Time to nail the number one problem of green energy

ONE of the frustrating things about renewable energy is that there is so much of it available and yet we utilise so little. Every minute, enough solar radiation hits the earth to meet global energy needs for a year. Wind energy, too, could single-handedly power the planet.

Why don't we harvest this bounty and end our dangerous reliance on coal, oil and gas? One of the main reasons is the storage problem. Whereas fossil fuels conveniently package up chemical energy for release on demand, wind and solar only generate electricity at the whim of the weather.

What's needed is a way to store surplus wind and solar energy. That much has been obvious for years, but there are signs that the problem is finally reaching its rightful place - at the very top of the renewables agenda. Technologies are advancing, particularly liquid-air storage (see "Saving renewable energy with air"). Investment is pouring in. And outdated regulations that have acted as a drag are being swept away. Anyone who tells you that renewable energy will never be reliable enough to replace fossil fuels is increasingly telling yesterday's story.

Driverless car concept gains traction at CES

LAS VEGAS: Automakers and technology firms are jumping on the bandwagon of the driverless car, which remains a concept as well as a platform for new technologies to improve safety on the road.

At the Consumer Electronics Show in Las Vegas this week, Toyota and Audi showed off their ideas for autonomous vehicles, in the wake of the push by Google on its driverless car. And others may follow suit.

Toyota drew considerable attention with its electronically gussied-up Lexus sedan, equipped with a host of sensors and cameras that can detect what is around the vehicle.

"It has the ability to drive itself, but we won't allow it," said Jim Pisz, corporate manager at Toyota North America.

Pisz said the technology is similar to Google's with the use of electronics, but that "the Google focus is on software mapping, that's what they're really good at. Toyota focuses on safety programs and more integrated programs."

The Japanese automaker maintains that its 2013 Lexus LS, also being shown at the expo, already has "the world's most advanced pre-collision safety system" but its driverless cars are only being used in closed research centres, unlike Google's publicised road tours.

The growing use of advanced electronics for auto safety, communications and entertainment has prompted a record eight automakers to attend the Las Vegas show, along with dozens of firms working on related products and services.

"Electronics are vital to our cars. Today's cars are rolling computers," Audi executive Wolfgang Duerheimer told reporters at CES.

The German automaker's Ulrich Hofmann told AFP that the new technology "helps the driver in situations where it's boring to drive, and leaves you to drive when it is fun."

At the Las Vegas tech confab, Audi showed its concept for a driverless vehicle in a simulator.

Hofmann said an autonomous car could be developed within five to eight years but noted that "there are a lot of regulatory and legal issues."

Ford Motor Co. researcher Pim van der Jagt said the US auto giant halted its program on driverless cars several years ago.

The concert "seemed so far out, it didn't make sense having big teams working on it," he said, but added that "now, with the interest in the Google car, politicians are starting to speak about it" and Ford has resumed its program.

Nevertheless, "a full autonomous car is far out, and may even never exist," van der Jagt said.

Audi engineers say they can envision an on-off switch which could be used in traffic jams on highways, where vehicles could join a sort of motorcade traveling at identical speeds, freeing a driver for a few moments.

In September, California Governor Jerry Brown signed a bill clearing the way for self-driving cars to jockey with human-operated vehicles to test the technology on the state's roads.

The state of Nevada in May issued a license plate giving Google's self-driving car the green light to travel along public roads there.

The growing talk of autonomous cars has sparked fresh interest in how the tech sector -- which has been under fire for fuelling "distracted driving" -- can improve auto safety and the driving experience.

"Everybody gets distracted at some point," said Steven Wenger of Mobileye, a company that makes equipment for crash avoidance for major automakers and as a consumer aftermarket device.

"Three seconds could save a person's life. We want people to be aware of these technologies which can help avoid accidents."

