be useful for those working in bars and restaurants. To report completely changing the subject the japanese authorities proposal to release treated cooling water from the Fukushima nuclear plant into the sea or evaporate as well as other liquid treatment procedures. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Oct 16, 2020 n°: 4533 Double button in toilets unfunctional To save water the drains are often equipped with a double button to allow to choose between an amount of about six liters that empties the entire tank and one of about four liters for urine, but research would have shown that this double mechanism equipped with various leverages often fails or gets dirty resulting in small continuous loss of water flow (which becomes huge if add up the leaks of all installed devices); then apparently many declare that they can not understand what is the right button to press sometimes also because of the pleasant but unfunctional design. If is want to change the toilets mechanism with a double-button should inquire about the functionality and durability of the devices rather than the aesthetics and periodically check that do not lose small streams of water. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Oct 01, 2020 n°: 4520 Passions for air travel and SUV overly polluting In the calculation of the individual climate footprint a study would have identified how people who have a passion for air travel and fast off-road cars - SUV produce twice as much polluting emissions as the rest of humanity, at least according to Swedish researchers who would have monitored how in the twenty-five years from 1990 to 2015 the richest (one percent of the population) produced fifteen percent of the polluting emissions and thus more than twice the seven percent produced by the poorest; then there was a trend of upward emissions in the period from 2010 to 2018 linked to the fashion of having a SUV vehicle. To reach the limits by 2030 in order to contain the greenhouse effect, ten percent of the richest people in the population would have to reduce emissions by about ten times compared to now. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Sep 21, 2020 n°: 4511 Sodium instead of lithium for cheaper batteries One of the obstacles to the widespread spread of electric vehicles is the high cost of lithium-ion batteries, but researchers argue that lithium can be replaced with a similar cheaper alkali metal such as the sodium easy-to-find by being present in salt. Trials with sodium-ion batteries have performed well and do not require use in cells of high environmental impact materials such as for example the cobalt, although it will take longer before being able to switch to large-scale mass production; then problems remain to be overcome such as higher sodium weight, lower yield and slightly lower voltage of batteries. There is theoretical talk of sodium multilayers between two layers of graphene and other ploys to improve a technology much more environmentally friendly than that based on lithium. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Set 03, 2020 n°: 4496 Testing to look for coronavirus in sewers A simple technique for finding traces of genetic material left by the Covid-19 coronavirus in sewers could be useful in monitoring the outbreak so as to check for example whether the virus's containment measures are working for a population and inform health authorities of any new outbreaks in advance. The results of a gastroenterology study showed that coronavirus can be identified in the feces of more than half of the seventy-three patients tested, and in seventeen of them they continued to test positive despite the negativity of the diagnostic test carried out with swab applied in the nose and throat. This new technique (still being tested) could also be useful for signalling a new wave of the epidemic or trace cases that are difficult to detect individually. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jun 01, 2020 n°: 4416 Computer viruses linked to COVID-19 The story of the pandemic caused by the COVID-19 coronavirus with the request of many web users of information is often exploited to infect computers with computer viruses, so in case of uncertainty is appropriate not click on the COVID-19 acronym and do not open sites dedicated to various arguments and behaviors to keep to avoid coronavirus infection; in fact, it seems that in the world there have been increasing links to computer addresses that use this mechanism to redirect to unsecured pages. There are also the sites selling masks at higher prices (also bearing in mind that a surgical mask lasts a few hours and is not hygienic to wear more than once), expensive disinfectants, low-efficacy supplements and other products useless against the virus. Apparently some say that a cyber attack is underway on the Italian organizations that handle the emergency. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Mar 13, 2020 n°: 4344 Technology and publications * The author doesn't assume some kind of responsibility for the bad use of the articles councils (all rights are reserved) |
