I don't understand that reading of it. > Its spherical walls were built to deflect 150-mph winds that would level most conventionally designed homes. Unless they got the numbers wrong, the writer is simply being imprecise, probably treating "gale" and "hurricane" as synonyms. Good thing they didn't use "zephyr" too. Meanwhile, the real point of it is not that the homes' engineering failed, but rather that withstanding 150-mph isn't enough. Now you need to build for at least 200.
