The hot summer has come and the air conditioners are starting to operate at full capacity again. As a heat-resistant tool, air conditioners bring about cool electricity costs and more carbon emissions. If you want to save some electricity and contribute to the environment, we can only shorten the air conditioning time or raise the temperature a bit. Is there any alternative? Yes, an Italian company called Idea3Di developed the Geizeer, a small box with refrigeration. idea3Di claims the box can cool the room in less than a penny. How to do a small box with an ice core and a battery? In fact, its principle is the same as that of ice used in ancient court. Geizeer needs to put its reusable kernel into use Freeze the fridge and put it back into the Geizeer, then turn on its built-in fan to blow air onto the core and finally cool air from the middle outlet. Of course, we can not expect the air-conditioning in the Geizeer kernel to be comparable to that of air conditioners. But if you want to save on electricity bills and over-carbon life, the cooling effect of Geizeer is satisfying enough; if you're really scared of heat, buying a few more Geizeers is a good bet. Geizeer comes with a battery that can be charged using a Micro USB cable just like most of your electronic devices. Benefit from the compact body, the journey can also be used to cool it. The Geizeer project has been a great success on Kickstarter, but you can still go back in time to fund it.
