Hybrid Generators

Technology Review has this piece on hybrid generators for the Marines. Instead of sizing a diesel generator to meet peak power demand, the idea is to use batteries capable of meeting the peak demand, recharging them by running a smaller generator when they're drawn down. My Army career ended by running 45KW diesels supporting telecommunications trailers. As I remember it, we ran them at roughly 30KW much of the time, though it varied. The new concept sounds good, though the equipment is significantly more complex, both the batteries and the charging and control software.  That may be a problem: though I was obviously a great operator, the Army didn't expect us to do much. We could start them, shut them down and change the oil and not much more.
