You are right, asteroids with a predominantly metallic composition are dangerous; in the crossing of the atmosphere they lose little mass and therefore maintain a high energy value that in the impact becomes destruction. However, we must not underestimate the rocky ones, the larger ones, are equally dangerous because if they do not consume or shatter in the crossing of the atmosphere they have enough energy to create even devastating damage. An example of the power that gives off ferrous asteroids/ meteorites can be observed near Flagstaff: the meteor Crater produced by a meteorite of about 50 meters in diameter ( 1.2 kilometers of diameter and 170 meters in depth). Tomorrow, having developed an adequate technology, they can be a source of raw materials, but given the costs of exploitation, will they be Resources actually accessible to everyone?

I agree . Coronal mass emissions (solar plasma) are dangerous for our satellites ( telecommunications, observation both towards the Earth and towards the universe): in areas where the hole in the ozonosphere caused by the missions of human activities coincides with inhabited areas, losses of electronic equipment and heavy disturbances in telecommunications will be possible. What generates the aforementioned emissions is a mechanism of The Sun on which the appropriate studies are being carried out. As I said in another post, the rise in sea levels is due to the effects of greenhouse gases and the deposit of soot produced by the combustion of fossil energies that feed our society. Our planet has become a duller body and therefore absorbs greater amounts of heat. The expected sea level, once the Greenland and polar ice sheets melt will reach 6 meters above the current level. Imagine a storm with mare forza 7 (Big Sea) with waves between 6 and 9 meters high; this value should be added to the quiet sea level . We are talking about heights compared to today's that arrrivo at altitudes of 12/ 15 m . Imagine resorts like Florida, Seichelles Islands and all the atolls that make up the pressing multitude in the Pacific Ocean. Imagine the difficulties of navigation between the Mediterranean Sea and the Atlantic Ocean; currently the Mediterranean is at - 20 cm relative to the Atlantic Ocean. What would happen with a rise of 6 meters?. By 2100, scientists predicted the likely loss of 6,000 square kilometers of coastline in Italy alone. Finally, if a coronal mass emission starts, it travels at a speed that our spaceships look like turtles in comparison. We need to rebalance and improve the screens of our Spaceship Earth, we have no other choice for this century.

OHOU Dirk! Since Government has issued its Regulation No4, there is no need to have 100 local Residents to have someone filling the position of City Representative. One can become an 'Acting City Representative'! In that same Government Regulation, the number of 100 is actually reduced to 10 Residents. I hope that helps! https://asgardia.space/en/news/regulation-no4

What you say is not far from the truth; just think of the communicating vessels and tectonic movements that can cause patency between the reservoirs and the porosities of the subsoil that housed the oil fields. However, I do not believe that this can affect drought ; if anything, it affects the heat that accumulates in the atmosphere . It is the hot/cold mechanism that allows precipitation . If the temperatures increase, both the maximum and the minimum increase, raising the absolute energy values until the condensation limits that allow the rain to fall are exceeded. The great heat that we are experiencing in Europe, in recent months, has already caused damage to the environment and victims ( I am referring to the great avalanche that occurred in the Italian Alps) and I believe that we will live the next few years with progressive and increasingly intense heat waves. I would not worry about the lack of water ; if and when the Arctic and Antarctic ice sheets melt, sea levels will increase, in height of over 6 meters covering many enchanting Islands and beaches. Desaliners will become convenient, but the environment will go towards one . Beyond this damage, I learned that, for the third time since the beginning of the Millennium, our planet has increased its rotation speed by reducing the duration of the Earth's day by 1.59 milliseconds , it is only instrumental, but if we consider the masses of melting water are weights with many zeros behind the first digit. These, due to the rotation, are positioned on the equator increasing the flywheel effect and increasing the speed of rotation, thus decreasing the duration of the day. Now what happens to the fluid core of the planet that ensures the formation of van Halen fascias? For the moment the planet vibrates at a greater and increasing frequency than that identified at the time. So many things connected with each other. Have we been very good at compromising our planet?

Good intentions! In the history of this now overheated world many have spent to improve the living conditions of at least a part of humanity. Something good has been done, but the perception has been lacking that we live in a soap bubble ( so much is the delicacy of the Earth System), the space between men is reduced, non-renewable energy is consumed, one always wants something more and in the end one struggles to have it. There is a lack of balance in the Earth System. Think of Asgardia as a small (at the moment) new beginning avoiding those mistakes that have made the history of humanity. It is a blank canvas on which to write new and positive chapters of history . Dialogue and understanding are the first tools.

The closed system you describe is based on the exploitation of the ability of a black body to absorb the energy of the sun's rays by transferring it to ICE which turns into steam which in turn contains the energy to be transformed into propulsive thrust. It closely resembles the principle by which the Stirling engine works. Its characteristics (merits and defects) can be found on the internet. Let's meditate, there is good!
