Researchers say ocean winds could power all of human civilization

But the new research suggests that if the wind energy flowing over the oceans can be converted into electric energy then, it is sufficient enough to power the human civilization.
The research was supported by the Fund for Innovative Climate and Energy Research and an Carnegie Institution for Science endowment.
But extracting efficient energy from wind involves more than putting turbines in the path of gale-force winds.
Most of the energy captured by large wind farms originate higher up in the atmosphere and is transported down to the surface where the turbines may extract this energy.
Recent studies show that land-based wind farms will only provide 1.5 watts of power per square meter, not 7 watts as previously estimated. This limit occurs, because on land many natural and human structures are present which creates friction and this eventually slows down the wind speed. The authors point to other research which has concluded that the maximum rate of electricity generation for land-based wind farms is limited by the rate at which the energy is moved down towards the ground from high up in the atmosphere.
India vs Australia 2017, 2nd T20I: Hits and Misses Henriques scored 62 off 46 balls, including four fours and four sixes, while Head made 48 with the help of five fours and a six. India enjoy an excellent head-to-head record against the visitors, having won 10 and lost four out of the 14 matches played.
"The real question is", Caldeira said, "can the atmosphere over the ocean move more energy downward than the atmosphere over land is able to?"
The study used computer models which compared the total output of huge onshore wind farms in Kansas with the potential output of an equivalent-sized wind farm floating in the Atlantic ocean.
New research from the Carnegie Institution for Science has highlighted the "considerable opportunity" of developing offshore wind in the open ocean, which could generate up to three to five times as much energy as wind farms on land. This is largely due to the fact that large amounts of heat pouring out of the North Atlantic Ocean and into the overlying atmosphere, especially during the winter. By GCR staff0 CommentsA wind farm in the middle of the North Atlantic would be five times as efficient as one onshore and could provide limitless low-priced energy, says a paper published this week in the Proceedings of the National Academy of Sciences. That means, on an annual mean basis, the wind power available in the North Atlantic could be sufficient to power the world.
According to the researchers, the huge wind power resources identified in the study can provide strong incentives to develop lower-cost technologies that can operate in the open-ocean environment and transmit the electricity to land.
Mr Lee was quoted as saying the plans included blueprints for attacks to eliminate North Korean leader Kim Jong Un . Trump is expected to send a strong message to North Korea on his first trip to Korea as commander-in-chief.
I miss you, ' which went unanswered. "They are eager to get Kony, but after meeting you, they will do it". In 2012, Angelina Jolie was supposed to be part of a plan to arrest rebel leader Joseph Kony .
The Dodgers have a 2-0 series lead in the best-of-five divisional round following an 8-5 win over Arizona Saturday night. Finally, in his sixth big-league season, Arizona Diamondbacks left-hander Patrick Corbin will make his postseason debut.
Liverpool won just once in seven matches in all competitions while Mane was at the African Nations Cup in January. Mané has scored three goals in the four Premier League appearances he has made with Liveropool this season.
May, however, struck a confident tone during her speech on Monday, telling MPs: "I believe we can prove the doomsayers wrong". Losing the vote could see May resign as Prime Minister as she would hold an untenable position in Westminster.
Features that come with the update could also take up more processing power, and older phones may simply struggle to keep up. Since it's a beta version, there is no any option of the new emojis in the original Twitter app.
Around 900 people were injured when officers used rubber bullets and batons against voters at polling stations. It contributes much more in taxes (21% of the country's total) than it gets back from the central government.
The Pixel 2 XL will let you insert augmented reality virtual stickers that you can add into either photographs or videos. The main highlight of Pixel 2 is its camera, DxOMark Mobile has given the highest rating to second-gen Pixel smartphone.
And while that sounds positive, Australia still needed to step up the intensity to ensure it progresses with certainty. Socceroos boss Postecoglou took a huge risk by benching his best player in Aaron Mooy for this crucial qualifier.
Not stopping there, Donald Trump made a cryptic remark that appeared to hint at a potential military strike. Presidents for allowing the Democratic People's Republic of North Korea to build a nuclear missile program.
Saudi Arabia and the United States are highly critical of what they consider Iran's aggressive behaviour in the Middle East. Both Washington and Saudi Arabia accuse Tehran of aggressive and disruptive behavior in the region.
Richard Thaler wins Nobel prize for economics
Hansson said he did not believe there was systemic gender discrimination, but we are concerned; we are taking measures.. The Nobel committee said Thalers work shows how human traits affect individual decisions as well as market outcomes.
