I'm way out of my knowledge here, but google tells me: - a Deuterium-Tritium fusion event releases 4.03 MeV - 1eV = 1.602 x 10^-19 joules. - That means each helium produced comes with 6.5 x 10^-13 joules of energy. - One liter of gas where humans live has 2.6 x 10^22 molecules. - A small balloon contains about a liter of gas. (ok, I made this one up.) - I think gaseous helium is just single atoms. - One liter of helium produced by fusion came with 6.5x10^-13 * 2.6x10^22 joules of energy, call it 1.6 gigajoules. - 1 joule = .24 calories ... 384 megacalories. - Figure the thermal mass of the experiment was about like 1kg of water (desktop scale)... the experimental apparatus would be 384000 degrees celsius (not recommended for desktop scale). I'm guessing I can detect the temperature first. (Bonus calculation, 1 liter of helium production also matches the energy released by 382 kg of TNT.)
