  16. 16. Feasibility <ul><li>Economics </li></ul><ul><ul><li>Less than $1000 (less than 2x the cost of a standard grenade) </li></ul></ul><ul><ul><li>Most parts are off the shelf and offered by multiple vendors, with the possible exception of the casing </li></ul></ul><ul><ul><li>Marketability: Military and police usage, data collection </li></ul></ul><ul><ul><li>Possible applications in scientific mapping and observation. </li></ul></ul>
  17. 17.
