aerators solar cars?

Bought all those fans who are exploited by the sun so that your car can be cool. These devices that go on your window pulls the heat out. Thank you!

I have not bought one yet, but I do 'll probably, if I can find a good price. They have been around for some years and the first I heard connected to the cigarette lighter. I think c'est une bonne idée pour un climat chaud, comme la Géorgie ou la Floride.

Solar Power Importance – How It Can Create A Prosperous Future

We are indeed fortunate to live in a world of modern technology which has provided us the convenience of electricity at the flip of the switch. Most of our modern gadgets run on electricity and sudden power outages frustrate us no end. We take all this for granted and therefore cannot imagine a world without electricity or fuel for our vehicles. Neither do we stop to think that conventional energy which is obtained from natural resources like fossil fuels will not last forever. In the present scenario of global warming and ozone layer depletion, the world needs to make a lifestyle change to protect the environment for the future generations. We have to seriously look towards alternative energy and alternative fuels to take care of our needs.

Nature has provided us with an unlimited source of energy in the form of solar power. This is a natural resource, freely available and will be replenished as long as the Sun shines. Solar power is the energy obtained from the heat and rays of the sun. Solar power has many uses. It can be used to generate electricity using photovoltaic solar cells and concentrated solar power. It can be used to heat buildings directly by passive solar building designs, or cooking and heating food with the help of solar ovens. Solar Chimneys can be used to heat and cool air.

Alternative energy is the future trend and most of the technologies pertaining to alternative energy depend directly or indirectly on the sun. Solar energy drives the atmosphere and virtually supports all life on Earth. Heat and light from the sun along with hydropower, geothermal power and wind energy account for most of the flow of renewable energy. Solar Power refers to the process of conversion of sunlight into electricity. The electricity can then be used to power up our homes, businesses and industries to continue the cycle of life.

Agriculture depends on solar energy. Plants use sunlight for photosynthesis and thus produce food. Heating, ventilation and air conditioning systems are closely related and use solar power as their source of energy. Solar water heaters were the earliest use of solar power and continue to be used even today. Solar cookers used for cooking and drying foodstuffs offset fuel costs, reduce demand for firewood and improve air quality due to reduction of smoke. Domestic use of solar power is the best way to conserve our natural resources.

There are many technologies which are being used to harness solar energy. Applications span through the residential, commercial, industrial, agricultural and transportation sectors. Solar energy can be used to produce food, heat, light and electricity. The flexibility of solar energy is manifest in a wide variety of technologies from cars and calculators to huge photovoltaic plants. Recent price hikes and erratic availability of conventional fuels are factors that are renewing interest in solar heating technologies. Thus solar power is important to the very existence of the world as a whole.

What are the concepts of a Dyson Tree and Astro-chicken from Freeman Dyson?

Dyson trees are hypothetical space-grown lifeforms that feed on comets and can serve as potential living space for humans.

Astrochicken is a hypothetical self-replicating bio-cybernetic space probe.

Both concepts are the creations of the mind of Freeman Dyson.

Astrochicken is the name given to a thought experiment expounded by theoretical physicist Freeman Dyson. In his book Disturbing the Universe (1979), Dyson contemplated how humanity could build a small, self-replicating automaton that could explore space more efficiently than a manned craft could. He attributed the general idea to John von Neumann, based on a lecture von Neumann gave in 1948 entitled The General and Logical Theory of Automata. Dyson expanded on von Neumann’s automata theories and added a biological component to them.

Astrochicken, Dyson explained, would be a one-kilogram spacecraft unlike any before it. It would be a creation of the intersection of biology, artificial intelligence and modern microelectronics—a blend of organic and electronic components. Astrochicken would be launched by a conventional spacecraft into space, like an egg being laid into space. Astrochicken would then hatch and start growing a solar energy collector. The solar collector would feed an ion drive engine that would power the craft. Once Astrochicken entered a planet’s vicinity, it would collect material from the moons and rings of the planet, taking in nutrients. It could land and take off using an auxiliary chemical rocket similar to that used by bombardier beetles. It would periodically transmit details of its journey when it could make radio contact with Earth.

The term “astrochicken” does not occur in Dyson’s earliest essays regarding von Neumann-inspired automata. When Dyson was giving a lecture in Adelaide, Australia on the subject of space exploration with biotechnology, an audience member called out “Oh, you mean this is an astro-chicken.” The whimsical name caught on, and Dyson began to use it himself in subsequent essays he wrote on his theoretical biotechnology spacecraft.

Today, Dyson’s Astrochicken resonates with several theories of how space exploration might proceed in the future. Computer scientist Rodney Brooks has proposed sending a multitude of cheap, bug-like robots to explore Mars instead of solitary, expensive rovers. Cheaper and smaller means of studying space have also been the primary design philosophy of NASA for many years, perhaps best exemplified by the Mars Pathfinder mission. Physicist and noted author Michio Kaku wrote in his work Hyperspace, “Small, lightweight, and intelligent, Astrochicken is a versatile space probe that has a clear advantage over the bulky, exorbitantly expensive space missions of the past, which have been a bottleneck to space exploration. … It will not need huge quantities of rocket fuel; it will be bred and programmed to ‘eat’ ice and hydrocarbons found in the rings surrounding the outer planets”.

In recent years, Dyson has referred to Astrochicken as a “joke”, though it is not quite certain what he means by this. He went on to say “I think it’s a sensible idea, but one shouldn’t take it literally. We don’t have the science yet; we don’t have the technology. It would be a disaster if NASA tried to do this in the bureaucratic NASA style.”

As a noted author of essays on the possibilities of science in the future, Dyson’s theories, such as the Dyson sphere and the Dyson tree, have become popular in the scientific and science fiction communities. The more whimsically named “Astrochicken” has not achieved this same level of fame.

A Dyson tree is a hypothetical genetically-engineered plant, (perhaps resembling a tree) capable of growing in a comet, suggested by the physicist Freeman Dyson. He suggested that such plants could produce a breathable atmosphere within hollow spaces in the comet (or even within the plants themselves) utilising solar energy and cometary materials, thus providing self-sustaining habitats for humanity in the outer solar system.

A Dyson tree might consist of a few main trunk structures growing out from a comet nucleus, flowering into branches and leaves that intertwine, forming a spherical structure possibly dozens of kilometers across.
