Season 4 Finale - Sunlight‑Powered CO₂ Capture & K‑Pop Carbon Tales

In this Bite‑Size Climate Tech finale, Dr Anna de Vries takes us from lab bench to lemonade stand to explain how photoacids could make carbon capture cheaper and greener. Traditional systems use heat or electricity to release CO₂, but Anna’s solution uses light‑reactive molecules that switch from alkaline to acidic under sunlight. In darkness they flip back, allowing CO₂ to be captured again. This swing cycle runs at ambient temperature and pressure and requires far less energy than conventional methods.Along the way, we explore how this new science ties into pop culture (yes, there’s a K‑pop “soda pop” reference), why a young researcher chose climate tech over other paths, and how a cultural shift among the wealthiest could drive climate action. Anna closes the season with a simple message: no impact is too small.
