Discover the future of bio-fuel cell technology! This device silently demonstrates how energy can be created from ethanol without combustion—and works, nonstop, for hours! Many fuel cells use hydrogen or methanol as fuel, but this fuel cell converts ...

The energy crisis is real! Update your curriculum today and bring the latest technological developments in solar energy research into your classroom. Dye-sensitized solar cells mimic the process that occurs in photosynthesis to harvest sunlight and c...

Bring the energy source of the 21st century into your classroom! Topics in chemistry, physics and engineering are studied as students learn about the electrolysis of water, how solar cells and fuel cells operate, mechanical work and energy conserva...

Explore the power of hydrogen! Sleek car demonstrates the technology behind how a fuel cell car operates. Transparent design allows students to see the inner mechanics of the car. Kit includes a refueling station that produces hydrogen and oxygen fro...

Race with the power of the sun! Give your students a hands-on experience with the future of transportation. Fast, clean-running solar vehicles may be just around the corner. The Photon Solar Racer can be built in one class period and raced in anothe...

One of the all time classic solar engines. It demonstrates the effect of infrared radiation with the spinning of its vanes. Just set it in bright light or the sun and away it goes. The hows and whys of solar motion are discussed in the accompanying l...

The world's largest solar bag-you've never seen a solar bag like this one! Our 50-foot-long, 3-foot diameter, black plastic solar bag holds over 350 cubic feet of air. Simply fill with air, tie off the ends, and let the solar energy of the sun heat t...

Use the sun to power a motor. The energy conversion from solar to electrical to mechanical energy will be made concrete for students using this simple kit. When the solar panel is placed in bright sunlight, it powers the motor. What can the motor pow...

We're talking hot! Students will be astounded at the temperatures and rate of increase achieved with this solar furnace. This solar furnace is constructed with two major components-a concentrator and a receiver. A 30.5-cm mirrored parabolic dish is t...

Students will love cooking their lunch using the unlimited supply of solar energy! No electricity, no flames, and best of all, no pollution. The Solar Oven's reflective panels concentrate the Sun's light into the cooking chamber at the base. The cham...

Run your radio and other battery-operated items with this unique solar panel. Convert solar energy into electrical energy to power all items that use C-size batteries or smaller. Multiple adapter tips enable the panel to be used with nearly all produ...

Using this miniature realistic wind turbine, students can evaluate the pitch, or angle, of the blades and then investigate how pitch and number of blades affects power output. Students also learn how the turbine protects itself under strong wind cond...

Creating power and energy from thin air? You bet! This affordable wind turbine demonstrates how energy can be generated by wind. Easy to assemble, this little-turbine-that-could produces enough electricity to power LED bulbs, a small power output boa...

As fossil fuels become more expensive and as we become more aware of their harmful effects on the environment, alternative forms of energy increase in interest. This wind generator is a mini-research unit on wind power and windmill design. The unit c...
