New Product -- Anemometer Cup and Hub Assembly

[(unknown)]

A really nice unit made of durable Polycarbonate (Lexan®). Mounting, glueing and balancing those durn Easter Eggs was a pain in the butt. With this thing, you just press the cups into the hub and are ready to rock n roll.

**********

A quick and easy way to build your own anemometer! A windspeed meter is essential both for evaluating a site for wind power potential, and for measuring the performance of your wind turbine. The most tedious part of building our Easter Egg Anemometer was fabricating and balancing the cup assembly. This product makes that easy! You can use it for any design, including bicycle speedometer versions.

The 3 cups and the hub are made from extremely durable black polycarbonate plastic (Lexan®). They ship unassembled, and the cups simply press fit very firmly into the hub -- no glue is needed. In both of the anemometers we built with these cups, no balancing was needed. There is a 3/32 inch diameter reinforced hole in the exact center of the hub to make fitting your own shaft, bearing, or surplus gadget to the hub fast and easy.

The total diameter of the unit is 4.125 inches. Each cup is 2.5 inches in diameter. The hub is 1.5 inches in diameter and 1.375 inches deep.

No sensing apparatus is included, that is up to you. This product includes the cups and hub assembly only.

Sorry, could not resist!

What do you call a device for measuring the speed of certain carniverous invertabrate creatures across the ocean floor?

An "Anemonemenometer"

That was horrible! In tribute to Callahan's Place custom, picture me holding my nose and running screaming into the night.

A group this wacky DOES read science fiction/fantasy, right?

hi

do you think that i can make something like this but bigger and put it on a dc motor and use it as a wind gen ?

[troy]

You sure can.  It's called a drag machine because it uses drag and not lift like a "propellor" based mill.  Drag machines are generally pretty good on torque and pretty bad on rpm.  Plus the tip of the rotor (like the cup on the anemometer) can never go faster than the ambient wind speed, which is much much different than a machine with a prop.  The tip speed on a prop will run anything from 3 to 10 times faster than the ambient wind speed.

A Savonious rotor is another example of a common drag machine.

Best regards,

Any idea when these will be in stock again??
