Except for farmers humanity has gone quite a long time without them

Edit to clear up confusion about the wording: I meant that we need farmers, the rest not so much

I used to think this was true while working for a B2B company as a graphic designer. Everything just seemed pointless like I wasn’t contributing anything meaningful to the world.

You could say similar things about company doctors that just try to get people back to work without caring for their wellbeing. Companies do not necessarily bring out the best possible use of skills.

It's a great book

my 50 watt lightbulb will run for an absurd number of years when hooked up to a nuclear generator and will be completely vaporized by the nuclear bomb.

That is true whether you express the energy as kWh or MJ.

Also keep in mind your average person likely doesn’t remember their physics classes and how joules, time, and watts all relate to each other

It's becoming clear to me that you don't either. KW is not the same as kWh, the latter does not have a time component anymore despite the name. Watt is the amount of joules per second. kWh is the amount of energy spend it you use 1KW for an hour regardless of the time that amount of energy is spend in similar to how a lightyear is the distance that light travels in a year regardless of how long you take to travel that far.

Uranium has 2x10¹³ joules of energy stored. You can use all that energy at once in a bomb and explode a city in a second, a lot of Work done very quickly, ooooor you could put it into a reactor and power a city and do a lot of Work during a much longer time period.

And the amount of kWh provided is the same in either case. So using kWh gives you no relevant information about how the device uses that energy during a period of time.

Did you know that with Salmonella you can lose all of your weight?

My point is that kWh is the same. It doesn't say anything about time. 1 kWh is 3.6 MJ. There is no difference except the factor 3.6.

It does spark more though

I don't see it like that. The ball is chained to the leg. What choice do you feel it suggests?
