Comments by "Dr Gamma D" (@DrDeuteron) on "EVERY FUSION BREAKTHROUGH…. BUSTED!" video.
Just divide the 1/2 lives: 4 By / 12 years = 300,000,000 now scale by energy 5 keV/4 MeV -> 300K....hmm, not quite billions. edit: wait, that's per nucleus. Per mass, multiply by 80 = 238/3

I blame the tidal wave.

there is no weird physics to be found. The energy scale of fusion (tens of MeVs) is tiny compared with the LHC (14,000,000 MeV, which is fully explained by the Standard Model). You don't even get to' "exotic" (meaning not p, n, e+/-, nu) particles until 105 MeV.

it needs a kick to make a bomb, but look at the demon core: just a slip of a screwdriver, and bzzzzzzzt.

you know you can see the ISS with a commercial telescope, right?

the former requires the weka interaction, which is weak. The latter does not.

Unfortunately, our spent nuclear fuel expert is on the hook for stealing women's clothes from the DC airport.

Matter is not turned into energy. Mass is. 4 baryons in, 4 baryons out. Ofc 2 protons become 2 neutrons, so how do you balance the charge loss.? Two positrons annihilate 2 electrons. Ok then how do balance the lepton number (since matter is conserved)? It’s radiated as neutrinos.

I was at an FFRDC, and our (brilliant) leader said: our job is not to advocate policy, it's to provide correct facts to policy makers. Not sure if they listened to us.

the power/mass ratios are nice. Basically: the lifetime of a hydrogen nucleus in the sun is 5,000,000,000 years, while the lifetime of one in an inertial confinement (laser or weapon) system is around 0.0000001 seconds....24 orders of magnitude faster.

what about the density? I mean Stephan Boltzmann's law say a 150 MK object should radiate enough energy to obliterate the control room.

@steveetches6013 no it doesn't. A teaspoon of 15M degree matter radiates thermal energy at around 70 Mega-tons of TNT per second (this is in fact, how nuclear weapons work: make a small but macroscopic piece of matter that hot), so why doesn't a fusion plasma? Both quantum and relativity break if a hot blackbody doesn't radiate. (obv: it's not a blackbody, then).
