JJC:    Lately, we've been infatuated with... wind power!   That's right, wind power is our favorite renewable energy source, because it's the cleanest, it's the cheapest, it's 4 cents a ready kilowatt...  It doesn't need subsidies, unlike most solar except, perhaps, First Solar (FSLR)...

It can be built in incredibly isolated areas that nobody cares about, and we've got tons of them...   And, according to the Department of Energy... maybe it will provide 30% of our nation's energy by 2040...  And it's the most chock full of technology that our favorite new companies...  you know, our "new tech" companies make right here in America...

That's why, tonight, I'll be breaking more wind than usual...  taking the wind story up a notch.

We're going to build two things on tonight's show...

First, is a windmill... out of stocks that make each part... and then, are you ready, skee-daddy?...  a Mad Money Wind Index... or, what we will call Wind-Ex...

We'll take all the stocks that we use to build the windmill with... which I believe will create an accurate indicator of the overall wind trend...

Now, I want to point out that these are not necessarily my recommendations... That's right... I only like a couple of these... but it doesn't matter... Use it as a gauge by which to measure what I think is a major up-and-coming trend... not a recommendation of all of them... just a trend recognizer...

It amazes me that there isn't a single Wind ETF on the market right now, which is another reason why I love this wind theme... It shows that, in Cramerica, we are thinking of the things the big boys haven't thought of yet... like the Wind-Ex play...

Of course, we figure the vaunted brokerage industry will steal this idea, and credit themselves for the idea, which is why we're calling it the Mad Money Wind-Ex... so you can at least chuckle when they shamelessly pilfer the idea... You'll know the truth!...

We're doing this piece today, because I don't want you to miss more great performance form wind, and wind-related stocks... and Wind-Ex...

You see, I've been recommending stealth wind plays, and other wind-related stocks... seven in total... since April 24th...

Trinity Industries Inc. (TRN), whose CEO we'll be talking to later on... Otter Tail (OTTR)... Owens Corning (OC)... Woodward Governor (WGOV)... MasTec (MTZ), Thomas & Betts (TNB)... Well, you get the point! Our wind stocks have beaten the S&P by an average of 9.7% since I picked each one and profiled them.

All seven of these stocks are going into the Wind-Ex... but I want you to understand how a wind farm works, so we're going to put together a windmill... all the parts... to show you where each of these stocks goes... and we're going to add four more stocks that I think will round out this sector as a whole, as part of the Wind-Ex...

First, there's the wind tower... used to support the entire wind turbine... Who makes them?... Perhaps you ask, plaintively... Trinity (TRN) does... through its subsidiary, Trinity Wind Structures... Otter Tail (OTTR)'s DMI Industries subsidiary makes it... a division that I think could be worth as much as the whole company is worth now... You could say that about TRN's business too...

These are stocks I've already recommended. They go into the Mad Money Wind-Ex...

There are three other companies that are making towers that I haven't mentioned yet, and I think they belong in the Wind-Ex too... There's Ameron (AMN). I mentioned that last night... I said I had to kill the piece (i.e., the feature TV show segment), because it went up $12 ahead of me. That's an engineering company that mainly makes water pipeline systems in the western U.S.... That's a terrible business, but it also has a wind tower manufacturing business that could double in size in 2008. I like AMN, especially because it's under-covered... so AMN joins the index. Be careful! It missed the quarter terribly, but it does have a great wind business...

The next company I think is important here is Vestas (VWDRY.PK), which is the largest play in the global wind market, and the largest maker of wind turbines. It makes towers, in addition to other components that we'll get to in a moment... The stock trades in Denmark, so normally we would not cover it on Mad Money... but, because it is such a big player, we would be remiss in excluding it. I want you to know that it trades over-the-counter here in the U.S.... meaning it is thinly traded... much more volatile than the stocks we usually talk about on Mad Money...

Now, the third company that makes towers is Broadwind (BWEN.OB). This one also trades over-the-counter. The same concerns apply. I think its stock could make a big move higher. It already has, but it would make a big move higher if it also moved its listing to an exchange, where the big institutions might take an interest in it. BWEN is also in other parts of the windmill, so you'll hear it again shortly...

That's the tower.

Next... next, you've got the blades. You probably know what they look like. They're the part of the wind turbine that captures wind energy, and spins to move the turbine. I talked about Owens Corning (OC)... This makes the composite materials used in the production of the blades. It belongs in the index. And, yes again, Vestas (VWDRY.PK), that full-service, one-stop shop wind turbine company that we already discussed earlier. It makes the blades for its own turbines.

The next part of the windmill is the nacelle...

This houses all the parts and equipment needed to take the energy from the blades, and use it to generate current, and create electricity...

Woodward Governor (WGOV) makes power systems for the nacelle. Thomas & Betts (TNB) makes electrical components... Kaydon (KDN) makes bearings... Broadwind (BWEN.OB) makes gears... All of this is for the nacelle... and Vestas (VWDRY.PK) makes its own integrated nacelles... and so does a company that I haven't talked about before, because, again, it trades over-the-counter, which means that it's a riskier play than the stocks you usually hear me talking about... The company is Clipper (CRPWF.PK)... That's a turbine manufacturer based in the U.K., where its business is particularly strong... CRPWF is also involved in wind farm construction and ownership of wind farms.

Then, finally, we've got the wind farm construction and infrastructure piece of the puzzle... the equipment needed to build a wind farm to get it connected to the grid... MasTec (MTZ), which I've talked about before, has a wind farm construction and repair business. So does BWEN... Clipper (CRPWF.PK) does construction too... And Thomas & Betts (TNB) makes steel transmission towers for connecting the wind farm to the grid.

We've built the windmill... And, now, we've got 11 stocks for the Mad Money Wind-Ex... The seven I've talked about before... Trinity (TRN), Otter Tail (OTTR), Owens Corning (OC), Woodward Governor (WGOV), MasTec (MTZ), Thomas & Betts (TNB), and Kaydon (KDN)... plus the four new ones... Vestas (VWDRY.PK), Ameron (AMN), Clipper (CRPWF.PK) and Broadwind (BWEN.OB)...

Again, these are not all my picks... This is not a bucket of stocks that I think you all should be in... and, if you think you want all of these stocks, you would flunk "Am I Diversified" miserably...

I like these stocks as a representation as a way to gauge the trend in this booming wind market.

Also, there's a special reason why I'm unveiling the Mad Money Wind-Ex today...

We've got a catalyst!... The American Wind Energy Association is holding its Wind Power 2008 conference in Houston... running from June 1st to June 4th... Companies from all over the industry will be coming together to talk shop, and I think this will drive more interest in wind... 7,000 attendees, and 420 companies at the conference last year... This year, I'm expecting 10,000 people and 770 exhibiting companies...

Trinity (TRN), Otter Tail (OTTR), Woodward Governor (WGOV), Thomas & Betts (TNB), Ameron (AMN), Vestas (VWDRY.PK), Broadwind (BWEN.OB) and Clipper (CRPWF.PK)... They will all be there. That's 8 out of the 11 stocks in our Wind-Ex! I think it will be a great venue for them to report new orders and new technologies that could send any of the stocks higher.
