56. Dr. Philip Lubin: Planetary Defense and Large-Scale Directed Energy

In this episode, Peter Garretson talks with Dr. Philip Lubin. Dr. Philip Lubin from the 

UCSB Experimental Cosmology Group. Dr. Lubin discusses his groundbreaking work in laser technology and planetary defense, emphasizing the critical importance of protecting Earth from asteroid and comet impacts through innovative methods like directed energy systems and fragmentation techniques. 

He introduces his unified planetary defense system concept called “Pulverize It”(PI), which utilizes existing launch vehicles, and explores the potential of large-scale laser arrays known as “DE-STAR” for various space applications, including power transmission and enabling faster space travel. The conversation focuses on developing a practical and affordable planetary defense system using current technology, with plans to present this concept to key decision-makers.
