Meet the Energy-Saving Gadgets of the Future
Floors that generate electricity from footsteps. A GPS that outsmarts traffic jams. Innovations like these could be the next big thing–and we have student inventors to thank.
Pied Piper of Fish
Maurizio Porfiri wants to build robots that can herd fish like sheepdogs. Sound fishy?
Desert Military Bases Could Be Boon To Solar
Bases in California could host seven gigawatts of solar power farms, according to a new report.
Approved Reactors Could Power Up Nuclear Industry
Federal agency approves a license to build two nuclear reactors designed to provide cooling in absence of electricity.
Wind Power
In this activity, students will discuss the differences between the Bear Creek Wind Park and Bergey Windpower turbines. Students will learn the basic parts of a wind turbine and then build their own model wind turbine out of recyclable materials. Students will test their model wind turbines using three different-sized blades to determine which size harnesses the most wind.
Building A Solar House
Buildings that are called “green” or “environmentally sustainable” are designed to use energy as efficiently as possible. In Missouri, Washington University’s Tyson Living Learning Center achieves sustainability by incorporating green technologies in different ways, including the use of solar panels. In this activity, students will explore how solar panels work by building a simple circuit, a series circuit and a parallel circuit, using a solar panel to light a bulb and comparing which method yields the brightest light. Then students will build a solar-powered house using a shoebox, and test some variables to determine the most efficient way to harness solar energy to power a model home.
