WindWater / Water boatman

This innovation initially came to life when…

I used dynamometers as an apprentice, to test diesel engines. I wanted wind-powered heating as part of a desalination unit – to make fresh water from the sea.


The purpose of this innovation is to…

WindWater mounted on a barge called Water boatman – uses a thermal still to make fresh water from the sea powered by wind or water currents. The still needs no filters, chemicals or moving parts.

It does this by…

If either of the turbines makes power, the alternator on the shaft, which is also the starter, makes electricity. This heats the brine in the sump. The vapour is condensed in a condenser cooled by the cool brine coming in. The distillate is stored in the hull to await collection. The hypersaline is returned to the sea.


This innovation improves on what came before because…

It uses only renewable power – and the filter will take water however dirty and needs no filters or additional chemicals. The turbine rotor fatigue life is 20 years. The still, with occasional cleaning, also has a life of 20 years.

Its various benefits to the customer/end-user include…

Free water, no replaceable parts or chemicals – apart from annual bearing grease.


In the past, this problem was solved by…

Mains (diesel RO sets etc.) or waiting for the rain.

Its predecessors/competitors include…

Electric or diesel sets.


It is made for…

SA Wineries 19%, SA Wineries waste 4%, Aborigine settlements 4%, remote farmers 4%, export 77%.


It is available for sale through…

Manufacturers representatives.

Our marketing strategy is to…

We will keep the technical press fully informed.
