UV-Tube Design

Identified design that:
•
•
•
•
•
Kills bacteria (in lab & field)
Isn’t too toxic
Can be built with local materials
Is affordable with local income
Is ugly (but probably can be beautified)
4
My take
• Focused on technology, not real-world
impacts
• Ultimate public-health impacts unknown
• Very little market research
• How adaptive can the design be?
• What are the barriers to dissemination?
• Why aren’t the designs and results online?
