: I'm getting 1367/4 = 342 W/m² avg for entire earth, and photosynthesis efficiency ~3%, arriving at 10.25 x 86400 x 365.25 = 323.5 MJ / year yield for each m². [[Gasoline#Energy_content]] is ~ 32.0 MJ/L (132 MJ/US gal), so that's 10.1L/m², or about 10,800 US gal / acre. I hear that efficiency goes up quite a lot when algae is fed CO2 in bulk. -- [[Special:Contributions/99.233.186.4|99.233.186.4]] ([[User talk:99.233.186.4|talk]]) 06:39, 25 May 2010 (UTC)

Note that 342 W/m² is world average. Neglecting cloud cover, irradiation in the tropics and most of continental US (except Alaska) is greater than that. Further, the review article, ''Prospective of biodiesel production utilizing microalgae as the cell factories: A comprehensive discussion''[http://www.academicjournals.org/ajb/PDF/pdf2010/8Mar/Verma%20et%20al.pdf], claims photosynthetic efficiency for micro-algae as 3..8%. Significantly, using irradiation of 342 W/m² as above, 8% efficiency would translate to an upper bound of 26.9L/m², or 28,800 US gal/acre per year. -- [[Special:Contributions/99.233.186.4|99.233.186.4]] ([[User talk:99.233.186.4|talk]]) 22:47, 25 May 2010 (UTC)

From Waste to Watts: How Sewage Could Help Fix India's Water, Energy and Sanitation Woes

From Waste to Watts: How Sewage Could Help Fix India's Water, Energy and Sanitation Woes | Anaerobic Digestion | Scoop.it
As India’s summer intensifies, many states are already in the midst of a drought—and the hottest days have yet to arrive. At the same time, water-intensive agriculture, rapid urban expansion, increases in industrial activity and growing energy production are driving the country’s water demand upward. More than half of India is now considered severely water stressed.
Part of the problem is that India still manages its water as an infinite resource on a linear model of withdrawal, consumption and disposal. But a more efficient management model is to look at water from a “circular economy” perspective. Water’s usability doesn’t need to end once it washes down the drain. Rather, we can see industrial and domestic wastewater as a valuable resource from which usable water, nutrients and even renewable energy can be extracted.

Threemile Canyon Farms leads for its sustainable practices (Opinion)

Threemile Canyon Farms leads for its sustainable practices (Opinion) | Anaerobic Digestion | Scoop.it
By Marty Meyers Nathan Donley's article ("The toxic truth behind Oregon's factory farm stench," March 24 in print editions, April 3 online) employs deceitful cherry-picking to further his agenda and make false claims about Threemile Canyon Farms. The real poison is in the Center for Biological Diversity's and Friends of Family Farmers' misleading propaganda, using buzzwords like "factory farm" to intentionally paint a tainted picture of larger dairies like Threemile Canyon Farms. I am a fifth-generation Oregonian and part owner in this large family farm. We are leaders in technology and openly share our learnings and practices with fellow Oregon dairy farmers, to benefit farms of all sizes. Here's the truth: Don't be fooled by disingenuous, cherry-picked facts about large-scale dairy farming. Anyone interested in the truth about our farm can arrange a visit to witness firsthand our significant and meaningful contributions to Oregon's dairy industry, the local and state economies, and the environment. For that reason, and despite the poisonous propaganda some would have you believe, there is room, even a need, for dairies of all sizes to positively co-exist in Oregon. Marty Myers is general manager and co-owner of Threemile Canyon Farms in Boardman. He i
