Abstract
The production of biomass, such as algae, is carried out in a substantially transparent tube wound on an upstanding core structure. The exterior surface of the tube is exposed to natural light and the tube and/or the core is adapted to encourage light penetration into the tube in the region of contact between the tube and the core structure.
