Hey guys, I just listened to the show and I'm a big fan of Louis vision and the kinds of projects what we should be aiming for. It was a great show however I'd like to get Louis opinion on the new EM Drive that NASA is currently testing. I'm not an expert however NASA has been trying to debunk this thing for a year and has not been able to. Being an optimist I am hopeful that this technology could revolutionize space travel for us. Thanks so much for putting together such an amazing show! and keep up the good work. -Sai

Very pleasant episode indeed, thanks for this one. That #1 take away for me is the Solar Gravity Lens Focus !!! What are we waiting for?? :) Not one but quite a few probes should be sent out there. Immensely exciting!
