Brazil is known for attractive women, Carnival, the Amazon, Samba and even a popular waxing procedure. But will a giant waterfall soon be added to the list?

In an effort to make Rio's Olympics in 2016 the first ever zero-carbon games, the city's proposed Solar City Tower will include solar panels. The building is designed to create renewable energy for use in the Olympic Village as well as the city of Rio. A large solar power plant generates energy during the day, and any excess power is used to pump seawater into a storage tank within the tower. At night, the water will be released and provide nighttime power for the city.

And during the Olympic games, water will be pumped out to create a massive, sky-high, artificial waterfall over the edges of the building.

On the ocean side of the tower (behind the waterfall) will be a cafeteria and shop. Visitors can even go up to the top floor, where an observation deck will offer 360-degree views of the ocean and city. And -- you knew this was coming -- a bungee platform will be available for adventurous visitors.

But just how “sustainable” and “green” is this structure, really? The building architects say the waterfall is meant to be "a symbol for the forces of nature." But isn’t that what the "Waterfalls" art installation in New York City was supposed to be? That display sprayed salt water into the air that killed some of the surrounding greenery.

So while the hope is to create an icon for Rio's Olympics that's as forward-thinking as the country itself, if there is one thing we already know about waterfalls, it’s don’t go chasing them.

No, Notre Dame quarterback Dayne Crist did not attach his cell phone to the left side of his helmet. That's a camera placed there by his head coach, Brian Kelly.

Kelly commissioned the rig to get a better look at the decision-making processes of Dayne Crist and fellow signal-caller Tommy Rees.

“If he’s staring down a particular receiver, you’re going to see that,” Kelly told the South Bend Tribune. “If he’s moving his eyes through his progression, you’re going to see that.”

Colorado tried similar technology last year (see below). The camera is lightweight and unobtrusive, and the footage will be easy to download for film room review. For the moment, there are no plans for the project beyond spring practice. And no word on whether Kelly has asked for similar cameras to be installed on referees' caps.

Qatar won the bid to host the 2022 World Cup by promising that its nine new open-air soccer stadiums would be air-conditioned. Now the Qataris have announced another cool twist to their hospitality -- an artificial cloud to hover above the stadium and provide shade.

The head of mechanical and industrial engineering at Qatar University said the cloud would be positioned by remote control and run on solar power.

Based on the design shown in local Qatari news outlets, the cloud isn't white and fluffy. It is flat and rectangular, resembling a giant cell phone, and will be built using light carbonic materials. Perhaps something was lost in translation from Arabic because the invention is more spaceship than cloud, but ultimately players and fans will benefit from the shade.

The cost of the cloud is $500,000, but money is no obstacle for Qatar, which is one of the world's richest countries thanks to vast natural gas and oil reserves.

There have been concerns about the heat ever since Qatar began its campaign in 2009 to pursue a World Cup. The average high for July in Qatar is 106 degrees, and temperatures have reached 120 degrees in the summer. That is one reason why Prince Ali of Jordan suggested shifting the 2022 World Cup from its traditional time in July to January, which is Qatar's coolest month with an average high of 71 degrees.

Temperatures were in the 60s for the 2010 World Cup championship match in Johannesburg, South Africa, held on July 11, between Spain and the Netherlands.

Qatar, which is roughly the size of Connecticut, will be the smallest nation to host a World Cup. The other finalists to host in 2022 were the U.S., Australia, Japan and South Korea.

Smell-o-Vision was definitely one of the more gimmicky technologies of the 1960s. Early attempts to realistically pump scents into movie theaters were as technologically sophisticated as a "Scratch and Sniff" card.

Since then, companies have tried to replicate the “science.” In the late '90s, for instance, a company called Digiscents attempted to create a device called the iSmell that could be used to experience scents as you were surfing the Internet. Instead of being revolutionary, it earned the distinct honor of being named one of the 25 worst tech product names ever. (Seriously? iSmell?)

But two new companies, Scent Science and Sensory Acumen, are putting a more sophisticated -- and much cooler -- 21st century twist on this previously ridiculous technology. Using atomizers and a computer or game console connection, these devices spray scents into the air that correspond directly with the games you're playing or the movies you’re watching. Talk about reality TV.

