Publication number: 20140030801Abstract: The invention relates to a reactor for growing algae in an aqueous liquid using photosynthesis. The reactor includes a tank for accommodating the aqueous liquid with the algae in it, and a lighting system including a light source with a plurality of LEDs, a mounting structure for supporting the LEDs, and a housing for accommodating the light source and the mounting structure. At least a portion of the housing is transparent for light emitted by the light source. The lighting system is at least partially submerged in the aqueous liquid. Additionally, in operation, the light transmitted through the transparent portion of the housing is of sufficient intensity to substantially prevent growth of the algae on the surface of the transparent portion of the housing.Type: ApplicationFiled: September 19, 2013Publication date: January 30, 2014Applicant: Tendris Solutions B.V.Inventor: Taco Wijnand NEEB

Publication number: 20130102069Abstract: The invention relates to a method for transferring light generated by a light emitting diode towards an aqueous liquid containing algae. The method includes emitting light by the light emitting diode having a first refractive index, transferring the light through a liquid medium having a second refractive index, and a solid medium having a third refractive index, into the aqueous liquid having a fourth refractive index. The value of the first refractive index is equal to or greater than the value of the second refractive index. The value of the second refractive index is equal to or greater than the value of the third refractive index. The value of the third refractive index is equal to or greater than the value of the fourth refractive index. The invention further relates to a reactor designed to perform such method.Type: ApplicationFiled: December 7, 2012Publication date: April 25, 2013Applicant: TENDRIS SOLUTIONS B.V.Inventor: Tendris Solutions B.V.

Publication number: 20120129245Abstract: The invention relates to a lighting system for illuminating algae in an aqueous liquid. The lighting system includes a light source comprising a plurality of LEDs, a mounting structure for supporting the LEDs and a housing for accommodating the light source and the mounting structure. At least a portion of the housing is transparent for light emitted by the light source. The housing is at least partly filled with a cooling liquid, such that, in use, heat from the LEDs is transferred by the cooling liquid from the LEDs by means of convection. The invention further relates to a reactor comprising such lighting system.Type: ApplicationFiled: January 30, 2012Publication date: May 24, 2012Applicant: TENDRIS SOLUTIONS B.V.Inventors: Taco Wijnand NEEB, Johannes Otto ROOYMANS

Publication number: 20100243033Abstract: Disclosed is a photovoltaic laminate comprising a photovoltaic semiconductor material. The photovoltaic laminate may be manufactured without the use of adhesive, thereby avoiding light loss through absorption by an adhesive layer. The laminate may be formed by forming a sandwich of the crystalline semiconductor material between layers of non-crosslinked cross-linkable polymer, followed by in situ cross-linking of the polymer. The laminate may be incorporated in a curved surface of a structure, such as a boat hull or boat deck.Type: ApplicationFiled: December 3, 2008Publication date: September 30, 2010Applicant: TENDRIS SOLUTIONS B.V.Inventors: Jeroen Brouwer, Ramon Philippe VAN DER HILST, Taco Wijnand NEEB

Patent number: 7632061Abstract: A pump or turbine is disclosed which includes a housing provided with at least one chamber, a rotor, which is rotatably mounted on a shaft in the chamber, an inlet, which communicates with the chamber at least at the location of the shaft, and an outlet channel, which communicates with the chamber at least at the periphery of the rotor. The pump or turbine moreover comprises at least one bypass channel, a first end of which opens into the outlet channel of the pump and a second end of which forms an inlet. The bypass channel may be used for increasing the propelling force or for pumping slurries, for example.Type: GrantFiled: August 26, 2005Date of Patent: December 15, 2009Assignee: Tendris Solutions B.V.Inventors: Taco Wijnand Neeb, Johann Hennig Schreuder
