  36. 36. What  did  we  learn?   •  InnovaCon  to  another  level,  with  ideas  such  as  converCng   mechanical  energy  from  the  push  o  a  door  into  electricity!   However,  in  the  end  we  decided  to  sCck  with  solar  cells,   solar  cooker  and  building  our  own  fridge.   •  We  learned  about  our  energy  needs  in  our  daily  lives  and   how  much  resource  is  spent  in  actually  meeCng  those   needs.   •  We  learned  not  to  give  up  when  things  get  tough  and   believe  in  our  ideas  and  go  on  even  though  its  not   convenConal.

  38. 38. Design  Brief   To  design  a  modular  sanitaCon  system  for  a     retrofit  house  for  two  people  under  the  given     constraints  of  money  and  Cme  (10  days)  that  is     efficient  with  minimum  usage  of  water  and  energy.

  41. 41. Design  Process   For  its  use  as  a  seaCng  toilet,  we   incorporated  three  steps  that  would   raise  the  toilet  seat  to  a  height  of   0.45m  which  is  the  standard  dimension   for  a  human  seaCng  posture  .  also  the   steps  could  be  used  to  access  the   plajorm  if  people  preferred  to  squat.      
  42. 42. Design  Process   we  also  looked  into  methods  of  pouring  saw  dust   over  the  solid  waste  which  would  be  more   efficient  and  hygienic  to  use.  Thus  coming  up   with  a  more  mechanical  soluCon  to  it.

  46. 46. What  did  we  learn?   •  Solid  waste  produces  odour  when  mixed  with   water.   •  Urine  is  a  good  nutrient  because  it  comprises  of   nitrogen  and  phosphate.   •  It  is  more  economical.     •  Eco-­‐  san  is  more  hygienic  because  there  is  no   handling  of  unsaniCzed  waste  faeces.   •  Requires  low  maintainance.

  48. 48. Design  Brief       Design  a  cost  effecCve  comfortable  cooling  prototype   for  4  people  in  hot  and  humid  climate  condiCon  in     10  days  that  resist  calamiCes.         The  design  parameters  were:     1.  Cost:  The  prototype  should  be  constructed  within  the  budget  of  1,80,000  INR.     The  total  esCmate  includes  the  material  and  the  construcCon  cost.   2.  Time:  The  period  of  the  construcCon  was  restricted  to  10days.   3.  Labour:  The  team  for  the  design  and  construcCon  were  unskilled  22  people    from  various  backgrounds.
