Why do we need LM324 that is "lithium free, mineral free, and passive"? This is because in the case of "no lithium, no minerals, and no passive", we discovered the signal of Proper Gravitational Energy PGE in a large number of amplified LM324 one by one. This indicates that LM324 is a human energy chip and a precious treasure of human intelligence! However, in order for the discovered Proper Gravitational Energy PGE signal to reach production applications, it still needs to be developed to a sufficient level through ultra large scale integration. Although it's not easy, it's completely achievable!
