  A new approach to extraction of quantum vacuum energy, in the context of the
accelerated expansion, is proposed, and it is shown that experimentally
realistic orders of values can be derived. The idea has been implemented in the
framework of the Friedmann-Lemaitre-Robertson-Walker geometry in the language
of the effective action in the relativistic formalism of Schwinger's proper
time and Seeley-DeWitt's heat kernel expansion.
