High-rise buildings would then display glass-windows with Solar system designed to adopt the rules or movement of program with fine awareness on global warming promoting also the knowledge on greenhouse effects.
Everything is systematically and easily done with the help of the computers that would somehow be the outlet of any communication displayed with colored receptions and finest resolutions.
Impressive latest technology advancement would definitely capture the attention of the whole world. Broadcast media, multimedia, all are but tubes to latest inventions that bringforth knowledge and skills to every human being.
However, unemployment may soon rise due to the latest technological inventions which would do and function what humans would.
