The idea is great and is essentially the same premise as Beeminder (no relation, just a user)

Instead of pledging an amount up front, you instead provide card details and get charged if you miss your goal.

Once you miss the goal, the pledge multiplies exponentially until you're sufficiently incentivised to do whatever the goal is.

They sound wacky at first but motivation devices are pretty effective, assuming you trust yourself to not game them of course.
