Research
One side benefit was the sequestration of waste CO2 from coal-fired power plants. The researchers were concerned with finding algae species which had a large lipid content, collecting over 3,000 North American species in their search. Work then focused on increasing their lipid content by reducing the supply of key nutrients, such as nitrogen and silicon.
Another key research aim was to validate the open pond system for mass production, resulting in the creation of 1,000 square metres (11,000 sq ft) pond systems in Roswell, New Mexico. While achieving the desired yields of 50 grams (1.8 oz) of algae per square meter per day, low temperatures were found to hamper yields.

Famous quotes containing the word research:
“To be sure, nothing is more important to the integrity of the universities ... than a rigorously enforced divorce from war- oriented research and all connected enterprises.”
—Hannah Arendt (1906–1975)
“Men talk, but rarely about anything personal. Recent research on friendship ... has shown that male relationships are based on shared activities: men tend to do things together rather than simply be together.... Female friendships, particularly close friendships, are usually based on self-disclosure, or on talking about intimate aspects of their lives.”
—Bettina Arndt (20th century)
“The great question that has never been answered, and which I have not yet been able to answer, despite my thirty years of research into the feminine soul, is “What does a woman want?” [Was will das Weib?]”
—Sigmund Freud (1856–1939)
