question: In 2012, fuel cell industry revenues exceeded $1 billion market value worldwide, with Asian pacific countries shipping more than 3/4 of the fuel cell systems worldwide. However, as of January 2014, no public company in the industry had yet become profitable. There were 140,000 fuel cell stacks shipped globally in 2010, up from 11,000 shipments in 2007, and from 2011 to 2012 worldwide fuel cell shipments had an annual growth rate of 85%. Tanaka Kikinzoku expanded its manufacturing facilities in 2011. Approximately 50% of fuel cell shipments in 2010 were stationary fuel cells, up from about a third in 2009, and the four dominant producers in the Fuel Cell Industry were the United States, Germany, Japan and South Korea. The Department of Energy Solid State Energy Conversion Alliance found that, as of January 2011, stationary fuel cells generated power at approximately $724 to $775 per kilowatt installed. In 2011, Bloom Energy, a major fuel cell supplier, said that its fuel cells generated power at 9-11 cents per kilowatt-hour, including the price of fuel, maintenance, and hardware.

question: In their first divisional game of the season, the Patriots traveled to Giants Stadium, where they had not lost since 2000. On the first series of the game, the Jets drove to the Patriots' 13-yard line but the game remained scoreless after kicker Jay Feely missed a 31-yard field goal. Eleven plays later, the Patriots faced 3rd-and-goal from the Jets' 2-yard line, but a run for a loss by running back Laurence Maroney set up a 21-yard Gostkowski field goal to give the Patriots a 3-0 lead. After a Jets punt, the Patriots extended their lead to 6-0 on a 37-yard Gostkowski field goal early in the second quarter. The Jets responded with a 77-yard drive, highlighted by a 54-yard Laveranues Coles completion from quarterback Brett Favre, which brought them as close to the end zone as the Patriots' 1-yard line, but they again had to settle for a field goal; this time Feely completed the 21-yard attempt to cut the Patriots' lead to 6-3. The Patriots and Jets exchanged punts to end the first half. After a Patriots punt began the second half, the Jets started their next possession from their own 23-yard line. Three offensive penalties later, with the Jets at 2nd-and-25, defensive back Brandon Meriweather earned his first career interception on an errant Favre pass, giving the Patriots the ball at the Jets' 31-yard line. Despite a Kris Jenkins sack of Cassel to begin the drive, the Patriots moved into the red zone on a 22-yard completion to running back Kevin Faulk on a 3rd-and-9 play. Three plays later, Morris ran it in from the Jets' 1-yard-line for a touchdown, extending the Patriots' lead to 13-3. On an ensuing Jets punt, a 24-yard Faulk return set up the Patriots' next drive at the Jets' 39-yard line; nine plays later, a 28-yard Gostkowski field goal gave the Patriots a 16-3 lead and ended the third-quarter scoring. Beginning from their own 20-yard line for the sixth time in the game, the Jets drove into the Patriots' red zone and then cut the Patriots' lead to 16-10 on a 2-yard touchdown catch by wide receiver Chansi Stuckey. The Patriots' next drive went for 71 yards and ended on a 27-yard Gostkowski field goal to build the Patriots' lead to 19-10. This would be the final score, as the Jets' next drive, which included a 20-yard sack of Favre by Adalius Thomas, went three-and-out and the Patriots held the ball for the final 3:45 in the game. The win brought the Patriots' record to 2-0 and kept the team tied for first place in the AFC East. Gostkowski finished the day 4-for-4 on field goals and earned five touchbacks on six kickoffs.
Answer this question: Who scored the longest field goal in the first half?
answer: Gostkowski
