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?
People like to claim that blockchain will sold world hunger but really it’s just a database system so unless your problem is database related blockchain isn’t going to fix it.
The problem they tried to use blockchain to fix was I don’t like the government controlling what I do with the money and knowing I commit crimes. Which isn’t really a database issue it’s a getting caught issue. If you don’t get caught you don’t need to use bitcoin and you don’t need to use blockchain.
Blockchain is a massive innovation for certain industries. Tragically at this point when I read it, I default assume it’s a buzzword techno babble selling point for a system that absolutely doesn’t need it.
