Thermonuclear energy – Obtained by fusion

Thermonuclear energy – Obtained by fusion – combining the nuclei of light elements. Under earthly conditions, it is possible to use isotopes, i.e. heavier forms of hydrogen: deuterium and tritium. The former has a proton and a neutron in its nucleus, and it is quite common in water. The second one, made of a proton and two neutrons, does not occur naturally. But it can be easily obtained from another light element – lithium.

JET (Joint European Torus)

Tritium is used in experiments at JET (Joint European Torus). Which is near Oxford, UK. It is a tokamak reactor – a bagel-shaped chamber in which the hot gas, i.e. plasma, will be trapped by the magnetic field. It must reach enormous temperatures, on the order of 100 million degrees Celsius, for the thermonuclear reactions to begin. – We have come to the point where we can try out in practice what we have been preparing for years. – explains Dr. Joelle Mailloux, co-leader of the JET science team.

This is the first major experiment with tritium since 1997. Because the use of this isotope as a fuel, along with deuterium, increases the level of radiation in the reactor. All the equipment had to be adapted to the new working conditions. It took two years. – Once the research begins, the inside of the reactor will be too dangerous for humans to enter. Everything must work or be repairable remotely, as on an unmanned spacecraft – says Prof. Ian Chapman, head of JET.

If successful in the UK trials, they will open the way to efficient and relatively clean energy production. One gram of hydrogen “burned” in a fusion reactor can yield as much as 8 tons of crude oil or 11 tons of coal. A few hundred kilograms of deuterium and tritium per year would be enough to meet the energy needs of the whole world. Relatively little radioactive waste is also expected to be generated in fusion reactors.

ITER (International Thermonuclear Experimental Reactor)

The results of the JET experiments will be used in the development of ITER (International Thermonuclear Experimental Reactor). This is a huge reactor under construction in Cadarache, France. Funded by the European Union, China, India, Japan, South Korea, Russia and the USA at a cost of $ 22 billion. The first launch of ITER is scheduled for 2025, 10 years later the reactor is to run on a mixture of deuterium and tritium. If all goes to plan, it will be the first plant to get more energy from fusion than was needed to initiate it.

TOI 700 d – Exoplanet from constellation Dorado

TOI 700 d – In early 2020, astronomers managed to discover a planet about the size of the Earth. They discovered it thanks to the Transiting Exoplanet Survey Satellit (TESS) – NASA’s space telescope. Designed to search for extrasolar planets by transit. The planet TOI 700 d, located relatively close to our solar system, orbits its own star. It is located approximately 100 light-years from Earth.


 
An Earth-sized planet lies within the habitable zone of its parent star. That is, circulating at such a distance from it that there are suitable conditions for maintaining the presence of liquid water on the surface. This, in turn, gives rise to presumptions about the existence of life there. TOI700 is a small, cool M dwarf with a mass of 30% of the mass of the Sun. Three planets orbit a star within the constellation Dorado.

Several similar planets were found in the TRAPPIST-1 system, named after the TRAPPIST telescope in Chile. Another was discovered thanks to the Spitzer Space Telescope.

TOI-700 is approximately 20% larger than Earth. The year on it lasts 37 earthly days. It receives 86% of the energy supplied by the Sun to Earth from the star. The exact conditions on it are unknown. But with the information gathered, the scientists prepared 20 models of potential environments. Able to reign on TOI-700. Some of these models suggest that the planet may be livable and colonized in the future.

Evergreen plants secrets – Retain metabolic activity

Evergreen plants secrets – Retain metabolic activity – Adapting it to winter conditions. They do it, among others preventing the formation of intracellular ice crystals. Their specific structure also helps them to survive the difficult conditions.
Conifer pins are narrow, which reduces the evaporation surface and prevents water loss. In this trees, the pins covers with a thick layer of wax skin, and the buds covers with thick shells. This makes the conifers able to survive even the most severe frosts.
Green in winter also remain, among others mosses, club moss, and some shrubs, such as rhododendrons. The leaves of the latter covers a special protective layer, and additionally, on frosty and sunny days, they curl or change from horizontal to vertical. This limits the amount of light reaching them. As a result, their evaporation surface is reduced and the plant protects itself against moisture loss.

Dead Sea salinity – Salt lake without outflow

Dead Sea salinity – 33.7%, which is 10 times higher than for normal water use. About 40 billion tons of salt are contained in the sea. By evaporating one liter of its water, you can get about 250 grams of this mineral. Due to the high salinity in the Dead Sea, which is actually a salt lake without outflow. There is no right life. For comparison, the salinity of the Baltic Sea is only about 7 ‰.

Dead Sea mud has antiseptic and bactericidal properties.

Rafflesia Arnoldii – Largest flower is parasite

Rafflesia Arnoldii – Rafflesia arnoldii, is the largest individual flower on Earth. It doesn’t have its own stems, leaves or roots. Parasites on vines of the Cissus genus, related to the vine. Deriving water and nutrients from the hosts. Rafflesia grows in a thicket of tropical jungles in Borneo and Sumatra.
It reaches a weight of 11 kg and a diameter of one meter. It consists of five fleshy, red, white speckled petals. Inside, it finds a few liters of nectar, and spike-like creations with an unknown function.
Rafflesia emit a specific, bad smell to rotten meat. In this way it attracts pollinating beetles and flies. That’s why the people of Indonesia call it a corpse flower. It blooms for 5-7 days, every few years. However, if pollinated, it produces round fruit. Containing thousands of tiny seeds.

