Backpack power generation for remote sites.

[Frank Gentges]

Tacoistas,

Use of backpack motion whilst hiking can be used to generate electricity 
up to 7 watts while improving the hiker's walking stance and reducing 
the hiker's effort.

This suggests a number of applications using amateur radio, APRS etc.
