<br><font size=2 face="sans-serif">The National Science Foundation gave
a few grants for researching this type of idea, apparently they thought
it could deliver payloads (like spare ammunition, parts etc.) to certain
areas.</font>

probably can tell you more, they are having their convention in Topeka,
KS tomorrow, watch for some of their balloons tomorrow on APRS.</font>

<br><font size=2><tt>It would sure be fun to design smart packages...<br>
<br>
When dropped from a balloon, each one would glide itself to its<br>
assigned GPS delivery address. A GPS, a uP, some tiny<br>
actuators, and I would think you could put this into something<br>
the size of a toilet paper tube. With short stubby wings.<br>
<br>
A great student project...<br>
Of course, APRS would track the success of these...<br>
So much fun, so little time.<br>
They would have to be lightweight and "bounceable" so that they<br>
bounce right off of windshields and leave no mark on someones<br>
hood...<br>
<br>
But Gravity is a pretty reliable propulsion system...<br>
