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.

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,
– 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.

Nyiragongo – Congo


  • Location: Congo
  • Peak: 3470 m a. s. l.

Nyiragongo volcano is located in the Virunga mountain chain and although its side craters are already extinct, the main one is one of the most active in the world. This stratovolcano is formed by a group of several volcanoes at Lake Kiwu. In the crater there is a huge lava lake, still active. The temperature of the lava located there varies between 800 and 950 ° C, has a thin consistency and flows very quickly. For this reason, the volcano is a constant threat to the surrounding cities.

The most horrible eruption took place in 1977, when lava flowing down the mountainside killed thousands of people. Magma got to the city of Goma, in which she destroyed 15% of the building and killed about 150 people. A stream of lava reached the shore of Lake Kiwu, forming a peninsula. Another volcanic eruption took place in 2002.

According to legends told by local citizens, Nyiragongo is a holy mountain. The natives believe that an enchanted spirit lives on it, which is trying hard to get out of its earthly dungeon. His angry scream explodes in the form of lava geysers and dense fogs.

Krakatau – Indonesia


  • Location: Indonesia
  • Peak: m a.s.l.

Krakatau lies between Java and Sumatra, and belongs to the most dangerous volcanoes in the world. We can also find out about it in the last days when the mountain awoke. Its largest explosion occurred in 1883. When the Perboewatan crater threw away a 6 km high cloud of ash, visible from a distance of 160 km. The next eruption occurred a few months later. This time, volcanic dust has risen to 27 km. In the final phase of the eruption caused the creation of four tsunamis high at 30 meters. The sounds of the crash were heard even several thousand kilometers away. More than 36,000 people have died as a result of the explosion and tsunami. These events affected the entire planet, as a result of the explosion the average annual temperature decreased by approx. 1.2 ° C. This year, the volcano has woken up again. After the explosion, a large part of it collapsed and caused a deadly wave of tides that killed over 400 people.

Algae Chlamydomonas – Different colors of snow

Algae Chlamydomonas – Freshly fallen snow seems pure white, although the snowflakes are transparent. This is because they reflect white sunlight evenly. We found 100 species of plants that live in the snow, coloring it in green, brown, purple and even blood-red. The last color is represented by monocellular algae from the Chlamydomonas species living in the colonies behind the Arctic Circle. Because they absorb more solar heat than the surroundings, so the snow around them melts, and the algae sink into the pits that cover the ice layer from above. In such micro – greenhouses a constant temperature of around 0 ° C prevails.

Aconitum napellus – One of the most poisonous plants

Aconitum napellus – One of the most poisonous plants.

  • Deadly dose: 3 – 5 mg
  • Death: in few hours
  • Poison: aconitine
  • Aftermath: heart and respiratory paralysis
  • Where it grows: in Western Europe and eastern North America
  • Occurrence in Poland: yes

All parts of this dark blue plant contain aconitine. The flower should not be touched (the poison is so strong that it can penetrate the body by applying a leaf to the skin). Poisoning does not occur often, mostly because the man has mistaken the root of the plant with horseradish or other root vegetables. Ingestion causes mouth burning, salivation, vomiting and fluctuations in blood pressure. In medicine, a tuber of aconite is used that reduces temperature in limited doses.

History of the plant:
In the Middle Ages it was used to poison swords and arrowheads. Teutons used venom during magical shamanic rituals, it was also a component of fairy ointments.

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.

KEPLER-442b – Stony exoplanet in superearth class

KEPLER-442b – Stony exoplanet in superearth class, which the parent star is the orange dwarf.

ESI: 0,84
Size: 1,3 Earth
Mass: 2,3 Earth
Equivalent temperature: -65°C

The planet KEPLER-442b, from which light has been running for 1115 years, belongs to the so-called Super-Earth. In this way, rocky exoplanets are determined whose mass does not exceed tenfolds Earth. The parent star of this planet is an orange dwarf. The star larger than a red dwarf, but smaller than a yellow dwarf, which is the Sun. This type of star has calmer youth, and therefore does not send its planetary children too much UV. In addition, the planet is in the ecosphere, so it can not be ruled out that the ocean is splashing on its rocky surface. If it has a more complex atmosphere, it does not have to be at the same time a kingdom of cold. According to some calculations, it is the smaller superearth that are most suitable for life, even more than our own planet.

Ross-128b – 11 light years away from Earth


Ross-128b – 11 light years away from Earth

Ross-128b – The planetary system around the red dwarf Ross 128 for about 70,000 years will become our closest star neighbor.

ESI: 0,86
Size: 1,2 Earth
Mass: 1,3 Earth
Equivalent temperature: 7°C

Even closer than the GJ 273b is the Ross-128b exoplanet. It is away from us, just like a star. Which is a very quiet red dwarf, less than 11 light-years away and gradually approaching us. Based on the obtained data, astronomers have discovered that planet Ross 128b circulates around its star twenty times closer than Earth circulates the Sun. Despite such a short distance, the planet gets only 1.38 times more energy than our planet. Thanks to the cool and stable star, whose surface temperature in comparison with the sun is halved, the equivalent temperature on its surface is estimated to be from -60°C to 20°C.

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.
