Brane cosmologies with static, five-dimensional and Z_2 symmetric bulks areanalysed. A general solution generating mechanism is outlined. The qualatitivecosmological behaviour of all such solutions is determined. Conditions foravoiding naked bulk singularities are also discussed. The restrictions placedon the solutions by the assumption of such a static bulk are investigated. Inparticular the requirement of a non-standard energy-momentum conservation law.The failure of such solutions to provide viable quintessence terms in theFriedmann equations is also discussed.Comment: 15 pages, references added, minor change
