Interesting ideas/products in March 2007 Popular Science

Hello:

The March 2007 issue of Popular Science had a write up on a couple of interesting products.

First, they mention a Power Cost Monitor. Basically you attach a magnetic monitoring device to your electric meter (no it does not mess with the working of the meter). This device transmits data back to a base unit which among other things tells you in lay terms your current power usage and the cost. Information on this product can be found at http://www.save-electricity.ca.

Second, they highlight a new photo voltaic technology known as Heliotube. In a nutshell, this panel uses thin strips of photo voltaic material located within reflective troughs which focus sunlight onto the strips. Information on these panels can be found at http://www.practicalinstruments.com.

Enjoy!
