14 Grand Engineering Challenges | 4 Themes Advance Personalized Learning Sustainability Health Joy of Living Security Advance Health Informatics Make Solar Energy Economical
Enhance Virtual Reality
Reverse-Engineer the Brain
Engineer Better Medicines
Restore and Improve Urban Infrastructure Secure Cyberspace
Provide Access to Clean Water
Provide Energy From Fusion
Prevent Nuclear Terror
Manage the Nitrogen Cycle Develop Carbon Sequestration Methods Engineer the Tools of Scientific Discovery<br>
03
14 Grand Engineering Challenges Proposed in 2008 by a panel of accomplished scientists and engineers
Challenges are achievable and sustainable
Ultimate goals
Improve life on the planet
Universal accessibility
“a world divided by wealth and poverty, health and sickness, food and hunger,
cannot long remain a stable place for civilization to thrive.”<br>
04
Example 1: Provide Access to Clean Water Around 1/6 people do not have adequate access to water, and even more lack basic sanitation that is provided by clean water.
The biggest issues are the location, politics, and economics
Examples of Technologies that are being created in order to provide clean water:
Desalination : process that extracts salt from seawater.
Intelligent Irrigation
Small distillation units
Membrane chemistry
Smart monitoring<br>
05
Example 2: Make Solar Energy more Economical The sun is our biggest sustainability energy source of energy
Environmental clean
Solar energy provide less than 1% of the world total energy
Key issue is material purity which make solar energy expensive
Figure out new efficient ways to store the energy
Examples to make more economical
To use materials thick in one dimension, for absorbing sunlight, and thin in another direction, through which charges could travel.
Strategy envisions cells made with tiny cylinders, Light could be absorbed down the length of the rods, while charges could travel across the rods’ narrow width.
combination of dye molecules to absorb sunlight with titanium dioxide molecules to collect electric charges.<br>
06
Example 3: Securing Cyberspace Cybersecurity: one of the most important goals of our technology-dependent world
Current detection and prevention technologies in two totally different places
Current firewalls not advanced enough to take on modern hacking threats
Solutions:
Better, more difficult to hack software
New programming languages
Engineer checkpoints in the cloud for data to flow through<br>
07
Why the Challenges are Important Sustainability Health Joy of Living Security “Ensure the sustainability of civilization” and
“The health of its citizens”
Reduce “individual and societal vulnerabilities”
“Enhance the joy of living in the modern world” Overarching importance expressed in the themes
