Wind electronic bring you the very best of power supply generator is fuelless generator with 1 year guarantee it can run for 24 hour non stop no fuel no oil just start it and enjoy your self 6kva 80,000STRACT: This research effort focus on comparison of two prototype designs, constructionand performance evaluation of V-belt and direct coupling fuelless power generating set. Searchfor renewable energy is important as the fossil fuel depletion as been noticed. There arebasically three ways of transmitting mechanical power from one point to another. Belt andpulley drive, Gear and chain and direct coupling. The two power generating sets were locallyconstructed at the Federal College of Agriculture, Ibadan Nigeria. These researches technicallyinvestigate two out of the three ways of mechanical power transmission system (Belt & Pulleyand Direct Coupling Design). The evaluation of the work shows that coupling design of powerfuelless generating is better than Belt and Pulley design of the generating set with efficiencyrange of 0% -89.9% for direct coupling while 0% - 73.23% for V-belt desig
