A method and a system for producing a change in a medium disposed in an artificial container. The method places in a vicinity of the medium at least one of a plasmonics agent and an energy modulation agent. The method applies an initiation energy through the artificial container to the medium. The initiation energy interacts with the plasmonics agent or the energy modulation agent to directly or indirectly produce the change in the medium. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the plasmonics agent or the energy modulation agent.

An invention is provided for conversion of methane into hydrocarbon fuels is disclosed. The invention includes providing methane to an illumination chamber, and illuminating the methane with substantially narrow bandwidth photons of a predefined wavelength. The photons are provided from a substantially uncollimated light source producing photon intensities less than 10 Watt/m.sup.2. As a result, the methane is placed in an excited state that results in the molecules of the methane reacting more readily with other molecules to form a final product.
