An auto mechanic in Argentina had a dream about extracting a cork from a wine bottle, which -- bizarrely but wonderfully -- led him to build a device that could potentially save the lives of babies stuck in the birth canal and greatly reduce the number of cesarian surgeries performed each year.

As the New York Times notes, Jorge Odón built the prototype for his dream device using a glass jar, his daughter's toy doll and a fabric bag sewn by his wife. And now the World Health Organization is one of its major supporters, and the device (which is being modified from its barebones prototype, naturally) is licensed for production.

All of which is to say that Odón is perhaps the most impressive dreamer alive today.
