Walk on Water Challenge


Backyard pools are awesome, except for those 4 - 6 months when it’s too cold to swim. Then the pool becomes an obstacle to using the backyard at all. I want to bring kids and families back outside by designing a durable pool cover that is safe enough to walk on (and skip on, jump on, wrestle on, dance on, . . . .)  This solution repurposes the concept of the entire backyard, not just the pool space alone.  A durable pool cover opens up the patio around the pool so that the entire combined areas (pool and hardscaping) can be covered with high quality cushioned artificial turf.  Presto chango! The entire area then becomes a space for play and entertaining.  A crew of 2-4 workers will be able to install and uninstall this pool cover in a single afternoon.

Hi Everyone, 


We have had an amazing response to the Walk on Water challenge so far.  We've also had nearly 5,000 people show interest in this project and about 130 innovators indicate they're going to submit a proposal.


Thanks to everyone who has already submitted their proposed solution to this challenge. We've had some really creative ideas influenced from all walks of life.  I'm already buying materials to run some tests on some of them.


My fellow judges and I are eager to see all the submissions.   Remember the deadline is around the corner on June 21, 2019. 


Thank you.
