MANCHESTER, England -- Chelsea's miserable run of form continued as Carlos Tevez netted his first Manchester United goal and Louis Saha came off the bench to win and convert a late penalty as Sir Alex Ferguson's side moved up to second in the Premier League with a 2-0 victory.

Tevez nipped in front of goalkeeper Petr Cech to head home Ryan Giggs' cross in first-half stoppage time before Tal Ben Haim was harshly adjudged to have fouled Saha in the area in the 89th minute.

The France striker duly converted the spot-kick with a strike down the center of the goal.

The Blues had to play the majority of the game with 10 men after John Obi Mikel was sent off for a studs-first challenge on Patrice Evra.

Chelsea were up against it from then on and it left Jose Mourinho's successor Avram Grant with a major task to lift a team shellshocked by the departure of their charismatic manager amid allegations of unwanted involvement from owner Roman Abramovich.

Meanwhile, England striker Michael Owen's fitness has again given cause for concern after he limped out of Newcastle's 3-1 win over West Ham at St James' Park.

The England striker asked to come off after 51 minutes after being largely a peripheral figure and will undergo a second scan on his injured groin.

Mark Viduka opened the scoring for the Magpies in the second minute but West Ham came back to claim a deserved equaliser through Dean Ashton.

However, the hosts went back in front four minutes before half-time when Viduka converted Charles N'Zogbia's low cross before the French midfielder scored the home side's third.

John Carew scored the opener and then went off injured as Aston Villa beat Everton 2-0 at Villa Park.

The Norwegian striker fired home in the 14th minute for his first domestic goal of the season before Gabriel Agbonlahor sealed the win with after 62 minutes.

The England Under-21 striker showed great control with his third goal in four matches against Everton to bring down Scott Carson's long clearance over the Everton defence and with his second touch slid the ball wide of the dive of Stefan Wessels.

A solitary strike from Kanu was enough to give Portsmouth their first away victory of the year and consign Blackburn to a second defeat in four days with a 1-0 win at Ewood Park.

Harry Redknapp's side had not savored a win on the road since a Boxing Day triumph at West Ham, since when they have suffered eight defeats and five draws. Kanu's 25th-minute goal was his third of the season.

Bolton manager Sammy Lee saw his side move off the foot of the table on goal difference by securing a point against Tottenham in a 1-1 draw at the Reebok Stadium.

Tottenham took the lead in the 33rd minute through Robbie Keane's first league goal of the season after a mistake by the returning Ivan Campo.

Campo made amends five minutes later by grabbing the equaliser with a thumping header into the corner following a free-kick from El-Hadji Diouf.

  

REYKJAVIK, Iceland (CNN) -- Iceland may be best known for world-famous musical export Bjork but there's a new star quickly gaining this island nation worldwide acclaim -- clean energy.

Waterfalls, volcanoes, geysers and hot springs provide Icelanders with abundant electricity and hot water.

Virtually all of the country's electricity and heating comes from domestic renewable energy sources -- hydroelectric power and geothermal springs.

It's pollution-free and cheap.

Yet these energy pioneers are still dependent on imported oil to operate their vehicles and thriving fishing industry.

Iceland's geographic isolation in the North Atlantic makes it expensive to ship in gasoline -- it costs almost $8 a gallon (around $2 a liter).

Iceland ranks 53rd in the world in greenhouse gas emissions per capita, according to the Carbon Dioxide Information Analysis Center -- the primary climate-change data and information analysis center of the U.S. Department of Energy.

Retired University of Iceland Professor Bragi Arnason has come up with a solution: Use hydrogen to power transportation. Hydrogen is produced with water and electricity, and Iceland has lots of both.

"Iceland is the ideal country to create the world's first hydrogen economy," Arnason explains. His big idea has earned him the nickname "Professor Hydrogen."

Arnason has caught the attention of General Motors, Toyota and DaimlerChrysler, who are using the island-nation as a test market for their hydrogen fuel cell prototypes.