Gary Gabelich – Exceeded by car 1000 km/h in 1970

Gary Gabelich – Exceeded with „Blue Flame” 1000 km/h in 23.10.1970. The average speed was 1001.011968 km / h. Mile, which is measured the speed of the vehicle must overcome two times: back and forth.
The big shiny „The Blue Flame” to save fuel even more. Was pushed by the service car at the start. It further helped him to accelerate to 60 km / h.
During the first run, Gabelich achieved a speed of 993.722 km / h as a result. He drove in the opposite direction, but a little faster – that’s why the speed was 1009.305 km / h.

Until then, records were set with jet engines.

„The Blue Flame” rocket engine was powered by a combination of hydrogen peroxide, and liquid natural gas. Chilled to a temperature of -161 degrees Celsius. As a result, achieved 58 000 HP.
In this way, the engine was running with maximum thrust for 20 seconds. „Blue Flame” was similar to a rocket, except with additional catches at the front and rear for attaching wheels.
Tires, specially designed by Goodyear, had a rather smooth surface to reduce heat.
The vehicle was 11.4 m long and 2.3 m wide. He weighed 1814 kg, with fuel – 2994 kg. One of the biggest troubles just before the start. There was burning through the engine, braking parachute ropes. If you had to stop the car with only disc brakes. You would probably need stretch, a 19 km length.

„The Blue Flame” designed and built by Reaction Dynamics.

With the help of the Illinois Institute of Technology lecturers and students. Dr. T. Paul Torda and Dr. Sarunas C. Uzgiris, professors at IIT, worked on the aerodynamics of the car. While other IIT students and lecturers, they mainly dealt with:
– construction,
– engine,
– steering system,
– brakes.

The speed record broken at Bonneville Salt Flats in Utah, USA.

This place is located 160 km west of Salt Lake City. Because 32 thousand years ago there was a huge lake 305 m deep. After it disappeared and the salt substrate hardened. It was created one of the most noteworthy places on Earth, to develop enormous speeds.

Gary Gabelich (29.08.1940 – 26.01.1984)

– During 43 years of life, this Croatian by origin. First of all, he won races, and set speed records on:
– asphalt,
Earth,
– water (motorboats),
– salt tracks.

He died on a motorcycle on the streets of Long Beach in January 1984. While working on the design and construction of a vehicle capable of reaching supersonic speed (1225 km / h). Prototype named „American Way”, but because of Gabelich death. Work on it canceled.

Chaitén – Chile

 

  • Location: Chile
  • Peak: 1122 m a.s.l.

 
Chaitén volcano for a long time was considered as expired. Over the last millenniums, no activity has been noticed. Caldera with a diameter of 3 km located in the southern part of Chile. It woke up suddenly in 2008, exactly after 9400 years. When the day before the explosion there was a series of smaller earthquakes. The cloud of ash and volcanic ash was 18 km high. After the outbreak, nearly all its inhabitants left the city. The soil was covered with a 15-cm layer of ash, which contaminated even water, which was a threat not only for people, but also for about 25,000 cattle.

Plants posing stones – Lithops of the succulents type

Plants posing stones – In the deserts of Namibia and Republic of South Africa grow Lithops, plants of the type of succulents, called living stones. It have to face not only high temperature, lack of water and nutrients, but also with animals, for which it is a tasty morsel. This plants use special camouflage. It thick, bulging and fused leaves resemble stones. Lithops reveal identity for a short time during flowering. In order not to lose water, many succulents do not develop stems and leaves. Thanks to this, it have a smaller evaporation surface.

ESI: 0,91
Size: 0,8 Earth
Mass: 0,3 Earth
Equivalent temperature: 15°C

The relatively small weight of this planet indicates that its surface can be flooded by a deep ocean.
According to some speculations, here is 250 times more water than in the Earth’s oceans.
The first measurements showed that the planet is moving outside of the living zone, but now it seems that it will enter it safely. Exoplanet can boast a dense atmosphere and is so close to its star that it circulates in four days. It only drops by 4.3% more light than on Earth. Although TRAPPIST-1d circulates its star in synchronous rotation, a dense atmosphere in which there should be a lot of water vapor helps in thermal exchange. The difference between the illuminated and the dark hemisphere is not like that of other celestial bodies.

TRAPPIST-1e – Exoplanet from system TRAPPIST-1

TRAPPIST-1e – The stony exoplanet of the TRAPPIST-1 system, according to physical properties, is the “e” from the planetary system TRAPPIST is the most similar to Earth.

ESI: 0,85
Size: 0,9 Earth
Mass: 0,8 Earth
Equivalent temperature: -22°C

It moves in the middle of the ecosystem of the entire collection, but there is the least water here. TRAPPIST-1e has a smaller size than Earth, but it has a larger mass. Possible inhabitants would have to be smaller in height and more important to cope with the pressure of local gravity. Red dwarfs, to which the TRAPPIST-1 star belongs, do not emit as much light and heat as the Sun. This means that the ecosphere, in which liquid water can sustain in proper conditions, is located in much closer orbits than in our solar system. A year on the planet TRAPPIST-1e lasts six ordinary earth days.
The planet probably also has a compact atmosphere where hydrogen is lacking. This type of atmosphere can also be found on the rocky planets of our solar system. Hydrogen is also a greenhouse gas, if it was a large amount in the local atmosphere, the surface of the planet would be uninhabitable.
