  • Submitted a Stage 2 funding 
  • Working with Raphael Saturday
  • Getting ISEC user feedback 
  • Comments on design 
  • Big handles will make pot lose heat
  • Bucket is long, thin, tapered
  • Not a lot of room for insulation better off getting a wide bucket that is shorter
  • If you are going to use long, skinny bucket move the pot up in the bucket, pot sits in bucket and fill in empty bottom space with wool 
  • Insulate the top

Salma

  • https://www.youtube.com/watch?v=Y_5qlXdULQY
  • Hawazin: How about using a smaller pot and place the metal chunk between pot and heater? 
  • 1L (2.7kg) aluminum puck, provides 2 hrs of thermal storage 
  • ideally want 2x the mass 
  • Aluminum puck needs a "flat bottom pan" 
  • Simon: flat bottom pans are hard to find in Africa 
  • experimenting with chainmail glove
  • 1 cm thick disk welding it to pot 
  • Crosby: have 2 separate pots, one pot unit with thermal storage and one without 
  • Suggestion: supplying two kinds of finished product, give them choices, thermal storage would be seen as an extra 
  • Nutritionally there's value to keeping something in a 60-90 degree range
