Hi Peter, I just ran across this.. http://www.qualcommtricorderxprize.org/ Although your project isn't for medical purposes, this still looked interesting. Looks like there's a lot of XPrizes in this area though... http://nokiasensingxchallenge.org/ Even an ocean health XPrize... http://oceanhealth.xprize.org/

  Are you sure? yes | no
