Realistic Batteries. It's holding back a LOT of things. A lot of technologies are solved, but just require power.

Semi-Realistic Room Temperature Super-Conductor.

If that can be solved, the power density and efficiencies would just be astronomical.... It would absolutely destroy multi-billion industries overnight.

Way-Out-There-Stuff If they ever prove out an actual functional EmDrive-like thruster, that would absolutely open up space travel to our species.

Batteries are the big one. Can you imagine how many people (homeowners/renters) will go out and buy a tiny 100W panel knowing that even though it will fill a battery with energy very slowly, they can still bank on it for a week?

Right now we have batteries that can survive about a day, using a modern solar panel system with inverter (~1000€). Imagine when we have batteries that can store weeks of power.

Not only on the large scale of things,

But even robots would be in wide spread use if it had a useable runtime.

Something like this, you're good for 20min before it needs to charge. https://www.youtube.com/watch?v=29ECwExc-_M

But if you could pull that off where it runs for 8 to 12 hours before needing to charge? They would be used everywhere.
