A system including a conveyance system and a stored energy cooking oven. The mobile system for heating a product including: an oven including wire mesh heating elements arranged in a parallel circuit and configured to reach 1400 Kelvin in less than about 30 seconds, wherein the heating elements are shaped to include a surface radiating heat; a stored energy device configured to provide direct current to energize the heating elements; and a conveyer configured to convey the product to a heating position facing the surface radiating heat, wherein a distance of an outer surface of the product is less than six inches from the surface radiating heat.


Methods of dispersing an activation agent, nutrient, or both to a carbonaceous material to stimulate production of a biogenic gas are described. The methods may include accessing a subterranean geologic formation containing the carbonaceous material, and supplying a mixture to the formation. The mixture may include an activation agent or nutrient mixed with a dispersed phase and a continuous phase. The method may also include contacting the carbonaceous material with the mixture, and distributing at least a portion of the activation agent or nutrient over and/or into the carbonaceous material from the dispersed phase. The production of biogenic gases is increased by microorganisms that are stimulated by the distributed activation agent or nutrient to convert a portion of the carbonaceous material into the biogenic gases.


Disclosed is a mesh heating system including: two or more electrodes configured to supply a current to the wire mesh heating element; a mesh heating element comprising filaments disposed between the two or more electrodes; and a tensioner to maintain the wire mesh heating element at tension along an axis of tension as the wire mesh heating element is heated, wherein some of the filaments of the mesh heating element are disposed to intersect the axis of tension at a non-orthogonal angle.

There is provided a vapor generator including: a circuit to carry a DC current from an energy device; a wire mesh heating element to receive the DC current; and a sprayer to direct a fine spray of a liquid at the wire mesh heating element to vaporize the liquid, wherein a ratio of a resistance of the wire mesh heating element to a radiative black body area of the wire mesh heating element is less than 2 ohms/m^(2).


An isolated microbial consortia is described. The consortia may include a first-bite microbial consortium that converts a starting hydrocarbon that is a complex hydrocarbon into two or more first-bite metabolic products. The consortia may also include a downstream microbial consortium that converts a starting hydrocarbon metabolic product into a downstream metabolic product. The downstream metabolic product has a greater mol. % hydrogen than the starting hydrocarbon. The first-bite microbial consortium or the downstream microbial consortium includes one or more species of Desulfuromonas.

A method of increasing biogenic production of a combustible gas from a subterranean geologic formation is described. The method may include extracting formation water from the geologic formation, where the extracted formation water includes at least a first species and a second species of microorganism. The method may also include analyzing the extracted formation water to identify the first species of microorganism that promotes the biogenic production of the combustible gas. An amendment may be introduced to the formation water to promote the growth of the first species of microorganism, and the biological characteristics of the formation water may be altered to decrease a population of the second species in the geologic formation.

A high speed cooking apparatus employing a low voltage high current system for heating foods employing a novel wire mesh heating element. The system herein described providing the benefits of high speed cooking like that further described by U.S. Provisional Application 60/822,028 filed on Aug. 10, 2006, but yet providing significant cost benefit and simplicity over said system.


Methods are described for enhancing acetoclastic methanogenesis in subterranean geologic formations. The methods may include accessing a microorganism consortium in the formation, and assessing the consortium for acetoclastic methanogenic activity. The methods may further include modifying the formation environment based on the consortium assessment to increase methane production from acetoclastic methanogenic pathways used by the consortium. The modifications to the formation environment may include introducing an amendment and/or introducing acetoclastic microorganisms to the formation environment.
