That's easy. Writing books and researching curiosities.

I have dozens of book ideas, from novels to reference volumes. My research would at least partially focus on energy/power generation/storage, and partially on current scientific mysteries in our reality.

Ideally, such work could help enrich humanity. Make the world better in some way. Sadly, unless I win a lottery tomorrow or a wealthy person issues me a grant, some of this work won't get done.

You have ideas on power storage?

I'm not them, but recently I've become interested in thermal batteries (aka sand batteries) ala https://www.youtube.com/watch?v=KVqHYNE2QwE which isn't exactly power storage but my house specifically uses 50% of my electricity for the water heater and untold $$$ (and CO2 :( :( ) for the house heater, and thus if I could load up a sand battery with heat and disburse it for hot water and hot air, that'd be swell

Tankless is for sure one fix to that problem, but if I had a magic wand the thermal battery still feels "better" to me
