Several method of Microwave assisted extraction of oils that we will use on oil/tar sands and/or refuse plastic and/or rubber (eg. tires), bituminous coal, and/or biomass, and/or kerosene and/or naphtha and/or propane and/or oil/tar sands with corn, eucalyptus, oil palm, and coconuts, maize, jatropha and other possibilities algae bagasse, miscanthus, sugar beet, sorghum, grain sorghum, switchgrass, barley, hemp, kenaf, potatoes, sweet potatoes, cassava, sunflower, fruit, molasses, corn, stover, grain, wheat, straw, cotton, other biomass. One method/process add a non-aqueous organic extractant to the source materi al (with a some content that absorbs microwave radiation and mixing it with a solvent that is transparent to microwave radiation) and there is our newly invented tumbler to expose the mixture to microwave radiation. Then suddenly raise the temperature via microwave, cool it down (that is has a more concentrated source of volatile oils), add more source material and alternate back and forth (heat - co
