For the nearly 20 percent of the world’s population lives in areas without access to fresh drinking water, getting access is a matter of life or death. Inspired by the mechanics of a dripping air conditioner, French inventor Marc Parent was inspired to create a solution that could bring fresh water to the most remote, driest parts of the world.

Parent created a company, Eole Water, that produces wind turbines that literally pull fresh water out of thin air.  His solution, dubbed the WMS1000 uses the electricity generated from a windmill to collect and treat water without tapping into a water source such as a river, lake or well.

Eole Water is testing the invention in France and Abu Dhabi.  The invention, if the company can get the economics to work, looks to be a promising solution to the water crisis.

I recently interviewed Thibault Janin,  Marketing and Communication Director of Eole Water on the WMS 1000 turbine to find out what’s in store for this new technology.

How was the idea of a wind turbine that produces water developed?
Thibault Janin: The idea came from Marc Parent, founder of Eole Water, when he lived in the Caribbean, and was subjected to water shortages. He began to work on a system that could recover moisture from the air and transform it into water. Soon after, he returned to France. He patented the process and founded Eole Water.

Millions of people worldwide live in remote areas without any access to safe drinking water. What is the potential  for the Eole system to solve this issue?
Thibault Janin: Each unit can create 1,000 liters of drinking water using only moisture and powered only by wind. Let me highlight this word : CREATE. All existing solutions (wells, desalination, lakes/rivers pumping, etc.) only treat an existing source of water. Thus, what happens when there is no or no more water available? The WMS1000 can create water when there is no existing source available. That makes a difference. Our technology integrates water creation, water collection, water treatment and water local distribution.  The WMS1000 can produce and distribute water everywhere.

Today, people only use centralized distribution, from a center point to others. With our turbine, we wish to decentralize the water access. As the logistic and the process are easy to install and operate, it will be an answer to various issues like massive population movements that cause swelling of cities, increased diseases and therefore health care costs increasing, a door to agriculture or a local industry beginning. All economic or welfare starts with access to water. And this is what we provide.

Are any of these turbines in place and operational?
Thibault Janin: Wind turbines (first, second, third generation) can be seen at Eole Water Headquarters in Manosque in the South of France. The fourth one is used to make demonstration during shows and exhibitions. The fifth one, the WMS1000, is the real showcase of our actual company knowledge. It has been designed and manufactured between January 2010 and December 2011. Then first tested in France between January 2011 to August 2011, and second in Abu Dhabi (Mussafah) from November 2011 to April 2012. The final location of this turbine will be Dubai by the end of 2012. The location will be opened to public.

What’s the cost of production and operation of the turbine?
Thibault Janin: The WMS1000 has a price of $600,000. It has been designed to operate in very remote areas, which implies that the maintenance overheads are strictly reduced to minimum. The WMS1000 wind turbine has lifetime of 20 years minimum.

What is the potential for the turbine?

Thibault Janin: Thibault Janin: Do not look only at the 150 million potential customers for this technology. It is much more complex. Water is becoming increasingly scarce. Household needs in the matter should increase by 130 percent by 2030. At the same time, the WMS1000 is only one step in our development. Our range will expand to provide more precise and larger answers to communities with larger turbines featuring higher capacities of water production. We respond to a growing and constant global demand, not subjected to economic classical cycles, since water is essential to life.

What hurdles do you see standing in the way of bringing more of these wind turbines online?
The major challenge for Eole Water is to make this technology more competitive in terms of price per water cubic meter. Our technology must reach maturity as quickly as possible, at several levels: production, R&D, legal or business experience.

It all started with a headache.

Back in 2010, Kelsey Stewart thought the new head pain he had been feeling was a sinus infection. He saw a doctor, who prescribed him some anti-inflammatory medication that he hoped would take care of the problem.

But once he started vomiting uncontrollably — one day, he recalls, he vomited 21 times — he went to the hospital for further evaluation.

