 ionizers based on existing rainfall generation technology, indicate that the majority of the rainfall generation occurs within approximately 60 miles of the ground-based ionizers. This range allows for placement of the equipment to optimize for the cost of land leases, as well as predominant wind flows. By installing multiple systems at appropriate ranges away from the desired impact area, RWT’s approach would allow for enhanced rainfall with high level, broad-based targeting, by synchronizing the ionization on-off with increasingly accurate weather information and forecasting. RWT is in the process of partnering with ground-based radars and satellite imaging for optimal and powerful real time weather forecasting data access. In addition, RWT expects that its systems will be able to be manufactured and installed in approximately four to six months, which differs from the desalination process that generally takes several years to obtain permits and build associated energy generation. RWT believes that the expected rapid time-to-market and anticipated use of off-grid solar and wind power systems will provide an advantage in addressing water scarcity in the coming decades. Initial installation would be more costly than the cloudseeding approaches and requires a small amount of semi-permanent land to operate from. However, RWT’s system would be able to operate continually up to 365 days per year, and key post-installation costs would be modest, including electricity and monitoring. Once installed, the system is expected to use approximately 600 kwH of energy consumption per year. Reliance on natural updrafts would limit targeting but would minimize energy use and avoid using chemicals in the rain enhancement process. Ultimately, some of the water that condenses due to RWT’s operation will come out of nearby oceans per the established “water cycle”. In Oman, over a six-year randomized third-party trial from 2013 to 2018, an ionization rainfall generation system based on existing technology generated an average of approximately 16% of additional rainfall according to results published by the National Institute for Applied Statistics Research Australia (“NIASRA”), a third-party research organization, in the International Statistical Review. Three years after this trial occurred, news reporters in Oman continued to report enhanced rainfall as compared to prior years when the hardware was not operating. In addition, trials performed by third-party individuals funded by the National Key Research and Development Plan of China and the National Natural Science Foundation of China in the Wushaoling and Liupan Mountains in China also indicate that an ionization rainfall generation system helped increase rainfall in the area by 20%. RWT believes significant improvements from software, synchronization with real
