HZO For H20
"When given a choice to buy a regular compass or one that's waterproof for $50 more, people choose the waterproof one nine times out of ten," said Chris Weed, director of business development at HZO. The flagship of this 2011 nanotechnology startup is WaterBlock, a dielectric thin-film coating that makes electronics impervious to water and other liquids while adding very little to device cost. "The cheapest way is to apply our coating during the manufacturing process, which adds about $10 to the end-user price," he said. If added afterward, Weed said WaterBlock might add around $60 to the cost, a steal compared with an inundated iPhone.
