Fuelled by Coffee

Running   a   diesel   engine   on   a   plant-‐based   fuel   is   hardly   a   new   idea.   One   of   the demonstrations _______  (38)  out  recently  in  the  University  of  Nevada  revealed  that it was easier to produce diesel fuel from crude oil.  As biodiesels  are  becoming _______ (39)  throughout  the  world, a great   number   of   scientists   and   environmentalists,   together   with   several   international organizations such  as  IGN  and  NCF,  seem  ______  (40)  various  sources  in order to  find  sound solutions to  the world’s energy  problem.  In   the   case   of   coffee,   the   biodiesel is made from   the   leftover grounds, which   are usually   thrown away or used as   compost.  ______ (41)   in   almost   any   sort   of   engine,   biodiesel fuel does  not  have  an  offensive  smell  –  just  a  whiff  of  coffee. What  sounds  attractive  about  this  ‘coffee -fuel’  is  that  the  coffee  grounds  can  still  be  used  of  compost  after  the  diesel  fuel  has  been  extracted. Susanta  Mohapatra’s   57-‐page   report, _______  (42)   the   idea   of   ‘coffee   fuel’   is   based,   is expected  to  provide  a  great  deal  of  valuable  information _______ (43)  the  features  of  this  new  type  of biodiesel   fuel. Unlike biodiesels   found   in   the market,   coffee biodiesel does not ______ (44) cultivable lands into fuel stations. Another  advantage  is  that  unmodified  oils  from  plants  like  the  peanut  oil have high  viscosity  _______ (45)  coffee  biodiesel  is  far  less  thick.
