１平方メートルの太陽光発電パネルの出力は約１ワットであり、今のところ大規模に太陽電力を利用するのは困難である。の英語

The output power of a one square meter solar panel is about one watt, so it is difficult to use solar power on a large scale at present.

For the new solar battery, titanium is dyed one of the various colors and then combined with thick fluids that don't vaporize at room temperature.

a method of electric power distribution called conduit-type power distribution

It is said that one gram of fuel composed of deuterium and tritium can produce as much energy as eight tons of petroleum.

of or relating to elementary particles having energies of hundreds of thousands of electron volts

either of two fine mutually perpendicular lines that cross in the focus plane of an optical instrument and are use for sighting or calibration

a cgs unit of illumination equal to the brightness of a perfectly diffusing surface that emits or reflects one lumen per square centimeter

suppress (sparking) when the current is cut off in an inductive circuit, or suppress (an oscillation or discharge) in a component or device

used of a compound (especially of carbon) containing atoms sharing more than one valence bond

It was announced that there is a high possibility of the fuel within the nuclear reactor of Nuclear Plant 1 melting.

a unit of electrical resistance equal to the resistance between two points on a conductor when a potential difference of one volt between them produces a current of one ampere

an electrically charged particle built up from polymeric molecules or ions and occurring in certain colloidal electrolytic solutions like soaps and detergents

As for the air, there is always some moisture in the atmosphere, but when the amount increases a great deal, it affects the light waves.

a nuclear weapon in which enormous energy is released by nuclear fission (splitting the nuclei of a heavy element like uranium 235 or plutonium 239)

the ratio of the electromotive force produced in a circuit by self-induction to the rate of change of current producing it, expressed in henries

a luminance unit equal to 1 candle per square meter measured perpendicular to the rays from the source

a self-luminous diode (it glows when an electrical field is applied to the electrodes) that does not require backlighting or diffusers

the highest region of the ionosphere (from 90 to 600 miles up) which contains the highest concentration of free electrons and is most useful for long-range radio transmission

a photographic image produced on a radiosensitive surface by radiation other than visible light (especially by X-rays or gamma rays)

a coil of low resistance and high inductance used in electrical circuits to pass direct current and attenuate alternating current

electric lamp consisting of a transparent or translucent glass housing containing a wire filament (usually tungsten) that emits light when heated by electricity

When an object moves away from Earth, the light that it is giving off is seen in longer wavelengths. When an object moves toward Earth, the light that it is giving off is seen in shorter wavelengths.

a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion

of or relating to or containing cerium especially with valence 4

a microscope that is similar in purpose to a light microscope but achieves much greater resolving power by using a parallel beam of electrons to illuminate the object instead of a beam of light
