  • Running Dry

    In this episode of the Knowledge Drop podcast, we take a deep dive into the "water crisis" in Arizona. With the current boom in housing development, there are growing concerns about the sustainability of the state's water resources. We discuss the recent denial of a building permit on the grounds of insufficient groundwater and explore the different water sources in Arizona, including the Colorado River, groundwater, rivers, and reclaimed water.

    We also examine the current Lake Powell levels and compare them to historical averages. Drawing on sources like NOAA, EPA, Times Magazine, and Columbia University, we look at potential solutions to the water crisis, such as water desalination, pipelines, importing water, and conservation.

    In particular, we focus on atmospheric water generation as a promising and innovative solution to the problem. Finally, we challenge the conventional wisdom that fresh water is scarce, pointing out that the real issue is a distribution problem. Join us as we explore the complexities of the water crisis in Arizona and the potential paths forward.

  • H2O to Go

    Welcome to this episode of our podcast, where Josh and I explore the fascinating world of hydrogen fuel cell technology.

    Hydrogen fuel cells are a promising alternative to traditional fossil fuels for powering vehicles and generating electricity. Unlike gasoline-powered vehicles that emit harmful pollutants, fuel cell vehicles only produce water vapor and heat. Additionally, hydrogen fuel cells can be used to store and generate electricity, making them an attractive option for renewable energy storage.

    Next, we'll take a look at the current state of hydrogen fuel cell technology. We'll discuss the progress made in recent years, including the development of fuel-cell vehicles and advancements in the production and distribution of hydrogen.

    We'll also address some of the challenges that still need to be overcome, such as the high cost of producing and distributing hydrogen and the limited availability of hydrogen fueling stations.

    So, join us as we explore the exciting world of hydrogen fuel cell technology and its potential to change the way we power our world.
