I bought a plug-in pest repellent. It claims to only cost pennies a month to use. I was wondering if anyone knew how to calculate it. The provider we use scottish power and the device claims to be 7.5watts , but doesn't have any amp/voltage figures on it.
It'll be on constantly, how much will it cost?
Also, does anyone know if these things are any good? It's a Viatek dual technology one that uses electromagnetic and ultrasonic technology

I know that 1 tube of caulking is 10.3 oz. I also know that when you push a bead out that is 1/4" x 1/4" the 10.3 oz. tube will lay down 24.4 linear feet of caulking. I need to put this in a formula to calculate different beads of caulking. Bead height will always match width. Thanks.

First of all, I'm not saying I believe in it.
I just want your opinion.

Here's what they claim:
There are intelligent beings who reside on mars but are only watching over us and not making their presense widely known.
They're responsible for the UFO sightings.
They're responsible for the formation of pyramids on our planet.
They've built pyramids on mars and other geometrical objects that have been photographed and compared to other structures.

If you wanna know more... go to Youtube.com and SEARCH
Nasa/Mars Coverup.
It's atleast interestingly bizarre enough to enjoy whether you believe in it or not.
