Ppt Presentation on Hydrogen based Fuel cell

Ppt Presentation on Hydrogen based Fuel cell •Hydrogen fuel cells are one of the most promising up-and-coming clean power sources today. Fuel cells have been used for decades on NASA spacecraft •A fuel cell consists of a central electrolyte layer, sandwiched between two catalyst layers. Various materials for these layers are used, but the basic process is the same. When… Read morePpt Presentation on Hydrogen based Fuel cell

OPTICAL CAMOUFLAGE

This is a good presentation on Optical Camouflage for engineering students. Optical camouflage is a kind of camouflage in which one wears a cloth which projects the background so that he appears somehow invisible. You may have seen this in Harry Potter’s movie. The invisibility cloak renders the human partially invisible, when he/she slips beneath the shining, silvery cloak.