One car getting put through its paces is the Mercedes Benz A-class F-cell -- an electric car powered by a DaimlerChrysler fuel cell. Fuel cells generate electricity by converting hydrogen and oxygen into water. And fuel cell technology is clean -- the only by-product is water. Watch the F-cell navigate through Reykjavik »

"It's just like a normal car," says Asdis Kritinsdottir, project manager for Reykjavik Energy. Except the only pollution coming out of the exhaust pipe is water vapor. It can go about 100 miles on a full tank. When it runs out of fuel the electric battery kicks in, giving the driver another 18 miles -- hopefully enough time to get to a refueling station. Filling the tank is similar to today's cars -- attach a hose to the car's fueling port, hit "start" on the pump and stand back. The process takes about five to six minutes.

In 2003, Reykjavik opened a hydrogen fueling station to test three hydrogen fuel cell buses. The station was integrated into an existing gasoline and diesel station. The hydrogen gas is produced by electrolysis -- sending a current through water to split it into hydrogen and oxygen. The public buses could run all day before needing refueling.

The bus project lasted three years and cost around $10 million.

The city will need five refueling stations in addition to the one the city already has to support its busy ring road, according to Arnason. The entire nation could get by on 15 refueling stations -- a minimum requirement.

Within the year, 30-40 hydrogen fuel-cell cars will hit Reykjavik streets. Local energy company employees will do most of the test-driving but three cars will be made available to The Hertz Corp., giving Icelanders a chance to get behind the wheel. Learn more about fuel cells »

"I need a car," says Petra Svenisdottir, an intern at Reykjavik Energy. Svenisdottir, 28, commutes to work from her home in Hafnarfjorour to Reykjavik. The journey takes her about 15 minutes if she can beat traffic. "If I didn't have a car I would have to take two or three buses and wait at each bus stop to arrive at work more than an hour later, cold and wet!"

Most Icelanders drive cars, says Arnason. Around 300,000 people live in a place about the size of the U.S. state of Kentucky. Transportation is limited to cars, buses and boats. "Everyone has a car here," Arnason says. And it's very typical for an Icelandic family to own two cars. Arnason drives a small SUV.

Fuel cell cars are expected to go on sale to the public in 2010. Carmakers have promised Arnason they will keep costs down and the government has said it will offer citizens tax breaks.

He figures it will take an additional 4 percent of power to produce the hydrogen Iceland would need to meet its transportation requirements.

Once Iceland's vehicles are converted over to hydrogen, the fishing fleet will follow. It won't be easy because of current technological limits and the high cost of storing large amounts of hydrogen, but Arnason feels confident it can happen. He predicts Iceland will be fossil fuel free by 2050.

"We are a very small country but we have all the same infrastructure of big nations," he said. "We will be the prototype for the rest of the world."

  

They make you wonder if anyone isn't cheating

ITEM: Ravens coach accuses Jets of cheating.

 

 

Once -- just once -- before you take the Big Dirt Nap, wouldn't you like to watch a sports event that you knew -- KNEW -- with utter, verifiable certainty was being played in strict accordance with the rules and the spirit of good sportsmanship?

I'm not talking about your kid's rec league soccer game, although you never really know with those, do you? I'm talking about watching a pro, college or international-level event in any game you care to name that is contested without illegal equipment, juiced or improperly procured players, spying, stealing and any other form of rulebreaking.

I mean, since you're paying or wagering your hard-earned and quite possibly counterfeit Benjamins, wouldn't you -- just out of curiosity -- like to know who the winner would be if everyone played clean and fair?

From the Balco boys and Bill "The Hills Have Eyes" Belichick to the Ramblin' Gamblin' NBA Ref to Formula One (McLaren was socked with a record $100 million fine for using rival Ferrari's secret data), the Women's World Cup (Danish team officials discovered two guys with video cameras lurking behind a two-way mirror in a hotel room where the team was to discuss strategy) and the Tour de France (half the field disqualified for doping), cheating is so pervasive and relentless that every score, result and -- especially -- exceptional achievement smells funny.

Bread it, damn it and fry it, you can't even have a traditional barroom argument anymore. Last week on FanNation, I got into a throwdown with my esteemed colleague Richard Deitsch about who is the better coach -- Belichick or Tony Dungy. Before Spygate, this was a
