Marc in the wild. There were many arguments about whether the emissions from the stove in the picture (which burns Jatropha seeds) were toxic.
Marc presented our work as part of a talk on rice husk in Kirkland last weekend. Check out the full slides on slideshare.
Thank you
Thank you. As long as it is, this list is probably incomplete.
Dr. Colton - for the constant challenge to be more rigorous, more precise
Prof Khan (Sabir) - for the encouragement of creative chaos and design thinking
Tim Sewell - for the time in his workshop and always being available to answer our (sometimes silly) questions
John Bland
Dr. Paul Anderson (Doc TLUD) - for inspiration on many occasions.
Baxter
AE Combustion Lab
COA - for letting us test outside their building all semester
The ID shop - for the slightly dangerous cutting they helped us with
Courtney
Christian
and the rest of Engineers Without Borders
Dr. Paul Olivier
Dr. Alexis Belonio
Andrew from the junkyard
Melissa - for sewing a button back on one day in studio
The professors in ME and ID that provided constant critical feedback.
and everyone that kept us company outside while testing all semester.
and everyone that came to our table at the Expo. Hope you enjoyed the hot chocolate.
Results from the ME expo. Our project was featured in the Daily Digest before the contest, too.
Big list of thank yous coming soon…
Monday, 12/6: we finally manage to overpower the stove. It took just two small changes to go from a smoke producing trash can to a goblet of fire.
A Saturday at Tim’s shop with the team to produce these cylinders for the final prototype.
Jimmy, Isaac, and Marc bled a bit during the process. Friends at Aprovecho told us it takes at least 50 cuts before you’re considered a real stove designer. 44 more to go.
Big thanks for Baxter at Diamond Roofing for the material and help rolling the cylinders.
Some brilliant tin-can engineering by Isaac has finally managed to turn rice husk into cooking heat. We got an amazing 25 minutes of unattended run time. This far exceeded our goal of 10 minutes.
Thanks especially to Dr. Paul Anderson (Doc TLUD) for inspiration. The design arose out of discussions during his visit 3 weeks ago.
Lighting the stove could be easier. We think the secondary air is choking the initial pyrolysis flame.
Also, we need a cooking surface appropriate for rural Nicaragua. Designs in the works…
I spy Jordan, Isaac, Marc, Tim, and lots of interested faces. The rest of the set on Dean’s Flickr. (thanks!)