National Cathedral to wed same-sex couples

By Ben Brumfield, CNN

updated 2:37 AM EST, Wed January 9, 2013

STORY HIGHLIGHTS

• Same-sex couples have lined up to marry in city halls


• Washington National Cathedral is the site of presidential funerals


• Four presidents have had inaugural prayers there


• It is also a place of worship for the Episcopal Church

(CNN) -- When laws went into effect in three states for same-sex couples to marry, many were quick to line up at their city halls to exchange vows. Now they may do so in one of the nation's most prominent churches -- the Washington National Cathedral.

Most Americans know the house of God, also called the Cathedral Church of St. Peter and St. Paul, as a place where sacred rites are carried out on behalf of the nation. It has been host to the funerals of numerous presidents and of inaugural prayer services for four presidents, including Barack Obama.

But it is also an active house of worship in the Episcopalian Church, said the Cathedral's dean, Gary Hall. The denomination has developed a blessing rite that mirrors current wedding ceremonies for heterosexual couples and allows each bishop to decide to allow same-sex marriages in their churches or not.

Bishop Mariann Budde decided to allow the rite, since same-sex marriage is legal in the District of Columbia and now in neighboring Maryland as well, Hall said.

Same-sex marriage amendments in U.S.

HIDE CAPTION

It was Budde's decision that led Hall to create the same-sex rite.

He sees it as "another historic step toward greater equality."

The states of Washington, Maine and Maryland all legalized same-sex marriages in referendums during the 2012 general election. It was already legal in the nation's capital.

In March, the Supreme Court will hear oral arguments in two appeals cases related to same-sex marriage -- California's Proposition 8, which bans same-sex marriage and the federal Defense of Marriage Act, which denies federal benefits to same-sex couples.

The American Episcopal Church is intimately connected with the Church of England, which last week approved the advancement of male priests in same-sex committed relationships to the position of bishop. But those relationships must be celibate.

City halls in Baltimore; Portland, Maine; and Seattle erupted in celebration as the first same-sex couples tied the knot in December and January. Seattle's ceremony included 133 couples, who walked outside and down rain-slickened steps afterward, where they were greeted by cheers, confetti and a brass band celebrating the first day same-sex couples could marry in Washington.

To wed at the National Cathedral, one member of the couple must be baptized into the Church, and both must commit to a Christian marriage of "lifelong faithfulness, love, forbearance and mutual comfort."

N.Y.'s Cuomo pushing for much tougher gun law

A deal that would give New York one of the toughest gun control laws in the nation was being sought by Gov. Andrew Cuomo who, sources told CBS New York station WCBS-TV, was hoping to announce the plan Wednesday during his State of the State address.

The sources said Cuomo was negotiating furiously with legislative leaders in an attempt to reach a deal before the address.

The measures would be a response to gun violence in the U.S., including the tragic shooting at Sandy Hook Elementary School in Newtown, Conn., in which 26 children and adults were killed.

Sources said the package was expected to include new restrictions on assault weapons, stiffer penalties for using a gun to commit a crime, and new limits on the number of bullets in a gun magazine.

Cuomo's move comes as New York City Mayor Michael Bloomberg's Mayors Against Gun Violence released a new commercial to push for federal action.

It features Roxanna Green, the mother of Christina Taylor-Green, who was killed two years ago Tuesday in the Tucson, Ariz., massacre in which former Rep. Gabby Giffords was wounded.

"How many more children must die before Washington does something to end our gun violence problem?" Roxanna Green asks in the ad.

It would be quite a coup for Cuomo, a potential 2016 presidential candidate, to show progress on gun control as Washington stays divided on the controversial topic.

Late Tuesday night, a Cuomo spokesman said the sides still had not reached an agreement, but sources said there was talk of keeping the legislature in session the rest of the week to make sure a deal gets done.

Dead Lotto Winner's Wife Seeks 'Truth'

The wife of a $1 million Chicago lottery winner who died of cyanide poisoning told ABC News that she was shocked to learn the true cause of his death and is cooperating with an ongoing homicide investigation.

"I want the truth to come out in the investigation, the sooner the better," said Shabana Ansari, 32, the wife of Urooj Khan, 46. "Who could be that person who hurt him?

"It has been incredibly hard time," she added. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone."

