VortexIt’s no longer surprising to encounter 100-foot pinwheels spinning in the breeze as you drive down the highway. But don’t get too comfortable with that view. A Spanish company called  Vortex Bladeless is proposing a radical new way to generate wind energy that will once again upend what you see outside your car window.

Their concept is the Vortex, a bladeless wind turbine that looks like a giant rolled joint shooting into the sky. The Vortex has the same goals as conventional wind turbines: To turn breezes into kinetic energy that can be used as electricity. But it goes about it in an entirely different way.

Vortex 2

Instead of capturing energy via the circular motion of a propeller, the Vortex takes advantage of what’s known as vorticity, an aerodynamic effect that produces a pattern of spinning vortices. Vorticity has long been considered the enemy of architects and engineers, who actively try to design their way around these whirlpools of wind. And for good reason: With enough wind, vorticity can lead to an oscillating motion in structures, which, in some cases, like the Tacoma Narrows Bridge, can cause their eventual collapse.

Where designers see danger, Vortex Bladeless’s founders—David Suriol, David Yáñez, and Raul Martín—sees opportunity. “We said, ‘Why don’t we try to use this energy, not avoid it,’” Suriol says. The team started Vortex Bladeless in 2010 as a way to turn this vibrating energy into something productive.

 


Electrician Forum Brought to you by Schneider Electric

As industry experts you know the products you use everyday better than anyone and should have input on what information you receive about products and what could improve them.

Therefore, we want your insight on the biggest challenges or issues you face when installing loadcentres, breakers (CAFI, GFI's…) and other surge protection devices. We ask that you do not provide product specific details but rather your general issues and concerns or any questions that have come to mind while working with these product types. Provide us with your valued expert insight into the issues you have faced so manufacturers can better inform you about the installation and use of these products. Lets generate some discussion that will help guide the Industry.

Cloud

There has been a lot of talk about cloud computing and Software-as-a-Service (SaaS) models these days but both are relatively new to the lighting industry. Let’s take a look at what they are as well as their roles in commercial lighting.

What is cloud computing?

Cloud computing is the on-demand delivery of compute power, database storage, and applications via the Internet with pay-as-you-go or subscription-based pricing. Cloud computing means that instead of all the computer hardware, software, and data that you are using sitting somewhere inside your company’s network, it’s provided and managed for you as a service by another company and you access it over the Internet.

Lumens

This article is an excerpt from a technical brief, “Understanding LM-80, Lumen Maintenance, and LED Fixture Lifetime,” by Philips Color Kinetics.

Test results of lumen maintenance in conventional and LED light sources differ considerably. This is known as the lumen maintenance gap. These tests are performed to determine the useful life of a light source. But how do we compare lighting technologies satisfactorily if test results of a same designation do not mean the same thing? These lumen maintenance measurement distinctions are those we will examine in this article, as a clear understanding of this gap will have a significant impact on the installation, maintenance and replacement cost calculations of lighting products.

Jean-Marc Myette

By Line Goyette

Meeting people in our industry often comes with surprises. This was the case with Jean-Marc Myette, Business Development Manager of ABB’s Electrification Products Division and chair of the Board of Electro-Federation Canada’s Quebec section. Not only does he know the electrical industry down to the most minute product and technological innovations, he is also a professional car racer on sabbatical, and someone very involved in his business community and personal life.
