Shrinking jug keeps milk fresh for an extra week

Milk goes sour in about a week, even if you keep it in the fridge. That's because Lactobacillus, the "good bacteria" that's found in yogurt, is constantly going about the job of oxidizing the lactose sugars in the milk into sour-tasting lactic acid - the same chemical that makes your muscles sore after exercise. But since this souring process requires the presence of oxygen, theoretically it could be slowed down even further if you kept the milk out of contact with oxygen. Rather than going with a high-tech nitrous contraption like the N2Wine globes we wrote about recently, one entrant to this year's James Dyson awards has come up with something devilishly simple: a shrinking milk jug that squeezes all the air out as you empty it. The inventor claims it lets milk last as much as a week longer. Simple and brilliant! Read More

A fridge that positively thrives in direct sunlight might seem a bit of a strange idea, but if you find yourself in a baking hot country where keeping your medical supplies cool and fresh could mean the difference between life and death, or you just want to sell some chilled refreshments to passers-by, then you need a portable, stand-alone chill solution. Industrial Insulation Systems (IIS) has developed a solar powered fridge/freezer which can be tailored to meet the needs of these off-the-grid scenarios. Read More

There’s no doubt the refrigerator is the central hub of the kitchen, serving more than its primary purpose of keeping things cold. In recent years we’ve seen fridge manufacturers pack their products with all manner of technological additions, from iPod docks to touch screens and TVs. In most households though, the humble fridge remains a central place to stick notes that are sure to be seen. Whirlpool has saved us the hassle of hunting for a scrap of paper on which to scribble such missives with the Amana Jot refrigerator. Read More

Solar powered devices aren’t new, but English student Emily Cummins has developed a way of using the sun’s power to help impoverished communities in Africa. Her eco-friendly, sustainable fridge is based on a simple principle: it uses the sun’s rays to evaporate water, which in turn keeps the contents cool. Read More
