I've never heard of a 100% electric TC, as opposed to the regular hydraulic, but you could try using electronic hubs like the 4x4s do. They disengage the axle shafts from the wheel in an effort to boost fuel economy. I think Ford used it for some time on the Explorer. Worth looking into, I suppose, but I don't know it's limitations as to when it can and can't be engaged.

"All I know about music is that not many people ever really hear it. [...] But the man who creates the music is hearing something else, is dealing with the roar rising from the void and imposing order on it as it hits the air. What is evoked in him, then, is of another order, more terrible because it has no words, and triumphant, too, for the same reason. And his triumph, when he triumphs, is ours." -Sonny's Blues
