我们的星球上有71％的水覆盖，但只有大约3％是自然形式可用的淡水。海水的脱盐一直是科学家中感兴趣的话题，因为它可能导致全世界的潜在突破。牢记这一点，总部位于伦敦的太阳能水公司最近与沙特阿拉伯政府签署了一项协议，这是他们未来5000亿美元的“ NEOM”项目的一部分，以实现绿色，更清洁的未来。该公司的目标是建立“使用太阳能圆顶技术的第一个淡化厂”。
太阳圆顶植物基本上是“埋在地下的钢锅，上面覆盖着圆顶”，从而使巨型球的外观。玻璃圆顶被反射内部太阳辐射的Heliostat反射器包围。辐射用于加热圆顶内的海水，从而蒸发并凝结形成淡水。根据太阳能水首席执行官David Reavley的说法，该技术便宜，快速建造和中性碳中性，因为它不利用像其他脱盐技术这样的污染纤维。
There are still doubts about the mass-scale production of these solar water domes and if Solar Water can pull this off in their PLC 2021’s experiment, then it would prove to be a huge step towards a new carbon-neutral desalination technique that doesn’t need a lot of electricity nor polluting chemicals to operate. There are other companies such as Climate Fund Manager and Solar Water Solutions, that are installing about 200 carbon-neutral desalination units in Kitui County, Kenya with the aim to provide clean water to 400,000 people by 2023. For countries in the Middle East, where there is scarcity of rainfall and freshwater resources, the construction of solar domes by Solar Water could prove to be a great asset in the future.
