Ronald Nelson, founder and owner of Next Step Family of Products LLC, suggests a concept for redevelopment of Burke International Airport in Cleveland that could replace the cultural and tourism value of the air show with a permanent cultural, ecological, and educational lakefront district inspired by the World's Fair and other projects like the Eden Project. The concept could create a $76.6 million annual economic footprint, with large glass biomes themed around Great Lakes ecology, global climate zones, sustainability and green‑tech innovation and indigenous ecological knowledge. The proposed development could exceed the city's optimistic $92 million annual projection and generate an annual economic impact of up to $200 million. However, it would require major investment, potentially transformative.
