Global warming, or human-induced climate change, is a "hot topic" worldwide. Innovations in sustainable energy technologies are being implemented around the world to help reduce CO2 in Earth's atmosphere, with positive impacts on the climate. But even if CO2 emissions trend downward globally, we will not be able to sufficiently mitigate climate change by just replacing fossil energy sources. Dr. Alan K. Miller discusses an innovative engineering solution to removing carbon from the atmosphere. OTEC (Ocean Thermal Energy Conversion)  uses the temperature difference between deep (1000m) cold ocean water and warm tropical surface water to produce clean electricity on the oceans.
