Can catastrophes be avoided?




These are solutions for several kinds of catastrophes. Most of them are classic ones. For sure some of them are bad ideas. But I don't know yet why and which ones so I mention them all. The idea of this text originated when talking with a friend about the fact solutions to major threats should be searched for.

Tornadoes and hurricanes

They are due to the fact the Sun heated the ground surface. So there is a layer of hot air just above the ground. That hot air "wants" to rise but it cannot. Once the hot air layer becomes too thick or if there is an external perturbation, a giant bell of hot air will form at one given point. Like in a lava lamp. That hot bell will rise in the air and form a way towards the sky. The surrounding hot air will flow towards the point were the hot air bell rises. That's the formation process of the tornado. The tornado column is that point where the hot air has a path to the sky. The fast rotation of the tornado is due to the rotation of the Earth. The air zones rotate slowly with the Earth but when they speed towards the point of the tornado basis the rotation accelerates drastically. (That's the reason why the water in your wash-hand basin rotates when leaving through the hole. It's a mini-tornado directed towards the ground.) After a short time the tornado would have sucked up all the surrounding hot air and die away. But often it will move towards another zone where hot air is trapped near the ground. So it keeps active and sweeps over a distance: hundreds of meters or thousands of kilometers. The surface it sweeps over will be emptied of its hot air. The tornado sort of eats the hot air away. It's her fuel. Till there is no more hot air to suck/allow to rise. Then the tornado will die, going out of energy. Its rotation will decrease and stop. What can be done to avoid the formation of a tornado and its destructive journey? Maybe in the future man will be capable to avoid the formation of the hot air layer by influencing the Earth meteorology. But at today standards the solution seems to be a backfire. Weak tornadoes should be triggered all over the country once the hot air layer is forming. So the hot air won't accumulate and no strong tornado will form. Besides if the tornadoes are triggered on purpose people can protect themselves. To start a tornado there seems only one way to me: create a bell of hot air. To warm the air many ways exist. One is to make a ground array be dark colored. So that array will be warmed up by the Sun and will become the start point of tornadoes. The tornado may even not leave the zone and simply suck away the surrounding hot air constantly. (This could be a bargain for air sports.) A complementary way round is to draw giant paths of dark spots on the country. That way the tornadoes will tend to follow the same path every time and can be made to avoid some places. Another way is to vaporize a huge quantity of combustible gas in the air and light it. The hot air will rise and start the hot air column. Now about hurricanes. Why is a hurricane so much powerful than a tornado? Main reason, I believe, is the hot air above the Ocean is filled with water vapor. By condensing while the hot air rises the water vapor keeps the air hot. So it can get to much higher altitudes and contains intrinsically more energy. Hurricanes die when they arrive over land. But they are so huge and contain so much wind speed and rotation energy that they will spend a long time over the land, destroying everything around. The solution would be to start mini-hurricanes ways offshore, a few hours or days before the real hurricane comes by. That way it would find no more hot air to feed from and it would die away before reaching land or will follow another path. Can the Ocean surface be made black? Maybe with carbon powder. Maybe the carbon can stay in the air for a while as a dust cloud.

An example of the fact the suggestions above may be dangerous: in some cases tornados are powered by the Jet Stream. That is a fast and narrow beam of wind that speeds at high altitude. Once a natural chimney of hot air has opened a path towards the Jet Stream passing above a territory, the Jet Stream will literally suck away the air through that path. So opening that path using the techniques mentioned above could cause the problem instead of avoiding it. That's the sort of things that has to be tried out and computed carefully.

Water floods

Water floods are common around modern inhabited zones ones it rains too much. That's because the former river array has been restricted. Many things are done to avoid or decrease the water floods: buffer basins are created, weather forecast allows to decrease the river levels and empty the basins before the rain starts, ground arrays are managed so the water can soak inside the ground... There is one thing I didn't hear about yet: set a construction rule telling everything around a river should be placed a way to allow the water to flow in the river's normal flow direction. Indeed the problem when flood water enters a for example a city is the water inside the city streets won't flow. Only the water above the river will continue to flow. The water in the city streets will only flow back towards the river once the river level decreases. But should the city streets and buildings be arranged so the water can flow through the city too, and so all along the river, the flood will rise less high and spend less time. One drawback is the city streets will become dangerous during the flood. Because of the strong water flow. But this can be coped with provided the inhabitants are trained. Light bridges can be installed between the roofs, for example.

Forest fires

Firemen have many techniques to battle forest fires. One radical approach would be to build and buy many more water dropping airplanes. But a more subtle approach would be to rely on early alert. Once there is a risk for fire, little airplanes should hang in the air above forest zones, with high resolution infrared cameras. Water dropping planes should be in permanent alert. Once there is a fire start, when it's no more than a few trees burning, a massive concentration of water can be dropped on it. Early alert is a key to effective fire operation. But this seems to lack currently.

