@Atrayin(View Post) it's good, but alot of the photons are wasted by the void. It also needs to be much hotter, your gol heating system is using unstable forms, I recomend you use a 3 by [any number] block of "WALL" gol, they are alot more stable and efficient. I also strongly advise you use a green filter, this will double the power because green photons are absourbed by lava (red photons are reflected). You don't really need a cooling system, all you need is a bit of INSL inbetween the silicons and PCLN, the spark will still jump through.
