dasman’s World

I have to admit that I never saw the original Captain Planet cartoon series – I gather it was about a superhero with a real environmental streak. Well, a friend put me onto a little video on the Net that has a whole new interpretation…

I should warn that its probably not for little kiddies – its only claymation animation, but some of the language is rather… earthy (pardon the pun)!

Enjoy!

I make it a habit to do a quick google around the net around once a week or so to see if there are any rumours about the next generation Prius. After all, its been 2 years since I bought mine – there has to be something in the works, right?

Well, stumbled across something at digg.com today on the first whispers about the next model. I’ve googled a little further, and this URL has a decent summary:

http://www.greenhybrid.com/discuss/2008-prius-lithium-ion-and-94-mpg-us.6729.html

To spoil the surprise, they’re talking about a lithium battery (instead of NiMH), fuel economy roughly twice as good (which is pretty mind-blowing itself), and shaving a second or so of the 0-100km/h figure. Nice……

Only downside? The net gossip is talking about 2008 as a release date – and thats for the UK/US! Past experience has Oz getting their models another year after that. Sniff….

As of yesterday, I’m now the proud new owner of a centameter – a handy little display that shows you how many kilowatts of power your household is using at any instant. Here’s a picture:

As you can see by the mouse sitting next to it, it’s a reasonably small, neat unit. And, a little less obviously – its wireless! This is a great feature! It means (as well as being able to mount it semi-permanently somewhere), you can also carry it around as you check out your house’s (and its appliances) energy characteristics.

The way it works is with a neat white sensor unit installed either at your switch box, or meter. A sensor clicks on to the outside of the wire, and the sensor unit transmits this data wirelessly. The transmission is powered by a few AA (or AAA, I can’t remember) batteries which apparently last a year. The display unit picks up these signals and displays it.

You can configure the display to update every 6 seconds or 1 minute, and it can show current kilowatt consumption, current amount of CO2 production due to your energy consumption, and cents/hour. Additionally, the unit shows you the current temperature and humidity.

All up, it cost me around $200 to have installed. This included an electrician to come out and do the install – this is required simply because a licensed electrician is required whenever you’re dealing with switch boxes and metres.

And, after a day of use, I love it! Its better than TV – in fact, energy wise its a lot better; I’ve discovered that turning my TV on uses an extra 150 – 200 watts! But in all seriousness, some of the discoveries you make can be quite eye-opening:

• When my house is pretty much “off”, it uses around 250 watts – thats TV’s, etc on standby, the usual collection of digital clocks and (most significantly) 3 PCS that are on 24×7. These PCs were all selected as being low power consumption models
• When I turn on my “actual” work PC, consumption jumps by another 150 watts or so. This PC is a standard PC – not a low power model and that shows!
• The biggest impact is my (electric) hot water heater – when its running, around 3.6 kilowatts are drawn! I was quite surprised to see this, and was able to confirm it by turning the hot water off at the mains, and seeing the drop immediately on my centameter. Obviously, the hot water unit doesn’t run that often. Thankfully.
• And from the biggest to the smallest. I have a power board full of those little black plugs. You know the ones – phone chargers, camera charges, laptop. Nothing’s being used – they just sit there waiting for me to plug something in. Now, I’d heard that these things waste power when not being used – turns out they were collectively going through 30 watts. Or $26 a year. They’re all unplugged now!

End of the day, I can’t rate this highly enough. If you are even the faintest shade of green, this thing is a must have. But even if environmental issues bore you to death, being able to see how much your house is costing you in electricity bills is fantastic.
