Balsa wood is very lightweight and stiff, and it is perfect for making experimental wind turbine blades.

The Solar Thermal Exploration Kit is modeled after a domestic solar water-heating system. Explore variables such as box color, light intensity, tube design, rate of water pumping, and amount of time it takes to heat the water. Learn about what makes a solar water heating system more or less efficient.

Build a wind-driven car to explore propulsion and renewable energy concepts.

A small scale demonstration of renewable energy, this wind generator can be used with a voltmeter or datalogger to measure and monitor output.

With this Solar Cell Kit, you can harness the power of the sun.

Explore wind or hydro energy with our horizontal wind turbine lab.

Generate your own sustainable energy by converting common organic waste into biogas with this easy-to-use kit.

Use the PEM Electrolyzer to produce hydrogen and oxygen using only pure water and an external power source. Take your pick of power sources, all available from Horizon: small solar cell, wind turbines, fuel cells, mechanical hand cranks, or batteries. Using the high-tech proton exchange membrane, this tiny electrolyzer will produce hydrogen for use in any classroom or laboratory activities.
