Small Horizontal Axis Wind Turbines Leviathan Energy

Small Horizontal Axis Wind Turbines (The technology is in the developmental stage.) This takes the same technology as for underwater turbines and applies it to wind. The main product will be a ten-meter blade diameter horizontal axis turbine with capacity of 50 kilowatt. Other turbines of the same size can only produce around 20 kilowatt. This is an important breakthrough for intermediate size wind turbines as it

Frequently Asked Questions: EMF Meters

The proper orientation of a single axis meter may point the meter at the wire, or straight up and down, or even horizontal, depending on the orientation of the sensor in the meter and the position of the meter relative to the wire. Furthermore, the orientation of a 3-axis meter is irrelevant to the reading, so it could be pointing in virtually any direction and still give a correct reading.

AXIS D2050-VE Network Radar Detector Axis

AXIS D2050-VE detects movement and nothing but movement, 24 hours a day. It’s not sensitive to things that often trigger false alarms. Like moving shadows or light beams, small animals, or insects. With 120-degree horizontal coverage and up to a 50-meter (164 feet) range, it also delivers the angle of movement, and speed of moving objects. Plus, it provides exact positions, allowing you to filter on

AXIS F1025 Sensor Unit Axis Communications

The small AXIS F1025 unit can be installed, for instance, in tight places, in doorways, behind metal sheets or flush-mounted in a wall or ceiling, with only a pin hole visible for the lens. AXIS F1025 comprises an image sensor with 1080p resolution (1920 x 1080 pixels) and a pinhole lens that provides a wide 92° horizontal field of view.

Current meter Wikipedia

A current meter is oceanographic device for flow measurement by mechanical, tilt, acoustical or electrical means. Different reference frames. In physics, one distinguishes different reference frames depending on where the observer is located, this is the basics for the Lagrangian and Eulerian specification of the flow field in fluid dynamics: The observer can be either in the Moving frame (as

Ocean Current Energy: Underwater Turbines

Horizontal axis turbines typically look similar to wind turbines as shown in Fig. 3. They harvest kinetic energy from the moving water in the same way that wind turbines extract energy from the moving air. Ducted Horizontal Axis Turbines. The horizontal rotor is enclosed inside a duct. These ducts are often funnel-shaped and work by concentrating the current flow through the turbine. This

GE Panametrics Ultrasonic Flow Meter

Ultrasonic Flow Meter Part II Transducer Installation 3. The transducers can be installed on a horizontal run of pipe or a vertical run of pipe with flow going up. Avoid installing transducers on a vertical run of pipe with flow going down unless it is known that the pipe will always be full. In this configuration, intermittent flow will usually prevent establishment of a steady ultrasonic

The Colors of Our Emotions Marc Brackett, Ph.D.

The Mood Meter, based on the circumplex model of affect, defines emotions as having two dimensions, pleasantness and energy. On the Mood Meter, the horizontal or x-axis is pleasantness: our subjective, private mental experience. It represents how pleasant or unpleasant we feel, from -5, the most unpleasant we have ever felt, to neutral in the middle, all the way to +5, the most pleasant we
