The impact of the new solar economy on communication networks and technologies, including the search for (and possibly communication with) extraterrestrial intelligence. The second chapter analyzes the impact of the new energy system on television, radio and mobile networks and on the Internet. This means that some of the new solar plants can also become important tools for radio astronomers.
The impact of the new solar economy on communications networks and technologies, including the search for (and possibly communication with) extraterrestrial intelligence. In communication networks based on radio waves, structures that focus radio waves, typically parabolic antennas, are one of the key elements.
The Emerging Modern Solar Economy
So it will not be possible to prevent the adoption of the new solar energy technologies. In the following pages I will first describe some of the most promising new solar electricity technologies and their potential. The spread of the technology has been slowed by the high price of effective semiconductor materials.
Because the transfer price of electricity is about half of the current price of power, grid power will not be significantly cheaper in the future. In the tropics it might be a good idea to install at least some of the plants on agricultural areas.
The New Radio Economy and the New Solar Economy
In the center of the glass roof is a large vertical chimney with large air intakes at the bottom. If large enough vertical axis wind turbines become available, the effect of the solar chimneys can be further increased. The roof of the greenhouse could also be used for rainwater collection with marginal additional costs.
At least 90 percent of the 250 existing satellites in low Earth orbit are not so shielded (DUPONT, 2004). However, the amount of energy collected is still directly comparable to the combined area of the radio telescopes linked together. In South Asian culture, such a notion has always been an integral part of religious and philosophical belief systems (TERESI, 2003).
We have a pretty good idea of the rate of star formation in our own galaxy: there are 10 or 20 new stars born in the Milky Way annually (McCONNELL, 2001). Oliver named the project Cyclops after the mythical Greek giant with only one eye in the middle of his forehead. But the cost of the project was deemed so high that the array was never built.
Therefore, it may be a good idea to place at least some of the solar dish arrays on cultivated fields in the tropics. When the sun sets in the westernmost parts of the giant continent, it is already rising in Eastern Eurasia. We know that most of the dark matter in our galaxy resides in the corona, the large invisible sphere that surrounds the galactic disk.

Solar Chimneys as Communication Towers
A Brief History of Radioastronomy and SETI
During the 1940s, several universities began constructing parabolic radio telescopes, and within a few decades radio astronomy became one of the most important fields in astronomy. Since 1960, the search for possibly existing extraterrestrial civilizations – other technological civilizations that use radio waves in their communication but live on the planets of other solar systems – has become one of the best-known sectors of radio astronomy. Fp means the fraction of the suitable stars that are actually surrounded by planetary systems.
Even these observations already proved that planetary systems are not rare, but it is likely that astronomers had seen only a small percentage of planets orbiting the observed stars. Such planets would be tidally locked, the same side of the planet always facing the star. On the other side of the planet temperatures would be permanently below freezing, and on the other side permanently above the boiling point of water.
But because no traces of alien civilizations were found, and because all efforts were focused on the search for alien civilizations - and not on conveying our greetings or messages to them - the first letter of the acronym was quickly changed. There is very little microwave radiation in most parts of the sky, and most stars do not produce much of it. When Arecibo transmits such a beam focused on its standard radar frequency, its apparent brightness in the region towards which the beam is directed is twenty million times that of the Sun, but only in a very narrow band of frequencies (Drake and Sobel, 1993).
In other words, with SETI@home the power of the search has increased roughly a hundred million million times since 1960. It will map the neutral hydrogen content of the galaxy for three-quarters of the sky. Fortunately, the situation may change, in a more profound way, with the advent of the modern solar economy.
The Modern Solar Economy, Radioastronomy and SETI
Such a program would completely eclipse all previous visions and dreams of SETI activists and researchers. If you increase the power of the transmitter, the reception range of the signal will increase in proportion to the square root of the increase in power. But there is also a narrow region where the focal length of the gravitational lens is infinitely long.
Due to the phenomenon of gravitational lensing, astronomers have been able to observe exoplanets orbiting stars tens of thousands of light years from Earth. Currently, there is near consensus that most of the missing mass in the universe consists of "dark energy" and exotic dark matter, and only a minor fraction is made of ordinary, baryonic dark matter (mostly hydrogen atoms). Only a very small part of the mass of Jupiter and Saturn, for example, consists of the heavier elements, including the radioactive substances.
What if the kind of stars and planets we know exist mainly in the densely populated parts of the galaxies, with large amounts of radiation and heat. That would give us serious reason to reconsider the validity of the dark energy hypothesis. The figure was absurdly low because only the impact of the nuclear explosions was taken into account.
This has brought the chemocline close to the surface and the hydrogen sulfide bacteria have captured most of the ocean water. For example, the great Permian mass extinction event occurred when the carbon dioxide content of the atmosphere exceeded 3,000 ppm. So, based on the existing evidence, it is reasonable to assume that the more advanced civilizations, the cosmic sages, largely use solar energy.
Hollywood movies like Independence Day and the War of the Worlds have conditioned us to fear alien civilizations. In 1976, the British Interplanetary Society developed a slightly different version of the same idea, called Daedalus.
Could we Send Messages to the Stars: From SETI to CETI
Choosing the Content: What Should We Broadcast?
Of course, it's very difficult to say whether an alien civilization would actually be able to correctly interpret any part of the message, even if someone intercepted it. However, American military scientists judged the fire damage to be so unpredictable that for fifty years they focused only on analyzing the impact of the explosion. If the share of nuclear energy in the global energy budget were increased to 50 percent, and total energy consumption were tripled, we would have 60 to 70 times more nuclear energy than we have now.
If a 10-meter tsunami - to say nothing of a 100-meter supergiant - hits a nuclear power plant, it will destroy its cooling pipes and the power sources of the cooling systems. If nuclear power production is to multiply, most new reactors must be fast-breeding reactors, nuclear power plants that can produce more nuclear fuel than they consume. Such bombs would be only slightly larger than bombs made from so-called weapons-grade uranium, which contains 93 percent uranium 235.
Most of the extra cancer deaths caused by tritium releases must actually occur much further than five kilometers from nuclear power plants, even though the effect can no longer be discerned from the background noise. The cumulative decrease in oxygen content in the ocean destabilized the so-called chemocline, the area where oxygenated water met deep water containing large amounts of hydrogen sulfide produced by anaerobic bacteria living on the seafloor. In fact, the cheapest way to influence the fate of other young technocultures might be to send an 18-bit signal consisting of the first five primes and a 7 into space.

However, the interstellar SuperOrion would have required 25 million megaton-class nuclear bombs to reach Alpha Centauri in 150 years, thousands of times more than humanity's combined nuclear arsenal at the height of the Cold War. A spaceship traveling at the speed of a million kilometers per hour, about one thousandth of the speed of light, would reach Proxima Centauri in 4,000 years.
