Anybody interested in H VAWTs might like to take a look at Eurowind's website
www.eurowind.co.uk. They have made some progress in bringing their small vawt to market, but it seems it will take a while before it will go on sale.
The site has quite a good history of H VAWTs, which was the wind turbine the the UK put its faith and a little bit of research money into in the 1980s. This research ended with a parliamentary committee damming H VAWT research as a waste of money - but when did politians get anything right?
