What is the Open Source $30 Wind Turbine project?

This project details the construction of a low-cost, open-source Vertical Axis Wind Turbine (VAWT) using the Lenz2 lift+drag design. It is designed to be built predominantly from scrap materials, costing between $15-$30.

Who would benefit from building this open-source wind turbine?

This wind turbine is ideal for individuals or communities seeking an affordable, DIY solution for generating electricity or powering pumps. It targets those with access to basic tools and an interest in sustainable, low-tech energy solutions using recycled materials.

How does this wind turbine differ from other DIY wind turbine projects?

Its primary differentiators are its extremely low cost ($15-$30), reliance on readily available scrap materials like aluminium printing plates and bike wheels, and its specific use of the mechanically efficient Lenz2 lift+drag VAWT design. It also provides detailed, animated instructions.

In what scenarios is this open-source wind turbine most suitable?

It is suitable for applications requiring decentralized power generation, such as off-grid systems, irrigation, or cooling, particularly in areas where resources are limited and low-cost, durable solutions are preferred. It functions effectively in varying wind conditions due to its VAWT design.

What kind of power output can be expected from this wind turbine?

A six-vane version with a 0.91m diameter and 1.1m height, coupled with a 90% efficient alternator, is calculated to produce at least 130 watts in a 30 km/h wind and 1 kilowatt in a 60 km/h wind. The design has been survival tested up to 105 km/h sustained winds.
