Okay, I have had a idea for some time and I want to see if it will work. first you get Magnesium 24 launch protons at 20 Mev then a decay happens. Now you have Na22 sodium 22 beta positive decays into a anti electron of 1 Mev with its counter particle they annihilation into 2 gamma rays which produce heat due to electrical resistance now you use that pressure to make electricity. you lose all but 1/20th but you have a battery of 80,000 j/s for 2.6 years or 28 Tj/kg over half life then it halves at a slope but i do not want to calculate that. Mass into energy in a small area you have a long source of energy for robots and stuff. EQ = ((6.022 x 10^23/22000) = 1 mev = 1mev *( 6.022 x 10^23/22000) * 1..6 10^-19 = 80,000 (j/s) 1/20th, small container super conducting accelerators-------> decay force ----------> anti-matter annihilation------> Heat or electricity. alot of energy in a Small container more than every oil barrel on the world. That is what I was thinking, Is it possible?
