yes but you will still need fertile material to do so and that is still limited, it is not as if the atoms springs out of thin air.

again if you use a fusion breeder reactor where the fuel goes through several cycles then in essence you would have at least as efficient a system.
any claim as to how long we have fuel for for such a system is well above ad beyond anything remotely achievable by fission on earth alone.

but again my argument is not that it is a viable short term energy source, but that it will be able to provide and sustain a higher energy output overall, fusion simply yields vastly more energy compaed to mass expended, the loss of that energy after its produced is an engineering qestion, in some designs it is as previously stated a non issue, in others the reason they dont work, if the previosuly quoted article employed pure he-he fusion in their next stage of research then the energy would be transferred to the EM field with almost no loss or delay and since it is pulsed in the time frame of a 100 nanoseconds with limited fuel then any heat loss or loss of containment is extremely minimal.

theoretically it should scale very well, if they reach breakeven by next year we might even know within the next 5, if it works one needs to be able to repeat the process quickly enough to actually be feasible for continous production.

if i had the choice of what to do i would still use liquid thorium reactors, due to the safety and ease of construction, no high pressure vessel to blow out either.

again… LFTRs…

fusion can wait, and will work someday. no hurry.

LFTRs can do the job in the meantime.

One of the most efficient types of fission reactors for generating electricity is the Nuclear Lightbulb reactor which uses gaseous nuclear fuel rather than solid or liquid fuel.

spot on.

Gascore reactors produce a lot more heat than solid core or molten salt reactors. The higher the temperature, the more Gibbs free energy is released, and the greater the efficiency. So in short, gascore reactors could produce the most amount of electricity.


Even if and when fusion reactors can produce more energy than they consume, the enormous cost of fusion fuel production will make thermonuclear fusion as a means of generating electricity prohibitively expensive and economically unsustainable.
