Fusion power tech adapted to ease geothermal power. IMO a good example of remixing knowledge from one domain to another. And, for example, if you think fusion isn't worth pursuing, then we might not get this cross-cutting adaptation that's valuable for advancing renewable energy.

Would be interesting to look at adding a contribution from the Open Energy Modelling Community. Open Energy is concerned with bringing open science practices to the models for planning energy infrastructure. In effect this means how new energy generation and use will be brought online in our communities and cities for rapid decarbonisation. Since this effects peoples surroundings it is valuable for them to be brought into the decision making process - about how models work, options they throw up etc. In Germany this community has been developing in a very interesting way and in the US the first workshop was held in 2019.
