Some people say things like electric vehicles aren't feasible. In addition to all the EVs that have been on the road for years, we now have electric powered ships that can cross the ocean to add to the evidence that their theory isn't looking so hot.

Why not just use nuclear power on ships?
Some submarines already do.
Yeah, so I've never understood why it never spread from there.
Probably because it's so expensive and nuclear fuel has such tight access controls. It's only militaries that use nuclear powered subs (and possibly ships as well?) The idea that a ship could be taken over to obtain materials to build more nukes isn't one that the superpowers are keen on.
Also, ships tend to sink sometimes and having radioactive material at unpredictable places is probably not good.
The oceans are full of uranium.
You mean like the US uses. Lol
Genius actually
Seems like it's still a "pie-in-the-sky" thing. We don't have electric powered ships. We have imaginary designs and one untested prototype battery.
“We now have electric powered ships”
The electric powered ship: 
They are not even close to feasible for everyone to use them. The power grid is not even 20% the way there.
They won't be what we drive in the future. Likely hydrogen, perhaps nuclear.
Hydrogen/ammonia for ships and possibly aircraft
Nuclear to power nearly all base level production including powering H2/Ammonia production as it is most dense energy source I know of
Battery electric fantastic for short range like cars and bikes and tractors etc, or also hydrogen fuel cell if developed and adopted like BEVs.
Anyway the future is bright and abundant with reliable accessible energy
Let's keep building 💪
And use bitcoin through it all 🧡
