Vacuum energy is understood by one-periodic frequencies with apossible lowering by confined Casimir forces. Doubly-periodic processedvacuum energy is a non-stationary energy state of a complexLagrangian. Its is suspected that a doubly-periodic processingin the vicinity of zeros of zeta functions lowers vaccum energyas compared to a real physical field. This quadratic modelcompensates positive energy of molecules mainly by dark, complexphantom energy and negligible ion energy. A proposed doublyperiodicsynthesis gains cooling energy by a minimum amount ofenergy. Created matter is a zero-energy state of biomass anddark energy which is capable to compost into a zero-energy state.
