I do lower tech stuff, but small nuclear power plants would be great! Those would free us up to focus more on agriculture, equipment and transportation. With more competition in battery production in conjunction with the new power source, we could even narrow that down to two general efforts: agricultural and equipment (equipment built and developed with free and open source designs...had to happen sooner or later).
Ah, make that three with the efforts for building construction. I’m helping a little toward developing strategies against regulatory problems (mechanical codes).

Think about all the argreculture waste in millions of tons each year and the costs to get rid of corn plant wastes.
Now imagion that waste can be turned into bio fuel as in pellets to burn in a pellet stove.
Even walnut shells, peanut shells can be burn in a gasifier that can run a internal combustion engine.
During WWII most of your Scandinavia countries ran their cars, trucks, buses off of wood gas from a process called gassification, yes it’s true, a car can be run off of wood.
