      Laser Distance Measurement

      For the past two decades, lasers have been used to measure distance without having to physically touch the area or things being measured. Laser measurement is capable of very precise and quick distance measurements. Lasers have been used in military targeting, criminal investigations, and sports. As research has progressed, the size of laser measuring devices

    • What is a Permeable Membrane?

      What is a Permeable Membrane?

      A membrane is a barrier that prevents entry of materials. Membranes can be permeable, which allows certain materials to go in and out of the barrier based on a variety of factors. Permeable Membrane in Biology In biology, a simple example of a permeable membrane is a cell wall. In both plant and animal cells,

    • What Fuels Are Used in Power Plants?

      What Fuels Are Used in Power Plants?

      There are many different types of power plants. Depending on the type of fuel someone wants to use determines what kind of power plant someone would build. The most powerful power plant is a nuclear power plant, but this is also the most controversial because of events such as Chernobyl and because it is difficult

    • 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

    • Weather Modification Technology

      Weather Modification Technology

      Weather modification refers to willful manipulation of the climate or local weather. Research done in this field goes back to as far as the early 1940s when the US military experimented with cloud seeding to stimulate rain. Today, private corporations have joined the weather modification research effort to protect people, cities and assets from the

    • Liquid Armor

      Liquid Armor

      Liquid armor is a new development in the body armor field. It is a material that makes lightweight, flexible and tough body armors possible. Body Armor Body armor is a protective clothing designed to stop bullets or bomb fragments and shrapnel from penetrating the human body. They are descended from leather or metal armor designed

    • Linear Particle Accelerator

      Linear Particle Accelerator

      A linear particle accelerator is a large device that can speed up electrons, ions, or other particles and slam them into a target in order to release subatomic particles and radiation. Sensors then record these by-products, send their data to a central computer system that creates a digital, 3D image of the particle, and labels

    • How Do Quasars Form?

      How Do Quasars Form?

      Quasars are a phenomena that, to this day, continue to baffle and confuse astronomers. There are different theories. One is that a quasar is formed from a super, massive black hole. Another theory is that a quasar is actually a baby galaxy and is at the earliest stages of development. However, since no one really

    • PIR Sensor

      PIR Sensor

      A PIR (Passive Infrared) sensor detects infrared light that is emitted from objects within its field of view. PIR sensors differ from other infrared sensors because they can only receive infrared waves. Because all objects emit infrared waves (electromagnetic waves that travel with heat), PIR sensors can detect objects that are in front of them.

    • What is an Ultrasonic Pest Repeller?

      What is an Ultrasonic Pest Repeller?

      An Ultrasonic Pest Repeller is an electronic device that uses ultrasonic sound waves to repel insects, rodents, and other pests. Though humans are incapable of hearing these sounds, many animals, insects, and rodents can. There is much debate concerning the ultrasonic pest repeller’s ability to actually get rid of pests. While some people claim that
