After estrification v r collecting the hexane layer for analysis the FAME for GCMS.. if they any need to evaporate the hexane... if no need to evaporate..what about the hexane content ... pl can u clarify me ?
This was what I read about Joule Technologies
Joule Wins Prestigious Wall Street Journal Technology Innovation Award
CAMBRIDGE, Mass., Oct 18, 2011 (BUSINESS WIRE) -- Joule today announced its recognition as the 2011 Wall Street Journal Technology Innovation Award Winner in the category of Energy, chosen for its transformational approach to highly-efficient renewable fuel production. In addition, Joule received the Silver award across all of the competition's 16 categories, for which there were over 600 entrants from around the world.
"We are honored to be the Wall Street Journal's choice for the most innovative energy company, and to be recognized even beyond our industry as one of the world's top innovators overall," said Bill Sims, President and CEO of Joule.
"We started with a big idea -- the direct conversion of sunlight to fuel without raw material feedstocks -- and four years later we've proven the process, optimized the technology, built a strong patent portfolio and laid the groundwork for commercial production to begin in 2013. We will bring much-needed scalability and infrastructure-readiness to the renewable fuels space, with a platform that can yield multiple products, including valuable, fungible diesel fuel vs. a blendstock like biodiesel. We appreciate this recognition of our company's efforts to successfully innovate outside of today's common 'biofuel' definition," said Sims. "
Now, what had puzzled me about Joule Technology's concept "the direct conversion of sunlight to fuel without raw material feedstocks"...this appears to be an exaggeration because they are using cyanobacteria as an agent, and as we all know, cyanobacteria is an algae. So, they cant claim they are not using any feedstock...at least this was my idea about what the company did until a few months back...does anyone have any other opinions about Joule?
It will be great if they have been indeed produced a breakthough, but I am not sure of that
Some really cool and excellent inputs

3. Development of symbiotic communities of enhanced organisms.
4. Off-the-shelf parts inventory in synthetic biology.
5. Shift from freshwater to saline water.
6. Rooftop bio systems.
7. Super-light, super-strong materials.
8. Bio-processors built into biomass.
I read this recently @ CleanTick news - http://www.cleantick.com/portal/news/pages/955
Aquaflow Bionomic Corporation has signed a deal with the CRI Catalyst Company to produce commercially viable cellulosic hydrocarbon fuels and blends.
CRI had acquired the Integrated Hydropyrolysis and Hydroconversion technology (IH2) earlier this year. Aquaflow’s algal capability and this technology will be testes and evaluated as a part of the agreement.
IH2 is an advanced pyrolysis technology which will utilize low pressure hydrogen together with a catalyst to convert biomass cost-effectively into renewable gasoline, diesel and jet hydrocarbon blend stocks."
So, this is essentially hydrocracking, right, whatever fancy terms that CRI uses for the same thing? And what do you think of such a method? This involves the extensive use of hydrogen, so that could result in significant increase in costs?
Any intelligence on the suitability (technical and economic feasibility) of hydrocracking / hydroprocessing of biomass (especially algal biomass) will be very interesting
The major drawback in using switchgrass for commercial scale production of ethanol is the plants succeptiblity to pests, fungus and weather conditions. Are there any ways to improve the recalcitrance of Switchgrass?
Vinaytakbhanu posted a question I recently came across a very surprising fact that it is possible to estimate the dry weight of Arundo donax from shoot length. Is it really possible to make such a computation? If so, could the same concept be expanded to other bioenergy crops? 6 years ago

Legislation can’t change the fundamental laws of science.
Although a lot of hard work, creativity and significant investment are being applied to making these advanced biofuels today, there are currently no technology pathways that can deliver the volumes required by the current or future year mandates. The gap between policy and technology is huge.
The world’s most powerful armies are going green and reducing dependency on fossil fuels seems to be their main objective. The United States armed forces, one of the largest single energy consumers, are looking at renewable jet fuels for aircraft that use algae or vegetable and animal oils. Almost all fighter planes of Britain’s Royal Air Force have been certified to fly entirely on bio-fuels, when they are available, and researchers are looking into solar-powered unmanned attack aircraft. Taking a cue, Indian armed forces too have embarked on a drive to save fuel - http://www.financialexpress.com/news/Soon--green-fuel-for-military-vehicles/857858/

I never paid any attention before to how the local filamentous algae behaves as winter aproaches.
As the temperatures are dropping into the 40s F and the days grow shorter, the algae is breaking down and dissapearing. I notice that this is happening to algae growing in tanks in my house also, so it must be primarily the length of daylight that is doing it.
Indeed, I noticed earlier that a tank that was producing a lot of algae quit growing when the window light was blocked from it for a few weeks.
In my observation, light is the single most essential element in this Iowa filamantous algae maintianing healthy growth. Then would come fertilizer, which could be most any organic pollutant, like a bit of dung or bits of people food scraps.
I suspect temperature is probably less important, so long as it remains above freezing.
This algae always appears again quickly in spring, so it must regrow from some kind of spores or fragments that withstand months of freezing.
I was able to mail a small sample to India, the cost was only about a US dollar for postage, so it was insignificant. It took a bit over a week to make the trip.
Now the challenge for the folks working with it will be making sure it gets enough light to keep growing.
A team lead by George Huber from U. Mass, Amherst and Charles Wyman from the University of California, Riverside (and a co-founder of Mascoma) earlier his year reported in the RSC journal Green Chemistry on an integrated, two-stage aqueous phase hydrodeoxygenation (APHDO) process for the production of high-octane renewable gasoline from maple wood (as a representative of lignocellulosic biomass).
Despite struggles, next-gen biofuels continue to find funding
The LanzaTech process increases industrial energy efficiency by capturing waste gases (CO, CO2) and converting them to valuable fuels and chemicals through its microbial gas fermentaion technology. The LanzaTech process is feedstock agnostic and is not dependent on any one resource for gases. The LanzaTech process has already been proven utilizing steel mill off gases as well as synthesis gas derived from biomass. This means that all synthesis gas is a suitable feedstock including gases derived from coal, petroleum coke, natural gas, municipal solid waste etc.
Researchers from University of KwaZulu-Natal with the aid of the municipality plan to start a plantation project for moringa oleifera The plan is to use emerging small-scale farmers to harvest the pods for biodiesel.
The Moringa oleifera, commonly referred to as the " drumstick tree " or "mother's best friend" in many cultures, is native to northern India and ancient Ayurveda medicine claims that it prevents 300 diseases. Moringa seeds are extremely high in oil and "the tree can survive in relatively unfavourable conditions and does not require sophisticated and expensive farming methods or inputs.
Startup by 4 IIT students named Sea6 made into the Economic Times headlines for their breakthrough achievements in harvesting fuel from seaweeds. I recommend alternate energy enthusiasts to go through the links mentioned below.

Biofuel Boom in Aviation
Last week, a Boeing 747 made history by flying across the Atlantic with all four of its engines powered by hydroprocessed oil from camelina, a biofuels crop. The European airline carriers KLM Royal Dutch Airlines and Lufthansa, Germany's national carrier, also plan to use hydroprocessed oils as their biofuel source. European regulation limiting carbon emissions have increased demand for biofuels in the aviation industry.
