Not a single success has been achieved
On the front of nuclear fusion power, not a single success has been achieved.
The main blocking factor is that it takes a large kinetic force of energy to overcome the electric repulsion of the nuclei that must fuse for power extraction to become possible.
The extremely strong electric repulsion between the fuel nuclei prevents their atoms from merging.
While it is possible to force the fuel atoms to merge, with massive external energy being applied, the output energy that is achieved from the forced fusion is too feeble to cover the input energy needs for the fusion to happen, much less to produce a net energy-gain.
