The morning coffee is a ritualbeloved by hundreds of millions of people around the world.

Now a team of inventors has improved this daily pleasure with metal beans that can keep your drink warm for up to five hours.
The beans, called Coffee Joulies, cool down your beverage to a drinkable temperature three times faster than normal, and then maintain that temperature.
They work by absorbing extra thermal energy in the drink when it's too hot, and then releasing that stored energy back into the drink to keep it at an optimum temperature as it begins to cool down.
For the stainless steel shell and the mysterious material in the Coffee Joulies, some people hold the opinion that it may do harm to our health. In fact, Coffee Joulies contain a "special non-toxic material" sealed within the beans.




对于很多人来说，每天早晨起床喝一杯咖啡已经成了生活必不可少的一部分。
最近一些研究人士发现，用一种"金属咖啡豆"可延长咖啡的保温时间，最长能达到5个小时的保温效果，这项研究大大提高了喝咖啡的乐趣。
这种咖啡豆，也叫作茹利咖啡豆(Coffee Joulies)，可以三倍于往常的速度将咖啡降至适宜饮用的温度，并保持恒温长久不变。

保温咖啡豆的原理其实很简单，当咖啡很烫时，它会吸收多余的热量，待到咖啡开始变凉时，这些豆子又会释放吸收储存下的热量，使咖啡保持在一个适宜的温度。

有人担心Coffee Joulies的不锈钢外壳以及内部神秘的材料可能会危害人体健康。事实上这些豆子内所有的材料都是无毒并且完全密封的。
