      Long Distance Wireless Power Transmission

      Simple wireless power transmission works because of the principles of magnetic resonance and magnetic induction. This power transmission system relies on two coils in range with each other and resonating at the same frequency. The coils need to be in range because the magnetic field of the source must be strong enough for the receiving

    • Long Range Acoustic Device

      Long Range Acoustic Device

      The LRAD or the long range acoustic device that has been developed by American Technology Corporation is capable of emitting a maximum of 151Db sound within 30 degrees of where the device is pointing. This device can be used as a combatant deterrent weapon or crowd-control device by emitting sounds that are painful to the

    • Potassium Chlorate

      Potassium Chlorate

      Potassium chlorate is a chemical compound that contains chlorine, oxygen, and potassium. In its pure form, it is white and crystalline in appearance. It is the most common chlorate used in industry, school, research, and commercial labs. Potassium chlorate is commonly used: to prepare oxygen, in safety matches, as an oxidizing agent, in fireworks and

    • Air Exchangers

      Air Exchangers

      An air exchanger is a device that transfers stale air from inside a home to outside, and fresh air from outside to the inside. Air exchangers are often large and built directly into a home’s foundation in order to provide maximum fresh air levels at all times. This is important because indoor air is often

    • DNA Fingerprinting

      DNA Fingerprinting

      DNA fingerprinting is the process of taking a cell sample from a person and analyzing it. This technique involves analyses of less than 0.1% of human DNA (which is different for each person). Though small, this 0.1% of DNA is enough to distinguish one individual from another and can be used to determine maternity/ paternity

    • What is Photolithography?

      What is Photolithography?

      Photolithography is the process of making integrated circuits through optical erosion. Rather than directly cutting into an integrated circuit, photolithography is used due to its ability to perform more precise incisions. Photolithography is a highly complex technique and requires both an extremely clean substrate surface and ideal temperature conditions. It can only be used to

    • Perigee

      Perigee

      Perigee is a term used to describe the closest point at which an object orbits the Earth or another object in space. When an object is at its perigee, it travels faster than it does at any other point in its orbit because it is under the influence of the strongest gravitational force that its

    • What Causes Optical Illusions?

      What Causes Optical Illusions?

      In simple terms, an optical illusion is caused by the structure of both the eye and brain and how they work together. Because of the anatomical make up of the eye and the complexity of the way images of transmitted from the eye to the brain, optical illusions are not as rare as one might

    • Vehicle Platooning

      Vehicle Platooning

      Vehicle platooning is one of the innovations in the automotive industry that aim to improve the safety, efficiency, mileage, and time of travel of vehicles while relieving traffic congestion, decreasing pollution and reducing stress for passengers. One of the recent demonstrations of this technology was during the PATH program done in California by 8 Buicks

    • Potassium Benzoate

      Potassium Benzoate

      Potassium benzoate is the potassium salt of benzoic acid. Benzoic acids are weak acids that are used as food preservatives. Potassium benzoate is also commonly used for preserving food. It is primarily used to inhibit mold and bacteria growth. This allows the product that potassium benzoate preserves to last longer on the shelf, thereby increasing
