Joshwolf shared a video My Algae Biodiesel Presentation 2 months ago

I am proposing a new solution to the algae biofuel industry. Using electrical stimulation, I have created biodiesel from algae for $0.96/gallon. Come view this presentation of my project

Gaya3 wants to discuss Arctic Sea Ice Eyed for Clues to Weather Extremes - NYTimes.com 2 months ago

Amid seesawing temperatures, suspicion is focused on the decline of sea ice in the Arctic, believed to be a consequence of the human release of greenhouse gases. - http://www.nytimes.com/2012/03/29/science/earth/arctic-sea-ice-eyed-for-clues-to-weather-extremes.html?_r=1

Gaya3 wants to discuss Rio+20 - United Nations Conference on Sustainable Development 3 months ago

Rio 20, United Nations Conference on Sustainable Development, will be held in Rio de Janeiro, Brazil, on June 20-22, 2012. The Conference will take place in Brazil in 2012 to mark the 20th anniversary of the 1992 United Nations Conference on Environment and Development (UNCED), in Rio de Janeiro, and the 10th anniversary of the 2002 World Summit on Sustainable Development (WSSD) in Johannesburg. It is envisaged as a Conference at the highest possible level, including Heads of State and Government or other representatives. The Conference will result in a focused political document. - http://www.uncsd2012.org/rio20/index.html

Badri posted a question Why is it essential to pump air and CO2 together into the photobioreactor? 1 year ago

  Following is some knowledge gained from on experimentation on algae at domestic level in PET bottles & small plastic cans. 1.I occasionally use small air pump used in domestic aquariums which gibes good bubbling air flow and costs only Rs 100 say US$ 2; 2. Conversion of algae to organic manure is quite fast (say in 1-2 Days) using associated boi-sensitiser culture made from domestic kitchen waste. Good fraction of the nutrients remain in aquas phase and appear to be very effective apparently due to aquas & micro in nature. 3. Leave tap water in a plastic transparent bottle (say of Bisrely) in sun for few days. I would observe growth of algae at bottom of the bottle which is perhaps the most prevalent in the local environment. This algae can be further multiplied in a open can left in sun. 4. Experimentation at domestic level is enjoyable like kitchen gardening. .Initially depend on physical observation.rather than chemical lab tests. Arjun

Nazry wants to know Temperature Control for a Photobioereactor 8 months ago

Hi, need some advise on whether direct cooling & heating elements is appropriate to be immersed in a 10L bubble column photobioreactor filled with microalgae? Thanks

  Your volume is tiny so the temperature stability needed to produce a consistent algae harvest from day to day will be difficult. Especially using any kind of direct interface. I recommend buying/building a small fluid-to-fluid heat exchanger out of plastic. FYI Georg Fischer Inc. manufactures a HUGE plastic heat exchanger. The total temperature swing from noon to midnight you seek to maintain is 3 deg. F. That's all you get and still have consistent algae produced from day to day.

Cll123 posted a blog Photobioreactors as adaptive shading devices 3 months ago

Since 2009 Arup Germany has been leading a research collaboration with COLT International and SSC, a small enterprise specialised in hydrobiological processes. The collaboration is about the integration into buildings of photobioreactors (PBR). The poject is funded by the initiative ZukunftBau of the German Federal Ministry of Transport, Building and Urban Development.

Gaya3 posted a blog 900 million barrels of crude to remain untouched in the Amazon 3 months ago

The Yasuni ITT initiative has been successful in collecting a sum of nearly $116 million to protect the 900 million barrels of crude oil lying beneath the Amazon Basin. This step will help in cutting down the carbon emissions which is estimated to equal the annual emission of a country like France. In addition this will also help in protecting two tribals indigenous to this region. With 90 percent of the public in Ecuador, where the oil rich basin is located, supporting this initiative, the next step of the country would be in publicising the campaign.

Kyzyl wants to know Carbon capture? 6 months ago

http://web.mit.edu/newsoffice/2011/carbon-dioxide-capture-1206.html
A new MIT study shows that, at least for the foreseeable future, proposals to capture carbon from the air are not realistic. Are you agree with this assertion?

  Under an open pounds or a semi continuous culture system, this reality is correct; mainly due to two facts: low CO2(g) diffusion into culture medium and a very high culturing area are required. But with continuous culture systems, required culture area can be reduced at least by 10 times; culture time can be reduced from 3 - 4 weeks to 3 - 4 days and productivity increased 1.5 - 2 times. All these improvements do it viable Carbon Capture.
