And the 14 Grand Engineering Challenges of the 21st Century Are..

Before you can save the world, you'd better write a to-do list so nothing gets overlooked. Some of the world's brightest minds have done just that by laying out this century's greatest engineering challenges.
The panel of 18 engineers, technologists and futurists included Google co-founder Larry Page and genomics pioneer J. Craig Venter. They spent more than a year pondering how best to improve life on Earth and came up with 14 Grand Engineering Challenges, a list the National Academy of Engineering deemed so momentous it should be capitalized.
The list, announced this afternoon, addresses four themes the committee considered "essential for humanity to flourish" - environmental sustainability, health, reducing our vulnerability and adding to the joy of living.
"We chose engineering challenges that we feel can, through creativity and committment, be realistically met, most of them early in this century," said committee chair William J. Perry, the former Secretary of Defense who teaches engineering at Stanford University. "Some can be, and should be, achieved as soon as possible."
What are they?
Make solar energy affordable.
Provide energy from fusion.
Develop carbon sequestration methods.
Manage the nitrogen cycle.
Provide access to clean water.
Restore and improve urban infrastructure.
Advance health informatics.
Engineer better medicines.
Reverse-engineer the brain.
Prevent nuclear terror.
Secure cyberspace.
Enhance virtual reality.
Advance personalized learning.
Engineer the tools for scientific discovery.
The committee, which also included such luminaries as futurist Ray Kurzweil and robotics guru Dean Kamen, decided not to make any predictions or focus on gee-whiz gadgets. They felt it more important to outline broad objectives that might influence research funding and governmental policy.
The 14 challenges they laid out were culled from hundreds of suggestions from engineers, scientists, policymakers and ordinary people around the world.
"Meeting these challenges would be game changing," said Charles M. Vest, president of the NAE. "Success with any of them could dramatically improve life for everyone."
So... what should we check off first?
