Understanding Ponyo’s Puff-Puff Boat Mechanism

I really like the films of Hayao Miyazaki. Since we just visited Japan, we are re-watching his films (on Netflix).

In the film, after a flood, Sosuke and Ponyo go in a special little steamboat powered by a candle in search of Lisa, Sosuke’s mother. This time, the propulsion of this little boat caught my eye. I googled it, and it turns out to be a puff-puff boat (or pop-pop boot in Dutch).

I didn’t understand how this mechanism worked, but of course, you can always find someone who can explain it clearly. The remarkable dynamic balance that is created by heated in a boiler, pushed out, and sucked back in due to the underpressure that is created.

PS. I found the first link died. Here is (an even more extensive) description.

Nassim Taleb and optimizing work

I love crafts, tinkering, crafting, and doing things myself. Not only is it cheaper, but you also learn a lot more and have more fun doing it.

Anything you do to optimize your work, cut some corners, or squeeze more “efficiency” out of it (and out of your life) will eventually make you dislike it.

I make one exception: tax returns. I have always done that myself, but with a company, I couldn’t do it anymore. For some things, you need an expert, like the tax return of your small business.

And sewer repair.
