Patent number: 8938909Abstract: A simple alternative to separate filamentous bodies of Monostroma latissimum algae (large green algae) as seed stock. The filamentous bodies are easily separated and prepared for cultivation. At low luminosity (50 ?m mole s?1m?2), the filamentous bodies grow into the filamentous colony. If the filamentous colony is in turns irradiated at the luminosity greater than 100 ?m mole s?1m?2, it is turning into fronds. Thereby the filamentous bodies are evenly distributed into small segments so as to penetrate through the cotton rope for algal mass cultivation and further grow into fronds at high luminosity.Type: GrantFiled: November 26, 2012Date of Patent: January 27, 2015Assignee: National Taiwan Ocean UniversityInventors: Yean-Chang Chen, Roger Huang

Algae mass can be combined into several layers, using a binder to attach the layers to each other. A composite material of algae mass and an additive can be used and form the body of insulation panels having honeycomb-shaped chambers, which are sealed by a foil that is laminated onto the body. Various plants for cultivating algae for use in construction material are disclosed. Plants utilizing gravity harvest comprise cultivation ponds located at a slope, wherein the ponds can be opened to allow algae and water to flow downhill through a collector grill. Plants utilizing net harvest, overflow harvest or rake harvest are described.Type: GrantFiled: April 8, 2011Date of Patent: April 1, 2014Inventor: Heinz Ploechinger

Patent number: 8658421Abstract: A circulatory photobioreactor is provided. The circulatory photobioreactor comprises a first cultivating part, a second cultivating part and a pump part connecting the first cultivating part and the second cultivating part. The first cultivating part comprises a culture tank in which culture media are supplied and a first light source coupled to the culture tank, which illuminates the inside of the culture tank. The second cultivating part comprises a culture pipe placed outside of the culture tank and supplied with cultures from the culture tank and a second light source coupled to the culture pipe, which illuminates the inside of the culture pipe. The pump part is connected to both the first cultivating part and the second cultivating part in order to circulate the culture solution between them.Type: GrantFiled: July 23, 2010Date of Patent: February 25, 2014Assignees: Kairos Global Co., Ltd., Eulgi University Industry Academy Cooperation FoundationInventors: Kwang Ho Kim, Hee-Gyoo Kang, Young Il Kwon, Sun Jong Kim, Hee Joung Lim, Mi Jeong Kim

Patent number: 8658420Abstract: The present invention provides a flow-through photobioreactor containing at least one thermoplastic multi-wall sheet having an upper layer and a lower layer having arranged there between at least two sidewalls, at least one inner wall and two or more end caps. Also provided is a process for the production of a biofuel with the inventive photobioreactor. The photobioreactor and process of the present invention have the following advantages: genetically engineered microbes that give higher yields cannot escape into the environment, water in the system does not evaporate, no weeding (presence of unwanted algae), UV light from the sun is filtered out by the reactor walls, temperature control is possible, CO2 from power plants, breweries, etc. can be artificially fed to increase yield. The inventive photobioreactor is also less expensive to build than pipe reactors and may have low energy costs to operate, because little or no energy is needed for agitation and pumping in a preferred gravity assisted embodiment.Type: GrantFiled: September 15, 2009Date of Patent: February 25, 2014Assignees: Bayer MaterialScience LLC, Bayer MaterialScience AGInventors: Rudiger Gorny, James P. Mason, Glenn Hilton, Peter Schwarz

Publication number: 20140026473Abstract: A method for supplying heat energy and carbon dioxide for vegetables and/or algae production using exhaust gas. The method includes: 1) introducing the exhaust gas to a primary heat exchanger to conduct a first indirect heat exchange between the exhaust gas and air from a vegetable greenhouse and/or an algae culturing house whereby providing hot air for the vegetable greenhouse and/or the algae culturing house; 2) introducing part of the exhaust gas after the first indirect heat exchange to a secondary heat exchanger to conduct a second indirect heat exchange between the exhaust gas and outdoor air; 3) introducing the exhaust gas to a CO2 pressure swing adsorption device, separating and pumping carbon dioxide to a carbon dioxide storage tank for storage; and 4) supplying the carbon dioxide to the vegetable greenhouse and/or a carbon-absorption tank of the algae culturing house.Type: ApplicationFiled: September 28, 2013Publication date: January 30, 2014Applicant: Sunshine Kaidi New Energy Group Co., Ltd.Inventors: Yilong CHEN, Shuchuan HU, Yanfeng ZHANG