Ansari, Khan's second wife, told the Chicago Sun-Times that she prepared what would be her husband's last meal the night before Khan died unexpectedly on July 20. It was a traditional beef-curry dinner attended by the married couple and their family, including Khan's 17-year-old daughter from a prior marriage, Jasmeen, and Ansari's father. Not feeling well, Khan retired early, Ansari told the paper, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She called 911.

Khan, an immigrant from India who owned three dry-cleaning businesses in Chicago, won $1 million in a scratch-off Illinois Lottery game in June and said he planned to use the money to pay off his bills and mortgage, and make a contribution to St. Jude Children's Research Center.

"Him winning the lottery was just his luck," Ansari told ABC News. "He had already worked hard to be a millionaire before it."

Jimmy Goreel, who worked at the 7-Eleven store where Khan bought the winning ticket, described him to The Associated Press as a "regular customer ... very friendly, good sense of humor, working type of guy."

Khan's unexpected death the month after his lottery win raised the suspicions of the Cook County medical examiner. There were no signs of foul play or trauma so the death initially was attributed to arteriosclerotic cardiovascular disease, which covers heart attacks, stroke or ruptured aneurysms. The medical examiner based the conclusion on an external exam -- not an autopsy -- and toxicology reports that indicated no presence of drugs or carbon monoxide.

Khan was buried at Rosehill Cemetery in Chicago.

However, several days after a death certificate was issued, a family member requested that the medical examiner's office look further into Khan's death, Cook County Medical Examiner Stephen Cina said. The office did so by retesting fluid samples that had been taken from Khan's body, including tests for cyanide and strychnine.

When the final toxicology results came back in late November, they showed a lethal level of cyanide, which led to the homicide investigation, Cina said. His office planned to exhume Khan's body within the next two weeks as part of the investigation.

Melissa Stratton, a spokeswoman for the Chicago Police Department, confirmed it has been working closely with the medical examiner's office. The police have not said whether or not they believe Khan's lottery winnings played a part in the homicide.

Khan had elected to receive the lump sum payout of $425,000, but had not yet received it when he died, Ansari told the AP, adding that the winnings now are tied up as a probate matter.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Authorities also have not revealed the identity of the relative who suggested the deeper look into Khan's death. Ansari said it was not her, though she told the AP she has subsequently spoken with investigators.

"This is been a shock for me," she told ABC News. "This has been an utter shock for me, and my husband was such a goodhearted person who would do anything for anyone. Who would do something like this to him?

"We were married 12 years [and] he treated me like a princess," she said. "He showered his love on me and now it's gone."

Tony Fadell: From iPhones to sexing up thermostats

After quitting Apple, the tech guru behind the iPod wanted to revolutionise our homes – starting with the humble thermostat

After you left Apple, you developed a "smart" thermostat. Was that always your plan?
Not at all! The plan was to retire with my wife, who also worked for Steve [Jobs], and spend time with our children. We didn't see them because we were working so madly at Apple. We wanted to build a house in Lake Tahoe. I wanted to design the greenest, most connected house that I could. That's when I found out about the thermostat problem. These devices had not seen innovation in 30 years. They were the same as the ones our parents had. I wanted something that was very different.

Your solution was the NEST. Tell me about it
It uses algorithms and sensors to remember the temperatures you like, create a custom schedule for your home and turn itself down when you are away. And you can use your smartphone, tablet or computer to control it remotely. We call it the thermostat for the iPhone generation. It has a big dial, not fiddly buttons.

Did Steve Jobs have any input?
I was going to talk to Steve about it. He knew we were working on something, but he didn't know what. When it was time to show him, he said he couldn't do it. Unfortunately, he died just a few weeks later, before he could see it.

Is the NEST just the start of a range of smart-home devices?
Absolutely. But if you look at what we did at Apple after the iPod came out, it took us five years to start thinking about the iPhone and two more years to finally ship it. I would love to make more devices, but our goal is to make the NEST successful first.

