Thames & Kosmos Solar Power Vehicles Electronics Projects STEM Kit, New in Box

Build your own solar-powered models and discover how solar cells generate electricity from light. Build six solar powered models including a locomotive, single-prop plane, bulldozer, helicopter, backhoe, and twin-rotor helicopter. A unique cradle holds either the solar panel or the battery, allowing you to switch out the solar panel for a AA battery (not included), depending on the strength of sunlight. You can even use the solar panel to charge up your own rechargeable AA batteries. The solar panel is position-able, so you can maximize its exposure to the sun to generate the most power. The 24-page color instruction book included in this kit gives step-by-step instructions for assembling the six model vehicles. The 177 building pieces included in this set are compatible with those in all Thames & Kosmos Construction Series kits, Physics Series kits, Wind Power, and Hydropower kits.
