With their powers combined, planeteers Lex and Tony bring you this super-sized episode featuring one of the most brilliant scientists working in the renewable energy industry today. He's Dr. Reginald Parker — aka Dr. Green Power! His base of operations is in "Hot-Lanta" — but the solar panel technology he innovated can be found all over the world. His mantra: "Use energy better and then use better energy!” Listen in as Dr. Parker reveals the genesis of his startup, Optimal Power Solutions, and the positive impact it has on the environment — starting with hospitality! So as the country begins to open up again and you find yourself itching to travel, you just might end up booking a room at a "smart" hotel that's monitored by Dr. Green Power himself through his Artificially Intelligent bots. The upside for business owners? Lower energy costs and higher profits. The upside for us? A cleaner and healthier planet. Last but not least, Dr. Parker unveils how he and his MIT classmates influenced the creation of one of Lex and Tony's favorite superheroes — Captain Planet! Fitting, since this episode was recorded on National Superhero Day. Tune in now for a nerd celebration unlike any other.
