This clever stove cooks a full meal for 25 people in just 30 minutes

Imagine a single stove that cooks an entire feast for 25 people in just half an hour. That's exactly what the Vishwaguru Chulha does. It can boil, fry, and even bake all at the same time, letting you whip up dal, fresh rotis, and even pizza simultaneously.

This seriously clever stove was designed by Sher Khan from Udaipur, India. Here's the wild part: Khan isn't some fancy engineer. He's an iron craftsman who left school after eighth grade. He saw women spending hours over hot fires, cooking different dishes one by one, and knew there had to be a better way.

He started tinkering 27 years ago, refining his design year after year. The result? A stove that's not only fast but also incredibly efficient. Traditional stoves might burn 10 kg of wood for a large meal, but Khan's invention uses just 2 kg and produces way less smoke.

This simple, smart solution earned him a patent in 2017. Now, over 1,000 Vishwaguru Chulhas are in use, powering everything from roadside eateries to small businesses. It's a quiet revolution in kitchen tech, proving that sometimes the biggest breakthroughs come from the most unexpected places.