There, a CT scan of his head and further testing revealed the bleak truth: Stewart had brain cancer. And it was not just any kind, but a grade 4 glioblastoma multiforme (GBM). GBM is a very aggressive kind of cancer known for its grim prognosis.

“We were terrified,” Stewart says. “Everything you read about GBMs is just death everywhere, death, death, death. My neuro-oncologist said she’s never seen anyone survive this.”

Doctors told him that, without surgery, he was not expected to live more than a year. But even with surgery, risks were high. Operations to remove brain tumors are complicated. They are located in the delicate brain tissues, and a tumor often appears remarkably similar to healthy tissue in the brain. This means that the line between diseased and healthy tissue is almost indistinguishable, leaving surgeons few clues on where to cut.

Fortunately, his brain surgeon had been working on an innovative solution to address this challenge.

Neurosurgeon Dr. Aaron Cohen-Gadol at Indiana University Health Neuroscience Center had developed a method to make cancerous tumors glow, using a special new microscope filter and small amounts of a glowing compound called fluorescein.

“We wanted to find a way using this new technology to increase the safety for the patient and at the same time maximizing tumor resection,” he explains.

In the operating room, Cohen-Gadol infused a small amount of a fluorescein into Kelsey’s bloodstream. Within the baseball-sized brain tumor, microscopic breaks in the blood vessels allowed tiny amounts of fluorescein to leak out into the cancerous tissues to light up under the microscope. Through the filter of his microscope, the tumor glowed fluorescent yellow – almost like white clothing appears under a black light.

Cohen-Gadol says that the glowing tumor was “like a roadmap,” helping him identify tumor more easily and facilitating a more thorough removal.

Currently, many neurosurgeons are seeking similar ways to remove brain cancers more easily and thoroughly. One emerging area of research involves an experimental compound that makes brain tumors glow, called 5-Aminolevulinic Acid (ALA). Other surgeons in Japan have tried using fluorescein, but without the newly invented filter that Cohen-Gadol used, they had to use precariously high doses of the glowing compound until they could see an effect.

In the United States, fluorescein is the only drug already approved by the U.S. Food and Drug Administration and available to all hospitals — not just the few enrolled in the ALA trials. Therefore, this compound can theoretically be used by any neurosurgeon schooled in the techniques of the microscope filter Cohen-Gadol used.

“There is no question that without the dye, it is very challenging to remove these tumors; you have to use imagination and adjunct strategies like mapping the brain.” said Dr. Alfredo Quinones-Hinojosa, a professor of neurosurgery and oncology at Johns Hopkins Medical Institution who was not involved in Stewart’s treatment. “Using these dyes makes it a step easier for the patient to optimize outcomes for the patients.

“If these tumors fluoresce with a small amount of fluorescein, this can be of tremendous benefit for us to be able to remove these tumors from the patient.”

In fact, this technology can even be applied in other diseases in the brain. Cohen-Gadol says that fluorescein can also help in identifying brain aneurysms — a condition in which there is an abnormal, dangerous ballooning of blood vessels. He says that when looking for aneurysms, the healthy vessels glow yellow-green while the aneurysm remains uncolored, which makes for “an amazingly beautiful picture.”

Cohen-Gadol says he has used the fluorescein technique in more than 30 brain cancer patients already. In Stewart’s case, Cohen-Gadol managed to remove 99 percent of the tumor using the technology. Other doctors tell him it’s the cleanest removal they’ve ever seen. A few months later, he used the technique again to remove two smaller tumors in Stewart’s brain.

And after he was given less than a year to live, Stewart is now going on three years of survival. For this, he is extraordinarily grateful.

“Dr. Cohen-Gadol being able to see more tumor and go after it was a big advantage for me,” says Stewart. “Whatever new technology is out there to improve the chance of survival, you want to get as much as you can.”

(Reuters) – Global stocks edged higher and U.S. Treasuries prices rose on Monday as expectations of further stimulus from top central banks gave support to markets, while oil prices were volatile on concerns over a tropical storm in the Gulf of Mexico.