The ScentScape lets users customize their own “scent information” to release certain smells related to the action in video games. In the future, gaming companies could sell racing simulation games with the scent of rubber and gasoline, golf games wafting of freshly-cut grass, or boxing games that smell like sweat (although I don’t know who would buy that). And if gamers can create their own, personalized scented games, players could share them with other gamers as a way to enhance and share the experience.

Some may think this is sensory-overload, but I welcome the chance to enjoy the scent of strawberries and cream with my Wimbledon. Though let’s make sure we can turn ScentScape off during horse racing events, OK?

Ever notice how much bigger JumboTrons are getting? Or how many things you can do at stadiums that actually have very little to do with the actual game?

Maybe you’re finding that you’re spending more time watching the HD stadium screen than you spend watching the players on the field. The monstrous television is both magnificent and distracting, which may say more about the future of sports stadiums than you realize.

The Business Insider Sports Page lists 14 innovations that will make stadiums of the future almost unrecognizable.

The recurring theme is that convenience is key, and you’ll be overloaded with more options and access to information, players and entertainment than ever before. And the choices certainly sound appealing.

If you’re a fantasy nut, players’ complete statistics will be available in real time.

If you’re a parent with kids that need to be distracted, more rides and games will be accessible throughout the stadium.

If you snuck out of the office for a game, free wifi throughout the venue will help keep you connected to work.

As a fan, you’ll be swept up by countless options tailor-made for you.

It sounds exciting, but is it really what we want? Will we be so swept up by information and access that we’ll actually be distracted from real sports? Will games become less of an escape if we’re always connected to the outside world? Where will the where-were-you moments go if we were there, but didn’t actually see the play?

Some of these innovations sound great. In fact, they all do. But if they make stadiums so user-friendly, it does raise the question: What’s wrong with what we’ve got now?

Someday, people will talk about the legend of Stevo Poulin.

Right now, the best we’ve got is a video on the web that puts the rest of us mere mortals to shame.

Poulin, an 8-year-old wrestler from Schuylerville, N.Y., is clearly good at three things: Being a bad little man, having a mean mohawk and throwing his opponents around like ragdolls on the mat.

In years past, when you wanted news on labor negotiations in professional sports, you turned to a small handful of insiders who worked for established media outlets. They relayed carefully crafted messages from the league's power-brokers to the people, and that was extent of the information the public received.

Things are different now.

We last faced the prospect of potential labor strife in the NFL in 2006, when the NFL and the NFL Player's Association nearly failed to come to terms on an extension of the Collective Bargaining Agreement. At issue wasn't an immediate work stoppage, but the potential of a work stoppage in 2008 were a deal not done. But during those negotiations -- behind closed doors -- former NFL commissioner Paul Tagliabue and former NFL Player's Association chief Gene Upshaw were able to strike a deal at the eleventh hour which preserved labor peace and allowed the NFL to keep rolling.

This time, though, the public has access to less-controllable information. Thanks to the impact of social media -- most notably Twitter -- not only has the public had a front-row seat to the labor negotiations as they have unfolded, but depending on who you ask, the public might even have a voice in the process.

Making Themselves Heard

Opinions differ on how impactful social media has been in labor negotiations thus far. But with the NFL standing alone as the most profitable sports league in the country, both the union and the league understand that fans are the ones who drive nearly $9 billion of revenue per year into the league's coffers, and a lot of those fans are signed up for one social networking site or another. As a result, both the union and the league have tried to curry favor with fans as labor negotiations have played out in an unusually public fashion.

David Cornwell, president of the sports law firm, DNK Cornwell, points out one example:

"When the NFL walked out (of a negotiation session) over the issue of whether the NFLPA's proposal was actually a proposal, their initial reaction was to not comment at all. But as not only traditional media, but also social media began to log in on the implications of whom did what to whom -- I think it was 2 or 3 days later -- the NFL actually came out with a statement that was a little bit more meaty in terms of what happened in the room."

The fact that the NFL was forced to do anything as a result of the voices coming from the cheap seats is a testament to the changed conditions these labor negotiations are taking place under. Previously, fans had less information to digest on the negotiations and no way to communicate their frustrations to anyone outside of their circle. As a result, most fans simply disengaged. But now, with the ability to access information and real-time social networks from anywhere, fans are not only informed about what is going on in the labor process, but they are making their voices heard.

