What is one of the things astronauts really miss when they’re out in space? A more exquisite dining experience. Scientists have developed a space fridge design that might put an end to beef jerky and canned foods in astronauts’ diets. It would also keep food supplies edible for a considerably longer time.

A team of engineers at Indiana’s Purdue University have created an “ultra-white” paint that is capable of reflecting up to 98.1% of sunlight, that could potentially negate the need for air conditioning and even reduce carbon emissions if used on a mass scale.
Developed as part of a six-year project, the researchers say that if the paint covered a 93sqm roof area it would be able to create a cooling power to ten kilowatts, far more powerful than domestic air conditioners.
The paint is made with a chemical compound called barium sulfate, that is used within cosmetics and photo paper to make them white. The barium sulfate particles are made up of different sizes which scatter sunrays and are able to cool immediate surrounding surfaces. The size of the particle determines how much light it scatters, so a wider range of particle sizes allows the paint to scatter more of the light spectrum from the sun.
