It's a Nano Hummingbird!
Aerovironment has been working on this since 2006. Under a $4 million contract from Darpa they have a hummingbird drone that weighs 19 grams, flies 11 mph, can hover, fly forwards, backwards or sideways, turn clockwise and counterclockwise and flight time is 8 minutes.
19 grams! Battery, motors, communications, video camera, and hummingbird paint scheme. That's less than 4 nickels in weight.
The pentagon mileposts for this project include hovering in a 5 mph wind, fly indoors and back out through a normal size doorway.

An urban spy? 'cause nobody is going to notice a hummingbird in a city? They'll either take photos of it, try and catch it or shoot it. They should have made a spy pidgeon, even better a rat. Easier to do and wouldn't be noticed.
Did they really think this through before spending our tax dollars?
Saw this report on this project here as well today -
U.S. military’s newest urban spy
hmm a humingbird drone looks pretty good but 8 minutes of flight time is a little low
need that revolutionary battery tech maybe those solar cells or stick a wind turbine to it
@Paul Marsh
I need one of those
then all it needs is kevlar and some stinger missles then we can sell them to the goverment for millions haha
Quoting my source http://en.wikipedia.org/wiki/Lithium_air_battery
The theoretical specific energy (of a LiO2 battery) excluding oxygen is 11140 Wh/kg, or 40.1 megajoules per kilogram. Compare this to the figure of 44 megajoules per kilogram for gasoline (see petrol energy content)
And paraphrasing from Hollywood we may not need no stinking engines
