Controlled Nuclear Fusion has less than one millionth the efficiency necessary for commercial viability

So far, in the experimental reactors used to test the viability of controlled nuclear fusion as an energy technology, less the than one millionth the energy required for a practical power source has been steadily produced, over a period of a year of operation. Now, to be totally fair here, these experimental reactors were never really designed to produce energy steadily. They only operate for perhaps a few milliseconds at a time. Over a period of a year, they may only be producing energy for a few seconds. But, even during these seconds, the energy produced is very rarely as much as is required to operate the reactor. And, perhaps 50 to 100 times the energy required for operation must be produced, in order to ensure commercial viability. Bearing in mind that there are some 31,500,000 seconds in a year, we can arrive at the conclusion that these experimental reactors are less than one millionth the efficiency required for commercial viability. Actually, perhaps a billionth of the efficiency required. But, what of the controlled nuclear fusion reactors that are not merely experimental, but, are actually designed to produce energy steadily? Surely, they would approach the desired objective more closely? Well, certainly there are innumerable designs for such reactors, that produce energy steadily, and all of these designs do indeed predict results that approach or exceed the parameters required for commercial viability. There's a problem here, though. Whenever anyone actually attempts to build and implement any of these many fine designs for controlled nuclear fusion reactors that actually produce energy steadily for years, they don't work. At all. They don't do anything. They don't produce any energy at all. Ever. So, effectively, in terms of the proven capacity of nuclear fusion reactors to produce energy, we are left with the experimental reactors by default, having no actual functioning nuclear reactors of any other type. Now, of course, we have many, many nuclear fusion researchers claiming quite insistently that they know with absolute certainty that their designs will work to produce energy steadily, once built. They are lying. Quite obviously. And they are costing tens of billions of dollars with their lies. The problem is simply that we cannot obtain a limitless source of energy that is risk-free, radiation free and poses no dangers at all from terrorist use. We have actually had effective nuclear fusion for over seventy years -- the H-bomb. But, the H-bomb is dangerous. And, working on H-bombs to make them more practically useful is dangerous. And, allowing private entrepreneurs to work on H-bombs to improve them, would be very, very risky. So, we don't. And, so, we have no progress whatsoever in nuclear fusion. All we have, are hucksters claiming that their ridiculous designs for safe controlled nuclear fusion work, when they don't, at all, ever.