U.S. stocks rose, led by gains in Apple (AAPL.O), which hit a new high above $680 after a patent court win over South Korea’s Samsung Electronics (005930.KS) on Friday.

Investors are looking ahead to a meeting of central bankers at Jackson Hole, Wyoming, on Friday for clarity on what the Federal Reserve will do to stimulate the economy and how the European Central Bank will tackle the bloc’s credit crisis.

“There’s not much going on as we look ahead to Jackson Hole, and we might make some new lows in terms of trading volume going into that as investors wait,” said Dan Veru, chief investment officer at Palisade Capital Management LLC in Fort Lee, New Jersey, which oversees $3.8 billion.

Last week, volume in U.S. equities was among the lowest so far this year and a holiday in the UK kept trading light in Europe on Monday.

The Dow Jones industrial average .DJI was down 0.31 point, or 0.00 percent, at 13,157.66. The Standard & Poor’s 500 Index .SPX was up 2.89 points, or 0.20 percent, at 1,414.02. The Nasdaq Composite Index.IXIC was up 10.89 points, or 0.35 percent, at 3,080.68.

A gauge of world equities .WORLD was up 0.2 percent and the pan-European FTSE 300 .FTEU3 stock index provisionally closed up 0.5 percent.

U.S. crude fell 1.1 percent to $95.06 a barrel, while Brent crude futures fell 0.8 percent in volatile trading after giving up gains of more than $1 per barrel as tropical storm Isaac approached the Gulf of Mexico and traders assessed the prospect of lower crude oil use by temporarily closed U.S. refineries.

“Traders realize that there is more refining capacity at risk from this storm, and that the risk is also to oil consumption,” said analyst Tim Evans at Citi Futures Perspective in New York. “That’s why we see today that crude prices are off and near-term gasoline prices are rising. It is similar to the price action we had ahead of Hurricane Katrina.”

The euro was little changed against the U.S. dollar, holding most of its recent gains after a bigger-than-expected drop in German business sentiment raised hopes the euro zone’s largest economy will do more to revive the bloc’s growth.

The euro edged up less than 0.1 percent to $1.2513 holding below a seven-week peak of $1.2589 set last Thursday.

“The news clearly shows that Germany cannot escape unharmed if the rest of the euro zone falls into a deep recession,” said Boris Schlossberg, managing director of FX Strategy at BK Asset Management in New York.

“Therefore policymakers may now temper their insistence on austerity and instead will pursue more stimulative policies in order to revive growth.”

This view got a boost on Monday from Chicago Federal Reserve Bank President Charles Evans, who said in remarks prepared for delivery in Hong Kong that the Fed should start a new round of monetary stimulus immediately, buying bonds for as long as it takes to produce a steady decline in the jobless rate.

The possibility of more bond buying from the Fed lifted prices of U.S. Treasuries.

The benchmark 10-year U.S. Treasury note was up 10/32, with the yield at 1.6506 percent.

European Central Bank chief Mario Draghi signaled earlier this month that the bank may start buying government debt to reduce crippling Spanish and Italian borrowing costs, comments that fueled a broad-based upturn in sentiment on global markets.

However, over the weekend Bundesbank chief Jens Weidmann likened the ECB’s bond-buying plans to a dangerous drug, pointing to growing unease over the policy.

Gold prices hit their highest since mid-April on bets of more Fed easing, but then steadied on caution ahead of the Jackson Hole meeting.

(Reuters) – Samsung Electronics shares slumped 7.5 percent on Monday, wiping more than $12 billion off the South Korean giant’s market value, as a sweeping victory for Apple Inc in a U.S. patent lawsuit raised concerns about its smartphone business – its biggest cash cow.

Samsung, which says it will contest the verdict, was ordered to pay $1.05 billion in damages after a California jury found it had copied critical features of the hugely popular iPhone and iPad and could face an outright sales ban on key products.

