In the future, computers will use light to process large amounts of data faster than ever before. Robotic engineers are designing robots that look, feel, and act more human using realistic skin and hair with sensors. Future vehicles will be fuel efficient, zero emission, and use electronics to communicate and assist drivers through enhanced vision and collision warnings. Future phones will combine all mobile devices into one that may be transparent, flexible, self-cleaning, and shape-shifting. Scientists expect to gain more accurate weather predictions and eventually control the weather using new satellites and equipment. Renewable energy sources like sunlight, wind, and tides will provide most renewable energy either directly or indirectly from the sun.
