Locally, there was a radio station running PSAs to tell people to unplug their cell phone chargers "To save the environment".
I was very tempted to call in with some envelope calculations on the energy expended to send out the PSAs vs the energy saved. It's not easy being green, but it's easy to LOOK green. ________________________________________ From: [email protected] [[email protected]] On Behalf Of Brooke Clarke [[email protected]] Sent: Monday, June 27, 2011 1:12 PM To: [email protected]; Discussion of precise time and frequency measurement Subject: Re: [time-nuts] Transformers Hi: For small (say under 5 Watt) loads the old wall wart has bit the dust (at least in California) because they waste power. The new wall warts don't use mains frequency transformers, but rather transformers running is kHz frequencies. You can tell because they are much smaller than the old ones and much lighter as well as working on any mains voltage and current in the world.