“There are still too many variables including the final ruling to come at least a month from the recent verdict, and whether there will be a sales ban on Samsung’s main sellers such as the Galaxy S3,” said a fund manager at a Korean asset management company that was one of the biggest institutional holders of Samsung’s stock as of end-March.

Shares in Samsung – the world’s biggest technology firm by revenue – tumbled as much as 8 percent, its biggest daily percentage drop in nearly four years, to 1.173 million won ($1,000), before closing at 1.180 million won. The broader Seoul market fell 0.1 percent.

Trading volume was also heavy, with a total of 1.27 million Samsung shares changing hands, around four times the daily average it saw last week and the stock’s biggest daily volume since October 2008.

In the most closely watched patent trial in years, the jury at a federal court in San Jose, California, just miles from Apple’s headquarters, found that Samsung infringed on six of seven Apple patents.

The verdict, which surprised many analysts with its speed – coming after less than three days of deliberations – and the extent of Apple’s victory, will likely solidify the U.S. firm’s dominance of the exploding mobile computing market.

Apple’s triumph was also seen as a blow to Google, whose Android software powers the Samsung products that were found to infringe on Apple patents.

But it could help Microsoft, which has been struggling to win ground with its rival Windows mobile operating system. Shares in Microsoft’s handset partner Nokia jumped 6 percent in early trade on Monday.

Analysts estimate Samsung’s earnings will be reduced by 4 percent this year due to increased patent-related provisioning.

“Samsung should be OK – it means a 4-5 percent hit to the bottom line,” said a Hong Kong-based hedge fund manager who declined to be identified.

“Both companies are in the midst of a squabble but I don’t think it’s a structural negative for Samsung. At the end of the day, as Forbes reported recently, Samsung has 65,000 patents versus 9,000 for Apple. Furthermore, Apple relies on Samsung for the processing brains of their phones. I sold Samsung four months ago but am watching the stock closely now.”

The court case had weighed on Samsung’s stock in the week leading up to Friday’s verdict, but even after Monday’s slide it remains up around 75 percent over the last 12 months, during which time galloping smartphone sales have powered record profits.

The phone and tablet business now accounts for around 70 percent of earnings for Samsung, which made a net profit of $4.5 billion in the April-June quarter.

EYES ON GALAXY S III

Apple plans to file for a sales injunction against Samsung, its lawyers said, and the judge in the case set a hearing date for September 20. Samsung, in turn, said the verdict “is not the final word in this case”.

Top executives at Samsung, led by Vice Chairman Choi Gee-sung and head of its mobile division JK Shin, held an emergency meeting on Sunday.

The biggest concern for Samsung remains whether its latest flagship product the Galaxy S III, which was not included in the case, will also be targeted by Apple. The model is Samsung’s best selling smartphone, with sales topping 10 million since its late May debut.

But Samsung’s skill as a “fast executioner” – quick to match others’ innovations – would likely mean tweaked, non-patent infringing devices would be on the market soon after any ban came into place, Morgan Stanley analysts said in a note.

“Outcomes of patent cases as well as their direct commercial effects are hard to gauge and often take time to resolve,” said another Hong Kong hedge fund manager who focuses on South Korea. “For now, I would be neutral until better clarity or cheaper levels.”

Samsung was disappointed by the verdict and plans to keep up the legal fight to have its claims accepted, according to an internal memo sent to its employees and released to the media.

“We’ve sought to settle this through negotiations, as Apple is our customer but had no choice but to counter sue,” the memo said. “History has shown there has yet to be a company that has won the hearts and minds of consumers and achieved continuous growth when its primary means to competition has been the outright abuse of patent law, not the pursuit of innovation.” ($1 = 1134.05 Korean won)

(Reuters) – GlaxoSmithKline has completed final stage testing of its experimental once-daily lung disease drug LAMA/LABA and will press ahead with plans to file for approval of the medicine in global markets from the end of 2012.

