Powerhouse Green Essentials edition

Thirty of the best experiments and the ten most important building projects from the original Power House kit are presented in this new Green Essentials Edition.
The ten building projects include: the power house itself, a greenhouse, a solar cell array, a passive solar collector, a solar oven, an air conditioner, a refrigerator, a hydrometer, a lemon battery, and a wind power generator.

Experiment with the heating, cooling, and insulation of the house and greenhouse. Test passive solar collection methods with a solar collector. Assemble a solar power array to explore active solar power with photovoltaics. Build a model refrigerator and air conditioner to learn about heat transfer. Experiment with a lemon battery to learn about power storage. Set up a wind turbine to generate electricity from the wind.


• build a working wind turbine
• harness mechanical energy to lift weights
• generate electricity to light an LED and charge a battery
• learn the physics of wind turbines
• discover how wind occurs and why it is such a promising energy source

Physics Solar Workshop, Kosmos

Physics Solar Workshop explores the topic of solar energy, focusing on photovoltaic cells. By building 12 models and conducting 30 experiments, you will learn how solar cells transform light into electrical energy, and how motors and mechanical devices can optimize the work done by this energy. You will build different types of vehicles and machines to demonstrate how gears can convert and transform power for different needs. There are 320 parts, which are also compatible with the other kits in our Physics line. The 64-page book offers illustrated instructions for the projects. Developed with Greenpeace in Germany.

• build 12 models, including a solar-powered tractor, truck, treaded vehicle, car, elevator, drawbridge, fan, airplane, mobile crane and construction crane
• learn about harnessing and using solar power
• learn about motors and simple machines

Stirling motor met alcoholbrander

Observe firsthand the conversion of heat into mechanical and electrical energy. The Stirling engine uses an external heat source to create a temperature difference that produces energy, moving the pistons and a flywheel so the engine runs. Easily see all working parts of the engine. Quality construction means this model will last through many uses. No assembly required. Includes instructions.
