Why do it the hard way?
Good idea, but wrong direction. Use a REVERSIBLE drill and run the speedo backwards for 4K rather than forwards for 96K! Using the calcs from the kwh post, this would get your run time down to a little over a day, saving lotsa' electricity and tipping the cost-benefit analysis back in favor of the re-set.
