Survey: 36% Of U.S. Adults “Not Concerned” With Electronics Power Consumption

Adults in the U.S. could use a little more education on economics and physics, it seems. We’re not drawing the connection between power consumed by our electronics and the cost of our electric bills.

A new survey from the Consumer Electronics Association found thirty-six percent of adults in the U.S. are “not concerned” with the amount of power consumed by their gadgets, gear and appliances. Sixty percent of U.S. adults, by contrast, are concerned about the cost of their electric bill.

I’m not sure where the conundrum is supposed to be. 60% vs 36%. Since that adds up to 96%, the numbers are not such that you could conclusively say that there are people who are concerned about their electric bill and yet not concerned with the amount of power their gadgets draw. I would not be surprised if such people existed, mind you, but this survey does not present any evidence of irrationality in that regard.

HOWTO make a Joule Thief and get all the power you’ve paid for

This wee beastie is a Joule Thief, a device whose sole purpose in life is to exhaust the power remaining in batteries that are too weak to do anything else. Simply build these and affix them to your “dead” batteries and thrill to the spectacle of the power you’ve paid for being available to you, right down to the last dribble.

Then go out on the porch, shake your fist, and tell those damn electrons to get off your lawn. If you want to skip the curmudgeonly comment, you can go straight to the instructable.

(I use rechargeables, so I have no need of an electron-marrow-sucking device)
