Nice Appliances Direct photos

A few nice appliances direct images I found:

Overnight use of high-draw appliances

We’re quite pleased with the new Sears/LG laundry boxes. The dryer has a rare feature, a delay before operating. Learn more about time-of-day metering or see a graph indicating why power should be cheaper at 2am.

Washer: LG WM1333HW seems to need about 0.10 kWh per load.
Dryer: LG DLEV833W.
Both are Energy Star rated and have delay features.

What is a kilowatt hour?

radiation appliances have many uses. this one may destroy an object thousands of miles away, using no projectile, with less cost, danger, or targeting, instantly at the speed of light.
it can also send data into the cosmos, or collect information.

Of course there are many imperfect ways to get the current power data off the TED; here is the imperfect way used for this graph:

date +"%s %F %T " | tr -d \n\r
wget -q -O – wirchy:9090/DashboardData | grep KWNow | tr -d [:alpha:] | tr -d [:blank:] | tr -d \ | tr -d / | tr -d \n\r
echo

Run from cron, direct output to a log, analyze with gnuplot script above.
