Ep 18. Liter of Light

Innovation Nation season 1 episode 18 titled "Liter of Light" explores an innovative solution for lighting in developing countries and highlights the efforts of a non-profit organization called Liter of Light. The episode is hosted by Mo Rocca, who takes the viewers on a journey to the Philippines to learn about a unique project that uses plastic bottles and water to bring illumination to impoverished communities.

The episode begins with a brief history of electric lighting and how it has revolutionized the world in the last century. However, the show points out that 1.2 billion people still lack basic access to electricity worldwide. In this context, Mo introduces the audience to Illac Diaz, the founder of Liter of Light, who came up with a cost-effective and eco-friendly way to provide lighting in areas without electricity.

The concept of Liter of Light is simple yet ingenious. It involves creating a solar bottle bulb by filling a clear plastic bottle with water and bleach, installing it through the roof ceiling of a shed or home, and allowing the sun to refract through the bottle during the daytime. The result is an illuminating effect equivalent to a 55-watt light bulb that can provide light for up to ten hours a day without any electricity.

The episode follows Illac Diaz and his team of volunteers as they visit various communities and install these solar bottle bulbs for families who have never had electricity in their homes. The show captures the emotional reactions of the recipients who express gratitude and amazement at the newfound illumination in their lives. Mo Rocca also gets a chance to speak to some of the beneficiaries and understand how this invention has affected their daily lives, enabling them to study, cook, and do household chores even after sunset.

The show also offers a backstage look at the process of making these solar bottle bulbs. Mo Rocca meets the engineers and designers who work at the Liter of Light workshop and explains the science behind the invention – how the water refracts the sunlight, creating a bright glow without any cost or carbon footprint. The episode highlights the impact of this invention, not only in terms of lighting but also as an avenue for job creation and skill-building in local communities.

Apart from showcasing the Liter of Light project, the episode also features other innovative approaches to sustainable energy. Mo Rocca visits a company that has developed a wind turbine that harnesses energy from the movement and turbulence of vehicles on highways. The show explains the science behind this concept and how it can be a viable source of renewable energy for urban areas.

The episode concludes with a segment that highlights the importance of innovation and creative thinking in solving some of the world's most pressing problems. Mo Rocca reflects on how simple yet effective ideas like the solar bottle bulb and highway wind turbines can make a significant impact on people's lives and the environment. The episode encourages viewers to think critically about the challenges we face and how innovation can offer solutions that are both practical and sustainable.

In summary, Innovation Nation season 1 episode 18 "Liter of Light" is an informative and heartwarming exploration of an innovative solution for lighting in developing countries. The episode showcases the efforts of Liter of Light and its founder, Illac Diaz, and demonstrates how simple yet effective ideas can change lives and create a brighter future for all.
