It's a fact of physics: There's AC and there's DC. And in the process of converting
electricity from one form to the other - going from the AC power that comes out of the
wall socket to the DC power that runs your laptop, for instance - significant energy is
lost. Maybe as much as 10 percent. How to overcome this waste? Use gallium nitride
instead of silicon in the power conversion modules. That's the solution that Google
Ventures, Kleiner Perkins Caufield & Byers and other investors are betting $38 million
on, backing a startup called Transphorm.
Transphorm says it has optimized gallium nitride for power electronics and "has
developed novel devices such as transistors, circuits, and complete modules that
include all the components needed to replace conventional systems," according to MIT's
Technology Review.
"The impact is huge - on the grid, on the planet," Tranphorm chief Umesh Mishra said at
an event at Google headquarters, according to the San Francisco Chronicle. "Whenever
you use electrical energy, you're paying a hidden tax due to the inefficiencies of
power conversion."
The Transphorm technology would also work, of course, in the other direction: energy
stored in battery packs in electric vehicles like the Nissan Leaf has to be converted
to AC to run the motor, and solar power systems use inverters to turn DC power into AC
for household use. Gallium nitride would help make those systems 90 percent more
efficient - and lighter and less bulky - Transphorm says. Those brick-like laptop
adapters might finally be a thing of the past.
As good as this all sounds, Grist's Todd Woody notes that long design cycles could mean
that even if everything Transphorm says is true, gallium nitride will arrive slowly in
devices. And as with most new technologies, gallium nitride modules are likely to be
expensive until volume ramps up.

Four months after a horrific crash
Four months after a horrific car crash nearly killed him, Justin Corter of Cold Spring
continues to recover.
"It's a miracle," says his mom.
Oct. 10, 2010 stands out on the Corter family calendar.
His mom, Donna Corter was in church that morning.
Justin, 20, had hopped a ride with a friend, headed for town.
"His car was down, so she had come to pick him up. And I don't know exactly what
happened," Donna said.
They were driving along Rt. 191 when the car left the roadway and slammed into a tree.
"They hit the passenger side, Justin's side," Donna said.
Julie, the driver, was fine. "Justin broke her impact. He hit the tree and then she
slammed into him. When she slammed into him, she collapsed his lung on the left hand
side."
The extent of his injuries was staggering.
"He had two fractures of his scull. He had bleeding and swelling of his brain. His hip
had multiple fractures. He had facial fractures all over. The right eye orbital, the
socket of the eye, was completely fractured. The first time we saw him, the best way I
could describe his face was the eyes were so swollen and sticking out from the swelling
he looked like a goldfish, you know the ones with the big eyes? I never realized
someone's eyes could swell so bad," she said.
All these months later, his mom says, "He's still not 100 percent."
But he's come a long way. "If you could have seen him two months ago, laying in a
hospital bed, to where he is today. He was on a respirator. He was in a coma. He also
had a bruised spleen. The left lung was collapsed. And that week, he started to develop
pneumonia. It was a mess."
Was she afraid of losing him? "That thought never even crossed my mind. I could never
see him gone," Donna said. "There was one time that I can say I panicked ...They had a
throat tube...He coughed up the tube for the respirator."
Doctors said they'd have to put a new tube down, failing that, they'd have to do an
emergency tracheotomy. " I said: What will happen if you can't get a new tube down?
They said, ‘He will die.' That's when I think it finally hit me. I lost it that day,"
Donna said.
In the ICU for two weeks, Justin remained at CMC for a full month before being
transferred to John Heins Rehab on Nov. 2 .
"In the beginning, [a therapist] would hold pictures up, and it would be of a cell
phone and he would tell her a hot dog. He couldn't tell you what things were. I spent
many a day crying on the way home," his mom said.
Justin, his family, and the staff at John Heins continued to work hard. Nov. 30, he
was released from the hospital.
"He's come quite a distance," his mom said. "He's doing fantastic. He's scheduled to go
next week for his reaction test for driving." If he passes, he'll be one step closer to
reclaiming his driver's license, something he's hepped on doing.
"Through all of this, I think one thing is really important — prayers," said Donna.
Ministers, priests, everyone was praying for them. "I really do believe the power of
prayer is amazing," she said. "I could start crying at the outreach of everybody, the
community, our friends. It was an amazing journey.
"We received so many cards through all of this. And Justin was on so many prayer lists.
People were sending cards, we didn't even know them," Donna said.
A pre-school teacher for the First Presbyterian Church in Honesdale, Donna was touched
by the thoughtfulness of her four-year-old students who made a poster, saying, "We miss
you Miss Donna."
Her son's accident has changed her family, she said.
"We all look at things a lot different this year. We're all learning to look at things
a lot differently. With a bigger heart. We're very, very grateful for everything that
we received through all of this, and everybody's help."
