Revolutionary growth companies...

Revolutionary growth companies can come from anywhere and do just about anything. Witness Falcon WaterFree Technologies, a private company that may change the way we go to the bathroom -- and save the world in the process.

About WaterFree
Falcon WaterFree Technologies makes urinals that don't have to be flushed with fresh water. According to the company, each urinal saves approximately 40,000 gallons of water per year and is far less expensive to operate than a conventional urinal.

In a world where fresh water is a finite resource and our global population is growing larger by the day, you can see why Falcon may just be the next big thing in toilets.

Even better for the business, the urinals function with a filter that periodically needs to be replaced. That's exactly the razor-and-blade economic model that's so lucrative for razor makers such as Procter & Gamble (NYSE: PG) and for printer-print cartridge makers such as Dell (Nasdaq: DELL) and Hewlett-Packard (NYSE: HPQ).
