How do solar panels work?

The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.

Mini pulsed electric field device for water disinfection

In this video, it shows an HKUST engineering showing how an engineer goes from identifying problems to coming up with a viable solution. As you watch it, see how in less than 3.5 minutes he: Explains the origin of the problem (questions) Drawbacks of the electric field device for water disinfection(originally) Design problems (barriers) that needed to be considered in engineering solutions. How engineers think creatively

The Next Step in Nanotechnology

Nearly every other year the transistors that power silicon computer chip shrink in size by half and double in performance, enabling our devices to become more mobile and accessible. But what happens when these components can't get any smaller? George Tulevski researches the unseen and untapped world of nanomaterials. His current work: developing chemical processes to compel billions of carbon nanotubes to assemble themselves into the patterns needed to build circuits, much the same way natural organisms build intricate, diverse and elegant structures. Could they hold the secret to the next generation of computing?
