Abstract: We give general arguments that any interacting non-conformal {\it classical}field theory in de Sitter space leads to the possibility of constructing aperpetuum mobile. The arguments are based on the observation that massive freefalling particles can radiate other massive particles on the classical level asseen by the free falling observer. The intensity of the radiation process isnon-zero even for particles with any finite mass, i.e. with a wavelength whichis within the causal domain. Hence, we conclude that either de Sitter space cannot exist eternally or that one can build a perpetuum mobile.
