Energy logistics

Overview
Virtually all types of activities require reasonable logistics to minimize usage of time, efforts and resources and maximize efficiency of operations. Energy transfer isn’t an exception.

Continuous increase of energy sources' amount, provided mainly by stars, surrounded with stellar spheres, required more advanced and practical ways to transfer energy rather than using old and reliable methods Homelanders utilized for their first star.

Immense distances between stars was another, and the most important reason to create and introduce new methods of energy transfer.

Primary method
Firstand primary method which is, nonetheless, used much rarer than the secondary one, is opening an extremely small traversable wormhole. The smaller they are, the less exotic matter is needed to sustain them.

While not suitable for being used as a way to transport objects with mass, it is perfect for transferring energy from stars to the central energy core. It is preferable to use over intergalactic distances because energy requirements, albeit huge, do not increase with distance, which, eventually, makes this method preferable.

Another advantage of this method is immunity to cosmic inflation, because, unlike expansion-contraction, once opened and filled with exotic matter it is not affected by the distance.

Secondary method
Second and much more common method is expansion-contraction of space. While this method requires astonishing amount of constantly supplied energy, it’s still much lower than a traversable wormhole needs to operate, which makes this method preferable over the short and medium distances.

It is used mostly within galaxies to transfer energy from all its stars into a single point. From that point, energy either being transferred to the central energy core by the first or second method, depending on distance and direction of a galaxy’s movement.

Remote activities
Because of the nature of these methods, the Homelanders calculated that pure energy transfer is much more beneficial and requires less resources than using objects with noticeable mass, such as space vessels, instead.

It led to the most advanced and practical way to construct new stellar spheres and building logistics – transferring energy to a ‘construction site’ and use it to manipulate objects that are located in that area, such as asteroids.
