Power is energy per unit of time. Energy is power over a period of time. A lightning strike is about 1 GJ of energy. But it happens in a split second, so the power is far higher, say 100 GW. That is the output of 100 nuclear power plants. But only for 0.01 seconds.
TNT is even more extreme. It can detonate in microseconds, so release its energy in a fraction of a millisecond. 1 kg contains about 4 MJ of energy, released in about 10 microseconds, a power of about 300 GW. That is about as much power as all of the USA combined needs.
- Comment on Have you know???. 2 days ago:
That’s power, not energy.
- Comment on Have you know???. 2 days ago:
Kilowatt is not a unit of energy.

That format has been used like this for a long time.
- Comment on Do farts at least nominally increase the overall temperature of the room in which they are extruded? 2 days ago:
The edge cases, so mixing very polar with very nonpolar gases has deviations in enthalpy. Very tiny, but they exist.
Mixing inert species like nitrogen, CH4 or oxygen (anything human, fart or air related) does not result in a change in enthalpy. All it does is increase entropy. They are essentially ideal gases under these conditions, nothing happens.
Which Wikipedia article? Please name them so they can be corrected.
Heat does not get absorbed. Semantics or not, these words have well defined meanings.
- Comment on Do farts at least nominally increase the overall temperature of the room in which they are extruded? 2 days ago:
No. Gas in gas can not be a solution. The solvent must be a solid or liquid.
- Comment on Do farts at least nominally increase the overall temperature of the room in which they are extruded? 2 days ago:
Each molecule is on its own. There is nothing to dissolve. No bonds to break.
- Comment on Do farts at least nominally increase the overall temperature of the room in which they are extruded? 3 days ago:
This is an interesting detail, but there is akready so much written here, and lots wrong, that giving an answer that really helps would be way too much effort.
But in real world terms it really does not matter at all and you would have a very hard time even measuring any sort of effect.
- Comment on Do farts at least nominally increase the overall temperature of the room in which they are extruded? 3 days ago:
This is not happening here. There is no solution, everything is a gas.
- Comment on Do farts at least nominally increase the overall temperature of the room in which they are extruded? 3 days ago:
Still not a solution.

Crazy that we keep trading etc. with a country that is hostile like that.

Ah thank you, why did I not think of that easy solution? I always power it via my hamster at home.
- Comment on Ideal car 5 days ago:
I have never seen an equal sign on any licence plate or road sign. What is your point? I already mentioned that too.
- Comment on Ideal car 5 days ago:
Would be even better if the capitalization was correct. Always bugs me when people capitalize units wrong, but in this case it might have been mandatory.
- Comment on Here’s What Happened When I Made My College Students Put Away Their Phones 5 days ago:
I exclusively wrote everything down with a pen, since I was not going to bring a laptop everywhere and somehow get it to stay powered for so many hours. Not to mention that it would have been terrible to draw schematics etc.
The best were those courses where you could prepare a “cheat sheet”, so then I go over everything and put key information and formulas into a word document. So I go over my notes, then have to filter them and then write the key things again. Maximum retention, as I can tell you 10 years later.

Did you give it some days to finish processing in the background? That eats battery until it is done.

100 billion losses just from some 200 million pirates? What…? That’s 50 $ per person per month. Enough to pay the 3 most expensive options or Apple, Disney, Netflix basic, CBS and YouTube combined. All year round. Fuck off with such made up numbers.

That would be a good start, no question.

The answers are both the same, people that want more power.
- Comment on Any US Military Action in Mexico Unacceptable: Foreign Ministry 2 weeks ago:
As much as I hate what the USA do, but helping people get rid of those cartels is something I would appreciate a lot. And I highly doubt their government is able to deal with that problem on their own, they are too powerful and murder any opposition. The same way North Korea is stuck in the middle of the 20th century.
- Comment on Tesla withheld data, lied, and misdirected police and plaintiffs to avoid blame in Autopilot crash 3 weeks ago:
Mate, a 1 TB micro SD costs less than 100 $. How much does a high bandwidth high/no data limit 5G connection cost and how long would that need to actually transmit that much?
What sensor data is there even supposed to be? Even at 1 millisecond resolution we are talking about megabytes.
- Comment on Tesla withheld data, lied, and misdirected police and plaintiffs to avoid blame in Autopilot crash 3 weeks ago:
If they can transmit it, it is not a lot. It is that simple.
