How efficiently (or inefficiently) would your household function without batteries?For me, the first thing which came to mind was that my camera wouldn't work without batteries. So if I had no batteries in the house, I'd have to go back to the "old-fashioned" film method (some film cameras don't need batteries). But this is more inconvenient than it would seem. If I wanted to change to film, here are some of the costs that would be involved:
- I'd have to buy a new SLR. Cost: AUD$700+
- Since September (four months ago), I've taken approximately 9,000 photos. If I were to take these on film, I would need about 375 rolls of film. These would cost over AUD$1,800.
- To develop the 375 rolls of film would cost about AUD$6,000
Apart from cameras, there are quite a few other things in the house that use batteries. For example:
- T.V. remote controls - These devices are very handy, and without them we would all be forced to perform the laborious chore of actually standing up and walking across the room whenever we wanted to turn up the volume.
- Cordless (or mobile) telephone - Have you ever noticed that when you're talking on a cordless phone you tend to start walking around the room? Without them, you'd have to stay standing beside the phone the whole time - until you need to get the pencil and paper that aren't there.
- Computer - Hang on, doesn't the computer run without batteries? Yes, as long as it is turned on. But when you turn off your computer, a small battery inside of the case takes care of the time, making sure that when you next start up, it knows what day and hour it is. Without batteries, we'd have to reset the computer's time - and the time of every clock in the house - all day.
