There&#x27;s an old paper by Salter on the possibility of doing this through hydraulic pressure, having the turbine drive a pump, the weight being a piston within the turbine tower, and the output of the system being a hydraulic generator. This was back before modern developments in inverters meant that turbines had to have either a gearbox or a hydraulic torque conversion system like a car&#x27;s automatic gearbox.<p><a href="http:&#x2F;&#x2F;www.artemisip.com&#x2F;wp-content&#x2F;uploads&#x2F;2016&#x2F;03&#x2F;1984-Salter-Hydraulics-for-Wind-3_0.pdf" rel="nofollow">http:&#x2F;&#x2F;www.artemisip.com&#x2F;wp-content&#x2F;uploads&#x2F;2016&#x2F;03&#x2F;1984-Sal...</a> (SH Salter, M Rea, proceedings of European Wind Energy conference 1984)
