This spring, viagra buy a group of students completed a project focused on electricity. They learned how electricity is generated and how different kinds of circuits work. They wired lamps, story built a bike generator and created a solar charging system. Working with the Enterprise Center, a West Philadelphia minority business incubator, students analyzed lighting needs along the 52nd Street business corridor, a major commercial thoroughfare in West Philadelphia. Then they designed and built two different energy efficient lighting prototypes, and presented their designs to the Enterprise Center, the City Councilwoman Jannie Blackwell, a local Community Development Corporation, and representatives of the Philadelphia Department of Commerce. In the next phase of the project, students will develop a business and production plan, building on previous work and community feedback.