Who would have believed the iPod could turn into the iPhone, then the iPad?
Even I wondered how many people would buy an iPad. But you have to be at the right place in the cultural time. We plan a similar trajectory with the NEST, with the ways that emerging behaviours can happen in the home through interconnected devices. You can't start with all of these things at once because people's minds get blown. You start with very simple things, simple concepts, and then you can build on them.

Will people have to continually upgrade their thermostats, as they do with cellphones?
Unlike a cellphone, you're not going to change the NEST every 18 months! They are supposed to hang on your wall for 10 to 15 years. Our goal is to continue to improve it via software, and we have built tonnes of extra capability into this device to allow that to happen. For example, we have a new update that gives an energy report - it shows how you're doing compared with last month, and even compares you to your neighbours.

Was it your aim to raise awareness of the energy we waste heating our homes?
The NEST starts people thinking about how they're using energy in the home. But it's also a great party trick. You get people whipping out their phones and saying "Check out my NEST at home! Watch, I'm going to freeze my wife!"

Japan to buy Europe bonds to soothe debt crisis

TOKYO: Japan's new finance minister said that Tokyo would buy bonds issued by Europe's permanent bailout fund to help soothe the eurozone's debt problems and stabilise the yen.

Taro Aso told reporters the new government would tap foreign exchange reserves to pay for the bonds, but declined to say how much it planned to buy.

A finance ministry told AFP the bond buying could start as early as Tuesday, when the European Stability Mechanism (ESM) begins selling the paper, adding that Japan "will make a purchasing decision after seeing the terms of the issuance".

Japan, which counts Europe as a major export market, previously purchased billions of dollars in bonds issued by the ESM's predecessor, the European Financial Stability Facility.

"Stabilising Europe's financial crisis will eventually contribute to the stability of currency (prices) including the yen, and so we plan to keep purchasing ESM bonds using foreign reserves," Aso said Tuesday.

Europe's debt crisis has seen four countries ask for bailout cash to help pay their bills, while there were fears that others including Italy and Spain would follow suit as their borrowing costs surged.

However, those concerns have eased since September, when the European Central Bank promised to buy the bonds of struggling nations to keep rates down.

Also Tuesday, Japanese media reported that Tokyo was considering an extra budget worth about $150 billion to boost the limp economy, with about 40 percent of that figure directed toward public works projects.

The yen hit record highs around 75 against the dollar in late 2011, sparking panic among Japanese exporters whose goods are made more expensive by a strong currency.

However, the unit has since weakened and has seen a steep decline in recent weeks as the new government of Shinzo Abe, which took office last month after a landslide election win, vows to press the Bank of Japan for more aggressive monetary easing.

Reports Tuesday quoted Japanese executives expressing concern about the yen's recent tumble, saying the quick decline could pose a danger to the Japanese economy.

The business community, which had pressed officials for months to tame the surging yen, say a further plunge in the currency could shake investor confidence.

A weaker currency also makes fuel imports, which have risen steeply in the wake of Japan shutting down its nuclear plants, more expensive.

In Tokyo forex trading on Tuesday afternoon, the euro was up at 115.00 yen from 114.75 yen before Aso's comments, while the dollar bought 87.66 yen from 87.48 yen in morning deals.

Europe's permanent bailout fund was initially supposed to come online in July but only became operational in October after it was delayed by a challenge at the German Constitutional Court.

Cyanide linked to $1 million lottery winner's death

Urooj Khan, 46, won $1 million before taxes on an Illinois lottery scratch ticket in June.

STORY HIGHLIGHTS

• Urooj Khan, 46, won $1 million before taxes on an Illinois lottery scratch ticket


• He died suddenly weeks later; authorities first ruled his death "natural"


• Revisiting the case, they found he died of "cyanide toxicity," a medical examiner says


• Chicago police are investigating, but haven't made any arrests

(CNN) -- One day, Urooj Khan literally jumped for joy after scoring a $1 million winner on an Illinois lottery scratch ticket.

The next month, he was dead.

The Cook County medical examiner's office initially ruled Khan's manner of death natural. But after being prompted by a relative, the office revisited the case and eventually determined there was a lethal amount of cyanide in Khan's system.

