"Turn Break Exception-2: You can declare EM during
the Defensive Fire Phase of Impulse #8 but delay its
activation (and paying for it) to the Energy Allocation
Phase of the next turn. However, if your ship lacks the
energy to pay for EM at that time (or declines to do so)
the ship is destroyed by the destabilized warp field."
So if I have no friendly [or otherwise] ship or planet to evacuate to, in order to self-destruct, it doesn't matter anymore!
Because now I can simply declare EM in Impulse #8 of a turn, and then bottle out on Impulse #1 and not pay the energy, then my ship will blow up
