Naturally, all fusion is solely due to tunneling. Whether in our fusors, BOT, in stellarator, NIF, JET or ITER. Power-out is a factor of power-in within all fusion systems. Fusion will never go beyond the concept of a crap shoot, probability, and being a game of chance whether at 400 watts input or a gigawatt input.
In the matter of fuel, fusion fuel does not want to fuse so even if you have the non-extant on earth, Tritium or the more abundant but still difficult to obtain natural deuterium, you are no where without massive input of energy PLUS a containment field. Fusion does not want to occur even with endless amounts of fuel at hand.
Fission fuel is relatively abundant in selected rock on earth... Once you have the fission fuel in hand, zero energy is required to start the fission reaction. No intense magnetic field is needed to contain it. and, regardless of the fission methodology, more fissile material and even fusion fuel is created amidst the radioactive by products and debris. That is why most of France's electricity is totally nuclear fission today and a significant amount of our electricity is also fission based.
The only demand made on earth bound fission or fusion is that the fuel must have a neutron or an over abundance of them. Neutrons within all nuclear fuels are the key to both reactions on earth.
True protium will not fuse until confined in the core of a star and the best reactions don't occur even in the core at a useful rate until deuterium is produced which means until the neutron is created creating a decent cross section amidst the nuclear fuel in the core of the sun. The first fusion in a star creates the neutron. Neutrons, on their own, have no normal, natural existence as they are all radioactive with a short half-life.
I have always felt that the strong force only exists within the bound neutron in the first true atom, deuterium. We have never seen a 2P atom even in the supposed and predicted p-p fusion, deuterium is the product.
There are no proton stars! Neutron stars are well known and recorded.

Fusion is the energy of the future....and it always will be
The more complex the idea put forward by the poor amateur, the more likely it will never see embodiment
