I didn't really think that any of what I wrote would be taken seriously to the point of needing a retort. I mentioned blade servers and knew rack unit measurements which as context clues would have suggested I was familiar with actual data center equipment.
And yet most homes and offices are full of them. Laptop batteries don't usually catch fire. At the colos I am familiar with (which have pretty strict rules, generally), you can have equipment with batteries as long as you regularly inspect them.
They typically have their own UPS in another room and multiple power lanes. And it’s going to be much more reliable than a laptop battery.
