Elon Musk put out a $100 million prize earlier this year for innovation in 'carbon negative solutions', or pulling carbon dioxide (CO2) out of the air. But BloombergNEF carbon capture analyst David Madrid says Musk is missing the point -- what is needed for direct air capture is scale, not new technologies., This week, Switched On speaks with David about direct air capture, how it works, and the pilot projects aimed at bringing the technology down the cost curve.

This episode is based on a report titled Material Tech Highlight: Direct Air Capture. BNEF clients can access this at BNEF<GO> on the Bloomberg Terminal, or on bnef.com or BNEF Mobile.

Switched On is hosted this week by Mark Taylor.
