Drying the Mediterranean Sea is surely a bad idea, but I wonder why nobody ever built hydroelectric generators into the Strait of Gibraltar. There is a huge steady flow of surface water from the Atlantic into the Mediterranean (1 million cubic meters per second), and almost as much flows back into the Atlantic in deeper layers. Why not tap into these streams to generate electricity?

This reminds me of the CargoLifter https://en.wikipedia.org/wiki/CargoLifter

They wanted to create a fleet of LTA vessels some 20 years ago, but never made it beyond a reduced-scale prototype and eventually had to file bancruptcy after using up all their investors' money.

The only thing that remains is an impressively huge hangar in the middle of nowhere near Berlin, which is used as an indoor resort today.

I wonder how hydrogen peroxide (a strong oxidant) can reverse the yellowing of plastics, if the yellowing is the result of oxidation. I'm not a chemist, but this doesn't seem to make sense.

I heard a similar story (a joke from the communist era) around 1995 from a Czech colleague. It was about an artist whose works were never censored.

When the other artists asked him how he did it, he replied: "I always add a little white dog in my paintings. When the censor asks 'What is this dog?' I quickly remove it and he's satisfied."
