> Can you explain how that happens? Why don't we harvest that extra voltage?
You can't "harvest" voltage. The only useful thing you can harvest from an electrical circuit is energy. Energy equals work. Or power, which is just a rate of work.
All the energy you put into an ignition coil and its associated condensor is converted into heat. Most is used (hopefully) by the spark across the plug gap. Some is used to arc across the distributor points. And whatever is left is dissipated by resistance in the primary coil winding and ballast resistor. The voltage spikes seen at the condensor are an indication that energy is being momentarily stored in the condensor, but ultimately that energy is dissipated by resistance in the system.
