Hydrogen vehicle

A hydrogen vehicle is a vehicle that uses hydrogen as its onboard fuel for motive power. Hydrogen vehicles include hydrogen fueled space rockets, as well as automobiles and other transportation vehicles. The power plants of such vehicles convert the chemical energy of hydrogen to mechanical energy either by burning hydrogen in an internal combustion engine, or by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling transportation is a key element of a proposed hydrogen economy.

Hydrogen fuel does not occur naturally on Earth and thus is not an energy source; rather it is an energy carrier. As of 2014, 95% of hydrogen is made from methane. It can be produced using renewable sources, but that is an expensive process. Integrated wind-to-hydrogen (power to gas) plants, using electrolysis of water, are exploring technologies to deliver costs low enough, and quantities great enough, to compete with traditional energy sources.

Isotopes of hydrogen

Hydrogen (H) (relative atomic mass: 1.00794) has three naturally occurring isotopes, sometimes denoted ¹H, ²H, and ³H. The first two of these are stable while ³H has a half-life of 12.32 years. All heavier isotopes are synthetic and have a half-life less than one zeptosecond (10⁻²¹ second). Of these, ⁵H is the most stable, and ⁷H is the least.

Hydrogen is the only element whose isotopes have different names that are in common use today. The ²H (or hydrogen-2) isotope is usually called deuterium, while the ³H (or hydrogen-3) isotope is usually called tritium. The symbols D and T (instead of ²H and ³H) are sometimes used for deuterium and tritium. The IUPAC states in the 2005 Red Book that while the use of D and T is common, it is not preferred because it can cause problems in the alphabetic sorting of chemical formulae. The ordinary isotope of hydrogen, with no neutrons, is sometimes called "protium". (During the early study of radioactivity, some other heavy radioactive isotopes were given names, but such names are rarely used today.)

Easy!

Easy! (Italian: Scialla!) is a 2011 Italian comedy film directed by Francesco Bruni.

Cast

Plot

A retired teacher and novelist (Bruno), who survives by private tutoring, is currently writing the biography for former adult star (Tina). He then discovers that one of his students (Luca), a teenager who is on the brink of failure at school, is actually his son.

Music

The twelve tracks of the original soundtrack were produced by The Ceasars and sung by the Italian rapper Amir Issaa, then published by EMI Music Publishing Italy. The official videoclip of the film, directed by Gianluca Catania, won the 2012 Roma Videoclip Award. The Ceasars and Amir were nominated for the 2012 David di Donatello Award and Nastro d'Argento (silver ribbons) for the song “Scialla” and won the 2012 “Premio Cinema Giovane” for the best original soundtrack.
