    There’s also fuel cells, where fuel is not burned to create steam to move something, but combined with oxygen in a different way (the end products still being the same) so the electrons shuttled around during this reaction can be utilised as electricity. Think of combustion as oxidation of your fuel, the oxidation meaning that you (among other things) move electrons from the fuel to oxygen. In combustion, unfortunately you can’t access the electrons directly, as they are always stuck in the chemical bonds of the molecules, that’s why we take the detour via heat/mechanical - the steam engine. The fuel cell now separates fuel and oxygen, and thus divides the combustion reaction into two parts that happen at opposite sides of the cell. Those sides are divided by a membrane that does not allow the electrons to transfer across, so they need to take a detour through an electric circuit, in which we can harvest them as electrical power.

    I always found it really fascinating that fuel cells are the only other technology than solar where the electrons we use as electrical power are more or less directly generated as opposed to the detour via a generator. Unfortunately, fuel cells are still a very niche technique.

    He won’t, because he’s rich. The article is so apologetic already, several paragraphs about how bad this poor guy feels. Bonus points for mentioning he’s a father of four (nothing is mentioned about the victim’s family). "I’m not a thug!'. You disregarded other people’s safety and well being for your own benefit, when being called out, you used unreasonable force. That’s a thug to me.






  • This so much. I have a three days a week home Office deal, and I did Not, We, Fr for some time and it sucked. Monday I just could not find a proper start for the workday, which in the end translated to doing more work in the evening. Same on fridays, where I just did not find a proper cut to end the work day. So bad it even went into Saturday mornings. Now I do Tu-Th as home Office days, which works amazingly.





  • It’s completely wild to me that the default for buying a car comes up to a monthly payment, why not pay cash? Save those 800 for three months, buy a beater for 2400. While driving this into the ground, continue saving the 800, even if that beater craps out after six months, you can upgrade to a 4800 not-so-crappy beater, rinse and repeat, and at some point you saved up the 48000 to get that new car. Financing something that depreciates in value quickly and exponentially at anything above the inflation rate is, financially speaking, complete and utter nonsense to me.


  • Put a smile to my face to see so many cats (and dogs) involved.

    When I get up and do my morning business on the toilet, the cat comes and rolls around on the bath mat in front of my ear scratches and cuddles included. Turning on the bidet (yes, hidden flex) is the audible clue that business is concluded, he gets up, wait patiently in the door frame while I start brushing my teeth. I then walk downstairs (while brushing my teeth), cat as added tripping hazard on every step. He again waits patiently while I start the coffee maker, and only when I open the door of the cat food and treats cabinet, he starts being agitated until I put food in the bowl and put it down for him. And then there’s always this glance back, blinking before he digs in, and this very moment is my treasure for the day.
