Actually, yes. Nuclear is the cleanest energy out there.
Probably why the enviros are encouraging us to build all of those nuclear power plants. /s
Norwegians, Swedes, and Icelanders are involved in developing a particle physics anomaly into a technology which may upend everyones cart. They have experimental results which suggests an annihilation like process can be induced in a special condensed-matter materialone originally discovered within a prior experiment as a byproduct.
Mesons and decay Leptons are generatedsuch that they do utilize radiation shielding for their experiments. Direct energy extraction from charged particles appears a viable avenue.
