Dishwasher?

Our good friend, the Dishwasher?
Many people around the world will stop using their dishwashers when there is a water shortage. I would rather not use the cooker, using the BBQ instead.

Dishwasher facts.
It was invented by a lady named Josephine Garis Cochrane (1893) who was so fed up with her servants breaking her prized crockery!

Testing times?
In an experiment in Bonn Germany the diswasher was matched against 75 human dishwashers from nine countries. The results were conclusive.
Humans used 15 – 345 Litres of water, 2.4Kw of Electricity.
Dishwasher used 12 - 20 Litres (on Economy setting), 1 Kw of Electricity.
Only 15% of the items washed by humans matched the cleanliness of the Dishwasher.

Save Your Money
Tip to save power with dishwashers is to use the air drying setting if you have one, or to open the door and not use the drying element.
The drying element in Dishwashers uses the most electricity.

Thanks for another interesting (and useful) piece of information Mark. I see that your source is the very learned Australian Dr Karl Kruszelnicki! Some families that I know also save on power by not washing up.

Mark, love the post but I think you need to use headings a little more - just makes it more eye catching, especially in a blog reader.
