Discover how to create a compact vertical-axis wind turbine with everyday materials in this detailed step-by-step guide. Watch as we build composite turbine blades, assemble a helical rotor, and ...

How can open ocean currents generate energy? Ocean currents contain kinetic energy that can be converted to electrical power using turbines. This is similar to offshore wind farms, or wind turbines ...

Today we’re making a homemade potato battery and testing how much power a potato can really produce. Using simple materials like zinc and copper, we build a working circuit and measure the voltage ...

If you’re considering whether solar panels are worth it, one of the first questions to ask is: how much electricity can they actually generate? The answer depends on a few key factors, from your solar ...

Solar panels and wind turbines give the world bountiful energy — but come with a conundrum. When it’s sunny and windy out, in many places these renewables produce more electricity than is actually ...

This chapter considers the extent to which renewable technologies might contribute to the future U.S. electric power supply. To come to conclusions about the level that renewables might contribute to ...

Researchers at Stony Brook University may have captured lightning in a bottle — or at least explained one of the theories of how it is created. Working with researchers in Spain and China, Stony Brook ...
