We have a roof over our heads and we’re ready to make biodiesel! Read on to see what the IBP team accomplished this past week in paradise.
We presented our project to Nosara Sostenible – a committee of like minded individuals (business owners, teachers, etc) in the community who are dedicated to making Nosara a model for sustainable development for the rest of Costa Rica. A couple more restaurants are interested in joining the program and Jessica (teacher from the Del Mar Academy) will include our project in her talks to the community about the new recycling center and to include their used cooking grease when collecting/sorting their waste! Tuesday was hectic at the Casa Tucan. Channel 7 News, one of Costa Rica’s national tv channels, filmed their latest story about the thievery issue in Playa Pelada (Nosara) at the Tucan and tons of people from the community came to be interviewed. There was also a major plumbing issue at the hotel so Rigo and Ivan couldn’t help with the construction of the shelter. Ryan and I went to the hardware store and purchased two clear 50 gallon drums (one for ethanol storage, one for biodiesel storage) and a 120 gallon wash tank (the last step in filtering the biodiesel by washing the remaining particulates out of the fuel).
Wednesday was a productive day: we finished the roof; started the ethanol fermentation; collected more grease; received our biochar stove; and made the greywater filtration system.
I made our greywater filtration system, which is fairly easy. This is where the water from the wash tank will be deposited after its been used to filter out the last of the particulates in the biodiesel:
Tyler flew to San Jose to have surgery on his knee Thursday so we watched his house for a few days.
Rigo and Ivan worked on the garden at the Tucan so Ryan and I made a trip to the hardware store to buy copper tubing for the biochar heat transfer system and the bubble coil in the wash tank. I began permanently securing all the pieces of the system into the ground with rebar and cinder blocks (we only had to buy a few more cinder blocks, the rest were old ones we collected from the Tucan and on Tyler’s property). Friday, we finished stabilizing all the parts of the system with rebar and cinder blocks while Ryan continued to work on the pump with the water heater, the methoxide tank, and the WVO tank.
Rigo built a desk and a shelf with all the scrap wood lying around Tyler’s property and what was leftover from the construction of the shelter.
We dug the trench for the underground copper tube that will transfer heat from the biochar stove to the WVO tank through a coil system. On Saturday, Ryan said he a needed a day to himself without any distractions (construction, hardware store visits, miscellaneous hotel issues) to finish testing and making the first batch of biodiesel the old fashioned way before we start to add the “innovative” parts to the system. Ryan tested the water heater and the pump with a 5 gallon pechinga of WVO and wrote 5, 10, 15…30 gallon marks on the tube that feeds into the water heater tank so we know how much WVO is being mixed with the ethoxide before we start pedaling the greasercycle.
We went to the rodeo that night in Garza (one beach town south of Playa Guiones) to experience the local cowboy culture and have a break from work. Check out Safari Surf’s new blog series “Inside the Peak” for more photos and stories from the past week thanks to our new social media man behind the scenes, Nick.
We woke up to destruction Sunday morning as unprecedented gale-force winds had ripped through Nosara. The Casa Tucan had a few fallen trees and the power was out so I walked down to the beach to see what the offshore winds were doing to the waves.
That afternoon, the wind died down a little bit and two clients that had booked the voluntourism package I created for Safari Surf, called the Sustainable Surfer Package, wanted to see the “Innovative Biodiesel Project” and Ryan and I wanted to make sure it was still there! Megan and Lauren were impressed and Ryan and I were relieved to see that everything was still in tact – it was just covered in branches and leaves thankfully. If our shelter and biodiesel system can withstand the strongest winds to ever hit Nosara, then we are in good shape. However, the news says this wind storm will be here for two more days and we have a lot to get done so hopefully it doesn’t slow us down too much. Ryan’s batch of biodiesel that he started to make Saturday has been pushed back another day due to the harsh winds on Sunday and the Harbor Freight drill pump failing to pump the methoxide into the water heater (even though the pump is supposed to be resistant to chemicals, it seized up so we’ll have to use the red hand pump). Come back next week to see the “Innovative Biodiesel Project” complete! Rigo’s friend who is a welder is helping us put together the greasercycle system. We have 7th graders from the Del Mar Academy coming on Tuesday to learn about the whole process. We will finish enclosing the shelter with a fence and a door and the appropriate safety signs and we are tossing around ideas for the plaque so we’ll have that up this week as well. (People expecting post cards as a “perk” for donating – you should have them in the next week or so!)