"That ... led us to issue an amended death certificate that (established) cyanide toxicity as the cause of death, and the manner of death as homicide," Chief Medical Examiner Dr. Steve Cina said Monday.

Why did Khan, an Indian immigrant who was described as a well-liked, hardworking and successful businessman, die? And who is responsible?

Finding that out is now up to the Chicago police. No arrests have been made.

"We are investigating it as a murder, and we're working closely with the medical examiner's office," Chicago police spokeswoman Melissa Stratton said Monday.

On June 26, Khan was all smiles at a 7-Eleven in the Rogers Park section of Chicago. Surrounded by his wife, daughter and friends, he held an oversized $1 million check and recalled his joy upon playing the "$3 million Cash Jackpot!" game, where tickets sell for $30 apiece.

"I scratched the ticket, then I kept saying, 'I hit a million!' over and over again," the 46-year-old Khan said, according to a press release from the Illinois Lottery.

"I jumped two feet in the air, then ran back into the store and tipped the clerk $100."

The plan, he explained, was to use the money for his mortgage, paying off bills, a donation to St. Jude Children's Research Hospital and investing more in his dry cleaning businesses.

"Winning the lottery means everything to me," Khan said.

He would have to wait a few weeks to collect his actual winnings, which amounted after taxes to about $425,000. According to CNN affiliate WGN, that check was issued July 19, but Khan never got to spend it.

The next night, Khan came home, ate dinner and went to bed, according to an internal police department document obtained by the Chicago Tribune. His family later heard him screaming and took him to a local hospital, where he was later pronounced dead, the paper reported, citing the document.

That's where the Cook County medical examiner's office came in, investigating Khan's death because it was "sudden and unexpected," Cina said.

At the time, there were no allegations of foul play or evidence of trauma. So, following the office's policy, Khan's body underwent what Cina described as an "external examination (and) basic toxicology testing," neither of which turned up anything abnormal.

So the medical examiner ruled Khan had died of arterial sclerotic cardiovascular disease -- which encompasses incidents like heart attacks, strokes and aortic ruptures -- and that his manner of death was natural, according to Cina.

A few days later, a family member approached the doctor who had examined the body "and said they felt uncomfortable that it was being ruled a natural and they suggested that we look into it further," the chief medical examiner said.

"So we did that," he added. "Forensics is not a static field. If new evidence comes to light, we'll revisit cases."

That meant more in-depth toxicology tests. In early September, new screening results came back indicating cyanide in Khan's blood. With that, the official manner of death was changed from natural to pending, Cina said, and Chicago police got involved.

In late November, a more detailed blood analysis came back showing "a lethal level of cyanide" and Khan's death became a murder case.

Chicago police haven't offered details, including a possible motive, about what they call an "ongoing investigation." Talking briefly with CNN affiliate WBBM and the Tribune, Khan's widow described her husband as kind and exemplary.

Jimmy Goreel, who runs the 7-Eleven where the winning lottery ticket was sold, offered similarly glowing comments about Khan.

"I would never think that anybody ... would hurt him," Goreel told WGN. "(He was a) nice person, very hopeful and gentle (and) very hardworking."

Pakistan: U.S. drones kill 8 suspected militants

Updated 1:10 a.m. EST

DERA ISMAIL KHAN, Pakistan Several missiles fired from American drones slammed into a compound near the Afghan border in Pakistan early Tuesday, killing eight suspected militants, Pakistan officials said.

The two intelligence officials said the compound was located near the town of Mir Ali, in the North Waziristan tribal area.

One of the officials said an al Qaeda operative was believed to have been killed in the strike.

They spoke on condition of anonymity because they were not authorized to speak to the media.

North Waziristan, the area where the strike occurred, is considered a stronghold for insurgent groups operating in both Afghanistan and Pakistan. It is one of the few parts of the tribal areas that border Afghanistan in which the Pakistani military has not conducted a military operation to root out militants, despite repeated pushes to do so from the American government.

