Fuel cell vehicle – Mode of action and possibilities

Fuel cell vehicle – Mode of action and possibilities of Hyundai Nexo. – So that the car can be fueled with the most ecological of fuels, hydrogen (from the exhaust pipe is extracted only steam). It must be provided with a compressed gas tank. For example, Hyundai Nexo, available on many European markets, has 156 liters of hydrogen. Which gives him a range of about 660 kilometers on one refueling.
The gas is supplied by cable to fuel cells . Where it is mixed with oxygen from the air. As a result of the reaction that followed. Electricity is produced and – as a by-product – steam. The resulting current drives the motor. Which in the case of the Nexo model generates up to 120 kW and allows a speed of 179 km / h.

Strongest acid – Fluoroantimonic acid

Strongest acid – Fluoroantimonic acid – Actually, it is a super acid that is a mixture of hydrofluoric acid (HF) and antimony pentafluoride (SbF5). It is a thousand trillion times stronger than concentrated sulfuric acid. Even short-term contact with the skin can result in serious injuries or death – just like inhaling its vapors. Fluoroantimonic acid is stored in special containers.

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.

Molecules from space – Primary gas after Big Bang

Molecules from space – Primary gas created shortly after Big Bang

Molecules from space – Primary gas created shortly after Big Bang – Has been confirmed the
hypothesis
about the origin of molecules from space. The researchers were able to discover
the so-called
. Primary gas, which was created shortly after the Big Bang, it consists of hydrogen
and
its heavier isotope deuterium. This finding confirms that in the Big Bang were created only the
lightest
chemical elements, hydrogen and helium. Heavier elements appeared only after 100 Mln years.

Chernobyl Disaster – Accident in nuclear power plant – In 26.04.1986 accident occurred
in the
nuclear power plant in Chernobyl, Ukraine. The cause was an explosion of hydrogen
in a nuclear reactor
. Contaminated surface was 125-146 thousands km² of Ukraine, Belarus,
Russia,
and the radioactive cloud was moving over Europe. Because of contamination
were evacuated
and resettled more than 350 thousands people.

Watches radioactive material

Watches radioactive material – Until the 60s of the twentieth century, commonly used in watches radioactive material – radium 226, so that their shields and guidance glowed in the dark. Today fluorescent paint which is coated dials comprises tritium. It is a radioactive isotope of hydrogen, but its small amounts are considered harmless to humans.

Martian methane – Detected in meteorites from Mars

Martian methane – Detected in meteorites from Mars

Martian methane – Detected in meteorites from Mars – Canadian researchers from the University of Brock, in six meteorites from Mars have detected the presence of methane. The researchers also found traces of carbon dioxide, hydrogen, nitrogen, oxygen and argon. Methane was formed in meteorites probably under the influence of chemical reactions, so it is not of biological origin as methane on Earth. Scientists believe that the volcanic rocks of Mars there are large quantities of methane, which could be a source of energy for underground microbes. This confirms the theory that the Earth there are microbes that live thanks to methane. They live on the bottoms of the oceans in layers of basalt and do not need oxygen. Signals the presence of methane in the Martian atmosphere appeared more than 10 years ago, but so far have failed to unequivocally confirm.
