To find someone standing at your door offering a free car wash service is the biggest surprise for someone like me who considers it as the most hectic job. Well, it’s no reverie as Zhang Yu, a college graduate from Songyuli, Chaoyang District, in China, has made a solar-powered car washing machine for this purpose. He’s organizing a door-to-door car wash service with his two friends around Songyuli.

The mobile car wash system is fitted with solar panels and has an en suite battery that supplies sufficient power to it. As of now, the inventors wish to get their machine patented. Moreover, they are looking for a manufacturer who could mass-produce these machines. After spending 10,000 Yuan in devising and assembling the tricycle with a solar power generator, now what Zhang needs to manage is the water usage and equipment maintenance costs only.
