Here’s a possibly world changing idea- a refrigerator that doesn’t need any electricity. Tech venture capitalist Adam Grosser and a team of Stanford thermodynamics experts came up with a fridge that works almost in reverse. There’s a refrigerant pack that is activated when heated up. Once activated, it’s like a supercharged cold pack that will keep items cool for up to 24 hours before needing to be charged up again. The pack costs $50 and can be used to keep almost anything cool, from a jug to a bag of vaccines to items covered up in a hole in the ground. The possibilities are great.
