Gaya3 wants to know EPA says palm oil does not meed energy standards. 1 week ago
"As the price of petroleum oil soars, palm oil is increasingly attractive, but the U.S. EPA has ruled that palm oil isn’t good enough to meet federal renewable fuel standards.
The proposed ruling has been called the most important climate change decision of the year. "

Baoguangzhai wants to know Algae Fuel Market Survey 2 months ago
Dear Algae group members,
We probably all know that fuel that contains algae will cost more than gasoline at this stage, so how do customers look at algae is worth thinking about. Let’s assume that we have algae-mixed diesel.I am trying to do a market survey for fuels with algae. Would you mind taking a second to fill the survey? http://www.surveymonkey.com/s/LJD7LT8
It’s just 6 questions and really quick.
Thank you very much for your help! and what do you guys think about the marketing strategy of algae fuel??? -
Deepa wants to know Why should I consider using biodiesel? 3 months ago
usage of bio diesel is deterministic in nature, people always reason out facts even though it is acceptable and may be damn good in adoption and practicing,implementation of bio diesel usage is always disputable one, so why should i consider the usage of biodiesel

Arunesh85 wants to know Why do we need biofuels? 7 months ago
Every year millions of dollars are getting invested in the field of Biofuels like Algae, jatropha, corn, etc. and still they are nowhere near replacing fossil fuels. My question is why we are investing in biofuels which compete for ground with food and pollute the world (not as badly as fossil fuels). Instead why don't we concentrate on sources like solar or wind etc?
To my knowledge, the only area where electricity hasn’t replaced fuels yet is in long range transportation like aviation, water and rail transport. Also, biofuels are made from plants that take in power from the sun, and indirectly we are cultivating the sun's energy through a long process. So instead, why don't we just harness the sun's energy in a more direct (and proven) manner?- View all 12 answers

The US Federal Governement in 2010 gave several AC of free Federal BLM land to the Nevada power company to expand one of the countries top polution sources-Ried/Gardner Coal Power Plant in Mopa Nevada. This company currently has no plans to purchase power from renewables. Thier stock price went up 100% after the land grant from the "Green Obama Administration". I would have to build an algae farm the size of Belgium to offset the increase in emissions from this huge coal plant. The land grant allows them to operate for decades more. It was a dirty deal that has caused the California snowpack to be nonexistant, i.e drought famine as I said, and impacted the snow related tourisam to our republic. If I was a wild animal I would be dead or thirsty right now. Coal -Won Renewables-Loss To top it off this plant is on the border of a sovergin nation, a native american reservation. The genocide of the red man continues Its alot more efficient than offering 10 USD for the scalp, like in the last century. Please someone take the oposing side and defend fossil fuel investment for me? NV Energy - http://www.nvenergy.com

Joshwolf shared a picture MEET LEVI 5 months ago
Through extensive testing I've performed over the last 2 months, I've concluded that the method of Low Energy Voltaic Impulse(LEVI) destroys specific protein channels along the cell wall membrane, allowing for lipid bodies (and some cytoplasmic fluids) to be secreted by the cell. By pumping this device with 120 gallons of water I was able to produce 4.35 Liters of lipid bodies which converted to 4.1 Liters of diesel fuel via transesterification. To run down 2 D cell batteries, I needed to perform this test 82 times producing just over 90 gallons of diesel fuel, and the lowest cost fuel conversion price of $0.03

Josh have you computed how many gallons of water total you would need to grow enough botryococcus for a continuous supply of ripe algae to be processed by LEVI. In other words how many gallons of water would you need to process that 90 gallons continuously?

Arunpillai wants to discuss Energy Innovations: Researcher tries directed evolution to craft better Biofuels 5 months ago
The main biofuel in the United States is ethanol made by fermenting corn. But the process is inefficient, requiring a lot of land, energy, water, and fertilizer. Turning food crops into fuels may also cause food prices to increase. And corn-based ethanol only reduces greenhouse-gas emissions by a relatively modest amount over gasoline.
The ultimate goal is to use plant waste or dedicated energy crops—plants like switchgrass that grow easily and quickly. Biofuels from these sources generate significantly less greenhouse gases than gasoline. But breaking down cellulose— the tough molecular chain that forms a plant’s cell walls—into sugars that can be fermented is complicated and costly.

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.

Donmichael posted a blog Clean Coal 6 months ago
Currently there are efforts underway to mitigate the emissions from coal firing plants by growing algae biomass which is then converted into fuel on sight or harvested and then exported to refineries. This has been going on for a few years now and this is a great idea and a currently proven and working model, except the fact that some of the originators of this business model failed to make the fuel production from the biomass cost competitive with petroleum extraction and processing. It makes sense because fossil fuels like coal and petroleum are decomposed plant and animal life that…

This begins to sound like a perpetual motion machine. The generate electricity by using algae grown from the C02 from coal fired power plants? I suggest a full energy in vs energy out analysis should be done before anyone spends a cent. There is sufficient data in Australia to show that using algae a basis for biodiesel comes out positive. But to talk about mopping up C02 from thermal power plants alone is to ignore the environmental; destruction, the gross waste of energy in delivery and the loss of lives ( I could go ). We are thinking about solving a problem by trying to fix it. We are using a century plus old system of creating and delivering energy. It is time to think SMALL and to look at ways of using distrubuted energy to its max. Leave the algae to where it works at its simplest and best. As a former director of an algal biotech company I see the world moving to a few things. Which technology "wins" to me is unimportant - the net gain - FUEL to drive agriculture is the goal. Without that we do not eat. I'm a pond man, a brine pond. I have no dount that raceways and reactors have their place but with strain selection and good husbandry, algal ponds with produce the lipid feedstock. Coal will be a valuable rersource in its own right, but NOT to burn! Its a chemically rich source that's worth saving and using to replace the feedtsock (OIL) that we consume at a rapid rate right now. Those days are numbered.

Joshwolf shared a picture Algae Lipid Extractor 7 months ago
I designed a reactor using electrical pulsing to extract hydrocarbons from the phospholipid bi-layer as well as other intercellular stored lipids. This module can process out 2 gallons of oil per hour. I'm hoping to get funds to make a larger model and achieve a goal of 100 gallons of oil per hour. This oil will be used in research testing for the creation of biodiesel fuel.

Joshwolf shared a picture Bacteria producing oils in Algae 7 months ago
As part of a project on phosphorus for my high school AP Biology class I wanted to see if you could train bacteria to eat charged phosphate groups. By adding phosphorus(donated to me from the science department) to a composter. The bacteria did indeed eat the phosphorus.
This project however was research for my separate algae project. The goal of this research was to see if bacteria could assimilate phosphate groups from phospholipids in the cell wall membrane. I have a picture of my results as what appears to be the remainder of this assimilation process, oil. I have taken samples out and performed similar chemical processi on the oil to that of waste frying oil. The product had all the characteristics, boiling, and flash points of biodiesel.
This medium presents a new foundation for bio-lipid production and a substantial price reduction to a biofuel system. I am trying to raise funds to make a 10Kg "fermentor" vessel.