In a statement on Friday, the British drugmaker said a 52-week safety study, the last in a program of trials which also included four pivotal studies of the drug, was now complete.

GSK, which is developing the LAMA/LABA combination medicine with Theravance, said in July that it had showed positive results in four late-stage trials in patients with chronic obstructive pulmonary disease (COPD).

“The full results of all these studies … will be presented at future scientific meetings,” the firm said.

LAMA/LABA is a combination of two molecules – umeclidinium bromide (UMEC), a long-acting muscarinic antagonist (LAMA) and vilanterol (VI), a long-acting beta2 agonist (LABA), administered by a new dry powder inhaler.

GSK is working hard to develop next-generation medicines to become successors to its $8 billion lung drug Advair.

Advair and Pfizer’s Spiriva currently dominate the respiratory drug market, but Swiss firm Novartis is also fighting the next generation battle with its experimental combination drug QVA149, which some analysts are already tipping as a potential $5 billion-a-year seller.

(Reuters) – Stocks gained on Friday on news the European Central Bank is considering setting targets in a new bond-buying program that could help contain euro-zone borrowing costs and on hopes of more stimulus from the Federal Reserve.

Despite the day’s advance, the S&P 500 broke a six-week string of gains. For the week, the benchmark index fell 0.5 percent loss. Conflicting perceptions of the Fed’s commitment to provide more stimulus took a toll on the market this week.

Investor sentiment received a lift on Friday from U.S. Fed Chairman Ben Bernanke, who said the Fed has room to deliver additional monetary stimulus to boost the U.S. economy. Bernanke made the comment in a letter to a congressional oversight panel.

The letter comes a week ahead of the annual economic symposium at Jackson Hole, Wyoming, where Bernanke and ECB President Mario Draghi will speak.

The ECB is discussing yield-band targets under a new bond-buying program to let it shield its strategy and avoid speculators trying to cash in, central bank sources told Reuters on Friday. Any decision would not be made before the ECB’s September 6 policy meeting.

“If there can be a nice balance of stimulus that keeps interest rates low, as opposed to throwing more debt at the problems in Europe, and some level of austerity, Europe can get out of this tangle. But that balance is really the key,” said Bryant Evans, investment advisor and portfolio manager at Cozad Asset Management, in Champaign, Illinois.

The market’s gains were fairly broad. The S&P financial index .GSPF rose 0.6 percent and the S&P consumer discretionary index .GSPD climbed 0.8 percent.

The Dow Jones industrial average .DJI rose 100.51 points, or 0.77 percent, to 13,157.97 at the close. The Standard & Poor’s 500 Index .SPXadded 9.05 points, or 0.65 percent, to 1,411.13. The Nasdaq Composite Index .IXIC gained 16.39 points, or 0.54 percent, to close at 3,069.79.

Volume was the second lowest for a full day this year, with 4.6 billion shares trading on the New York Stock Exchange, the Nasdaq and the Amex. The year-to-date average is 6.6 billion.

The Dow also broke a six-week string of gains, losing 0.9 percent for the week. The Nasdaq lost 0.2 percent for the week after posting five weeks of gains.

In a letter to a congressional oversight panel on Friday, Bernanke said, “There is scope for further action by the Federal Reserve to ease financial conditions and strengthen the recovery.

Early in the day, the S&P 500 briefly fell below the 1,400 level following cautious comments from German Chancellor Angela Merkel about Greece staying in the euro zone.

It was the first time in two weeks that the benchmark S&P 500 had dipped below 1,400.

“Intermediate-term, weekly indicators, tracking one- to two-quarter shifts are not yet overbought and, in theory, have potential to carry equities higher into the fall,” said Robert Sluymer, an analyst at RBC Capital Markets LLC, in New York.

Among gaining stocks, Supervalu (SVU.N) shares jumped 10.9 percent to $2.35 as the U.S. grocery company’s advisers sought potential buyers to bid for the entire business, even as several suitors have inquired about its individual parts, according to a Bloomberg report.

