    Abstract: A ground-level vertical-axis wind generator introduces the use of reverse push-away hinges and soft sails specifically made for safe operation in a residential environment. The concave sails harness the wind energy, each one tensioned between two curved support arms, which connect to the central rotor via butt hinges. These hinges and soft sails yield safety to allow the wind generator to operate at ground level. The rotor drives an alternator included in the support structure of the wind generator via a gear assembly. The alternator generates the electricity and a direct current to alternating current power inverter converts the electrical current to match that of the residential utility grid. No installation is required; instead, it operates at ground-level in the backyard, which makes this safe and easy-to-assemble invention a cost effective alternative to harnessing free energy.
