The problem is inefficiency; even Dr Wang's world-leading capsules can only produce 1.6 litres of water per kilogram of lithium chloride over the course of ten hours in very arid conditions.

问题在于效率低下；即使是王博士的世界领先的胶囊， 在非常干旱的条件下， 每公斤氯化锂十个小时也只能生产出1.6升水。

With this in mind, an engineering team led by Peng Wang at King Abdullah University of Science and Technology in Saudi Arabia studied the effectiveness of hollow nanocarbon capsules filled with lithium chloride.

基于此，沙特阿拉伯阿卜杜拉国王科技大学王鹏领导的工程团队研究了填充氯化锂的空心纳米碳胶囊的有效性。
