Biodigester Feedback:
Concerns-
- access to bottom
- leakage --> sealing top chamber
- having top chamber inside bottom [water seal?]
- funnel at top
- color? orange is +++! [Park Spark! idea]
- stick for turning/mixing
For next prototype-
- consider original model w/water seal (inside gas chamber)
- better faucet for gas --> research (?)
- rethink bottom --> easier to remove
- labels --> max. fill line, max. waste line --> see-thru? kinda?
- funnel @ top (could help direct in the materials)
