Protecting GE 2.X Blades from lightning damage

GE 2.X blades are experiencing excessive lightning damage. We know why this is happening, and we detailed the issues in a recent article in PES Wind magazine. Unless you’re involved in turbine blade design, the more immediate concern is what to do about it.

Here’s what you need to know.

Protecting GE 2.X Blades from lightning damage

Cost-effective Protection Against Lightning Damage

GE 2.X blades are experiencing damage about 1 in 10 lightning strokes – that’s five times the “normal” levels defined in IEC. It’s happening for a number of reasons involving tip shape, high speed, leading edge erosion and some other factors.

Lightning damage costs money – and in addition to downtime and repairs, it’s often not covered by insurance.

StrikeTape protects blades by directing lightning safely to the blades’ existing receptors. When lightning strikes, the best-case scenario is that it hits the receptors; that’s how the design is supposed to work.

StrikeTape is cost-effective, simple and fast to install. This video describes the simple four-step process. One tech, on ropes, a platform or on the ground during component exchange, can add StrikeTape to a blade in a matter of minutes.

StrikeTape is protecting more than 16,000 blades worldwide. Learn more about it here, watch the video, or just contact us for a consultation and to order now.

When they watch the video they’ll understand the installation process and then they can enter to win a Yeti cooler and some other cool swag.

Why the GE 2.X?

As I explained in the PES Wind article, my first career experience was working for GE, and this is not a personal knock on the blades. It’s a known problem with the 2.X blades as I and others in the field have noted, repeatedly, and operators in the US midwest and western states are experiencing especially high losses from damage.

In talking to those who have installed StrikeTape, the results are immediate and clear – fewer strikes, dramatically less downtime and damages.

The Bottom Line?

Watch the video. Enter to win the Yeti. Give us a call if you have questions. Order StrikeTape and protect your blades.

Homeschooling

Published

Decent and intelligent people respect the rights of parents to homeschool their children, but there are two reasons for concern: a) socialization, failure to expose children to their peers, so that they may make friends and come to understand the norms of society, and b) the quality of the education itself.

Almost all homeschooling in the United States is conducted on the basis of a radical rightwing viewpoint, normally a blend of evangelical Christianity and Trumpism.

The Positive Effects We’ve Had on Others Are Profound, Whether We Know It or Not

There’s a theory that most people underestimate the positive effects they’ve had on other people.

Yes, that’s the theme of “It’s a Wonderful Life,” but it’s also the core of the 1995 film “Mr. Holland’s Opus,” in which a music teacher who deemed that his life had been a failure because he never completed writing a great symphony, is gently and beautifully corrected. Please see below.

Renewable Energy Concepts Can’t Violate the Laws of Physics

In the early days of 2GreenEnergy, my people and I were vigorously engaged in finding solid ideas in cleantech that needed funding in order to move forward.

I vividly remember a conversation with a guy in Maryland who was trying to explain the (ostensible) breakthrough that he and his team had made in hydrokinetics. When I was having trouble visualizing what we was talking about, he asked me to “think of it as a river in a box.”

“Oh!” I exclaimed. “You mean you take a box full of standing water, add energy to it get it moving, then extract that energy, leaving you with more energy that you added to it.”

“Exactly.”

I politely explained that the laws of physics, specifically the first and second laws of thermodynamics, make this impossible.

He wasn’t through, however, and insisted that, in his office, his people had constructed a “working model.”

Here’s where my tone descended into something less than 100% polite. I told him that he may think he has a working model, but he’s wrong; if he believes this, he’s ignorant; if he doesn’t, but is conducting this conversation anyway, he’s a fraud.

“But don’t you want to come see it?” he implored.

“No. Not only would not fly across the country to see whatever it is you claim to have built, I wouldn’t walk across the street to a “working model” of something that is theoretically impossible.”

I tell this story because the claim made at the upper left is essentially identical.  You’re pumping water up out of a stream, and then claiming to extract more energy when the water flows back into the stream.

Of course, social media today is rife with complete crap like this.  We’ve devolved to a point where defrauding money out of idiots is rapidly replacing baseball as our national pastime.
