A wind turbine unit for generating electricity in a confined space includes a pair of sails carried at either end of a pair of spaced, axially aligned rotatable arms mounted to the drive shaft of an electrical generator. The system according to the invention includes a remote control having a microphone for the input speech commands. The software models are preferably stored in a model repository which is searchable to enable a user to select the instrument function or traditional mode of operation to be simulated with the corresponding model being provided to the electronic components. A mounting block is symmetrically supported by the plurality of load sensors and a current measurement device measures a sum of currents output from the plurality of load sensors.
