Product Inspiration

Hydrophobic products like Rain-X “repel” water, usually by preventing the droplet’s surface tension from being ruptured. In the last year or two, there’s been a bunch of improvements to this science, ranging from nano-etching small bumps in glass (the gaps between the bumps are too small for water to fit), to super-hydrophobic coatings like this.

With something like this that repels water so effectively, there are opportunities to improve everything from outdoor equipment to precision lubricated surfaces. Best of all, this powder appears to be very cheap to manufacture, so perhaps we’ll see some new waterproof gadgets in the not-so-distant future.
