A few suggestions

[starhaiden]

1. Black hole storage:

• A block that stores possibly 10 times more blocks than a empty space or what ever the dev plan.
• You connect it to the storage control block
• When hp is depleted the block explodes and causes 500 damage to blocks within 4 blocks on it and all items stored in it get spread out

2. anti-gravity storage:

• A block that stores possibly 4 times more blocks than a empty space
• Connect it to the storage control block
• has low hp
• stored items weigh 1/2 the mass compared to in an empty space.

3. Flora:

• carnivorous plants that eat the player
• seeds or the ability to plant plants
• cyborg plants that shoot lasers, at enemies, could act like a small turret, loyal to those that plant it.
• trees
• rare flowers that are protected by something (could be a mission to get one)
• some plants that produce special minerals used for various things
• plants that attack non natural materials

4. Blocks:

• A special block that has the maximum hp and amour hp, to act as a damage absorber
• Bio armour that regenerates

power: (some/most probably suggested)
5. Gravity to power transfer:

• Some sort of power block that converts gravity into power, maximum could be 1000 e/sec per block, planets could have a maximum amount of gravity that could be absorbed by the blocks, (maybe if the blocks absorption is more than what the planet produces, the planets gravity is neutralised.) Planets maximum could be decided by size of planet.
• Worm holes could have an maximum power production of 2 million.

6. Steam power:

• Cheap to produce
• Uses ice and lava to produce power
• Rock and water are produced as a by-product
• Could produce 300 energy per pair of lava and ice
• Has a control and module block
• Lava and ice is placed in control block or chest that are connected
• Each module consumes one lava and ice a second

So what do you think?
