Fans got to submit their questions before the Q & A session and Lutz, who plays Emmett in “Twilight,” answered some randomly selected questions and made the fans swoon with his charm. Here are some of the questions he got to answer.

QUESTION: How do you feel about being part of one of the biggest movie franchises of all time?

KELLAN LUTZ: You know what? It’s a real, it’s an honor to be a part of something that fans are so loyal to and support. It’s a magic carpet ride. To all of us actors, I think we really are living in this “Twilight” zone and it really hasn’t sunk into how big of a phenomenon it is.

Q: What is you favorite part of playing the role of Emmett?

KL: I love how much fun he gets to pick at Bella, especially in “Eclipse.” Kristen Stewart is amazing. Just to make her laugh when we were shooting and have her crack up. She would be like “I’m sorry Kellan, I can’t take it!” It’s so funny. It’s fun.

Q: What is it like playing a tough big brother?

KL: I have a lot of experience playing a tough big brother. I have a large family and I got picked on growing up and I did some picking on the little ones. So it’s always fun playing the big brother role, especially trying to crack jokes on Rob when he doesn’t get it. Again, we have such a great cast and we’re all, without any of us it wouldn’t be the family that we’ve forged.

Q: What is your favorite non-Emmett scene in “New Moon?”

KL: I’ll have to say just watching the Volturi. I never got the chance to meet them. But Michael Sheen’s amazing. I finally got to meet them while shooting “Eclipse,” and they are a great group of actors.

Q: Do you have any secrets you can share with us about “Eclipse?”

KL: I’m topless throughout the whole movie, pretty much!

Q: What are your plans for after “The Twilight Saga” ends?

KL: I’m gonna cry and be depressed. I love being a part of this franchise. To have all you guys, fans, and to play Emmett…I wake up happy everyday and I’m not sad. But when it’s all said and done, I want to be the next action star. I want to play Jason Bourne.

The speech, delivered at MIT’s Kresge Auditorium, praised the school’s faculty members and students for their commitment to energy research and achieving new advancements in clean energy technologies. He spoke about his excitement after touring the school’s Energy Initiative program laboratories and the benefits that these new technologies can bring to the world.

“Windows that generate electricity by directing light to solar cells; lightweight high-power batteries that aren’t built but are grown. That was neat stuff. Engineering viruses to create batteries; more efficient lighting systems that rely on nanotechnology; innovative engineering that will make it possible for offshore wind power plants to deliver electricity even when the air is still,” said Obama.

He pointed out that every country has recognized that the world’s energy supplies are growing scarcer and “that’s why the world is now engaged in a peaceful competition to determine the technologies that will power the 21st century. The nation that wins this competition will be the nation that leads the global economy,” he said. “I am convinced of that. And I want America to be that nation. It’s that simple.”

Obama also promoted Ricovery Act Investments that are creating advancements in wind energy as well as creating jobs. He said the Act includes $80 billion to create thousands of jobs for Americans developing new battery technologies for hybrid vehicles, modernizing the electric grid and doubling the country’s capacity to generate renewable electricity.

Susan Hockfield, the president of MIT, said that having Obama speak about renewable energy at the university can motivate more students in getting involved in new energy technology and policy development.

“It’s enormously energizing. The Energy Initiative has become a real centerpiece at activities here at MIT. And having the president here to make a major statement about energy really confirms and amplifies the work that’s already been done on campus,” said Hockfield.

MIT’s Energy Initiative program director Ernest Moniz said that energy research conducted around the country has helped the US be a frontrunner for leading the global economy in clean energy. However, he said there’s still much work to be done.

“United States still has, in my view, the world’s foremost science, technology and innovative system. In the other hand, we cannot be complacent. We can compete as long as we have the resources sustained and commitment from the highest levels, which the president demonstrated today,” explained Moniz.

Obama has been the second president to visit MIT but was the only one who met with faculty members and received a tour of school laboratories. The previous presidential visit was made by Bill Clinton who delivered a Commencement address in 1998.