Tuesday's strike was the fourth since the new year began.

On Sunday, nine Pakistani Taliban fighters were killed when American missiles fired from several drones flying overhead slammed into three militant hideouts in another tribal area, South Waziristan.

The militant in charge of training suicide bombers for the Pakistani Taliban was believed by Pakistan intelligence officials to have died in Sunday's strike.

On Jan. 2, a drone strike killed a top Pakistani militant commander, Maulvi Nazir. He was accused of carrying out deadly attacks against American and other targets across the border in Afghanistan. But unlike most members of the Taliban in Pakistan, he negotiated a truce with the Pakistani military in 2009 and did not attack Pakistani troops or domestic targets.

The covert U.S. drone program is extremely controversial in Pakistan, where many in the country look at it as an infringement on their sovereignty. Many Pakistanis complain that innocent civilians have also been killed, something the U.S. rejects.

Islamabad officially opposes the use of U.S. drones on its territory, but is believed to have tacitly approved some strikes in past.

Meet Obama's Defense Secretary Nominee

President Obama nominated former Senator Chuck Hagel as the next U.S. secretary of defense. To those who haven't followed the Senate closely in the past decade, he's probably not a household name.

Hagel is a former GOP senator from Nebraska and Purple-Heart-decorated Vietnam veteran, but he wouldn't necessarily be a popular pick with Republicans in Congress.

At age 21, Hagel and his brother Tom became the next in the family to serve in the United States Army. They joined the masses of Americans fighting an unfamiliar enemy in Vietnam.

In his book, he describes finding himself "pinned down by Viet Cong rifle fire, badly burned, with my wounded brother in my arms."

"Mr. President, I'm grateful for this opportunity to serve our country again," Hagel said after Obama announced his nomination Monday.

In 1971, Hagel took his first job in politics as chief of staff to Congressman John Y. McCollister, a position he held for six years. After that, he moved to Washington for the first time, where he went on to work for a tire company's government affairs office, the 1982 World's Fair and in 1981, as Ronald Reagan's Deputy Administrator of the Veterans Administration.

Obama's Defense Nominee Chuck Hagel Stirs Washington Lawmakers Watch Video

He worked in the private sector for most of the 80s and 90s before his first election to the Senate in 1997.
Since the turn of the century, Hagel has followed a curvy path of political alliances that puts his endorsements all over the map. Hagel's record of picking politically unpopular positions could be a large part of why Obama is naming him for the job, as Slate's Fred Kaplan surmises the next Defense secretary will be faced with tough choices.

In 2000, he was one of few Republican senators to back Sen. John McCain over then-presidential-candidate George W. Bush.

After that election, Hagel fiercely criticized Bush for adding 30,000 surge troops to Iraq, in place of the bipartisan Iraq Study Group's proposal of a draw-down and regional diplomacy, which Hagel preferred. When Bush instead announced that more troops would go to Iraq, Hagel co-sponsored a nonbinding resolution to oppose it, along with then-Sen. Joe Biden, D-Del.

"The president says, 'I don't care.' He's not accountable anymore," Hagel told Esquire in June 2007. "He's not accountable anymore, which isn't totally true. You can impeach him, and before this is over, you might see calls for his impeachment. I don't know. It depends how this goes."

Hagel's fierce opposition to America's involvement in Iraq – he called it one of the five monumental blunders of history, on par with the Trojan War – will be of substantial importance as the Obama administration charts our course out of Afghanistan, deciding how to withdraw the last of the troops in 2014 and how much of a presence to leave behind.

Hagel's support for McCain, which was substantial in his competition against Bush, disappeared in the 2008 election. Hagel toured Iraq and Afghanistan with Obama during his first campaign for the presidency.

In October 2008, Hagel's wife, Lillibet, announced her support for the Obama team, after the Washington Post reported on her donations to his campaign. She donated again in 2012.

Before the 2008 election, Hagel wrote: "The next president of the United States will face one of the most difficult national security decisions of modern times: what to do about an Iran that may be at the threshold of acquiring nuclear weapons."
