1 Lessons From 30+ Years of Experience No Panaceas No Cheap Solutions No Breakthroughs--No Miracles Numbers Matter Experience Matters Size Matters Paul Gipe, wind-works.org

2 Lessons Always Check the Numbers Vortec: The Numbers Didn’t Add Up Always Check the References Vortec: References Discredited in the USA Always Google Vortec: Ducted Turbine Critics on the Web Always Go to the Library... Or to Your Neighborhood Bookstore! Lots of Wind Books Now Available Paul Gipe, wind-works.org

3 Lessons Always Be Wary of “New” Designs © Vortec Paul Gipe, wind-works.org

4 Scams, Frauds, & Flakes Tell-Tale Signs Hype High--Experience Low New Design-- “Not Like Those Others” “New” Patents “Works @ 2 m/s! Drag Devices (Squirrels in a Cage) Ducted Turbines! Pyramid Schemes “Get in on the Ground Floor Now” Fancy Web Sites Cheaper than Hardware Paul Gipe, wind-works.org
