Pretty cool if you ask me... :)
But how much fuel are you going to use waiting for the engine to warm-up?
From Car Talk:
RAY: But with modern cars, all you're doing with a long warm-up is
wasting gas, increasing pollution, raising the temperature of the
planet and making yourself 10 minutes late for your chiropractic
appointment. The proper procedure is to start the car. If it starts
and keeps running, put it in Drive and go. Go gently (don't back out
of your driveway and floor it right onto a highway entrance ramp),
because you'll be warming it up during your first few minutes of
driving, but DO drive it.
TOM: If it's bitterly cold out, like 10 or 20 degrees Fahrenheit or
lower, you can let it warm up for a minute or two to allow the oil to
thin out a bit and circulate completely. But other than that, if it
runs, driving it gently is the best way to warm it up.
