There was a bit too much separation going on, Shirley?

Yes, but now they want to test the cooler, which means they need a heater to heat the air for the cooler to cool. Keep in mind that the cooler not only cools the hot air going in, it also heats the cool stuff being used to cool the hot air. I'm saying link the cooler and heater together so the hot stuff coming out of the cooler heats the heater to heat the air to be cooled in the cooler. Is that cool?
By the above definition, the whole orbit of the planet must be cleared and therefore none of Mercury, Venus or Earth are planets, as their orbits are not cleared."
There's more to the definition, size matters: "there are no other bodies of comparable size other than its natural satellites or those otherwise under its gravitational influence." Therefore dust & small rocks don't count and don't have to be cleared. By current terminology, Mercury, Venus and Earth are planets in dusty orbits.
If I aim my blowtorch at an aluminium can until it deforms, have I made a robot? According to these guys I have! But no I haven't.
On the other hand the precision fabrication of nano-things is impressive and there's a good chance the technique will prove useful someday (even if not in actual robots).
“The other issue is: Where is the fuel coming from? If it's coming from Earth, what are you saving by sending the fuel & vehicle up separately?”
If you send fuel and ship up separately you aren’t saving anything per se. But you are sending up two loads instead of one, so now you have twice as much up there and you can now go further. How about sending three loads of fuel up? Or ten? The sky isn’t the limit!
More like one thousandth of a light year, but even so I see what you are trying to say.
The thing is, we can see lots of large objects, we can see evidence of lots of large & medium object impacts, but the evidence of small object impacts is missing: not many small craters. So, not many small objects out there, relatively speaking.
I remember flying over a mountain of the stuff heaped next to the Ranger mine in Kakadu. It's all been dug out now and the mine is closed. People are wondering what to do with this huge hole in the ground which used to contain radioactive ore. Nobody wants to put radioactive waste at the bottom but it's got to go somewhere and this would be as good a place as any, wouldn't it?
It's amazing what you can fit in a briefcase these days, e.g.
- a Mars probe
- a nuclear weapon
- two bags of grass, seventy-five pellets of mescaline, five sheets of high powered blotter acid, a salt shaker half full of cocaine, and a whole galaxy of multi-colored uppers, downers, screamers, laughers...
Ethanol and also hops. Hops are naturally antibacterial. If your beer is at least 2% ABV and also at least 20 IBU (International Bittering Units, a measure of isomerised alpha acids derived from hops) your beer is unlikely to spoil.
A long time ago in a monastery far far away (or possibly just down the road depending where you live) monks brewed ale (not beer in those days) for the local community. They did mash the grain more than once as mentioned above, they kept the very strongest ale for themselves, the normal strength was for evening consumption by adults, and the last runnings made small beer for kids and mornings.
Some modern breweries still get two runnings from one batch of grain: this is called parti-gyle brewing. Fullers is a good example of a brewery who use this method. The first runnings (strongest) goes into one kettle to be boiled, the second runnings (weakest) goes into a second kettle. They then blend different proportions of strong & weak to get different strength beers as desired. If the two kettles are boiled with different varieties of hops then the resulting stronger and less strong beers can taste very different, even though they were made with the same grain.
p.s. Brewing is my day job.
My first thought was why not build one around the equator and be done with it. But... oceans are tricky and so are plate tectonics. OTOH there are no oceans on the moon (misleading Latin names notwithstanding) and it is geologically stable.
But only a lunatic would suggest that.