Global Warming

I'm not sure Global Warming is a bad thing. Many icecold countries will get a warmer weather and many tropical hells will get a colder weather. Better agricultural yields are awaited too. Maybe best would be the countries that suffer from the Global Warming get compensations. Local problems like desertification can be coped with by using adapted agricultural techniques to create forests. This all has to be debated at the United Nations and the choices belong to mankind as a whole. Reasons to stop the warming exist. The coral reefs are dying and there is a menace the warming can diverge and become a threat to mankind. But I don't understand why Global Warming is seen as a fatality neither why such extreme things have to done like drastically breaking down the energy consumptions of countries. Each time a volcano bursts open the Earth temperature decreases a little. That's because the dust particles send high in the air by the volcano will hang there for a while and will reflect a little part of the sunlight back to Space. The heath radiation coming from the ground on the contrary are not send back to the ground. They pass through the dust. So there is no greenhouse effect and the global Earth temperature decreases. Why does no nation plan to send airplanes in the air with tons of fine white dust? The time the dust hangs in the air can be tuned by choosing the dust particles size. So a first trial would not thy down mankind for a long term. Other ways to send fine dust particles high in the atmosphere exist. Like blowing giant cloud of a mixture of hot air, dust and a little water vapor, through a big blowpipe chimney. Or blowing a mixture of air and a black dust that whitens after a while. The bell of black dust will be heated by the Sun and rise in the air. Air humidity is one of the keys of Global Warming. Dust particles can act on that parameters several ways. For example they can increase the condensation inside clouds hence force them to rain. Maybe the weather can be influenced to some extend by building dust blowpipes all over the World. The kind of dust would be chosen for each blow session according to the short-term effect intended on the local weather but bearing in mind its long-term effect on the global weather. Apart from its optical and pshysical behavior, a dust can also be chosen according to its chemical properties. For example it can have an action on some of the greenhouse effect gases. Changes into the habits of humans can change things drastically. TV adverts propose to put one more cloth on in winter time and to diminish the house heating just a few degrees. A proposal I can make is to eat less starch and more fat. And less industrial products and more organic products. When I do so in wintertime I literally become a human heater. I have to put the house heating to a minimum or even switch it off.

It seems the water vapor produced by airplanes contributes a lot to the global warming. I suppose trains and ships will regain interest. Also maybe airplanes flying at low altitude and lower speeds, like in the thirties.

Local warming

Very hot weather is the meteorological phenomenon that causes the most casualties. I heard on TV thousands of people died in France because of the high temperature of recent days. I could see a few picture of rooms were old people live and suffer from the temperature. The room windows are open, closed or have curtains closed. Should I do this with my own windows when there is a lot of Sun, at the end of the day the temperature would rise so high in my room I wouldn't be able to stay. Even naked and with a ventilator I'm dripping in sweat and I feel bad. But I spend each afternoon at home and feel very comfortable. Maybe I just remove my T-shirt or take a shower. What's the trick? I simply covered the outside of my windows with aluminum foil, glued down with tape. That costs a few € and took me an hour work. (Worst difficulty is to stretch the foils or put them straight against the window glass, to avoid they flap with the wind and make noise.) I also keep the windows tightly closed once the Sun begins to hammer on them. I open them once the Sun is gone. I keep them all night long open to allow the inside room walls to cool down. The aluminum foil in front of the windows sends away all the sunlight. When the sun is allowed to enter, the heat it creates inside is tremendous. The energy amount is comparable to that of an electric heater. Putting a curtain behind the window, even a white one, does help but not a lot. Ones the light entered, a fair amount of it will be turned into heat. If you really cannot cover the outside of the windows with aluminum best is to use it inside anyway, but really tight close to the window and surrounded by tape so air cannot flow between the aluminum and the window. (Bear in mind aluminum foil has one side more reflective than the other.) The reason why the windows must be shut once the Sun shines is the air on the outside walls can be very hot. Opening a window means that hot air will enter (except when there is a lot of wind). A window can only be opened once the air on the wall cooled down. So I live in a protective closed shell while the Sun is shining. (Windows the Sun is not shining on and that are not surrounded by hot air can be opened, of course). Other points worth talking about is what happens inside the room when it is closed up. Electric devices like TV, refrigerators, lamps or modern computer can consume a lot of energy hence participate to warm up the room. This shouldn't be taken up too seriously. One or two 100 Watt devices won't make the room temperature rise a lot. But best use neon lamps and portable computers. Refrigerators are vicious: the higher the temperature, the more energy they will consume so the more they will add to the room temperature. Best place them in an uninhabited and ventilated room (air circulation inside the room is precious for refrigerators and energy-saving). A key problem inside a closed room is humidity. The more of it, the more the air temperature will be painful. A friend pointed out the air conditioning in modern buildings tunes the temperature but also the humidity level. Indeed humid air at 100% concentration can kill at 40 °C while dry air can be livable at 100 °C. Another friend who lived in Africa told me at the same temperature of 45 °C, one African country was a hell while the other was a paradise. Because the first one was very humid and the second one had only 20% humidity in the air. It is better to decrease the humidity than the temperature. So be cautious with humidity coming from bathrooms or kitchen. Close the doors and open some window. My friend also pointed out during warm days our ancestors washed themselves up and cooked their meals outside their houses. Other ways round than aluminum foil exist to cope with the sunlight. Specialized enterprises propose high technology plastic films that can be placed very aesthetically on the window's outside. You even can see through. Curtains can be hung outside the windows. Shutters can be installed. The walls can be painted white or be insulated. Trees can be planted in front of the Sun... Once the Sun fades away and you open the windows, you can use a ventilator to speed up the arrival of cool air inside the house. Place the ventilator as for away you can from the open window but with its air stream directed towards the window. That way the hot air is forced out of the room. This needs to go on for a few hours, till the inside walls and ceilings cooled down. (One can think out of this that best is to have little windows. But you must also plan a house for winter time. Then it's best to have huge windows facing the Sun. Best compromise is perhaps to have huge isolated windows facing the Sun, with a tunable system on the outside to reject the sunlight in summertime...) Many systems exist to enhance the conception of a house and make it suitable for both wintertime and summertime : turning houses, special paints that take up the heat, electronic windows...

