Modern-Mechanix Round-UP

Today on Modern Mechanix we looked at this gasoline powered radio that gets 160 hours of playtime per gallon, a pretty precarious looking sled-bike, a lengthy 1931 Popular Science article about evolution, and a 1928 plan for passengers in a hurry to be loaded into bi-planes and catapulted off of the deck of ocean liners when they get within a couple of hundred miles of their destination. We also learned how scientists of 1947 planned to raid the ocean floor and that automobiles are not popular in Holland.
