Yesterday on Modern Mechanix we look at this Japanese radio controlled tank from 1930, an article about the perils of making movies under the sea, a carousel gas station and a fire extinguisher that works by catapulting glass “bombs” full of flame retardant into the flames. Voice recognition 70 years ago? Supposedly this giant TV/Radio combo from 1934 allows the user to change the station just by speaking to it. Lastly we have the debut of the new “De Luxe Sleeper Planes” which actually do look quite comfortable. I suppose they’d have to be considering a flight from New York to LA would take a day or two.
