MIT D-Lab Fuel & Cookstove Testing Facility - The Burn Lab (MIT Building N52-388)
Among 3-D printers and electric go-karts in MIT Building 52 is D-Lab's fully-functional, custom designed test hood for controlled performance testing of bimoass fuel and stove technology. The facility is set up to run standard Water Boil Tests with real-time fuel mass loss and combustion emissions measurement.

While testing at MIT D-Lab offers control, replicability, and comparison with other facilities, testing in real conditions with real users is the true indicator of product performance. Our Mobile Lab consists of most of the same equipment in the D-Lab Fuel and Stove Test Facility, but portable can be packed in five suitcases, and assembled on-site in about 30 minutes.

The Mobile Lab offers a useful benefit in that we can apply a rigorous lab-based method, in a kitchen setting with real users. However, transforming a user's kitchen into a lab can be stressful, inconvenient and uncomfortable. Therefore, in close collaboration with Sensen, we are developing remote monitors which use low-cost sensors, dataloggers, and mobile communications technology to evaluate cooking products during real use conditions in an arrangement that users are comfortable with.

Since one of D-Lab's main focuses is on alternative biomass fuels, we do a good deal of work on methods for using waste biomass to produce clean fuels. One process for increasing the value of waste is carbonization and briquetting. We evaluate the efficiency and emissions from different methods of charcoal-making in an effort to provide on-the-ground producers with data to help drive their decisions. We also perform fundamental research on biowaste pyrolysis processes using advanced analytical methods.

DIY Data Acquisition
Description: When we do testing at D-Lab, we often wonder "How do these devices work, and could I make something that better suits my needs?" During testing, we amass large amounts of data from different instruments and quickly becomes overwhelming to organize and make sense of. In the spirit of open-source and DIY, we are developing a simple Arduino- and Processing-based platform for acquiring test data so that it is convenient to work with post-testing. Stay tuned for Instructables!
