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.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
