In this episode we collected a whole bunch of interesting electronic devices that will help you with safety and security around your home.Many people worry about the health effects of electromagnetic fields caused by wiring and appliances. A gauss meter is what scientists use to measure the s...
That is an interesting idea. Put the heater on the ceiling as part of a ceiling fan which assures that all that extra heat up there gets circulated all around the room.
Room light, ceiling fan for summer cooling and heating unit for winter heating all in one unit. Add to that a remote control za...
The field of energy efficient heating systems is advancing rapidly and constantly and I cannot evaluate all the new products here. Remember that it usually takes a company a couple of years to work the bugs out of new products. And some companies try so hard just for novelty that... for example i...

Patio doors are actually very large windows and even when the weather-stripping and caulking is in good shape, they can create cold drafts in a room simply because there is so much cold glass that the air at the top begins to cool off, slides down along the glass getting cooler and cooler as it g...
All electrical currents give off electromagnetic radiation when there is any change in the current flow, which means that our standard AC current is giving it off all the time. (DC current only creates an electromagnetic field when it goes on or off or changes magnitude.) Transformers tend to giv...
