Status at End of Fall

• Heat Regulation for Refrigeration Unit
• The heat bypass for the refrigerator to be
  automated and determined by refrigerator
  temperature
• Water Heating Unit
• Bypass water-heating unit and distiller to be
  added.
• Alternative Fuel
• A conversion kit to be added that will allow the
  engine to run off of compressed natural gas (CNG)
  and gasoline.
• Gas Expansion
• The expanding gas from the natural gas tank to
  be used to aid in cooling the current cool space.

4
Current Status

• Design choices have been made
• All component have been ordered except for the
  natural gas tank.
• 80 of the components have been received.
• Preliminary expansion calculations from Brazilian
  teammates have been completed.
• Design of second cool space.

Collaboration with Brazil Expansion

• The team has accomplished the following via
  weekly video conferences, e-mails and file
  exchange
• Preliminary calculations for cooling effects of
  rapidly expanding gas
• Design of second cool space around distiller
  collection unit.

Conclusion

• Status at End of Fall Design Choices Solidified
• Current Status
• 80 of components in house ready to be assembled
• Change to how expansion will be used
• Scope of Work for Spring
• Assembling and modification to take place in
  January and February
• Testing to begin in March
• Collaboration with Brazil
• Expansion will be used to cool water from
  distiller
