As a car enthusiast, I can think of a good one, the Ford Nucleon.
During the 1950s and 1960s, there was considerable interest in nuclear power and its potential applications. This led to the idea of using nuclear energy to propel cars. The concept behind a nuclear car was to utilize a small nuclear reactor to generate steam, which would then power the vehicle's engine.
Of course back in those days, this was extremely futurustic and some at the time thought this would be a game changer, but ultimately, the safety aspect was one of the biggest reasons why this idea was dropped, and I probably don't have to explain why it may not have considered to be safe, I mean, it was using nuclear power, so even if the engineers tried to make it as safe as possible, IF something went wrong, it would have been catastrophic.
Ever since then, the interests in the automotive sector has shifted to Electric and Hydrogen.
Still, a very intriguing concept car and idea.
Outside cars, you have blimps, and I personally believe if we tried to make something like a hindenburg today with existing technology, we might have been a lot more successful than back then (as it goes way back to 1930s), there are still some blimps used occasionally, I also don't believe those use hydrogen(?), but they are not the "game changer in air travel" it was once seen as, although we can't rule out a comeback.
What about you guys?
3D TV.
Let's be real: most of us knew it was a shitty gimmick.
Both times.
This was my favorite tech of all time. I don't think most people ever got to try it where it worked without glasses.
I loved 3D movies and still do. Ultimately people don't like wearing shit on their face or having to hold their heads in a certain position (inb4 the one eyed people and the people who get nauseous chime in), but oh well - I'm glad I was able to really enjoy the experience when it was at its peak
I really enjoyed it on the New 3DS. It didn't use glasses and being handheld you were always positioned perfectly. Given it has been another decade and higher resolution that tech would be amazing in a smartphone.
Fun fact, I'm blind on one eye and so 3D TV never worked for me. The whole thing of seeing stuff coming out of the screen requires two eyes lol
To be fair, that applies to real life also. The sense of depth from a single eye comes from your brain interpreting cues like shadows. I wonder if that makes you more attuned to regular flatscreen 3d so it's more immersive to you than the average bear. You were definitely not their target market!
Damn bro haha
