The solution was not Adding Auxiliary Power...

[Dire Venom]

I like the idea of unstable power but is it necessary to introduce a new block? Maybe a an option (similar to the thruster settings) for "overdrive" would do the same thing. In that case you could choose between low but save or high and dangerous supply.

If the explosion can affect other blocks I would build a warp core that can destroy the whole ship if damaged but offers compact and efficient energy.

This is a brilliant idea :3
A way of boosting systems, except with a very explosive consequence if your not careful.
