the late 90s/early 2000s my interest was in developing boats that can sail
directly into the wind.
To some, this seems impossible, and they find it hard to accept that it is possible to
overcome the wind
using the force of the wind itself. (click here)
for some objections raised on various newsgroups.
This technology has further implications also, it can allow a boat, or a
buoy, to remain stationary in the water, unsecured, no matter how hard the
wind blows without using any fuel.
Using this system, anything on the water cannot
be "blown" anywhere (for example
into a "lee" shore).
It works 24 hours a day with zero fuel used and zero
In the light of the recent concerns about climate change and in
the situation that shipping contributes more carbon to the atmosphere than aircraft, there
should be some role for a windpower system that allows sailing on all points of the compass.
Due to the concern now about climate change. The Rotary Sailing system is
very suitable as a wind-assist system for both small and large ships. It
offers the ability to gain windpower from headwinds, which is a feature
which other systems - for example wingsails, Flettner rotors and
Ventifoils do not have.
