Biking and eco-friendly device charging–two ideals of the eco-friendly modern lifestyle. Why not combine the two? That’s the big idea behind the RollerGen, a device that harvests the energy generated by biking for clean, green gadget charging.
According to Green Cleaning Ideas, the RollerGen (the brainchild of a California-based High Tide Associates) attaches easily to the rear wheel of any bike and can harvest enough energy to charge all your gadgets, and then some. With 30W of electrical power stored in a powerful little battery, the RollerGen is no wimpy kinetic charger.
Of the RollerGen, the company says: “Enables off-grid adventures. Centerpiece of emergency preparedness. Boasts Silicon Valley’s latest technology electromagnetics, battery chemistries, and power electronics” However, at $495, it is certainly not the cheapest.
