just a few comments that came a couple hours after reading mostly a comment on military largescale systems. only time will tell. well either time or a cadre of dod funded researchers and engineers. it's still quite smallscale however considering the US DOD especiallies new robotic /unmanned units.. all they need is fuel sustainability and you have a continously (except repairs etc..) mobile unit... just add a a variety of choice ai systems.. whala. a new techno monster drone which could be programable for a number of tasks.. and yes they have programmed hunterseaker flying drones befor so I have heard. its gets sicker when you consider their stealth systems.. including chameleon system.. but it seems that the microbial fuel cell is being geared towards small scale recon and sensor units. the other though although I'm not a bibleprophecy person is could the future flying locusts be the black flying things that plauge the faithful.. or in modern times those that do not display their VISA? you know the story.
