“…A root inspired solar still from Xie et al demonstrated that a 1-dimensional wick system could decrease the required wicking area to only 2% while maintaining salt rejection. 53 This afforded a freshwater generation rate of 1.5 L m -2 day -1 . A floating solar still by Aye et al used a vacuum pump to increase their freshwater yield to 4.3 L m -2 day -1 , unfortunately this removed the passive nature of the solar still as it required an electrical plug to operate, increasing complexity and cost.…”

Established desalination technologies such as thermal distillation and reverse osmosis require advanced infrastructure and costly installation limiting their widespread implementation. Floating interfacial solar evaporation devices are considered a land-saving, environmentally friendly, and low infrastructure approach for freshwater production. Addressing issues related to maximum heat localization, prevention of salt accumulation and operating under stressful environmental conditions are some of the major challenges with floating solar desalination. This project presents an experimental demonstration of a plasmonic TiC nanoparticle-based floating solar still that can operate continuously under sunlight to produce clean water while floating on saline water sources. All materials, such as the PVC plastic condensation dome, EVA foam support, cotton wicks, and polyester filter fabric were chosen carefully to maximize the freshwater output of the solar still. The outdoor experiments were conducted in Halifax, Canada, where modest solar insolation of around 6 kW m-2 day-1 led to daily water yields up to 3.67 L m-2. The water can be produced at costs as low as $0.0086 L-1, and the solar still can be easily modified to generate thermoelectricity. This could allow for small onboard devices to test water quality without the need for an external electricity source. The results of this study will contribute to further development of floating solar desalination to provide potable water for water-stressed communities.

“…Given this, solar desalination has received widespread attention in recent years. [9][10][11][12][13][14][15][16][17][18] However, the value of daily production fluctuates greatly and is much affected by climatic conditions, which are not easily forecasted.…”

Solar stills are considered an effective method to solve the scarcity of drinkable water. However, it is still missing a way to forecast its production. Herein, it is proposed that a convenient forecasting model which just needs to input the conventional weather forecasting data. The model is established by using machine learning methods of random forest and optimized by Bayesian algorithm. The required data to train the model is obtained from daily measurements lasting 9 months. To validate the accuracy model, the determination coefficients of two types of solar stills are calculated as 0.935 and 0.929, respectively, which are much higher than the value of both multiple linear regression (0.767) and the traditional models (0.829 and 0.847). Moreover, by applying the model, it is predicted that the freshwater production of four cities in China. The predicted production is approved to be reliable by a high value of correlation (0.868) between the predicted production and the solar insolation. With the help of the forecasting model, it would greatly promote the global application of solar stills.
