Joshwolf wants to know DRY PRESS OR ULTRASOUND-LIPID EXTRACTION? 5 months ago
I commonly use dry pressing for my oil production but I'm looking for ways to expand outside into, possibly, ultrasound or other lipid extraction methods that do not kill the algal cell.
What is the best lipid extraction model?- View all 4 answers

I know that guy personally. Nice guy! The Evodos is a very energy efficient centrifuge but i don't know how this is considered live extraction.

Robbes wants to know Why not commercial yet? 8 months ago
Guys! Why is algae fuel still not commercial? i can´t really get it. What is it that is hard at this moment? Couse getting the 1) algae, 2) salt/waste water, 3) machinery for producing seem to already be in place? What is the big problem? =)

I believe answer is simple. For one, the government has only funded research of algae biomass production rather than development of the infrastructure required to produce alga derivatives on a commercial scale. Technology has always emerged ahead of its own marketability and we are just now seeing the scarcity/demand pressures from finite fossil fuel derivatives encourage regular people and engineers to start looking for and building sustainable alternatives to fossil fuel. The ability to achieve something technologically is rarely the problem. It always comes down to cost/profit ratios. Until the technology to mass produce biofuels become cheap enough to build from the ground up investors will hold on to their money. The good news is that the time seems to be now where we can finally star breaking ground with power plant facilities we just need to raise awareness so more people will invest in the infrastructure. Also, there are state governments and DOE programs that foster new business models surrounding the new technological capacity to compete with fossil fuels and coal. Algae, in my opinion is going to be the primary energy resource used to fuel the transition from the obsolete fossil fuel infrastructure into the future sustainable infrastructure, but I also believe that this transition will be made possible because algae does not have to compete with fossil fuels. Instead, first and second generation business models for algae power generation businesses should be designed to supplement the coal and petroleum industries rather that compete with them. This way, since algae butanol or gasoline can be made to blend with petro gasoline and coal firing plants can benefit monetarily from algae based carbon mitigation as well as other polluters, investors will see potential profits with low startup cost and without the need to compete directly with powerful energy companies that are already established and hold clout in Washinton. The main problem with getting any sustainable technology on the market is that if it competes with big oil or coal it will get acquired and hidden or suppressed from the public. Funding for projects like this are rare and almost never seen. So we have to find a way to play along so everyone can make money. The coal and petroleum companies need to make the switch eventually once their resources run out so they have an interest in new infrastructure that will help them make that switch while building good public relations.

Donmichael wants to know Butanol 9 months ago
How many gallons of water is required to yield a pound of algae biomass on average with a closed bioreactor?
How many gallons of butanol can be processed from one pound of algae using tested methods?
How much co2 is needed for one pound of algae biomass?
I understand these questions are hard to answer based on algae strains but I am just looking for the the best algae strain to produce butanol or the best algae strain to produce dense cultures.- View all 13 answers

I have a vertical greenhouse design that could use some more input. I am incorporating a closed algae pond system for waste management at the base of this greenhouse which will.be powered by geothermal heat which creates steam that turns turbines for electricity generation which will be distributed wirelessly. This greenhouse will serve every societal function necessary. Food, clean water, fuel, electricty, fertilizers , production of tools and artifacts, health and medical services . Basically I want to make this a one stop unit for each large population . There is potential to make a profit for a while until of course there are enough of these towers around.the world to suffice the entire population without money or human labor. I can send you a confidential email for you to look at it if you like

Joshwolf shared a picture RECYCLED ALGAE DRYING METHOD 5 months ago
This model I made uses old pop cans painted black to dry algae. Filtered algae sludge is fills the pop cans. The pop cans then sit out in the sun for 3 hours, evaporating out the water in the algae to an 8%water content. The dry meal can be used for composters, fertilizer and diesel fuel production. (Every dry kilogram of algae has sequestered 2.2 kilograms of CO2)

Josh, great job! I'm sure there is a way to make a product with this concept but I'm concerned about the time it takes to fill up the cans. At the very least this is probably the most economical method of drying I've seen done on a small scale for individual use. Do you have plans for scaling up as a waste processor from continuous production? That way you would have a continuous waste of sludge. How long did it take to get all that sludge and what is the ratio of sludge to your primary deisel production in the same amount of time? @Woolncathairs, after the algae is dried, the oil is pressed out with a screw press, and the rest is then heated out. Or... Flash pyrolysis is an energy intensive method that converts algae paste directly into bio crude which then is converted into b100 diesel through transesterfication then is cleaned if needed. Transesterfication is the most used method after pressing as well. However, the best way to get oil out of algae is through live extraction or "milking" which basically sucks the oil out of the algae without harming them. The oil then floats to the top which can then be extracted and processed, and the harvested algae sinks to the bottom where it can be taken back into the bioreactor to regrow more oil. This is way more efficient than batch processing which kills the algae. Batch processing may be good for some applications let's say if you want to extract proteins, carbohydrates and fats for multiple uses; but this is energy intensive because you have to dry the algae to get the products out which also requires various separation methods. To avoid the cost of separation and processing with batch harvesting, it is a good method to produce a high BTU biomass to burn for steam power in a coal plant (the waste heat from the plant can be used to dry the algae) but not for applications that target one needed product like oil. This is also due to the fact that a batch of algae killed requires a batch of algae born, and regrowing new fat cells is way less energy intensive than growing a whole new body. Compare it to telling a fat person to go get fat again after lyposuction; to killing a fat person and telling his friends to have a bunch of kids to grow up and replace him. If you're going to do any research at all it should be on milking oils, carbs, and proteins for specific applications at their point of use to minimize transportation cost. That is one way to undercut fossil fuel prices because fossil fuels cannot be cultivated anywhere and therefore require a large transportation infrastructure. Also, in regards to the drying method. Once you press out the oils the rest is fermented to get alcohol out of the sugars while the protein is used as feedstock and the waste from fermentation is used for fertilizers. There is a wide range of uses for that waste though instead of just fertilzers, like recycling it back into the system as algae fertilizer or used for processing, for better energy conversion.

I think both of these extraction methods are obsolete due to new innovations such as one step hydrolysis and one step bacterial conversion methods.
-
The team from the Tulane University calls their new bacteria TU-103, and it is apparently the first bacteria found in nature that can convert cellulose directly into butanol. Meanwhile, researchers at the U.S. DOE are developing another biofuel microbe that can produce butanol from waste material, including agricultural waste.

Biosyncrude from Pyrolysis - A new process breaks down wood, straw, or other plant waste by a process known as bioliq. It yields a number of fuel products that could be refined, to produce gasoline, as well as other useful chemical byproducts. The process starts with pyrolysis -- heating the plant waste in a vacuum chamber to 500?C. A thick liquid called biosyncrude, containing solid particles of coke, is produced. - http://www.dailytech.com/article.aspx?newsid=14111
