Thorium Dynamo

 is a unit.

Strategy
is an extremely strong economic unit which can almost never be ignored in a set. Because of its click ability, it is viable to get even in sets without units, since the excess  can at least be converted to  (albeit inefficiently). is also a strong enabler of breachproof strategies, since it is not difficult to convert almost all of your Drones into s.

If you are buying s for value but are not going breachproof, you will want 1 to 3 Dynamos depending on how much economy you want before you start full attack production. Even with the faster economy start that provides, with good defense in the set to discourage breachproof you don't always want to wait for 20 income before the switch. The sweet spot if you don't want many Green units is 3 Dynamos, giving you the option to click a every turn without floating.

If you are going breachproof, you want to get 4 Dynamos if possible, because the best defense for your is having more of them. Against aggressive openings, however, it is often better to only make 2-3 Dynamos because your Drones and Engineers can't be defended long enough to assemble the last one and you also need to put the pressure on earlier, so you should avoid overdroning.

Advanced Strategy
Compared to Trinity Drone, generally provides better value, but is less breachproof (and therefore a higher priority target to kill).

If you are breaching an opponent, it will almost always be better to start damaging the s as opposed to attackers. This is because with the s alive, you can usually create breachproof attackers faster than they can be destroyed. This may however be less true if there are not many breachproof attackers in the set, or if supplies are running low.

Knowing this, an option for the breachproof player is to let their first get damaged, but suddenly switch gear to a non-breachproof strategy by starting to absorb. This "fake breachproof" strategy lets you absorb damage on a that will keep value the whole game with without actually being finished off. This is very telegraphed by the buying of the Blastforge. If the opponent can see it coming, they can instead get value by killing off something else (like a Gauss Cannon) or ensure the destruction of the by creating too much pressure for 1 turn of defense via threat or chill.

With in play, Conduits can be bought for a similar value as a Drone, as they provide one  which can be turned to. However, this is very inefficient as you would basically never want to buy a Drone for.

Efficiency
You can think about by comparing it to purchasing an equivalent amount of Drones and Conduits. Suppose you have six Drones and two Engineers. The following sequences result in identical economic outcomes:

Line A (Dynamo)

 * 1) Dynamo (bank 1)
 * 2) (bank 4)

Line B (DD+C)

 * 1) DD (bank 0)
 * 2) C (bank 4)

However, the is buyable even if you only have 5, or only one, whereas you needed  to play DD/C. This may free up to produce more Drones simultaneously. This provides a significant economic advantage in scenarios where you would otherwise have had to e.g. buy a single Drone and bank 2.

Standard opening
Both player 1 and player 2 have very efficient openings that can be followed up easily with any tech.

Player 1:
 * DD
 * 1) D + Dynamo
 * DD

Player 2:
 * DD
 * 1) Dynamo + Dynamo
 * D

High economy
Both players also have builds to get a high economy going while delaying their third Engineer, without committing to more than one green:

Player 1 (starts with the line above):
 * DD
 * 1) D + Dynamo
 * DD
 * 1) Options: Dynamo + Dynamo, DDA, Dynamo + DB or DDBE

Player 2:
 * DD
 * 1) D + Dynamo
 * 2) DDE
 * 3) Options: 3 Dynamos (Extreme follow up), DDDA or DDDB (More conventional)

Wild Drone (1)
 * 1) Dynamo +1
 * 11
 * 1) DDC
 * 2) 2x Dynamo (4GGG left)
