THE KARDASHEV SCALE
Kardashev Scale is a scale that defines technological development of civilizations. The method of this scale is doing that according to energy amount that can be used for communication. Scale has 3 categories those determined as a type 1, type 2 and type 3.
We will explain below those 3 categories;
Type 1 civilization: It named as a Planetary Civilization. This civilization can use and stock the energy that comes from near stars.
Type 2 civilization: This kind of civilizations can take and use all of energy of near stars. The most popular project of humanity to be type 2 civilization is Dyson Ball. To sum up, Dyson Ball Project aim to cover all around of Sun with Solar Collectors.
Type 3 civilization: These civilizations can use, collect and stock all energy of galaxy that they are living in it. This type of scale is totally hypothetical.
Why Kardashev Scale did named like this?
At first in 1964 Soviet Astronom Nikolay Kardaşev submitted this idea.
In 2012, the world energy consumption(tüketim) was 553 eczajoules (553×1018 J=153,611 TWh), which is equivalent to 17.54 TW of power usage, i.e. 0.724 on Sagan's scale.
