Wind-stream offers two types of human power generators. Both are based on transforming movement of the human body into electricity. The Human Power Trainer and the Human Power Generator are the solution to energy education in the classroom, failsafe backup power, and productive exercise. The human body can be highly efficient at delivering energy. Most adults can generate a steady 75 to 150 watts with spurts of double that power. The Human Power Trainer bike generator provides a sturdy, adjustable stand that raises and clamps the rear axle of your bike, with an adjustable friction wheel, a flywheel for steady power, and a DC generator that can deliver over 500 watts.
The stand has large and heavy rubber feet for stability and quiet. The generator will deliver 12V or 24V power depending on the battery it’s connected to (use higher gears with higher voltage). Charge your off-grid or RV household battery, or any portable battery pack. Stay fit and side by side save the Earth for the generations to come.
