Low speed windmill

Wind power for the ordinary householder.

'Windsave has developed a unique slow turn generator which provides supplementary electricity from wind power at very low wind speeds starting at 5mph.

It can be fitted to most buildings either as a single unit (e.g. houses) or as a multiple framework of units (e.g. for commercial premises)...

by providing supplementary electricity into your mains the Plug 'n' Save system reduces the amount of electricity that you need to buy from your utility.'

Sold from Glasgow, UK
