Fifteen Years ago, Kevin Costner was drinking his own pee.  Filtered pee, of course, for his epic 1995 film “Water World“, which is best know for being an epic flop.

But wait!  Could there be some benefit from this bleak look into a future without dryland?

It seems that when Kevin was in the aqua-survivalist mood he invested in a developing a pump technology which separates oil from water.  Costner, an adamant environmentalist, may have only wanted to clean up the water from the myriad of gasoline explosions that took place on the open water set when he gave $20 million to his scientist brother.

Just another example of how the movies are advancing the human race!
