Step back in time with this in-depth look at the Popular Mechanics January 1971 issue, where we uncover some of the most fascinating and wild inventions, trends, and technology of the era! The magazine kicks off with a DIY project to build your own RV using a van’s frame—a concept that was surprisingly legal back in the day. This issue dives into motorsport crazes like Formula A racing, drag racing, and stock cars, while Champion spark plugs reign supreme. We even take a trip through vintage cigarette ads, where brands try to sell an idealized lifestyle and poke fun at people who don’t smoke their brand.
On the tech side, we explore early digital computers with models like the 70.683H and 70.342H—massive machines that were just beginning to revolutionize the digital world. Then there’s Cartrivision, an early home video recording and playback system that used large, clear video discs stored inside cartridges. Before VHS and Betamax, Cartrivision offered the promise of watching movies at home, though its high cost kept it out of reach for many. The article breaks down the different spooling types for digital cartridges, explaining formats most of us have never seen, like stacked and side-by-side reels. Cartrivision’s standalone video deck was about the size of a small heater, and while this tech was groundbreaking, it remained too expensive to see widespread use, especially in rural areas.
But that’s not all—this issue is packed with quirky inventions, including ads for hot air flying saucers, snooper-ear listening devices, and ski props. The ATV scene is also in full swing, with racers tearing through courses in adorable, 6-wheeled all-terrain vehicles. We also discover some truly bizarre tech, like implanting radios inside teeth!
Things get even wilder with an article on super mini snowmobiles and a British experiment where chickens were fired at planes at speeds of 700 MPH to test for damage. And let’s not forget the iconic, yet dangerous, 3-wheeled cars that were notoriously unsafe but incredibly fascinating.
For those interested in futuristic concepts, there’s a glimpse into a monorail system designed to help disabled individuals move around independently—an innovation ahead of its time. Whether it’s cutting-edge tech, dangerous vehicles, or DIY projects, this issue of Popular Mechanics gives us a look into a unique era where innovation met risk head-on.
If you’re a fan of retro technology, odd inventions, or just curious about what people in the 70s thought the future might look like, this video is for you!
