With some 1 billion people on the planet without access to safe drinking water (NOT a typo), the invention of a device called the LifeStraw could have a profound impact on world health. The LifeStraw is a plastic tube with no moving parts. The user simply drinks from any water source and filters in the tube actively filter out and kill bacteria such as typhoid, cholera, e. coli, salmonella and other common killers. The straws will cost around US$2 and can process 700 liters (around one year’s worth) of drinking water.
