Look at Coned's official report on Hurricane Sandy. It wasn't a transformer that exploded at East 13th st, rather flood water infiltrated and disabled the protective relaying for the substation. A piece of debri hit exposed busbar, and instead of the fault being isolated to just that section of busbar (as it normally would be by functional protective relaying, it persisted until it was cleared by remote circuit breakers in turn removing all transmission sources (supplies) to East 13th st and in turn all load it fed. Yes I know the media called it a transformer explosion- but they do that with every electrical event regardless of what it really is.

Its interesting that you mention electric trains, in NYC trains are in big trouble when it comes to hurricanes because first both train stations are located underground which is bad for hurricanes because obvious reasons, second is that the LIRR trains use third rail as means of providing the train with electricity, and unlike catenary which is above the train third rail is at rail height which makes it very vulnerable to any kind of flooding (even a small puddle of water in the tracks, do you know how these issues are supposed to be solved?

Could you do a video on the top cities that you think would benefit from space travel (if it becomes common) and how those cities would change? Something similar to your video on Chicago's geography advantage when you talked about how Chicago's location, natural resources, and railroads caused it to become a dominant city. Instead of looking at history to see how Chicago became a powerful city, you could look at what advantages different cities have now and guess if they could be good places for space travel and how it would change them.

This was a bit biased against nuclear technologies. Wind and solar will never be able to make up our base load. In order to fight climate change, we need nuclear power. It is true that existing nuclear plants require vast amounts of water. But that technology was originally developed in the 40s and 50s for submarines. There are much better and more modern nuclear technologies which we must spread knowledge of. Safe nuclear technologies such as molten salt reactors exist and are hands down our best hope for our future power needs.

Why do cities in the US have their power cables running above ground, rather than underground. As a Brit who visited America, this confused me as all our infrastructure has to be buried by law. The only cables you may see above ground is in older parts of the city for street lighting, but that's becoming rarer as the sodium lights are being replaced with LED.

I think the output from renewable sources is very low so that would not be such a great option for that massive supply. To cope with that definitely the power stations should be designed by taking into account the flooding damages. Maybe its time we need new and better ways to design and accommodate the sensitive equipment in power plants.

Many cities in Europe has made underground electrical distribution. maybe a waterproof underground electrical substation somehow? I'd understand however that the two sides of the atlantic has entirely different conditions and challenges (most western european coast being at a higher latitude yet milder seasons and weather.

Great and interesting information. The volume, though was way higher than other videos and sounded tinny. This combined to literally hurt my ears when this video came on. Check your recording software and see if you can balance out the treble and gain or something (not an audiophile. Not sure if I'm using these terms correctly)

Another thing NYC is doing to prepare for the next hurricane is building artificial reefs and break waters out near the mouth of New York Bay. The idea is that these will soak up a lot of the energy in the storm surge and reduce its height. Also helps improve the marine ecosystem as an added bonus.

A park of windmills gives with current technologies 4MWh per sq kilometer. In order to replace all nuclear energy (32636 MWh) with this you need 8159 square kilometers (3150 sq miles. Good luck with that. Even more good luck when there is a week with little wind. You need nuclear.
