Welcome to today's episode of our podcast.  In particular, we'll be focusing on water power SWAC and DLWC systems. SWAC, or seawater air conditioning, is a promising technology that uses cold deep seawater to cool buildings in tropical regions. DLWC, or deep lake water cooling, is a similar technology that uses cold water from the depths of lakes to provide cooling in urban areas. Both of these technologies offer a sustainable alternative to traditional air conditioning and energy production which are major contributors to greenhouse gas emissions and climate change.
