What is the possible area a Zamboni can do? How many would be needed to cover the whole surface? [[User:SDSpivey|SDSpivey]] ([[User talk:SDSpivey|talk]]) 02:56, 18 April 2026 (UTC)
:Europa has a surface area of about 3.061×10^7 km^2. A zamboni seems to cover about a 1.2 m^2 area (about 0.6m by 2m) at any given time. So if you simply cover all of Europa in zambonis (only like 3 trillion) and then drive them all forward their own length at the same time without crashing them into each other. So probably less than 3 trillion would be my guess (Also probably more than 2).
:They probably do like 8L/h and cover about 8000 m^2/h. So if they had 30 litre tanks, you would need 1 billion zambonis (0.03 km^2 each), and they would take 4 hours. Or for 1 month : 5 million Zambonis, refueled 200 times each (30 billion litres propane total). For constant resurfacing, like a normal ice rink (~10 times a day), you would need 2 billion zambonis running constantly (90 terawatts).

:: I think for the complete covering option you'd need at least one zamboni to rotate in place, as a consequence of the hairy ball theorem. [[Special:Contributions/137.25.230.78|137.25.230.78]] 15:58, 18 April 2026 (UTC) 

Is Randall confusing the Jupiter Icy Moons Orbiter and Jupiter Icy Moons Explorer here? [https://en.wikipedia.org/wiki/Jupiter_Icy_Moons_Explorer wikipedia link]
Also this feels like it is probably a reference to [https://en.wikipedia.org/wiki/17776 17776], what with all of its topics and the recent rise in interest in that work. [[User:SkiesShaper|SkiesShaper]] ([[User talk:SkiesShaper|talk]]) 03:47, 18 April 2026 (UTC)

The hovertext leaves ambiguity between the transitive and intransitive meanings of "resurface", leading to me imagining a Zamboni Voyager mission profile that involves cracking through the ice layer just to make moonfall and then climbing out of the ocean somehow.

: The Zamboni Voyager also has a suspiciously sharp part on the bottom side, which could conceivably support this view. Resurfacing would probaly involve 3-D manoeuvres not necessarily allowed in 2-D Hockey on Earth. But the Federation MUST EXPAND [[Special:Contributions/2001:861:3F07:A020:A19A:2BA:622D:DCA4|2001:861:3F07:A020:A19A:2BA:622D:DCA4]] 23:09, 18 April 2026 (UTC)
:: That's just a standard(-looking) Zamboni machine sat on top of a booster/lander chasis that's currently firing its main rocket... [[Special:Contributions/81.179.199.253|81.179.199.253]] 23:30, 18 April 2026 (UTC)
::: That's what they want you to think. "170 to 2 due to burrowing" was just not acceptable for the Confederacy's teams managers. [[Special:Contributions/2001:861:3F07:A020:A19A:2BA:622D:DCA4|2001:861:3F07:A020:A19A:2BA:622D:DCA4]] 23:34, 18 April 2026 (UTC)

Is this a joke about the NHL expanding to Europe? --[[User:Coconut Galaxy|Coconut Galaxy]] ([[User talk:Coconut Galaxy|talk]]) 06:37, 20 April 2026 (UTC)
: That's how I took it, as a joke on the silly Americans confusing Europa with Europe. (As a silly American, I get to say this) [[Special:Contributions/130.76.187.47|130.76.187.47]] 13:44, 20 April 2026 (UTC)
