ARM Backup/Surge Concerto/Genomirai Wiki/Tz-Waves

Translation of this article.
Whenever the planet reaches one of its semestral points of contact with the Sun's orbit through the galaxy, the Tz-Waves reach their max and minimum levels, while in the meantime they are constantly increasing or decreasing.
The change in the Tz-Waves' density one second before and one second after said events ends up transforming into energy.
Naturally, the difference levels are extremely low during spring and autumn, as well as during the days prior to the summer solstice and the winter solstice, which means the amount of energy they produce is quite low.
This is why these energies are stored in wave batteries.
Therefore, we could simply describe them as [space tidal power generation].
