&gt; &gt; you use a rheostat, you lose the energy as heat, and the batteries

&gt; I wonder how diesel locomotives do it.  Their engines drive 
&gt; generators; electric motors drive the wheels.  Massive 
&gt; transmissions and drive shafts are less efficient and harder 
&gt; to maintain, I guess.
&gt; 
&gt; IIRC, an electric motor's torque varies with current, and its 
&gt; speed varies with voltage.  So, what about using a 
&gt; transformer tapped for various voltages?  It'd be like an 
&gt; electric transmission.
