Need ways to start a car with a dead battery.- 92 Civic Auto.

I have been thinking of a good way to prevent stranding
myself from a dead battery. It happened twice. Once at a
beach from leaving my lights on. The other was at a college
campus which the stereo and the dome light ran down the
battery. Unlike the beach, the college campus have lots of
helpful students with beat up cars that have jumper cables.
Now, I have a new idea. Once my battery runs dry, I
remove my alternator belt and wrap a rope around the
alternator pulley. I then pull the rope so it'll turn 10
revolutions per pull. I keep doing this for about 20 times.

What is the possibility that this will supply enough charge
to start the car. If not, can somebody think of a clever idea
to start an automatic?

Thanks
