goals, CAMTech and its partner organizations bring in mentors who circulate
around the room, providing the hacking teams with expertise and an outside
eye. “They help make sure the teams are working on new ideas pertinent to
the focus of the hackathon, not ideas that have already been worked on,” Ms.
For all their cutting-edge savvy, the hackathons could not succeed without the right people. “It boils down to having passionate people who care
about the innovation process and want to make a change in healthcare,” Ms.

Carbon dioxide emissions are on the rise, and the
coal-fired power plants that produce the greenhouse gas aren’t going away any time soon. Globally, projects are trying to mitigate climate change
by capturing the carbon that these plants emit—
before it reaches the atmosphere.
Carbon dioxide accounts for nearly three-quarters of the world’s greenhouse gas emissions. From
2013 to 2014, carbon dioxide emissions increased
2. 5 percent. They will continue their upward trajec-
tory as the demand for coal, one of the cheapest
fuels, grows along with the global population, which
will surge 38 percent over the next four decades—
from 6. 9 billion in 2010 to 9. 6 billion by 2050.
Carbon capture and storage (CCS) projects col-
lect carbon waste and then trap it in the ground.
“CCS is the only known technology that will enable
us to continue to use fossil fuels and also de-car-
bonize the energy sector,” Maria van der Hoeven,
executive director of the Paris, France-based
International Energy Agency, said in October. “As
fossil fuel consumption is expected to continue for
decades, deployment of CCS is essential.”
As a disposal system, “CCS, like sewage disposal,
is absolutely vital,” says Jon Gibbins, PhD, director
of the UK CCS Research Centre and professor of
power plant engineering and carbon capture at the
University of Edinburgh in Edinburgh, Scotland.
One North American project has proven that
coal-fired power plants and CCS can be a success-
ful partnership. In October, Canada saw the open-
ing of the world’s first large-scale coal-fired power
plant outfitted with CCS technology. The Bound-
ary Dam Power Station in Saskatchewan, owned by
the utility company SaskPower International, burns
coal while reducing its carbon pollution by 90
percent. The 110-megawatt US$1.2 billion facility
will cut its own carbon dioxide emissions by about
1 million metric tons annually—the equivalent of
taking a quarter million cars off the road.
A project in Kemper, Mississippi, USA will be
the first large-scale plant with CCS in the United
States, where coal-fired power plants are the single
largest source of carbon pollution. The 582-mega-
watt Kemper County Energy Facility, set to begin
operations in 2016, plans to capture 65 percent of
