Energy use, entropy and Extra-terrestrial Civilizations / Energiahasználat, entrópia és földönkívüliek
Abstract. The possible number of extra-terrestrial civilizations is estimated by the Drake-equation. Many articles pointed out that there are missing factors and over-estimations in the original equation. In this article we will point out that assuming some axioms there might be several limits for a technical civilization. The key role of the energy use and the problem of the centres and periphery strongly influence the value of the L lifetime of a civilization. Our development have several edifications on the investigations of growth of an alien civilization.
