The Tech Museum Awards recognize projects that make the world a better place. The Museum, located in San Jose, California, recently named 25 winners. They come from all over the world, including Nigeria, Japan, India, England, Brazil and the U.S.

At a ceremony in November, Microsoft Chairman Bill Gates will receive the museum's Global Humanitarian Award for the work his foundation has done in health and education.

This year's winners include an effort to squeeze drinking water from fog; a refrigerator for an African desert that gets its power from evaporation; a project to archive all of the Internet; and a plan to monitor and map mosquitoes to cut down on Dengue fever.
