A fusion reaction won't work to destroy the planet because the bulk of the materials when fused give a net energy loss.
True, but as you get heavier you get less energy and less net energy gain if even that.2) The lighter the element used as fuel, the more energy you get out of the fusion reaction, and it is not until you start fusing iron that you get a net loss.
It's at iron that no matter how efficient you can fuse the materials it won't produce net energy gain, but even that can happen below iron if your process isn't efficient enough
Yes; it would be a better idea to just use force rather fusion.3) I'm not sure you even need to start a fusion reaction, and if you did, you'd have a star that was going to go nova.
That's because of the way a supernova happens:4) When a star dies it fuses things heavier the iron, and yet still goes nova.
1. Star starts fusing elements into iron.
2. Core is iron.
3. No energy is holding back gravity.
4. Star implodes.
5. when it hits the solid iron core it bounces back and explodes.
The elements heavier than iron are being produced yet the star goes nova because that loss of energy holding back gravity is what triggers the supernova.
