The Electricity Update! 1.22 maybe?

The electricity or current update should add lithium ore which can be used to power up various new items. Some of my ideas for those items are,

1. Torchlight - can be crafted with copper ingot and wire, iron ingot and lithium. It's reach can be increased with amethyst shard.

2. Headlight - can be crafted with the above items along with an helmet. These can improve mining efficiently.

3. Copper wire - Pretty much self explanatory.

4. Electricity poles - can be crafted using andestine, copper wires and iron ingot. It can be used to power rails.

5. Minecarts (but electric) - these rails are powered using electric poles, these are much faster than regular minecarts.

6. Battery - can be crafted with lithium. 

7. Finally the lithium ore - lithium is actually extracted from some other ore, but yeah. A new ore block would be awesome.
