I remember reading in Freakonomics how much more dangerous it is for kids to have a pool in the house than a gun in the house.  I have young kids and so I think about this type of statistic for a while longer than non-parents I guess.

 

Well, this seems like a cool answer to that problem--I am waiting to hear back from this company as it seems they have developed an excellent product called the Hydrofloor.



It is a slow-moving cover for a pool that slowly descends to the bottom of the pool.  It would be the perfect pool cover for an indoor/covered pool, because when it is up, you can walk on the floor.  You can drop the pool to a bunch of different depths, all the way down to the bottom of your pool.

At this point in time, it is probably extremely expensive (I have an email in to the company to see just how ridiculously expensive).  Also they are in Belgium and seem only to be serving Western Europe for now--but once it starts gaining momentum, this type of thing will be all over.
