Abstract:
1. A storage device for the preservation of oxidizable materials comprising: a storage chamber enclosing a storage space where oxidizable materials may be placed; a differentially permeable membrane, said differentially permeable membrane allowing at least one selected gas to pass therethrough while inhibiting at least oxygen from passing therethrough, said differentially permeable membrane in fluid communication with said storage chamber such that the at least one selected gas allowed to pass through said differentially permeable membrane flows into said storage chamber; an air mover for feeding gases to said differentially permeable membrane; a piezoelectric or Peltier module for cooling the temperature within said storage chamber below that of the ambient temperature surrounding said storage device; and wherein the level of oxygen within said storage chamber is reduced relative to the level of oxygen in the atmosphere and is maintained in a range of about 4% to about 6%.
