If 70 m is the diameter, not radius, that area is a factor of 4 too high. Should be more like ~3850 m^2. Still physically impossible at that size but it does make the required size a bit more tenable.

To be clear, the heading of that column is Diameter.

As a sanity check, the video says the area of the dish is approximately one acre which would be ~4,046m2 and a 35m radius disk is ~3,850 m^2.


For those using freedom units that is about 200ft diameter, or about 31,000 square feet.

This works out to roughly 0.7 acres.


Funny enough the foot was restandardized to .3048m in 1959. So it is a metric-derived unit. Before that it was a feifdom unit, set by kings.


Was a tongue-in-check turn-of-phrase. This place is wound tight apparently.


Your tangential remark is ok but anyone else's is wound up too tight. OK.


I was trying to frame the numbers for people who don’t have an engineering background. My mistake.


And they provided an interesting tidbit of information about some of the units mentioned. I didn’t read it as anything negative towards your comment at all. Both your’s and their’s added to the conversation.


Oh, now you're just trolling the Apostrophe Nazis! ;)


And it made sense for you to then call it “freedom units“ why, of all possibilities?


Eh, it's a pretty common tongue-in-cheek way to refer to America's love of a slightly old fashioned system. I wouldn't read much into it.


Words matter.


At least half of the world has been violently invaded by this so-called “freedom“ and will take offense by this framing. Rightly so. Freedom by force is simply violence, with the additional violence of deliberate newspeak. Anyone repeating this joins the perpetrators, consciously or out of ignorance, and anyone not speaking out against it supports them by inaction and avoidance of their own responsibility and power.


Hey just having fun. Transatlantic banter and fun facts.

I had to look it up to check: my mental model was that a foot is some king's foot but there is more of a storied history.


Usually this joke flies but apparently, after the last election, people seem to take it seriously.
