power generator technologies
Portable generators are designed for use outside, are less expensive, and typically supply about 6.5-kilowatts of power. Most generators use either hydrogen, gasoline, propane, or diesel fuel. Hydrogen-fueled models generate power from tap water combined with electricity from a small solar panel or a mini wind turbine.
