Polarity is a term used in electricity, magnetism and electronic signaling, just to name a few areas. Polarity is defined as, the condition of a body or system in which it has opposing physical properties at different points, especially, magnetic poles or electric charge. In the case of electric current running between two points, … Continue reading What is Polarity?

Unpaired Electrons
An unpaired electron is an electron that occupies an orbital of an atom by itself, rather than as part of an electron pair. Unpaired electrons are relatively uncommon because an entity that carries an unpaired electron is usually rather reactive. A formation of electron pairs is usually energetically favourable, either in the form of a … Continue reading Unpaired Electrons
Electric Charge Demonstration
Everything contains particles which have electrical charges, they can be positive, negative or neutral. Atoms are the basic building blocks of everything in the universe, and are made up of three components, electrons, protons and neutrons. Electrons have a negative electric charge and are usually associated with electricity. Protons have a positive electric charge … Continue reading Electric Charge Demonstration
Lord Kelvin’s Thunderstorm
Lord Kelvin’s Thunderstorm is a type of electrostatic generator invented by British scientist William Thomson, better known as Lord Kelvin, in 1867. Kelvin referred to the device as his water-dropping condenser. The device uses falling drops of water to generate voltage differences by using electrostatic induction, which occurs between interconnected, oppositely charged systems. … Continue reading Lord Kelvin’s Thunderstorm
By 2018, an Expected 50% of all Australian Homes will Convert to Solar Power
A new report claims that new battery technology could make it possible for Australian homes to generate and store solar-powered energy more inexpensively than traditional electricity suppliers by 2018. A report by The Climate Council, a non-government organisation, found that improvements in battery technology may make solar energy cheaper than purchasing it within … Continue reading By 2018, an Expected 50% of all Australian Homes will Convert to Solar Power
Bio-Batteries, A Step Closer to Clean Energy
Researchers from the University of East Anglia (UEA) are a step closer to enhancing the generation of clean energy from bacteria. A recently published report shows how electrons hop across otherwise electrically insulating areas of bacterial proteins, and that the rate of electron transfer is dependent on the orientation and proximity of electrically … Continue reading Bio-Batteries, A Step Closer to Clean Energy
Improving Battery Performance is as Simple as a Day at the Beach
Researchers at the University of California, Riverside Bourns College of Engineering have created a lithium ion battery that outperforms the current industry standard by three times, with the addition of common sand. "This is the holy grail -- a low cost, non-toxic, environmentally friendly way to produce high performance lithium ion battery anodes," … Continue reading Improving Battery Performance is as Simple as a Day at the Beach
Harvest Energy While You Munch Away
Researchers in Canada developed a chin strap that can harvest energy from the movement of your jaw. The researchers are hoping the device can generate enough electricity from eating, chewing and talking to power a number of small devices including hearing aids, electronic hearing protectors and communication devices. The initial results of the device’s … Continue reading Harvest Energy While You Munch Away
New Batteries Versus Discount Brands
There is no question you can save as much as 50% on the cost of batteries for your UPS unit if you choose to go with liquidation, clearance or old batteries. But are you really saving money in the long run? Studies show that if you use new batteries, straight from the supplier, … Continue reading New Batteries Versus Discount Brands
How to Make an Electric Microcontroller Patch
A microcontroller is a small computer on a single integrated circuit containing a processor core, memory and programmable input/output peripherals. Microcontrollers are designed for embedded applications, in comparison to the microprocessors used in personal computers or other general purpose applications. Microcontrollers are used in a wide variety of automatically controlled products and devices. Microcontrollers … Continue reading How to Make an Electric Microcontroller Patch
