you have to add to the losses of the turbine, the losses of the battery required, (the rest , electronics can be efficient) that may be 50% from in to out later
maybe supercapacitor/nonsupercapacitor can help, or freewheel? 2014-10-13 2:08 GMT+02:00 Robert Lynn <[email protected]>: > no small rankine turbines or steam engines are that efficient.
