more to the point, there is a volume where the net gravitational field (and orbital forces) nearly balance out. Assuming you are near this place, your station keeping efforts are minimal, but not zero as the location of the 'perfect spot' moves slightly as the moon/earth/sun relationship changes. Multiple vehicles can be in the region with similar energy requirements for station keeping.
Your math is a little off. If the density were the same as Earth's, the diameter would be proportional to the cube root of the mass ratios, or slightly less than 2 times that of Earth. The surface gravity is proportional to mass (7x) and inversely so to the square of the radius (~1/4) so 7/4 is about 1.75 surface gravity compared to Earth. If there were a comparable 'day' length, then the velocity at the equator would be about 2x that of Earth. An extra 1000 mph liftoff boost vs 1.75 local g, not so hard to overcome.
And since we know nothing about the planet other than the mass, this is all silly speculation.
Those who have one idea in a lifetime, and those who have trouble getting to sleep because the ideas keep coming. Which one are you?
If this is it, take the money (not nearly enough to retire on) and get a job (likely with Facebook as part of the deal). Then parley that resume into being an industry guru, and better jobs down the road. Some one(s) will offer you equity in their ideas and board/advisor roles and life can be good.
I am concerned about the long term effects of taking all that power from the Sun. How long before it starts to shine less, or doesn't keep us in orbit anymore. The whole idea of endangering the longevity of the Sun gives me shivers. Think of our children!
depending on the location, a ranch may have no basement. Attic is still an option, although getting to side walls is difficult. Running PVC conduit up (or down) the wall to an accessible location is cheap & easy.
Pex for plumbing, geothermal & solar for heat/AC & electricity, closed cell spray foam insulation. And don't go with the cheesy looking 2 1/2" door/window trim or hollow core doors.
Ummm, you might want to tell them your plan and give them 10 days to fix & fess up. And make sure your notice to them is sent to the boss, not the sysadmin who screwed up and has no stake is letting anyone know.
I read a story the premise of which involved a computer that was designed to create/discover new mathematical theorems. At some point there was found to be an issue in some areas of research, and it was ultimately concluded that another similar effort was being made elsewhere in the universe, and the two efforts were at odds. Essentially the math became 'true' instantly/everywhere when it was first proven, but with different starting points/assumptions the two mathematical realms were in conflict. Don't remember the name/author, and I would love to know (assuming anyone recognizes it from my poor description) to reread and recommend.
Of course it is drafting. It relies on mitigating the detrimental vortex effects associated with moving object terminations in a fluid environment by spreading the wasted energy over a longer object. Same as the efficiencies of longer boats in water, and longer props, whether on planes or windmills. No different in concept.
Actually, in most examples of drafting, the benefit extends to the leader as well, reducing the tail drag associated with a solo player. As I recall, the benefit generally increases as you add cars to the train as the lead drag and tail drag are spread over more units.

If we don't leave, we will surely all die here.

Screw 'em
Perhaps we should start a Super Pac...
Perfect position for trying out various "Hello world" options

Depends on the diameter and the rate of rotation.

Fortunately for you, there is ongoing work underway on a prosthetic sense of humor.
It may be worse than that. The manufacturer may own the rights to any device or system into which it is installed. This guy is screwed!

I'd say it is 80% certain that he does not, with 2 sigma confidence
Mine does :)

that would be - 'in' letting anyone know.- My bad

Thank you!
Difference Engine sucked at every possible level.

Don't be silly, there are no clouds on the moon.

They are the backbone of the Republican Party! (insert comments about lack of spine, segmented bodies, etc. here)