Personal warming

The Sun is a nuclear furnace. It's radiations are dangerous, even if the most dangerous of them are filtered away by the atmosphere. Worst that can happen to your body is to be altogether irradiated by direct sunlight for hours, be in warm weather and loose body water. This will destroy a tremendous amount of body cells. At the end of the day at best you will be weak, most probably you will be sick and vomit. This can even kill. If you are badly hit, put the harmed body parts under a cool water stream (like for fire wounds) and go to the physician. You have to protect yourself. Cover your skin with trousers and a hat. (The level of protection you need depends on you particular nature.) Use clothes made of vegetable fibers since synthetic fibers won't protect you. Possibly wear eye protections like quality sunglasses or add-ons (low quality eye protection can be worse than no protection). Eat only carbohydrates at midday. Drink water constantly. Try to stay in the shadow. Wearing trousers and a hat when the weather is hot may seem nonsense. But provided you're moving this is more comfortable than wearing a short and no hat. Once you get home, remove the trousers and the hat. It's like wearing a scarf and a coat in wintertime: you have to remove them when you enter a house and put them back on when you go out. I you can afford, quality clothes exist that are really cool in summertime and warm in wintertime. Even when the temperature is acceptable it may be better to wear a hat and eye protection. This is especially true when there is a continuous thin layer of clouds. Because they let the Sun ultra-violet radiations through. A friend had severe problems of headache and pain in the eyes when she went out of her house. Now she's wearing a hat and eye protections and she has no more problems. Even if you feel you get no problem with sunlight, try wearing a hat for a few days. You may realize you are in a better shape the evening. During hot summertime people with a lot of body hair can suffer more than the others. A simple solution is to shave everything away. That makes hot weather a lot more livable. It's cheap, easy, and a lot less polluting than air conditioning.

Epidemies

Antibiotics and antiviral drugs are just wonderful. But the key to avoid sicknesses spreading is hygiene. Most endemic sicknesses in Europe were tamed by hygiene, long before drugs were invented. Hygiene is a technology as a whole. It means using disinfectants, washing up things and yourself, removing the garbage at due time, change social habits, changing clothes often... The most difficult epidemic to fight are those of sexually transmissible sicknesses. Thats a matter of spiritual level. You only can better that point by making people more aware of what they are. But hygiene has to be well understood. The purpose is not to avoid every germ. People doing so get severe sicknesses like allergy and asthma. They become more vulnerable to dangerous sicknesses too. We need all kinds of sicknesses to keep our immunity system fit and healthy. The challenge is to avoid dangerous or mutilating sicknesses and collect the other kinds. I expect in the future people will to their shopping at the local pharmacy to choose sicknesses for themselves and for their kids.

Civil War

There can be many reasons to a civil war in a country, like a mafia activity or foreign countries influence. In such cases the remedy is to attack the source of the problem. Often the reason why such people or foreign country destroy the country by civil war is to get hold of local resources. So an international regulation of that resource may the solution. When the civil war is due to fights amongst politicians of the country, the aid of international negotiators often can calm things down. But I'd say the canonical civil war cannot be solved by any of these means. A real civil war is when huge different parts of the population go mad against each other. This can be triggered or enhanced by propaganda or the like. But the key problem is that opposition deep inside the population. One reason of the Rwanda Genocide is the European negotiators thought they could solve the problem by forcing the political leaders to negotiate and settle agreements. So they did. But the tensions inside the population were too strong and burst open to the genocide. In such cases neither humanist propaganda nor UN troops will solve the problem. To me the country as a whole should be treated like if it was a person with mental problems. Radio devices should be given to each family. Day after day, the opinions and values of each camp should be exposed, explained, praised and criticized. That will make the people's minds evolve and weaken the tensions. Solutions and new opinions will be proposed and a common base will arise. The role of the politics will be to reflect that evolution of the population. So democracy is a key part of the process, with a democratic countries' survey.
