Large-scale open ponds for growing micro-algae are one of the methods used by Cellana at its Kona, Hawaii demonstration facility for achieving the production of consistent, high-volume, commercial-scale feedstock. The six-acre plant has grown more than 20 metric tons of whole algae biomass since it opened in 2010, using the company's ALDUO commercial-scale, two-stage outdoor process. (Source: Cellana)
What is the local enviromental impact of this refinery? Are coral reefs in jeopardy due to water run off? Does the island smell like diesel or a sweet swampy smell from healthy algae lagoons? Only ask because every underwater film I have seen in the past 10 years of the Great Barrier Reef off of Australia alwasy shows what they believe a few degrees difference in water temperature can do to a coral reef.
AnandY, there's a lot of info about this topic on the web in several locations. The answer, of course, is "It depends..." on various variables. You might want to start with the link given in the article for the research center.
What are the green house effect of producing algae based biofuel? Whether the carbon required for biofule generation, captured from power plants and oil refineries? Is there any effective way to bottle releases from industrial sources?
The Solar Biofuels Research Centre in Brisbane, Australia hosts one pilot project run...
Australia also has geographical advantages such as long coastlines and large, flat deserts in the interior under year-around sunshine and stable atmospheric conditions. Given these factors, Australia is one of the best places to grow marine micro-algae for oil extraction.
The growing energy demand cannot be satisfied solely by relying on fossil fuels, as fossil fuels will eventually become depleted. Algae based fossil fuel will be one of the best solution for world's energy requirements.
How 3D printing fits into the digital thread, and the relationship between its uses for prototyping and for manufacturing, was the subject of a talk by Proto Labs' Rich Baker at last week's Design & Manufacturing Minneapolis.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
