This is all good thinking, yet I would not be afraid to work up that 
windmill and maybe some Japanese beetle traps that drop the bugs in the 
water.  I wouldn't get into this as a business w/o a serious look at the 
business and aqua culture angles. Do you weld?  It's pretty easy these days 
with wire feed and lets you whip up tools large and small, braces 
etc.  Lets one nibble away at larger projects and utilize all that junk 
metal lurking around most farms.
