Using an AMR500 Roots type supercharger ($100 cheapo) which is meant for up to 1800cc gas engines... to light my chimney style charcoal starter. I haven't mounted it yet but for now I spun it with a drill @ 4000rpm, it's max speed is 20,000rpm, and they say 16,000 is the max continuous RPM so lots more power potential. I got this for a series of experiments I am conducting. If you'd like to see more then stay tuned, comments and questions always appreciated.
