OK. So, I've unplugged all my appliances, turned all the lights off and put the Desire on charge. The candle has burned out and ruined the cake. I'm cold, hungry and bored. The meter hasn't moved, and I'm getting cramps from sitting in the cupboard under the stairs for the past 4 hours. However I will persist for the sake of this experiment.
OR.....
I'll nip over to an electricity cost calculator and work out that it costs 24p a month to run 1 amp for 7 hours a day if leccy costs 15p per kWh.
Anything else you need help with while I'm here? Tying your laces? Telling your arse from you elbow?
