weather balloon? [RE-wrenches]

[Ian Woofenden, Home Power]

<x-flowed>


We've found 3-foot diameter balloons (and helium) at party stores. 
With two pieces of fish line (one vertical and one to the windward 
side), you can get these balloons up to turbine height. Streamers 
every 10 feet will show you where the turbulence drops off, and the 
ballon will show you where the turbine will be seen from.
