Nigerian innovator Emeka Nelson from Anambra State developed a 1,000‑watt water‑powered generator that can run for up to 6 hours on just one liter of clean water, capable of powering two‑bedroom home.
At age 12, Nelson tragically lost his best friend to lethal gasoline fumes during a power outage. That devastating loss ignited his determination to create a safer, emission‑free alternative to conventional generators.
With no formal education, Nelson started building a generator that runs without fuel, only water. He began by using reclaimed parts from roadside workshops, scrapyards, and community dump sites.
Nelson told BBC News Africa that he worked on the project for 16 years.
His innovation uses water, which is pressurized to spin a turbine at roughly 860 RPM, generating electrical current supported by a small battery used for startup and stabilization.
Nelson operates from a modest workshop in his residence, crafting prototypes and refining designs.
He also developed machines that convert plastic and farm waste into fuel, methane gas, and building materials.
Nelson’s innovation has garnered attention from BBC Africa, and has been featured in prominent Nigerian media, including Vanguard, BusinessDay, and others.
In an interview with BBC News Africa, Nelson hopes to evolve his water-powered generator from powering a home to providing off‑grid community energy.
He told the BBC, “This generator that uses water instead of petrol, that fuel that sometimes is almost as expensive as gold, do not entirely render petrol useless. But if you no longer have to worry about petrol, why not?”
