Risk assessment

Scouted for peltier module

  1. Visited 2 companies to check out commercial peltier modules
  2. Visited MnT lab to check out their peltier modules and past projects using peltier modules, and learn what accessories are necessary for using them

Designed cap for attaching peltier module and power source to ice block

  1. Decided to not use peltier modules as the cooling unit and power source necessary to operate peltier module are too bulky and heavy

More basic trials in MnT lab

  1. Froze a large ice block using a fridge in CBC store which can go down to -70°C
  2. Slid ice frozen in CBC store on a 2.5m track found in the MnT lab

    Fig 2.1: Sliding grooved ice along blunt 2.5 m tracks

  3. Slid dry ice on chemically inert and smooth lab table

  4. Experimented freezing ice using a block of dry ice
