The Czar Bomba is a radical new "pulse" based reactor design, only able to operate on pulses of a second or two without overloading. this is accomplised through the use of a redstone switch and an inverter hooked up to a button. It is only able to do 4 pulsed before it must cool down, is extremely resource intensive, and outputs almost as much power as a pulsar star, able to overload an hv transformer, and, after 4 pulses, has outputted over 400,000 Eu.
Edit: only puts out around 100,000 Eu i mixed up my math, although this number will increase if ther are more recievers more on this at a later date
