Rare New Photos Added: Chalk Bicycle Wheel Turbine & Princeton Sailwing Wind Turbine

By Paul Gipe

I’ve added several rare photos and scans Vaughn Nelson found in his files from the 1970s. Nelson, one of the wind industry’s pioneers, has an extensive collection of experimental wind turbines from the period.

I’ve placed these photos under the heading of Small or Household-Size Wind Turbines because that’s where I’ve place other similar turbines. However, they were the commercial size wind turbines of the day.
