House Wiring: Looking At Light Switches
02 July 2008
A light switch is a light switch, right? You just flick it and the light comes on . . .

A Look At Crash Test Dummies
30 June 2008
Ever seen those video clips of car crash tests where the dummies are thrown about like rag dolls? The dummies are highly engineered to simulate the effect of crashes on human bodies and they carry lots of instrumentation to record the pain (forces & deflections) they suffer.

But you can in New Zealand!

Enersonic Power Saver
19 May 2008
Since our debunking of the "Electricity saving box" in the November 2007 issue, another device along the
same lines has appeared in Harvey Norman stores.
Called the "Enersonic Power Saver" it claims potential power savings of up to 24%. At $59.00, it is considerably more expensive than the previous device but just like that one, it won't save you a cent on your electricity bills.
