Ahh well see here, this checks out you see.
Trump said eat. We export the most bacon, but nobody talks about whether or not we eat much of the stuff.
For all those replying with "well yes, we already knew this".
Yes, but now you have the numbers to back up the conclusions you've already drawn.
Of course food produced from plants will be environmentally better than those made from animals, but now, next time you see someone actually doubting that, you can rebuff them with numbers and science.
Aaaand thats going on my To Listen list.
Kind of hungering for new podcasts right now, and this sounds like one I didn't know I needed.
Thanks!
Well written.
I think an important concept to introduce is Pulse Width Modulation, or PWM for short.
Normal AC Power coming out of wall looks like a sine wave, in that it smoothly cycles between +110/240V and -110/240V. This means that 50% of the time the voltage is positive and 50% of the time the voltage is negative.
PWM usually deals with signals which are either entirely on or off, with no transiton between them. This way, you can vary the amount of "power" delivered by varying how much of the time the signal is on and how much of the time it's off.
Dimmers usually modify the sine way in a way that tries to accomplish the same thing, by chopping up the signal to make the effective "on" time be shorter than 50%.
With non-dimmable LEDs, this messes with the AC to DC circuitry in the lamp in the way slazer2au says, because the lamp doesn't retain enough power between two on-cycles to stay on.
I'm gonna need a link for this.
I'm having a shitty morning and this sounds like just the thing to cheer me up.
