It's settled.
This thing is the ultimate solution to the energy problem.
When it's actually applied, the energy crystal prototype that is manufactured is just an empty metal framework. Placed on an energy compressor, the compressor connects to a power source, and immediately the energy starts getting drastically compressed and fills into this metal framework, forming a beautiful blue crystalline body.
This thing is the Compressed Energy Crystal Block.
Essentially, this technology is not limited to any specific type of energy. Even if connected to a power station, it could also significantly compress electrical energy.
Of course, that's not usually done. The energy density of power stations, even nuclear power plants, is relatively too low. Generally, energy crystals are used to generate electricity, and one single energy crystal can last a long time.