On the downside were shares of Autodesk (ADSK.O), which slid 15.6 percent to $30.13. The stock was downgraded by various brokerages a day after the design software maker’s quarterly results fell short of expectations for the first time in nearly two years.

On the data front, new orders for durable goods, which are long-lasting U.S. manufactured goods such as computers and aircraft, surged in July, even as declines in a gauge of planned business spending pointed to a slowing growth trend in manufacturing.

The mixed data added to the market’s uncertainty on whether the Federal Reserve will act soon to bolster the economy.

Today’s new home sales showed some signs of life.  Combined withyesterday’s existing home sales report it seems that the housing market has left a bottom behind and is on a bumpy road to recovery.

New homes sold at a seasonally adjusted annual rate of 372,000 in July, according to the Commerce Department.

This is 3.6 percent above the rate a month ago and 25.3 percent more than a year ago, just a bit higher than economist expectations.

New home sales are still well below levels seen in a healthy economy but now match a two-year high.

Last time the housing market was showing signs of life was thanks to a government program offering tax benefits to new home buyers.  Not so this time.

New home sales are a small chunk of the housing market but they have an important ripple effect in the economy.

One more nugget out today on housing.

Home prices rose 1.8 percent in the April-June compared with the first quarter of the year, the Federal Housing Finance Agency said Thursday.

It was the biggest quarterly jump since the fourth quarter of 2005, when prices rose by 2.2 percent. Prices were up 3 percent from the same quarter a year earlier.

Meanwhile, mortgage rates, which reached historic lows earlier this summer, moved higher for the fourth consecutive week.

The 30-year fixed-rate mortgage averaged 3.66 percent for the week ending Aug. 23, up from last week when it averaged 3.62 percent. Last year at this time, the 30-year rate averaged 4.22 percent, Freddie Mac reported.

The 15-year fixed-rate mortgage averaged 2.89 percent, up from last week when it averaged 2.88 percent. Last year in the same period, the 15-year rate averaged 3.44 percent.

By The Associated Press

Average U.S. rates on fixed mortgages have risen for a fourth straight week, remaining slightly above record lows. Cheap mortgages have helped fuel a modest housing recovery this year.

Mortgage buyer Freddie Mac says the rate on the 30-year loan increased to 3.66 percent, up from 3.62 percent last week. Four weeks ago, the rate fell to 3.49 percent, the lowest since long-term mortgages began in the 1950s.

The average on the 15-year fixed mortgage, a popular refinancing option, edged up to 2.89 percent. That’s up from 2.88 percent last week and from the record low of 2.8 percent four weeks ago.

The availability of low rates has lifted home sales higher this year. Prices also have increased, largely because the supply of homes has shrunk while sales have risen.

Builder confidence is also at its highest level since March 2007, according to a survey by the National Association of Home Builders.

The housing market’s recovery will likely add to economic growth in 2012 for the first time in seven years. Home purchases, construction and prices are gradually but consistently increasing, though they remain far below levels seen in a healthy economy.

Sales of previously occupied homes rose 2.3 percent in July from June to a seasonally adjusted annual rate of 4.47 million, the National Association of Realtors reported this week. Over the past 12 months, sales have jumped more than 10 percent.

New-home sales have been strengthening, too. Sales in the United States rose 3.6 percent in July to match a two-year high reached in May, the Commerce Department said Thursday. The seasonally adjusted annual rate last month was 372,000, though still well below the 700,000 pace that economists consider healthy.

Toll Brothers, a builder of high-end homes, is enjoying its most sustained demand in more than five years.

All of which is a big change for the residential real estate industry, which has been a major drag on the economy since the housing bubble burst more than five years ago.

Still, the housing market has a long way to go to reach a full recovery. The pace of home sales remains well below healthy levels. Many people are still having difficulty qualifying for home loans or can’t afford larger down payments required by banks.

