• Advance personalized learning Instruction can be individualized based on learning styles, speeds, and interests to make learning more reliable.
  • Make solar energy economical Solar energy provides less than 1% of the world's total energy, but it has the potential to provide much, much more.
  • Enhance virtual reality True virtual reality creates the illusion of actually being in a different space. It can be used for training, treatment, and communication.
  • Reverse-engineer the brain The intersection of engineering and neuroscience promises great advances in health care, manufacturing, and communication.
  • Engineer better medicines Engineers are developing new systems to use genetic information, sense small changes in the body, assess new drugs, and deliver vaccines.
  • Advance health informatics Stronger health information systems not only improve everyday medical visits, but they are essential to counter pandemics and biological or chemical attacks.
  • Restore and improve urban infrastructure Good design and advanced materials can improve transportation and energy, water, and waste systems, and also create more sustainable urban environments.
  • Secure cyberspace It's more than preventing identity theft. Critical systems in banking, national security, and physical infrastructure may be at risk.
  • Provide access to clean water The world's water supplies are facing new threats; affordable, advanced technologies could make a difference for millions of people around the world.
  • Provide energy from fusion Human-engineered fusion has been demonstrated on a small scale. The challenge is to scale up the process to commercial proportions, in an efficient, economical, and environmentally benign way.
  • Manage the nitrogen cycle Engineers can help restore balance to the nitrogen cycle with better fertilization technologies and by capturing and recycling waste.
  • Prevent nuclear terror The need for technologies to prevent and respond to a nuclear attack is growing.
  • Develop carbon sequestration methods Engineers are working on ways to capture and store excess carbon dioxide to prevent global warming.
  • Engineer the tools of scientific discovery In the century ahead, engineers will continue to be partners with scientists in the great quest for understanding many unanswered questions of nature.
