Recycled Plastic Barrels Create Cheap Wind Power For Developing Countries


Enquiries from developing countries for cheap renewable power prompted Luethi Enterprises to create an efficient, cost-effective wind turbine that can be easily manufactured from plastic barrels.


These 220 litre barrels (55 gallon drums) are used for transporting a wide range of fluid materials and are easy to obtain.


Existing VAWTs made from such barrels are inefficient, and require very high winds to function.


The blades of this new design are cut in a unique way that creates lift. This wind turbine requires very little breeze in order to achieve its 250W output.

The design for this 250W VAWT is registered, and the patent is pending.

Like all our turbines, the 250W barrel turbine doesn't need any external power sources.

It's also ideal for heating water, security lighting, street lighting and emergency lighting.


The design of this 250W barrel turbine has been registered - it's ideal for use in developing countries as a cost-effective, independent power source.


Here's a short video clip of the 250W barrel turbine in action. (9 seconds; 1.85MB; WMV format.)


This was filmed in approximately 6 knots of wind.


As this design uses recycled plastic barrels, it's extremely environmentally friendly.


Performance data is not yet available for this model. Please note that this does NOT use the unique, patented mechanical speed regulator in order to keep costs down and provide affordable renewable energy for developing countries.


This turbine is silent, but if you are looking for a turbine with speed regulation, please refer to the 500W DC Silent Wind Turbine.

Totally silent
5 year guarantee - provided we supply the plastic barrel
Ideal for remote applications
100% of power available to the end user
Easy to install and maintain