Mortgage rates are low because they tend to track the yield on the 10-year Treasury note. A weaker U.S. economy and uncertainty about how Europe will resolve its debt crisis have led investors to buy more Treasury securities, which are considered safe investments. As demand for Treasurys increase, the yield falls.

To calculate average rates, Freddie Mac surveys lenders across the country on Monday through Wednesday of each week.

The average does not include extra fees, known as points, which most borrowers must pay to get the lowest rates. One point equals 1 percent of the loan amount.

The average fee for 30-year loans was 0.7 point, up from 0.6 point last week. The fee for 15-year loans also increased to 0.7 point from 0.6.

The average rate on one-year adjustable rate mortgages fell to 2.66 percent from 2.69 percent last week. The fee for one-year adjustable rate loans was unchanged at 0.4 point.

The average rate on five-year adjustable rate mortgages rose to 2.8 percent from 2.76 percent. The fee held steady at 0.6 point.

Americans purchased more new homes last month, the Commerce Department said Thursday, but put prices fell in July, offering mixed signals about the strength of a nascent recovery in the housing market.

The government said new home sales for July rose 3.6 percent to a seasonally adjusted 372,000-unit annual rate, matching a two-year high seem in April. Economists forecast a total of 365,000 annualized units. Compared to July last year, new home sales were up 25.3 percent.

“The data is modestly better than expected, so from that perspective it is a constructive report,” said Jacob Oubina, a senior economist at RBC Capital Markets in New York.

Still, home sales are bumping along at very low levels, he added, predicting a slowdown in home purchases after the summer.

The housing report showed prices dropped last month, with the median price of a new home down 2.5 percent in July from a year earlier to $224,200.

The government’s estimates for new home sales are prone to substantial revisions, and June’s sales pace was revised up to 359,000 units from the previously reported 350,000 units.

The July housing data follow a report Wednesday from the National Association of Realtors that showed more Americans purchased previously-owned homes last month, suggesting improvement in the beleaguered housing market over the summer.

Low interest rates and a modest improvement in the labor market helped home-buying conditions, the NAR said. Other trends that are helping housing include mortgage rates, which are at near-record lows, and housing prices that are down sharply from the mid-decade housing bubble period.

Wednesday’s housing number was seen as the latest sign that the housing market, which is beginning to recover from the after-effects of the financial crisis, is perking up. Recent data show sales and prices are becoming stable.

On Wednesday, luxury homebuilder Toll Brothers reported higher quarterly profit and a strong increase in new orders.

“We are enjoying the most sustained demand we’ve experienced in over five years,” Douglas C. Yearley, Toll’s chief executive officer, said in a statement.

If recent campaign events by both the Democratic and Republican presidential candidates are any indication, energy policy is going to be a major political chip in the race for the White House.

President Obama and Mitt Romney have diametrically opposed views on energy security, efficiency, and innovation. That brings seemingly minute issues such as a wind tax energy credit (crucial to Iowans, coincidentally) to the forefront as well as more philosophical issues such as whether the government should subsidize companies researching and producing renewable energy sources.

But beyond the media blitz surrounding a few select issues in a few select politically important states, a host of other energy issues affecting America’s energy security and future remain hidden from public discourse.

Here’s a look at just a few prickly, but important, energy issues that few are talking about:

The coal industry. Though it might seem like a business from a bygone era, coal mining and its use to produce energy are still key issues for many states, including some that could go either way come the November election.

[Read: Wind Energy Tax Credit: More Hot Air or Key Job Creator?]

That isn’t lost upon Mitt Romney, who visited eastern Ohio in a campaign stop last week. Surrounded by some 75 miners, the Republican challenger pledged his support for the industry and dinged the Obama administration’s tight regulation of coal plants.

But regulation of coal plants isn’t the only thing that’s squeezing the industry. Plentiful natural gasreserves have made the United States the largest natural gas producer in the world, according to the Institute for Energy Research, and that’s made deposits of the resource in Texas, Alaska, and Wyoming increasingly attractive.

