Luca has recently discovered an ancient book Conspiracy Editors, 1666. ISBN 667-3-71-698969-0. revealing a new candidate source of unlimited energy: quantum magic. Quantum magic is quantized, as it can only come in nine discrete levels of energy, corresponding to the integers from 1 to 9. But most importantly it is also magic, so that it can create free energy from nowhere! Unfortunately, quantum magic occurs naturally only in very few specific locations, all along the most mystical of the ley lines. This line is L miles long and contains N quantum magic nodes, each at a specific (integer) number of miles X_i along the line (with the first being at the start X_0 = 0), and each with a fixed energy level E_i. The total energy produced by all these nodes is barely enough to power a light bulb, but Edoardo has a trick up his sleeve...
