The Inspiration


Milk Collection Process


Hour 3 Hour 2 Hour 1 Hour 4

Milk Local Transport Limited Milk Supply (No access to remote

dairy farmers)

Lower Quality (High Bacteria Count)

High Transportation Cost

(Multiple Trips)

Village Collector Truck Driver Dairy Processor Dairy Farmer

Bacterial Growth over time

Milk Collection Racing Against Time

Start-‐up Thinking

1. Beware the Voice of the Customer

2. Funding as system input & project milestone

3. Optimize for minimal set of viable features

4. Pivoting is essential; system boundaries are flexible

5. Stay focused on the problem, not the solution


Unreliable Electricity

in Villages =

Low Milk Quality and High Transportation Cost

Current Solution: Diesel Generator


Unreliable Electricity in Villages

= Low Milk Quality +

High Transportation Cost


Our Solution Cool Milk with 5 Hours of Grid

Rapid Milk Chiller Rapidly cools milk from 34 °C to 4 °C

Thermal Energy Battery 5 hours to charge Can cool 500L milk
