I don't think 10x density is possible without getting into nuclear, at least not with the chemistries we know of today, everything at a certain point becomes an explosive.
Speaking of nuclear, getting tons of the material that powers mars rovers and putting them in every home would generate enough power for decades... At the cost of being able to build a nuclear bomb in a garage.
The next revolution will be small scale generation. Fuel cells, extremely efficient cheap solar, even smaller modular reactors, etc.
I live in western Pennsylvania and have both natural gas and electric service, a roof and 1/3 acre of land to utilize. I would love to get rid of at least one of my utility bills and I’m becoming more interested in decoupling from the electric grid than natural gas service. I dream of a future where competition comes to monopoly utilities by way of direct competition with each other as there is a not so far off future where I can utilize solar, batteries and a natural gas fuel cell to cut ties with my Electric Utility. If that kind of competition can exist then the game is on for those utilities to start fighting for customers.
With modern heat pumps and induction stoves getting off of natural gas is fairly easy for most people and saves money in the long run. Meanwhile the grid is switching to renewables so getting off gas is your best investment. You can get of electric too, but on your 1/3rd acre that probably means significant lifestyle compromises - I will be impressed if you are willing to live with them.
Batteries are cheap enough to build (using a commercial installer completely kills the economics, because you're paying five to ten times the actual cost in the US) a reasonable size personal battery bank (~100+ kwh), paired with some overkill solar, to totally replace the grid in a lot of cases. GP isn't limited to rooftop solar with 1/3rd an acre, so they can do it quite cheap if they want.
I seem to remember recent advances in TMSR research and construction. Those tend to e much safer and have safer byproducts than uranium or plutonium fueled water-cooled reactors.
In term of dual use nuclear seems culturally radically different from everything else, wondering why.
