We begin with watersweeper.com. If you think it’s simply too difficult sweep the dust off your sidewalk with an ordinary broom and pick up trash by hand, you can purchase this sprinkler-on-wheels for only $179. It’s sold as a “quick & easy” way to clean pavement and “blasts away dirt, … litter, [and] pop cans” using a constant flow of pressurized water. Since it only uses 8 gallons of water per minute, “it saves you money”. The idea to waste water on cleaning sidewalk comes to you not from the “Land of 10,000 Lakes” but  from the dry desert state of Utah, where it costs $1.00 to use this device to spray water for 21 hours (10,080 gallons).

At least there’s not a  world water crisis going on, and good thing they didn’t make a documentary film called FLOW discussing the world water crisis.
