Although over 70 percent of the Earth is covered in water, over 96 percent of that is salty. As anyone who’s gotten a mouthful of ocean water knows, we can’t drink that, and bathing in it is a big no-no. So, we are dependent on the limited fresh water supply, 70 percent of which is used for agriculture. That doesn’t leave much for us, so water conservation has been a hot topic for years, especially in places like Southern California that are suffering from droughts.
Companies all over the world have been coming out with water-efficient faucets and toilets to help, but they have barely made a dent in mitigating the problem, that is, until one Japanese entrepreneur set their mind to the problem. In 2009, a Japanese start-up created a water-saving nozzle that is purported to reduce water usage by up to 95 percent. This could be a life-changing and world-changing invention.
