I just started listening to this podcast, and I'm loving it!
Very interesting stuff, and well presented. The host Mr. Cage is doing a great job keeping the conversation going and asking great questions (the kind of questions I would ask.). It's been years since I've subscribed to print edition of Pop sci, but I think this podcast is pushing me to want to subscribe (I like the mix of reading a mag, and listening to the podcast about it.)

When it comes to alternative fuels, I really think the sucessful ones will be one that fits neatly into the American infrastructure. If it can be easily distributed at gas stations, then the barriers of moving towards it become trivial.

Keep up the great work, Chuck!
