Abstract: A photobioreactor is provided for culturing phototrophic microorganisms comprising a plurality of reaction chambers composed of a translucent, pliable, water-impermeable material, each of the reaction chambers being an elongate sleeve capable of holding a culture medium, and a modular support structure comprising a framework defining first and second sides and a first and second end, and configured to support a plurality of horizontally oriented, vertically spaced shelves, each of the shelves extending from the first to the second side of the framework and having disposed thereon one of the plurality of reaction chambers. The design of the photobioreactor is modular, which can be expanded as needed, while maintaining the ratio of a high density of reaction chambers-to-small external footprint. The bioreactor can be used to grow single-celled micro-organisms and other small multi-cellular organisms.

Abstract: The present invention provides a photobioreactor comprising at least one translucent flexible sheet shapable by a support assembly forming thereby an elongated channel adapted for biomass production therewithin. Kits for making a photobioreactor and a floatable photobioreactor are also provided.

Abstract: An apparatus and method for producing elongate variably shaped bodies at least partially comprising thermoplastic material a profile is extruded from an extrusion system head and engaged in a flexible conduit created by cavities formed inside a series of calibration plates attached flexibly together. The calibration plates slide freely over a rotating mold to adopt the shape of the mold's outer contour. The profile is driven through the flexible conduit and winded around the rotating mould like coils. In an embodiment of the apparatus and method, the profile is winded around a size-variable mould creating three-dimensional objects in real time.

Abstract: The present invention provides a bag carrying device for a vacuum/blower device (20). The bag carrying device comprises: a bag body (10) with a bag opening (50) and a bag carrying arrangement (65) for removable engagement with a discharge portion (24) of the vacuum/blower device (20); and a bag carrying assembly with a support member (40), carrying member (80) and a securing member (120) for a shoulder carrying of the bag carrying device during collecting debris. The bag carrying arrangement (65) is to receive the bag carrying assembly. The opening (50) is to receive a discharge portion (24) of the vacuum/blower device (20). The securing member (120) is to secure the bag opening (50) around the discharge portion (24) of the vacuum/blower device (20).
