I am not promoting Tesla Motors here, just the clean energy concept.

This is where you and I disagree. Take a look at ocean freighters and how they capture every once of energy from burning diesel. There are multitude of capturing and converting waste energy.

If your theory is indeed true, why we wouldn't all of us have generators at home? We would not have to deal with transmission losses which is something you brought up.

Electrical power distribution appeals due to economy of scale and converteribility.

Diesels are the most efficient type of combustion engine and low RPM diesels, like marine diesels are the most efficient type. Even so, the thermal efficiency of the very best of these is only slightly greater than 50%.

With coal and fuel oil having ~40% energy conversion efficiency for power generation, the excess energy is going somewhere other than friction losses. For the most part, it's going up the stack or in the coolant water outflow. In fact, if your efficiency is too high, you won't get proper flow out of the stack (i.e., hot air rises).