Making Sense Of The Chatter

Long-time NFL agent David Canter, the CEO of DEC Management, sees a number of material differences between the current round of CBA discussions and those that occurred in 2006.

"Back in '06 we knew the 'fire and brimstone' talk about a lockout was probably a little more smoke and mirrors than it is right now," Canter says. "There is no doubt that we are at a much different stage. The union has been preparing players for well over a year. Last time we faced a lockout there wasn't that kind of preparation. There weren't any websites created to specifically warn players of what could happen, telling them that they needed to start saving money. It's just a much different negotiation."

Canter, who is one of the more active agents on Twitter, believes that things have become much more complicated for parties to the negotiation as a result of misinformation that often is given life through social media.

"In 2006, you had maybe 10 people who really had anything of value to report," he says. "It was just the insiders, people like Peter King, who had reliable, factual information. But now you have 500 Tom, Dick, and Harrys on blogs or other social media, and they're creating news that may or may not be accurate. Those kinds of things can spread like wildfire, and next thing you know is it's all over the news and being reported as fact when it isn't."

Canter was among more than 700 agents who attended a high-security NFLPA agent meeting last week at the NFL combine. The security was in place -- in part -- to ensure specific information didn't make it beyond the walls of the room. However, despite the protective measures, details of what was being discussed inside the meeting were being streamed on Twitter almost as quickly as they were said.

Those kinds of leaks put Canter and others involved in the process in the position of constantly having to clarify (cynics may say spin) information.

"Now, more than ever, you have to look out for people putting things out for the sake of creating that wildfire," he says. "You saw that (the other day), when it was reported as factual that the NFLPA will decertify on March 3rd, and that's not true. It's incorrect. We're being told that it's a strategy and possibility, but that no decision has been made and there are still some constructive aspects that can come out of talks Tuesday and Wednesday."

So yes, there is an incredible amount of information available to the average fan now, but the flip-side to to "inside information" is that you're not always sure that what you're hearing is accurate. For those who spend a lot of time on Twitter, you're well aware of how quickly information travels, false or otherwise.

Key Dates Ahead

The NFLPA's assistant executive director of external affairs, George Atallah, and NFL spokesman, Greg Aiello, are both on Twitter and have engaged each other a few times in the past few months. Whether veiled or direct, their interactions have given us all a glimpse into just how contentious the negotiations have been at times.

As Twitter's popularity has increased, stream-of-consciousness tweeting from players has as well, and that's not always a good thing for the Union. Back in January, Antonio Cromartie voiced his displeasure with the lack of information sharing between the league, the union, and the players in an interview, which other players perceived to be a break in the ranks. That led to a number of players calling him out though social media, including Matt Hasselbeck's public inquiry into whether or not Cromartie knew what C.B.A. stood for. Cromartie responded swiftly to Hasselbeck's question by telling the quarterback that he would break his face.

Not exactly the show of solidarity the union was looking for.

While it appears that the Cromartie incident may have been an outlier, one of the most important elements of whether the union will be able to hold its ground in this dispute is whether the players will be able to financially survive an extended lockout.

Should a lockout occur, there are three periods of time when you should be paying special attention to social media:

1) From now until 11:59 p.m. ET Thursday, when the CBA is set to expire. Traditionally, this has marked the start of free agency. That's the point in time when we'll know if the lockout is real.

2) The month of March, which is typically dominated by free-agency. Fans are accustomed to signings during this time, and players whose contracts are up for negotiation will begin to get antsy.

3) Late April and early May, when most teams are focused on solidifying their 53-man-roster,
and …

4) July. With the season starting at the end of the month players, coaches, front-office types and others are trying to squeeze in their last bit of vacation before training camp. This will be a particularly interesting time to have a direct line to the players' thoughts as you begin seeing how the players self-organize in the absence of the strict schedule they're used to.

"The future of the National Football League as we know it is at stake in the Collective Bargaining Agreement,” Canter says. “The dynamics of the way pro football will be viewed forever and eternity in this country are at stake. It could be the most cataclysmic thing to happen to a pro sports league in the history of the United States, and social media is a very scary aspect of that."

Exactly how scary remains to be seen, but for the first time in history, fans will have a seat near –- if not at –- the bargaining table.
