Look at the bottom entitled "Inventions You'll Never See'.
As you see each picture, read the blurb to the right,
using the tiny scroll bar located there to get all the
information.
Some of the items on the list, like the streetcars, didn't make it for economic reasons and/or lack of consumer interest, like streetcars ... people wanted their automobiles, and the culture came to revolve around them.
Others, like Tesla's free energy, didn't make it because there wasn't an economic model for making a profit that would support its development and the enormous investment that would go into it. And as I recall, he was playing with the concept but I don't think he had a fully working device. And the concept wasn't that there was no cost to creating the energy: it was a way of broadcasting energy without wires. You still had to generate the energy that you were broadcasting.
Still others on the list are just wacky or quacky, like the car that supposedly ran on water (I remember this hokum from my childhood in the 50s) or the miracle cancer cures. I'm surprised Huffpo didn't include a perpetual motion machine or two in the mix.
The results of Fleischmann and Pons' cold fusion experiments couldn't be replicated. However, research is ongoing in various places. I wouldn't give up on cold fusion just yet. They've been trying to develop hot fusion for decades with little or no progress.
Random sequence combination locks
Dark bulbs (that way you can play night baseball during the daytime)
Steamer trunks that lock from the inside
Flat head (slot) metric reversible screwdrivers for left handed people
Ice cube tray demagnetizers
Microwavable lettuce
Left handed basketballs

Maybe they actually read that the patent office now routinely rejects perpetual motion machine claims outright because of the violation of fundamental laws of nature. In this specific case, they, the patent office, demand a working prototype which they don’t do for many claims.

And the ones which 'work' are classified. Yep, good plan.
