Dr. Russell Sharp explores the promise of direct air capture (DAC) as a way to enrich CO2 for hydroponic and greenhouse crops without burning fossil fuels. He discusses a Japanese company (Seibu Gaiken) running successful trials that showed average yield increases of about 20%, and compares DAC to other CO2 sources like breweries and biogas.
The episode highlights key caveats: DAC’s climate benefit depends on clean energy, units are currently large-scale, and they change heat management compared with gas burners. Dr. Sharp invites listener experience and feedback on whether vertical farms or large greenhouses will adopt this technology first.
