Vertical Axis Wind Turbine: An innovative commercial mid-scale VAWT.


HAWT = horizontal wind turbine: infrastructure-scale off-shore ‘monsters’ now delivering an appreciable proportion of already commissioned renewable energy technology around the world.

VAWT = vertical axis wind turbine: centuries old technology overlooked in the race to develop commercial scale viability from wind resources. Very effective in on-shore, urban environments with turbulent wind resources.)


We cannot trust politicians and vested business interests to decide our planet’s future. Climate change is threatening to bequeath our grandchildren a polluted climate and a diminished bio-sphere unless more people take action and get involved Consider this: what if you could make your own electricity from renewable energy sources? That would be a game changing concept, because not only will you guarantee your own supply at little or no cost, but you will also hedge against price increases by 3rd party suppliers and reduce your dependence on fossil fuels. All of which is good. And you can access the technology to do this right now.


Wind turbines are set to become the most efficient, widespread and cost effective renewable energy technology, but the off-shore infrastructure-scale global fleet of horizontal axis wind turbines are inaccessible and costly to install and to operate. 4Navitas have been prescient in anticipating a future market opportunity, and after 5 years and £5M investment, they have developed a hyper-efficient yet beautifully simple version of this well-known technology. They have succeeded where many have failed, by developing  a number of patent protected design features that enable their turbines to convert wind driven circular motion into exceptional amounts of electricity that can even exceed the Betz limit.

This wind turbine is unique because it is simple and relatively inexpensive to manufacture, transport, install and operate and it will never be subject to future carbon taxes. It has been over-engineered to ensure whole of life performance efficiencies and operating safety, and can be dismantled and re-erected in new locations if required. 


This short video takes you behind the scenes to find out how they are made and installed:


4Navitas recruited Siemens as a major component contributor to the project, by providing a fully integrated drive system. Richard Fear is business development manager for Siemens IDS systems: “Working with 4Navitas on this innovative micro-generation project has been an excellent application of our IDS principles, helping develop a highly-efficient turbine with good power output. The long-term projections for this VAWT turbine are significant, both in terms of applications and enhanced asset life.“


 And for their efforts, 4Navitas’ received green industry recognition recently (Feb 2017) when presented with a prestigious international award at this year’s Green Global annual award party held in Los Angeles.

We are now engaged in a major marketing push to build a global network of Regional Partners with the resources to make and distribute (sell and install) these turbines. 


Regional partners will need local customers, and that’s where you can help.

We are currently setting up Regional Partner joint ventures in the USA, West Africa, East Africa, Middle East, Central Europe, Malta, Turkey and Siberia. 4Navitas business headquarters are in NW England, but their market is global, and they will need a global network to help get this technology out there. 


This GCV/4N project is 4N’s first Joint-Venture to set up a sales and technical support hub in Prague, able to develop and support Regional Partners and their customers world wide.


We invite you to get involved and help us make more people aware that this technology is available, accessible and affordable. There are communities around the world in desperate need of this product. We want to by-pass existing vested interests and distribution channels by establishing our own network of informed activists passionate about the environment, caring of humanity and wanting to do something that will make a difference, and be rewarded for their contributions. 


Here are a few examples of the uses for these turbines:


Agriculture                                                  Developing nations

Urban environments                                   Business and commercial centres

Residential developments                           Isolated communities

Micro-grid applications                              Humanitarian support

Inhabited islands                                         Community projects

Military bases                                             Wind farm/park developments
