The Bouillante geothermal field presently provides about 8% of the annual electricity needs of the French West Indies island of Guadeloupe. It has been the subject of a large number of studies covering various disciplines. These results enable the proposal of a hydrogeological conceptual model of the field. The reservoir consists of two perpendicular sets of fractures and faults, related to maj...

In this Letter we show that by appropriately providing an auxiliary "dress" beam one can extend the longevity of an optical filament by almost one order of magnitude. These optical dressed filaments can propagate substantially further by judiciously harnessing energy from their secondary beam reservoir. This possibility is theoretically investigated in air when the filament is dressed with a co...