“Neither candidate’s position [on the future of the coal industry] has been terribly well defined,” says Mike Lynch, president and director of global petroleum service at Strategic Energy & Economic Research. “The big challenge right now is that coal is being clobbered by cheap natural gas not so much by regulation, and neither [Romney] nor Obama has addressed that.”

Although coal is relatively cheap, it hasn’t been able to compete with the flood of cheap natural gas recently. Coal is also harder to transport, dirtier, and the modern plants needed to produce electricity from coal are costly. A recent report also shows that carbon-dioxide emissions from the energy sector dropped to their lowest levels in 20 years, a feat many experts credit to the increased use of natural gas.

As a result, natural gas has been creeping up on coal’s market share of energy production, which is bad news for jobs supported by the coal industry in some swing states.

“Natural gas prices have shocked everyone,” Lynch continues. “I don’t think either candidate knows what they’re going to do about coal mining.”

Energy exports. Last December, the Energy Information Administration announced a milestone. The United States become a net exporter of refined petroleum products for the first time since 1949, thanks in part to declining domestic demand and new oil discoveries in North Dakota and Texas.

[Read: Rising Building Material Costs Could Crimp Construction Gains.]

But as oil production and refining has ramped up in the United States, supply has far oustripped demand in nearby domestic markets, dually dampened over the years by increasingly fuel efficient vehicles and more recently by a sickly economy. As a result, many times distributors often find better sales environments abroad in energy-hungry developing countries in South America and China.

“If exports of fuels refined in America continue as a trend rather than proving to be a one-time anomaly, it will be a positive development for American energy security,” Charles Drevna, president of the National Petrochemical & Refiners Association, said in a statement. “It will also result in more American jobs, more tax revenue for government at all levels, and a faster recovery for our nation’s economy.”

But oil isn’t the only energy source America could export. The nation’s vast supplies of coal and natural gas are valuable to growing nations abroad. Still, not everyone is keen on sending energy sources overseas. For starters, transporting coal to ports would involve some not-so-picturesque byproducts and environmental concerns.

“There’s some opposition in Oregon to building better ports [equipped to handle the increased volume of exports],” Lynch says. “It’s partly NIMBY as in ‘We don’t want more coal trains going through our backyards’ and partly environmental as in ‘We don’t want China burning more coal.'”

With natural gas exports, some opponents fear shipping more abroad could push up prices here in the States. But, Lynch doesn’t see much logic in that.

“Nobody says don’t send lobsters to Boston to keep the price low in Maine,” he adds.

Nuclear. Nuclear energy provides about 20 percent of the nation’s electricity–a bedrock part of the electricity grid, according to experts–but lately, there’s been a lot of uncertainty about the future of the industry, especially when it comes to disposing of spent fuel.

With Yucca Mountain in Nevada eliminated as a candidate for a national repository for nuclear waste, nuclear power plants have no long-term option for storing waste. Instead, they now store the waste on site in pools or casks. Efforts are underway to identify a new site, but no time frame has yet been set.

A recent U.S. Court of Appeals decision ruled that a temporary solution is not good enough to meet federal environmental standards. As a result, the Nuclear Regulatory Commission has halted issuing new licenses for nuclear power plants, putting at risk the expansion of nuclear power in the United States.

Although the decision doesn’t immediately affect any power plants, the speed bump could push back application processing for a year or more.

“What the impact [of the court ruling on potential future plant licenses or renewals for existing licenses] will be is hard to say,” says David McIntyre, a spokesman for the NRC. “On new reactors, there are only three on schedule to be completed over the next couple of years and hopefully we’ll have resolved this issue by then.”

In the meantime, the NRC is focusing on addressing the court’s ruling, McIntyre stresses. The agency’s response, and hopefully more certainty for the industry, should be coming out soon.

Until then, new nuclear energy reactors–and the future of the industry–are on hold indefinitely.
