Introducing the BOB System – A Low-Tech Shading Innovation from Wheaton Labs
The BOB System is a passive cooling solution developed at Wheaton Labs as part of the Permaculture Technology Jamboree. Led by Stephen B. Thomas, the PermacultureBootcamp Leader, this project was designed to create dynamic shading using a tensioned cable system, weighted logs, and pulley mechanisms—all without the need for electricity.
Unlike conventional shading methods, the BOB System integrates natural movement compensation, using a tree-mounted pulley system to counteract sway while maintaining consistent cable tension. It serves as the foundation for a multi-layer shade system, with additional support lines allowing for expansion and increased cooling efficiency. The result is an adaptable, durable structure capable of reducing heat exposure in workspaces, gardens, or any outdoor environment where cooling is essential.
For those interested in building their own BOB System, we’ve created a detailed 50-page PDF guide featuring:
✅ 3D renders and illustrations for clarity
✅ Step-by-step instructions covering cable tensioning, anchor points, and weighted log mechanics
✅ Technical breakdowns of the pulley system, deadman anchors, and structural reinforcements
✅ Insights from hands-on testing at Wheaton Labs, where multiple iterations refined the system for maximum effectiveness
This is more than just a shade solution—it’s a permaculture-based approach to engineering that blends functionality, simplicity, and resilience. Whether you’re looking to cool an outdoor space or experiment with low-tech, high-impact designs, the BOB System plans will give you the tools to build it yourself.

The core concept of BOB is its bobbing motion—designed to move up and down as the tree sways, while keeping the line consistently taut.
The plans are done! We've gone through it so many times that we're a bit numb to it now. If you catch any wonky bits or have feedback, we’d really appreciate it if you let us know. And here’s a sweet deal—if we implement your feedback, you’ll earn yourself some tasty pie as a thank-you!
