Team Vision for Final Demo and Handoff
- During this final phase, the team planned to finish
all integration and subsystem testing, in addition to
system testing and extraction of thermal
- The team in reality did finish integration, calibrated the test and model, and found the thermal conductivity of biochar.
Test Results Summary
In calibrating the heat transfer model, Owen’s
Corning R250 Insulation was made into a cylinder and
implemented into the system. This R250 insulation has a
characteristic R value of R5 per inch, so with a
thickness of 1.4 inches, the expected R value would be 7.
The actual R value received was approximately 6.9.
Knowing that the R value of high end concrete is 1.5, biochar was found to be 1.7 and therefore a better insulator.
In testing for changes in relative humidity, the interface asks for you to set your desired level of ambient humidity (~90%). Once the ETC reaches the desired level, the test initiates and runs for approximately 2 hours.

Recommendations for future work
- In utilizing the test rig created by this project, it
is recommended that the user only use molds provided that
integrate easily with the test chamber.
- It is strongly recommended that the user closely
follow the user manual in operating the ETC.
- Further, it is strongly suggested that the user
implements a vibration table in the mixing of the
concrete to mitigate heat loss in thermal conductivity
testing and to decrease the amount of pores for humidity
- It is possible to expand upon the test rig to include
wet wall, evaporative cooling on the half, hollow sphere
