(There are only 2 technical changes to this blog for 22-Apr-2008, but I thought it was worth a re-post given the date)
3:55 filmed power meter “before” self-imposed blackout
8 seconds of power meter – note the radial sweep
3:59 shutdown unix server, vonage dongle, voip wireless phone base. Skipped downstairs hub-dongle buried.
4:02 microwave, coffee machine-skipped stove, fridge and wired phone base. Dongle for kitchen stereo. Unplugged DeWalt cordless radio charger and B&D FireStorm charger.
4:07 Unplugged tv, dvds and laptop charger.
4:27 filmed power meter “after” blackout
About 15 seconds – imperceptible rotation.
Hot water heater is still on. Dishes? (later)
During the day, I charged up my solar powered lantern. I got it for use at camp, but tonight seemed like the right time to light it up.
Dinner was a can of soup with extras, prepared using my solid fuel powered backpack stove.
Access To Tools
For more information on this stove, which uses twigs, sticks or charcoal lumps from other peoples’ fires 😉 see:
It uses a AA battery for a bellows effect; I’m using a NiMH rechargeable battery but don’t have a solar charger (yet).
There’s a review by Stewart Brand (yes, that Stewart Brand) here:
with a shorter version here:
A short quote from Brand’s review: “We’ll all want one when the economy collapses completely and we have to live homeless.”
I brought the lights back up around 9:30, switched on the heat and the background hum of electronic devices.
So, what does this mean to ye SDN reader?
See my prior blogs on measuring energy use and sustainability topics:
- Electric rates – the inexorable surge
- Rented a car lately? Would you like carbon offsets with that?
- My Carbon Footprint at Home
- CSR and Me
Obligatory business return on investment advice:
If you leave your PC on all the time, but only use it 40 hours per week or so, you’re wasting about 3 times as much energy as you are using productively (168-40).
I did not analyze what my trough energy use was when shutting down, but 2 ways of doing this would be to count the meter rotatations per minute to get watt-minutes or fractions of kilowatt hours, or add up all the nominal wattages for all the devices. I think the server had the biggest hit (200 watts maybe?).
