At home there's an outlet only about 1 m from the hood, so that's perfect. A block heater is probably the way I'll go. I get green power.
I just like the elegance of a thermos solution, and the facts that (a) it's on-demand; no need to predict when I'll be leaving and (b) it works when I drive home from work (no outlet).

One thing I actually considered and haven't dismissed the thought yet is to use the warm water drained from my morning shower -- comes at just the right time. Just need to figure out a way to pump it around the engine...

Heating the entire block etc. is best but requires lots of energy, but maybe as a compromise one could start by heating only the intake manifold; I'll start a thread on that.
