    Engineering development to prevent virus outbreak

    I can see little discussions in this section of forum concerning engineering developments to prevent coronavirus to become ubiquitous.

    https://www.who.int/news-room/detail...ew-coronavirus

    I have been in touch with WHO about developments of ventilators for hospitals, hotels, restaurants, etc. I have also suggested to them the development of active air filters consisting of hot electric elements to kill(in fact deactivate) viruses at incoming and outgoing air vents.
    They replied: "Ventilation systems in hospitals, et.al., are always a partcular concern in any similar outbreaks."

    I have also suggested to them some details of a design for a personal hot element active filter design.

    Sugggestion has also been given to scientific and engineering committees for standardization of ventilation systems at outbreaks.

    How much would this kind of active filter reduce coronavirus to become pandemic?

    It seems like there is a dire need for better ventilation systems in Cruise ships.

    The future of engineering. I think Google and the University of Cambridge are going to have a conference on the future of engineering.
    It is the right time to find a good and the best solution.

    Just as a simple question, but isn't that how those hand dryers work? There is a bluish light, and I assume that is UV light that is supposed to kill germs.
    As above, so below

    Never seen one in my neck of the woods, but the blue light is for show the invisible UV can disinfect the interior but not the passing Air. There are hospital versions which can disinfect the air:

    And FWIW the WHO says don't use 'em, mostly to prevent irritation:

    UV lamps should not be used to sterilize hands or other areas of skin as UV radiation can cause skin irritation.
    ETA: From that same web page:

    Hand dryers are not effective in killing the 2019-nCoV. To protect yourself against the new coronavirus, you should frequently clean your hands with an alcohol-based hand rub or wash them with soap and water. Once your hands are cleaned, you should dry them thoroughly by using paper towels or a warm air dryer.

    But are they effective for vents? Are vents even a source of 2019-nCoV as the OP suggests?

    EM auto sanitizing gate
    https://www.telegraph.co.uk/news/0/c...-spread-covid/
    Are these gates effective?
    Two more question:
    1- Is the weight or density of a coronavirus known? The size is said to be 0.4 to 0.5 microns.
    2- How much could these viruses spread in air by the motion of cars?
    I hope engineering developments on coronavirus or virus in general would continue to be discussed in this thread

    Apparently no technical specs are searchable.
    Is this EM AUTO SANITIZING GATE based on UVC?

    There seems little point contact WHO about this. They don't manufacture equipment. You should contact (or start) an engineering company.

    How much would this kind of active filter reduce coronavirus to become pandemic?
    And if you don't know the answer to this, then you probably are not a in a position to propose solutions.

    So far, all the public advice given by WHO and other health agencies have revolved around reducing personal or social contact. The measure of staying six feet/two meters from another person has been specifically cited by many medical and public emergency sources.

    So if that distance is considered enough to protect an individual from infection, I doubt that ventilation systems, which typically have much longer ductwork than two meters, are going to be a major focus for prevention by agencies.

    Global research on coronavirus disease (COVID-19)
    WHO is gathering the latest scientific findings and knowledge on coronavirus disease (COVID-19) and compiling it in a database. We update the database daily from searches of bibliographic databases, hand searches of the table of contents of relevant journals, and the addition of other relevant scientific articles that come to our attention. The entries in the database may not be exhaustive and new research will be added regularly.

    Probably the density of coronavirus is unknown. Strange: answer questions in proportion to your knowledge. I think, at least you could be able to answer this. WHO needs this information

    Please be informed that I requested WHO to request emergency departments in china so that they could request industrial sectors to develop active masks when coronavirous was spreading in China.

    UVC LED used for disinfection purposes. They are said to be effective for any size of viruses and bacteria

    https://www.aquisense.com/technology

    Useful both for air and surfaces. also for other things like water,etc. They have no danger for skin when used in masks, because UVC wouldn't shine on skin for prolonged duration.

    I think development of active personal masks equipped with multiple hot electric fine wire-meshes and UVC LED could prevent widespread and reduce speed of spreading dramatically.

    I think many industries in China, Europe and developed countries could produce these masks quickly. Recently contacted a company in Iran that develops medical equipment to develop these active filters, but currently they are very engaged in producing ordinary masks. So I contacted European companies.

    A few people have reported that using a hair dryer below their nose at some distance away, has helped them improve against coronavirus disease. Report are not confirmed cases but those who have reported it have said they had similar symptoms of coughing.
    Obviously one can breathe hot air at 50 degrees C or higher and while atmospheric temp is cold this may have some incredible effect.
    Could hot air under special circumstances of body temp(environmental temp) have improving effect against coronavirus?

    It's okay to discuss current research efforts and encourage universal precautions such as handwashing but please, everyone stay well clear of recommending any specific treatments in your posts, conventional or otherwise.

    I felt it was important to do another emphasis: No.
    You can not change your core temperature any safe way. You can not freeze/cook microbes away without harming yourself.
    Please think rationally.

    Wait, wait, wait. You and A1call all of a sudden attack observations, very dangerous for a scientific forum to discuss about engineering developments that sometimes crop up from observations and repetition. No one is going to implement medical prescription for anyone.
    I have the latest news from most health organizations, and strictly advise you and a1call to take precautions when you are dealing with someone who knows that 45 medical specialists died and chief residents in hospitals who were infected and died say they know nothing what is actually happening and many people die without intense symptoms.

    Of course it is good to encourage people not to take unnecessary actions without advice. There are many who have claimed they have made medicine for treatment of coronavirus infection, and everyone should be aware that there is a long process to certify a medicine and should be aware of these things.
    Also some dealers all selling methanol instead of ethanol. They add some whitex to methanol and the color changes from yellow to clear color. The only way one could test it is to burn a little bit of it, if it burns blue then it is ethanol, but if it burns yellow then it is methanol.

    We should be aware of scientific discussions that pave the way to discoveries. There are many precautions not to use hair dryer also because the motion of the air spreads viruses and asbestos is used in it to hold hot element in place that are said to be dangerous for lungs if micro pieces of it enter breath.

    But in a science forum things are different, for example you know that UVC is very dangerous for skin, but UVC-LEDs are being implemented for disinfection of course after approval by health organizations. And there are precautions for their use.

    Yesterday I heard that a new vaccine was tested on humans. Previously I heard from Health minster in USA that a vaccine takes several months before being certified.

    There are people that voluntarily take medicines that are being developed. It means that medical equipment could also be tested by approved specialists on voluntary people.
    So results of the discussions in a forum if positive could be proposed to approved specialists to test them in laboratory and follow all scientific,medical and engineering rules to approve it and certify it.

    Now imagine specialists are dying without being able to do anything to save their lives. Also ordinary people. For the last minute of their life they are ready to take all sorts of medicine, as has been observed, and take any action to stay alive. A hair dryer you are using almost every other day and breath its outgoing air and has been approved safe for commercial use for everyone. This is quite different from non approved devices and medicine. You should be aware of what you are just saying " No" without any references and knowing that a hair dryer is quite safe and sound for all healthy people let alone for the one who is dying.

    Please give scientific answers to questions suitable for a science and technology forum, in a thread that discusses engineering developments.
    So apart from your thankful precautions, please answer my question. I don't accept religious answers on non religious topics. It is all scientific.

    That is a ludicrous statement. No one uses a hair dryer to breathe. The certification of being safe to use is only applicable to drying your hair. Petroleum is certified as safe to use too. In your car, not as a mouthwash.
    Please base your statements in reality.
