If you take a look around the GE or Siemens web sites, you'll see another
interesting application options for those huge mining trucks---an
all-electric 
operation mode. By adding overhead power delivery wires to the mining
site 
and trolley poles to the trucks, they can run in all-electric mode for
more 
power, faster speeds, and greater load handling capability. Not to
mention 
reduced pollution and lower diesel fuel usage. Off the wires, they resume
diesel-hybrid operation. No kidding!
