In this paper, the fuel less generator just as the name implies is a power generating system that doesn’t require any kind of fossil fuel for its operation. It is safe to say the fuel less generator is a zero-carbon energy system with two major categories; Dynamic Fuel less Generators and Static Fuel Less Generators. The constructed 1kVA Fuel less Generator comprised of a 240W Brushed Direct Current Motor, a 1kVA Alternator, Couplings, Flywheel, 12V 100AH Deep Cycle Battery, 12V 4A Charging Panel or Rectifying circuit (AC-to-DC), Automatic Voltage Regulator, Frame, and other accessories. The Brushed Direct Current Motor was directly coupled to the alternator with the flywheel in-between, also a digital thermometer was connected to the Brushed Direct Current Motor and alternator to monitor their temperature. A digital Direct Current Ammeter and Voltmeter were connected in series with the 12V 100AH Battery and across the Brushed Direct Current Motor terminals respectively to observe and obtain readings of the fuel-fewer generators. A digital energy meter with a current transformer was also connected between the power output of the alternator and the 5A single pole circuit breaker to obtain output parameters such as Voltage, Current, Frequency, Power Factor, and energy consumed. A handheld Digital Tachometer was used to obtain the speed of the fuel less generator during testing. Various tests such as the No-Load and Load Test, Temperature Test, and Speed Test were carried out during the performance evaluation using varying loads from the range of 0W to 800W. During the test, it was observed that the temperature of the Brushed Direct Current Motor increased drastically when a load of 300W was introduced into the system and the generator had its maximum efficiency of 88.71% at the same 300W load. The fuel less generator was operated with and without the flywheel which gave an output frequency of 40Hz and 25Hz respectively. The construction of fuel less generator with the ability to be in perpetual motion and continually generate electric energy is achievable provided the motor speed, torque, and cooling system are properly calculated. This research can be used to replace the conventional gasoline generators used in residential buildings and by Small and Medium Entrepreneurs (SMEs). The inclusion of a direct-coupled flywheel, power torque formula, and temperature monitor and control play an important role in the development of an efficient fuel less generator.
