If you've never heard of the Indian Ocean, you probably don't have much interest in the world as a whole

These videos are pretty stupid. Geography is largely irrelevant to most people's lives and therefore qualifies as trivia. It's like asking someone how many bytes are in a kilobyte or how many bits are in a byte except that's actually relevant since knowing those things will help you see past the marketing BS of ISPs and hard drive makers.

Different people know different things and someone isn't automatically "stupid" because they don't know random facts that serve no purpose in their occupations or daily lives.

the percentage rating shown when not logged in seems largely pointless, since practically every video has a rating of 100%, downvotes being rare on videosift.
if every video except a handfull is rated 100%, you might as well not show the rating, it's sort of useless information.

Munich at 2:50, and of course this video has been colorized in modern times, probably in the last few years. There is a well known BW version that's been around for a while...

Assume A=1m^2 of t=5cm thick glass, thermal conductivity k=1W/(m*K), glass to be kept at a constant 5°C with an average ambient temperature (averaged over the whole winter season day and night) of 0°C => temperature difference DT=5°C (also no salt to help, original promo video claimed that as an advantage of these things), you'll need roughly

A*k*DT/t = 100W of constant power (day and night for the entire winter!) to keep the tiles at 5C (i.e. 100W/m^2 of tile).

There's NO WAY you'll produce that much power per square meter on average (day and night!) in the northern winter (!), meaning the tiles would soon be covered by that thin hard layer of compacted snow that you get, rendering them basically worthless in the winter.

There's also a negative feedback mechanism: if you don't produce enough power to melt all the snow or ice, some of the area gets blocked, which reduces power output even further.

Where I lived, in northern MI, these tiles would be useless for about 9 months of the year

Apparently it takes a shitload of energy to melt ice, but how much energy does it take to prevent ice from forming?
