DuoGen was recently one of several wind generators tested by Tim Bartlett for
'Sailing Today' magazine. This was a comparative test, using the facilities
at one of Oxford University's wind tunnels.
The results will be published and discussed in the August issue of 'Sailing
Today'.
It was, of course, only part of DuoGen that was assessed, as the water mode
performance, quick change of mode and easy storage etc. was not included.
The fact is that DuoGen is such a unique product that the alternatives can only
partially compare.
| DuoGen is included in the "Gear: New Products" section of 'Sailing
Today', in their July issue. Also, we're expecting our video to feature
on the PBO web site any day now. Look out for these and other mentions in the media! |
DuoGen is the only wind turbine designed for yachts to be protected by self-furling.
In high wind speeds, the blades of conventional wind turbines progressively stall in order to keep rotational speeds and electrical output within reasonable levels. However, the machines themselves continue to face the wind and, as the wind increases, so does the loading on the rotor's disc, producing very large forces which are transmitted through the turbine's mountings to the yacht and her moorings.
DuoGen is designed to furl, reducing the intercept area of the turbine disc in response to gusts and sustained high wind speeds, thereby minimising stresses to the mountings and the yacht whilst maintaining an impressive output.
By far the majority of queries we get from potential customers are about fitting.
With such a range of sizes and styles of yacht, it's not surprising that people
have difficulty in working out how DuoGen can be mounted on their yacht. Well,
we are now producing a mounting 'cradle', which holds the two mounting points
on DuoGen, and then fixes to the rails.This gives even greater flexibility of
mounting positions, and should solve most of the problems encountered.

We've had several enquiries from owners of this type of sailing cruiser, and
we have to say that DuoGen is the perfect renewable energy system for them.
Usually on this type of vessel wind turbines have to be mounted on the forward
face of the mizzenmast because pole mounting at the stern interferes with the
mizzen boom and sheets when sailing. This requires bespoke bracketry and the
need to drill holes in the mast.
DuoGen allows a stern mount because the water mode is deployed when sailing
and is therefore out of the way.
Look out for pictures from some of our installations.
They may help you to visualise how DuoGen would look on your yacht.
And check back often as the pictures will appear as soon as we have them!
