> First, as I already said,it requires negative energy. Not anymore. [1] > Second, it requires a huge amount of that. That's a matter of scientific and technological advancement. All engines gets improved over time, needing less energy. There are already some proposals that lower the energy required to that of an alkaline battery. [2] > Third, the energy is not conserved This escapes my knowledge.
