Incomplete Resolution of the Possibility of Low-Energy Nuclear Reactions
While low-energy nuclear reactions (LENRs) have received substantial attention and there is no good evidence they exist, there may still be other mechanisms or parameter combinations that are underexplored.
Foundational Capabilities (1)
Design and implement experiments to rigorously test low-energy nuclear reaction principles, providing clear data on reaction mechanisms and viability.
This is highly speculative and at this point unlikely to yield practical LENR, however, see: https://coldfusionblog.net/2019/03/13/the-case-against-cold-fusion-experiments/
