Orlando NBC station WESH has a report and video segment online detailing the work of a group of UCF students that are converting used Chick-fil-A grease into biodiesel via an Appleseed processor. The students also donate 20% of their processed fuel to the university for their use in dozens of on-campus diesel vehicles. The story notes the requirement to pay Florida state fuel taxes on home-brewed biodiesel. Overall a pretty accurate report.
Example of content:

They have been draining smelly fryer grease and feeding it to their bio-diesel reactor -- a fancy name for a water heater, some pipes, valves, hoses, and filters that turn grease and two household chemicals into fuel. The newly formed fuel powers their diesel engine cars.

"To make a gallon of bio-diesel, it's about 80 cents," UCF student Michael Schulist said.

Not only cheap, the muddy looking bio-diesel burns cleaner than its petroleum-based cousin.

"Petro-diesel is a very dirty fuel. This is a very clean burning fuel," Schulist said.

It produces less CO2 -- the main threat to our climate -- than gasoline or regular diesel.

"It would limit the amount of pollution we put into the air but it would also save a lot of money," UCF assistant professor Ali Gordon said.

Two biodiesel powered sojourns kick off this weekend:

• Earthrace - the biodiesel powered boat we've written about before kicks off their second attempt at breaking the world circumnavigation record. This time they are leaving from Spain, heading West through the Straits of Gibraltar, to the Panama Canal etc. They hope to beat the current record of 74 days, 23 hours and 53 minutes. We wish them a safe journey!
• The Dirty Hands Caravan, a string of biodiesel powered buses, leaves from the Coachella Valley Music & Arts Festival in Indio, CA with plans to arrive on May 4th at the New Orleans Jazz & Heritage Festival. Volunteers can register to take part in the caravan and will volunteer at local organizations along the way. Safe travels to these participants also!

The Sierra magazine environmental advice columnist Bob Schildgen (aka Mr. Green) has compiled advice on a wide variety of topics, including biofuels, in a new ~200 pg. book - "Hey Mr. Green". Just to double check - I first made sure the book was printed on 100% post-consumer waste - yup. The book is organized into 5 sections based around the topics Home, Food, Fuel, Recycling, and The Big Picture. Each section has an introductory essay followed by a selection of questions and answers from the column. The author consistently injects humor and erudition into the answers, while keeping a central theme of conservation humming in the background. 15 pages of end notes provide references for the facts and figures used in the answers.
The main message of the Fuel section is to reduce the use of cars - as he writes "Carbon-free doesn't beat car-free". I found the explanation of how 100 gallons of fossil fuel turn into 2000 pounds of CO2 easy to follow. Living on the Space Coast, the question and answer about private space travel was thought provoking. A question about the green-worthiness of a biodiesel powered Jeep Liberty CRD elicited a reasoned response beginning with:

"Biodiesel is a good choice for many drivers: It pollutes less than ordinary diesel fuel and generates a lot less globe-warming carbon dioxide than gasoline does."

That advice is tempered with the caution that

"it's a big mistake to think [biodiesel] is a 'perfect solution' to our energy problems."

He goes on to explain the limits of farmland fuel production in this country. In another answer to an ethanol question a bigger picture solution is offered:

"What we really need is a crash program for efficient mass transit, stricter fuel-economy regulations, and a serious commitment to developing solar, wind, and tidal power. In addition, a vast amount of energy could be saved if we all reduced our car use; made our homes as energy efficient as possible; and stuck to the speed limit when we do drive, making sure our vehicles are well tuned and our tires properly inflated."

Other questions answered in the book range from birth control to burial methods, always answered in an intelligent non-preachy way. An enjoyable green read.

As a follow-up to the FIT talk from today I wanted to post some notes. The key points I picked up:

• Open raceways are the only possible cost effective way to produce oil from algae. Closed systems (Photobioreactors - PBRS) are relatively costly as they must try and solve temperature and degassing problems.
• There are lots of estimates on oil production values from algae, but until real world production is in place, the high side numbers are fantasies.
• CO2 and Sunlight are not really free inputs. CO2 *costs* from $50-$400 per ton. It takes 2 tons of CO2 to produce 1 ton of biomass.

Dr. Weissman, who worked on the DOE Aquatic Species Program (ASP), covered a lot of ground, from some work in 1953, up through the current work FIT is performing (under a $415K grant from the State of Florida Farm to Fuel program). He showed a picture of PBR's on the MIT roof from 1953! Much of the information being patented today seems to be covered in that decades old work such as In Algal Culture: From Laboratory to Pilot Plant.
With genetic engineering, today's algae can be improved in several ways. Dr. Weissman mentioned modifying the reaction area such that "longer antennae" are used for photosynthesis. These cyclotella mutants use 20 chlorophyll instead of 200 as their light processing engine.
In the current FIT project, smaller tanks have been running with cultures in Vero Beach for almost a year - 1/20th acre raceways are about to come online.

Brevard Biodiesel will be taking part in the 4th annual "Goby Fest" presented by the non-profit Coastal Preserves Alliance.
The event takes place at the St. Sebastian River Preserve State Park on Saturday April 5th 2008 from 10am til 4pm. This nature festival raises funds to support local state parks and aquatic preserves. Highlights include various kayak/boat/wagon/walking tours, blacksmith demonstrations and a herpetological display. Food and craft vendors will be present along with other exhibitors. Admission is free with a nominal charge for tours.

This 22,000+ acre preserve is the largest upland public property in the Indian River/South Brevard counties region. There are many opportunities for wildlife viewing in the area including chances to spot nesting bald eagles, kestrels, shrikes, and many other feathered visitors - earning their spot on the Florida Birding Trail.

We'll be there to share information about biodiesel - have fun!
