Just made a topic which gave me this idea, found your thred and thought this was the places to put it :D
Now, we have our basic battery in this game, with its dual purpose of creating and storing energy. However, thanks to this the battery is good at both purposes but exceeds at nither. Therefore, I purpose a new storage block, and 2 new energry creation blocks.
1. Conductor-Crystal
Thanks to new (and expensive credit wise) technology, this new crystal-based machine allows 2x (or 3x not sure if it would be OP then.) as much storage of energy than your basic battery!
2. Cold-fusion drive
The new advances in cold fusion tech alows for a compact generator to be put on your ship! Fuled by the water-creator you brought with you (you brought one right?....) this generator can produce 2-3x as much as your basic battery can! Also as an added bonus, since this technology is powered by water a enemy laser impacting it will not result in a explosion! (Sorry everyone...)
3. Space-fabric generator
If you've traveled super fast in space, you know of the weird effect of breaking the space fabric as you go faster and faster. However, did you know that breaking the space fabric by going hyper speed produces large amounts of energy? Thats right, now you can go super fast, and get super power! A perfect way to keep your engines going for longer when going into FTL! There is a small problem though... If you are planning to keep in FTL just by these I should warn you, due to my failure of making giant explosions on this list, (and the experimental side effects of this tech) these blocks are EXTREMLY EXPLOSIVE. If your reving this thing up at max, crusing in FTL and it gets hit by a laser or missle, say goodbye to your million credit ship.
Disclamer:Due the the experimental nature of most of these objects, expect to open up wormholes, be subject to insanity and time travel, and sudden apperances of black holes and paradoxes.
