Bon, je me suis amusé a calculer (approximation à la sixième décimale) l'énergie produite par la désintégration d'un proton et d'un anti-proton.
Voici les données pour ceux qui veulent affiner mon calcul
1eV = 1.60217646e-19 Joule
1 proton = 1.672623e-27 kg
1g de proton = 6.143929e23 protons
dans une désintégration p et p* dégagent E=0.23e-9 Joule
ce qui fait une énergie dégagée de 1.413104e14 joule pour 1g
soit 4.477855 MW pendant un an !
en approximant on peut dire qu'un gramme d'anti-proton peut fournir une puissance d'un mégawatt pendant 4 ans (avec un rendement de l'ordre de 90%).
Tout à un prix, même les hommes ont le leur.
