Hydraulics vs Mechanics on Wind Turbines

Hydraulics vs Mechanics on Wind Turbines

Hydraulics vs Mechanics on Wind Turbines

(OP)
Is it possible to use a pump as a more efficient means of transfering the energy from the turbine to an alternatore ground on the ground.  Easier to maintain, regulate PSI?  Am I crazy or does it make sense?

RE: Hydraulics vs Mechanics on Wind Turbines

It does not make any engineering sense for short distance transfer - if you refer to transfering a fluid via a pump run by the turbine to a hydraulic motor on the other end where to convert back into mechanical energy -> generator.
 Firstly, your system efficiency will not beat the efficiency of a mechanical transmission - therefore you are losing power.
 Secondly, you will use a pump and a hydraulic motor plus various instrumentation - cost to install and to maintain this solution will be prohibitive for a short linear transfer.
 It will start to make economical sense as the distance of the transfer increases - and it is used in these cases.
 Hope this help.
