Kerbal Mining Program

[Turf]

My first challenge I've ever made.

The principle of mining to gain money is simple. You mine using the drill to gather resources, and recover the vessel with the resource. The resource will be converted into money.

Objective: Build a miner (fixed in the ground) to get the most funds in 1 launch in the shortest time.

Rules:

1. Start in new career. Difficulty options set to Normal. Only use stock parts. Use of ISRU converter is allowed.

2, Use of alt+f12 or cheat mods are only allowed to give funds, or science to unlock parts (feel free to unlock entire tech tree), but not for anything other than unlocking parts.

3. Time warp is allowed (because I see some electric consumer generates energy instead of consuming energy in high time warp).

4. Use of an engineer is allowed, maximum 1 engineer.

5. Build it in VAB, not SPH. Launch it in Launchpad, not Runway.

6. Breaking the Launchpad means repairing it again, and the repair cost will be deducted from your funds you get from mining.

7. Mine in Kerbin since you will not go to space today.

8. (NEW) Tell me the versions you used.

9. (NEW) Miner must not launch, it have to stay in launchpad.

10. I can't think of anything goes wrong from this set of rules, so have fun!

Scoring:

Score = (Product ^ 2) / Time

Product (F) = Funds required to build the miner - Funds from recovering the miner.

Time (in seconds). Be aware of what time you are using (Kerbin or Earth)

Background:

The KSC got bankrupt. They have no money to build rockets anymore. Moreover, Walt Kerman is away for vacation (so there is no Bail-Out Grant). Fortunately, there are a banks (Kerbin Banks?) that are willing to give us a loan up to 100000000 Funds. However, the money have to be returned after 1 launch or 1 Kerbin years whichever come first, and no more loaning. If the money isn't fully returned (even missing 1 Fund counts), the bank will shut down KSC (forever?). Completing an interplanetary contract would take more than a year. Completing a local contract yields too little money to fend off the bankruptcy. An important meeting is held for discussing on how to save the KSC. One kerbal suggested to start a mining program. How they will make the most of their miners? Will the KSC be saved?

There are two KSP versions. That means I need to separate two versions.

Scoreboard coming soon.

That's it! If there's any flaw (I am not perfect), please let me know.
